cross the dark terminal space are shaded with 
light chestnut brown. iflind wings grey, with a 
broad dark chestnut band across the wing, inter- 
rupted by a whitish comma-like mark near the 
sub-costal vein; this band is followed by two 
whitish lines nearly obsolete at the sub-costal 
margin. Marginal space brown, with a dark 
chestnut spot at the anal angle. <A short pale 
grey line at the tip, and the fringe at anal angle 
dove color. Legs to the tibiee chestnut brown, 
thence pale grey. 
Ty. §8. EXCAECATUS.—ADbd. 
Palpi and head fawn color with a slight roseate 
tinge; thorax of the same color, with a chestnut 
colored dorsal stripe, tapering anteriorly, and on 
the metathorax a transverse patch of the same 
hue; abdomen fawn color with a dark brown 
dorsal stripe. Anterior wings fawn color, with a 
dark brown median patch, containing a blackish 
discal spot, of a darker hue anteriorly, inclined 
toward the inner angle, with a purplish line con- 
necting it with the base of the wing, and joined 
at an acute angle by a patch of the same hue, 
about the middle of the sub-median nervule ; two 
or three brown lines cross the middle of the 
nervules, nearly parallel with the median patch, 
followed by an irregular brownish band; margin- 
al space brown, with a small brown spot at the 
inner angle, above which are two or three black 
spots; there are also several blackish lines nearly 
following the direction of the nervules. Posterior 
wings rose color in the center, with a brownish 
patch at tip crossed by two or three short whitish 
lines; an ocellate black spot, purpled with pale 
blue near the anal angle, with two or three 
whitish lines between it and the inner margin; 
posterior margin fawn color. 
Under side light fawn color. Anterior wings 
roseate at the base; two or three brown lines, 
alternating with lighter ones shaded at the tip 
with white, cross the center of the nervules; mar- 
ginal space a dark fawn color with an orange 
colored patch near the inner angle. Posterior 
wings with two or three lines, identical in color 
and connecting with those on the anterior wings, 
followed by an orange band parallel with these 
lines. Expanse about three inches. Occur in 
May to July. 
Mature larvee which may be found about the 
last of September, is apple green, paler on the 
back, with numerous white-tipped granulations ; 
a stout bluish green caudal horn; seven pale yel- 
lowish oblique stripes on either side, the last one 
quite bright yellow and extending to the horn. 
Pup chestnut brown, smooth, with terminal 
spine. Transformation subterranean. 
Food: plants, apple, plum, will cherry, and 
sometimes found on the wild swamp rose.

Are the Lost Mandibles of Coleoptera 
Reproduced. 
On the 17th of January last, I took from a 
crevice in the bark of a pitch pine tree,a 9 speci- 
men of Catogenous rufous. A subsequent exam- 
ination showed me that the right mandible had 
been broken outwardly—carrying the antenna 
with it—and remained attached to the head by 
only one—the outer—corner. In its place a false 
mandible or process had grown, slightly longer, 
more flattened and Jess pointed than the original. 
The outer edge had grown to the broken base of 
the mandible. The extremity was hard, dentated 
and fairly calculated to take the place of its pre- 
decessor. It isa well known fact that in many 
species of animals—notably crustaceans—lost 
members are often replaced, though the new one 
seldom acquires the size and strength of the 
original. This is the first time in all my experi- 
ence as a collector, that a case of this kind 
has come under my notice, though I believe simi- 
lar instances have been observed by others.—Cy-

Collecting Cychrus. 
As a rule amateur collectors think insects are 
to be found only in summer. This is a great mis- 
take as far as the Coleoptera are concerned, speci- 
mens being obtainable at all seasons of the year. 
Winter is not prolific in insect life, to be sure, 
but if you know where to look you will secure 
many desirable species rare at other seasons; this 
is especially true of the beetles living under the 
bark of trees. 
But it is in the early spring the collector 
should be active if he would secure a few species 
of Cychrus for his collection. The species of in- 
sects comprising this interesting genus are just 
rare enough to be favorites with most collectors, 
but this comes partly from the lack of knowledge 
respecting their habits. As well try to find 
Cicindelide on the surface of water as Cychrus 
in the ordinary way. With the possible excep- 
tion of Cychrus elevatus they are rarely seen under 
stones. Most species prefer to live under leaves 
as companions to the various land snails, and are 
comparatively common in early spring. 
As soon as the snow is off the more open 
ground, take your bottle of cyanide, a stick, and 
all your patience, go to some sunny side hill on 
the borders of a forest, carefully turn over the 
leaves that lie on the ground, as well as every stone 
that is partly covered with leaves, and search 
diligently for beetles. The stick is good enough
