waidy the tail, bat flatteuad at the auterior per' 
tioij. Thu head proper armed with powerfal jaws 
is placed iu the oeutre of a half-aphere, aud is an 
uhlUHU knob, about Sye-aiie-hundredtha ( OSU) of an inch 
diameter and projectioD. The undetaide of the body 
fur the hrst four aagoieuta from tlie head about three- 
teutha ot au inch ( 30UJ ia quite Hat, the diviaioui 
between the aegmeiita being alnioat non eat. 
'The lart four Hegmenta are developed into knobs 
witn a alight indentation parallel to ibe axis of the 
body, dividing each one forming rudimentary feet. 
Krum point to point the last two segments are 
about one-tenth of au inch apart when the creature 
IS at rest, it can, however, bring them together or 
extend them to about two-tenths ('200}, 
The bumps on the back are not exactly opposite those 
beneath, bnt ate placed on the half-lap, so that a side 
view suggests a screw. Tbe tail ia a protrnbtranou on 
the last segment, it is about two one-hundredths ('0201 
01 au mob in diameter and projection, Ooiuiting bead 
and tail there are thirteen segments- 
Fupa : tbe colour is a yellowish white, whioh 
becomes darker as tbe insect approaohos its final obange. 
A well- developed specimen measured sixty-five one- 
baudiedths ('HBO) of au inch In length, but sumo 
are only ('fiOOjbalf an inoh long. 
Tbe elytra are folded under the ei'cond pair of legs 
and overlie the third. Tbe sntennn are carried back 
over legs and elytra and extend back as far as the 
posterior portion of the wings which are overlain 
by tbe former of tbe seoonj pair of legs. 
The whole ia enclosed in a transparent membrane 
through whioh the form clearly shows, all tbe details 
of tbe future beetle being diaoernable. 
The beetle (imago) perfect insect. — The female is 
a little larger than the male, meainring ft-om fl fty-five 
('55U J tusixCy -three ( '630) hundredths ot an inchin length, 
while the male is only from fifty (-600) to fifty-five 
('650). Dr. Bidie gives a good drawing of the insect 
in his book, 
'The following is a desoriptiun ot the femsle ; it applies 
also generally to the male, only as before staled it 
is smaller. Tbe bead is depressed, emsll, flattened 
in front, with two white grey lines, formed by minute 
hairs, exieuding from tue roots ot the anteunn past 
tbe eyes. These are large, prominent, brilliant, oom- 
pouud lenses ; about forty-one tbousaudtbs ('040), and 
fliteen ('016) to twenty ( 020) tlionsandiha ot an inoh 
in diameter. 
'They are placed more to the side than to the front, 
just below the auteunai, forty-five ('016) thousandths 
above the mouth. They command a very wide field 
of view, the insect practically seeing all round at once. 
The autennie are two hundred and hfty (-260) 
thousandths to sixty ('230) in length ; filiform (re- 
Bombliug a piece of nlack silk thread >; eleven-jointed, 
covered witu inicrosoopio hairs incurved and poiuted 
at the up. The hrst joint is heavitr and etrooger 
than the rest; tbe Hvooud longer; the joints taper 
UP towards the head, tbis being nearly twice the 
diameter of the joini which fits into it. 
Ttie maudiblea are lorty-luur thousandths (•044) 
long tUirty-thrao thousandths (-033) broad at the base, 
verv poworlul, incurved at the point, whioh ia blunt 
BuOl rounded: each one when diaeeoted out is in 
shape like a boar’s head, the snout being curved downj 
they ate sparsely covered with bnstlea. 
The back of the hesfl is black, polished, and smooth 
with minute, oonoave, roMded iadenUtionsi it is 
free from hsiT. The pro-thorax is one hundred and 
twenty thousandths ('120) long on the underside one 
nuuured and eighty ('IbO; on the back, one hubJred 
and sixty ('160) in diameter ; it is wheii diiseoted out 
neaily Byhetioal, a portion being out off at one end 
to ahow‘^of junolion with tbe head, the eml 
IB also sliutd off for attochmeut to the m^o-thorax. 
it IB euvered with minute yellowish gray hairs 
partioularly noticeable on the underside, aud is marked 
on the back by three black spots the centre one being 
four to five times the.size of the outer ones, they ate 
just tbe aixe ot tbeae full stopa . < . . 
