Underlaeben (Fig. 4 c) har Sidelapperne stmrkt diver- 
Serende og af en noget uregelmsessig, naesten oxedannet 
Form. 
Kindbakkerne (Fig. 4 d ) er forholdsvis svagt udvik- 
Fdr og har den mod Munden rettede Fade fint tandet, 
® eM mangier tydeligt begrsendset Tyggeknnde. Palpen er 
nit “get liden og rudimentser, skjondt bestaaende af de 3 
s *dvanli ge Led. 
Kjffiverne (Fig. 4 e—f) er ligeledes meget smaa og 
Sva o e - lste Par (Fig. 4 e) har Tyggepladen temmelig bred, 
h' oriniod Palpen er smal, najsten lineser; Basalpladen synes 
a t mangle Burster, 2det Par (Fig. 4 f) liar den indre 
Fap kortere end den ydre. 
Kjfevefedderne (Fig. 4 g) er, i Modsmtning til de ovrige 
^'uiddele, meget store, fodformige og rager frit frein neden- 
^nder Hovedet (so Fig. 4). De mangier ganske Tyggelap, 
lllen bar en liden rudimentser Basalplade. Palpen er sffir- 
'b'les stark t bygget og ender med en kraftig Klo. 
lste Fodpar (Fig. 4 h) er forholdsvis lidet og svagt 
b}gget. 3die Led forlsenger sig nedentil i en smalt til- 
j Ul 'det borstebesat Lap. Haanden er af oval Form og kun 
blet sterre end det foregaaende Led, men har, i Modsset- 
’b'lg til hvad Tilfaeldet er hos enkelte andre Alter af Sbegten, 
<>n tydeligt begrseudset skraa Griberand. 
-det Fodpar (Fig. 4 i — h) er hos begge Kjon smr- 
( b‘les kraftigt udviklet, med 3die og 4de Led korte og brede, 
u, h'idede mod Enden og nedad forlsengede i smaa bprste- 
besatte Lapper. Haanden er meget star og opsvulmet samt 
VlSer hos Hun og Han et temmelig forskjelligt Cdseende. 
Hos Hunnen (Fig. 4 i) er den af tilnarmelsesvis oval Form, 
n ( ( ‘d Griberanden noget skraa og uregelmiessigt bugtet, fint 
c dieret, samt omtrent ved Midten forsynet med et enkelt 
b°i't tandformigt Fremspring; nedentil er Griberanden be- 
§ r ®ndset af en stark, triangulaert tilspidset Fortsats, der 
bagtil gaar i Flugt med den nedre Band af Haanden. Hos 
Hannen (Fig. 4 h) viser Griberanden nedenfor den mediane 
Fund en sierdeles dyb Indbugtning eller Xndsnit, hvorved 
den nedenfor liggende Fortsats antager Formen af en sser- 
d'des stor lancetformig fremskydende Flig. 
De 0vrige Fodder er temmelig spinkle, kort borste- 
esatte og alle omtrent af ens Larngde. 5te Par (Fig. 4 /) 
ar som hos Slaagtens pvrige Alter Hofteleddet meget smalt 
^ af linear Form, hvorimod dette Led paa de 2 folgende 
‘ u ( ‘ r pladeformigt udviklet og ovalt. 3die Led paa disse 
°dpar gaar bagtil ud i et tilspidset Hjorne, dor dog paa 
a,l gt n mr ikke er saa, stmrkt fremspringende som hos M. 
-4 Ideri. 
Sidste Par Halefodder (Fig. 4 m) raekker ikke ud over 
’ 4 foregaaende Par og er som hos de ovrige til denne 
amilie horende Former simple, 3-leddede, samt koniskt 
blspklsede. Kanterne er ganske glatte, uden Torner eller 
Harster. 
Halevedhsenget (Fig. 4 n) er aflangt ovalt og i Spidsen 
Sll 'ipelt tilrundet, uden nogensomhelst Bevmbning. 
The labium (fig. 4 c) has the lateral lobes widely 
diverging, and somewhat irregular — almost securiform — in 
shape. 
The mandibles (fig. 4 d) are comparatively slight m 
development, and have the extremity directed toward the 
mouth, finely dentate, but do not exhibit a distinctly defined 
molar protuberance. The palp is very small, and rudiment- 
ary, though consisting, as usual, ol 3 articulations. 
The maxillse (fig. 4 e—f) are likewise very small and 
feeble. The 1st pair (fig. 4 e) have the masticatory lobe 
rather broad, whereas the palp is narrow, almost linear; 
the basal plate would seem to be wholly unprovided with 
bristles. The 2nd pair (fig. 4 f) have the inner lobe shorter 
than the outer. 
The maxillipeds (fig. 4 g) — contrary to what is the 
case with the other oral appendages — are very large, pedi- 
form. and jut out freely from beneath the head (fig. 4). 
The masticatory lobe is entirely wanting, but they have a 
small rudimentary basal plate. The palp is remarkably 
strong, and terminates in a powerful claw. 
The 1st pair of legs (fig. 4 h ) are comparatively small, 
and feeble in structure. The 3rd joint is produced down- 
ward to a narrowly rounded lobe. The hand occurs ol an 
oval form, but slightly exceeds the preceding joint in size; 
it has, however, contrary to what is the case in some 
species of the genus, a well-defined oblique palmar margin. 
The 2nd pair of legs (fig, 4 i—h) are m both sexes 
most powerfully developed, with the 3rd and 4th joints 
short and broad, dilated towards the extremity and produced 
downward as small, bristle-bearing lobes. The hand is very 
large and swollen, and exhibits, both in the male and female, 
a somewhat different appearance. In the female (fig. 4 *), it 
has an approximately oval form, with the palmar margin 
somewhat oblique and irregular-sinuous, finely ciliated, and 
exhibiting a single short dentiform projection; below, the 
palmar margin is defined by a strong triangular-jomted apoph- 
ysis extending posteriorly in a line with the lower margin 
of the hand. ~ In the male (fig. 4 h), the palmar margin 
exhibits below tlie median tooth a very deep sinus, or in- 
cision. whereby the apophysis jutting forth below it as- 
sumes the form of an exceedingly large, lanceolate, protrud- 
1Il! " 1 The remaining legs are comparatively slender, beset 
with short bristles, and all about equal in length. The 5th 
pair (fi°- 4 1) have the basal joint, in common with the 
other species of the genus, very narrow and linear in form, 
whereas that joint in the 2 succeeding pairs is lamelliform- 
dilated and oval. The 3rd joint of these legs juts out 
posteriorly as a sharp-pointed corner, which, however, does 
not bv far project to a like extent as in M. Alderi. 
The last pair of caudal stylets (fig. 4 m) do not reach 
beyond the 2 preceding ones, and are, as in the other forms 
belonging to this family, simple, tri-articulate, and conically 
• A . — . - . . il. oirnni 1 
pointed. The margins 
are 
quite smooth, without either

at the point, without any armature whatever.