A pair of short strong legs spring from the pos- 
terior portiOD of the pro-thorax, they are fooi tentbi 
^■4UU) of aa iBQh levK. 
Tbe feet are armed with hooked bifid claws; the 
femur (thigh), in color black brown, is remarkably 
well dev^oped. The meso-thorax is very short and 
wrdged in between the pro- and meta-thorax giving 
just room fur tbe free attachment of the second 
pair nf legs. The meta is in shape ovoid ; on the 
underside from the termination the pro-thorax 1 1 
the anterior extremity of the abdomen ia two hundred 
thonsaudlha ('2U0) of an inoh. On the back tbe meso- 
and meta-ihorax are covered by the elytra, when 
the insect is at rest. They are in color black-brown 
under tbe wings. On the underside they are covered 
with a dark gray down ; two hues one on each sides 
of a yellowish white color, exteudieg from just below 
the anterior extremity of the elytra, almost on 
the divisiou line of the pro- sod meso-iborax te 
tbe second pair of legs, from whioh it curves back- 
wards over tbe meta-thorax to the third pair. 
The second pair of legs leave the body at the pos- 
terior portion of the meso-thorax olose to the first 
pair, they ate four hundred and thirty thousandths 
('480) long. 
The third pair arisiog from the posterior portion of 
the metii -thorax, have the femur particularly well 
developed, it is twenty ('020) in length, and as with the 
second pair, of a light brown color. The total length 
of the leg is BIX hundred and twenty-five tboosandths 
('623). All tbe tarsi (fset) are armed with olaws, and 
are black in color ; those of tbe first pair are booked, 
those of tbe second and third straight; this giving the 
beetle great power of holding on and forcing itself 
up against tbe wood itself it is devouring. The short 
stiff Lairs 00 the limbs enable the insect to clean itself ; 
the great length aud strength of the third pair of legs 
enable it to jump a considerable distance and as it 
springs off it often unfolds its wings. It seems to be 
all eyes and ears and is as active as a flea and re- 
quires no little skill to oatob it. 
The elytra (wing-sheaths) spring from the meso- 
thorax ; they are thin horny plates, ooveting the wings 
proper; they are tour-tenths ('400) of au inch long; 
from shoulder tip to shoulder tip two-teutbs ('206) 
broad, taperiog gently down down to fifteen One-bnn- 
iredths ('ISO) of an inoh at the posterior extremity, 
whioh is squared ofl:'. A spike projects about eight one- 
thousandths ('008) of an inoh on the outer extremity of 
each one. The marks on tbe back of the elytra are a 
bronze color, on a black background. Beginning at the 
anterior extremity they consist of a cross hue about 
two one-hundredths ('020) broad extending right aoroaa 
the bsok. It has a small, bright-yellow spot iu the 
oentre. 
Besting on the outer extremity of this oross lino are 
two dashes whioh with it forms a bracket 
tween the horns of whioh a with a muonmirvod 
top is inserted. The horns nearly touch the enclosed 
angle at the top of the The bottom of this 
almost rests on the yellow spot in the centre of tbe 
cross line from this point to the top of tbe is 
fifteen one-hundredths ('160). Posterior to ibis is a 
shorter much flattened and spread out at the 
top, which nos the point ooincideut with, but twenty- 
three one-hnnaredlhs (-280) from tbe yellow dot. 
A wedge of bronze color measuring one-tenth (-100) of 
an inoh base to apex, completes the marks on the elytra 
the base extends from spike to spike. 
The wings when the insect is at rest are oarefully 
folded under the elytra ; they are rather square at the 
top, taperiug lo a beautiful ouive to a somewhat 
rounded point. 
The length from the joDction with the body to the 
extreme tip is four hundred and forty-eight (*449) 
thousandths of an inch, and the extreme breadth is 
across the top one bundrod and fifiy*flve ous^thou* 
sandtbfl (*155). 
They are thin tranapareut irridoesent colorings. Tlie 
midrib of the wing is very powerfal, it ends in a 
^aped piece which enables the insect to extend or 
lur the wing at will, it is aided by another powerful 
nb at tbe anterior eztremitys The outer edge is fringed 
with minute hairs which are also spread over the 
upperside.
