or Slsegten characteristiske Form, idet Forkroppen er texn- 
nie % stssrkt opsvulmet med bred og lmelvet Ryg, niedens 
Dagkroppen er stmrkere sammentrykt og liar Segmenterne 
s ^ ar pt begraendsede ved bemairkelige Inds noringer. 
Integumenterne er meget tynde og gjennenisigtige, 
u den nogen tydelig Sculptur. 
Hovedet er oventil jevnt hvselvet og gaar fortil, over 
^°den af' lste Par Folere, ud i en liden, noget fladtrykt 
Dortsats, der svarer til den bos de ovrige Arter stserkt op- 
sv idniede Pandedel, hvorefter Slmgten bar faaet Navn. 
De 4 forreste Par Epimerer er meget store og brede, 
Med de nedre Kanter bredt afrundede og tmt bprstebesatte. 
4de Par er noget bredere end de ovrige, men ikke saa 
hoit. 5te Par er tydeligt 2-lappet; de 2 sidste Par meget 
smaa.

Remarks. — From the other known species, this form 
may be easily recognized by the remarkably small and non- 
inspissated frontal projection, the absence of eves,, and the 
prodigious development characterizing the 2 anterior pairs 
of legs. 
Description. — The body (see PI. XIV, fig. 4) ex- 
hibits the form peculiar to the genus, its anterior division 
being very considerably intiunescent, with the back broad 
and arching, while the posterior is much compressed and 
has the segments sharply defined by distinct instricfions. 
The integuments are exceedingly thin, and translucent, 
without any obvious sculpturing. 
The head is uniformly arched above, and juts out, 
above the bases of the 1st pair of antennae, as a small, 
somewhat depressed projection, corresponding to the prom- 
inently in tumescent frontal part in the other species, from 
which the name of the genus is derived. 
The 4 anterior pairs of epiraera are very large and 
broad, with the lower margins broadly rounded and thickly 
beset with bristles. The 4th pair are somewhat broader 
than the rest, but not so high. The 5th pair are distinctly 
bilobular ; the 2 last pairs exceedingly small. 
The lateral plates of the 3rd abdominal segment are 
evenly rounded posteriorly, and below densely beset with 
bristles. 
No frace of eyes. 
Tbs 1st pair of antennae are exceedingly small, but 
very little longer than the head, and project scarcely at 
all beyond the penultimate articulation of the peduncle on 
the 2nd pair. The basal joint is densely beset with bristles, 
tapers somewhat toward the extremity, and extends fai 
beyond the frontal projection. The 2nd articulation about 
e C , u al in length, but much more slender, cylindric; the 3rd 
articulation very small. The flagellum is considerably shorter 
than the peduncle, and composed of about 8 articulations. 
The 2nd pair of antennae are far more powerful in 
structure and upwards of twice the length of the 1st pair. 
The 2 last joints of the peduncle, and in particular the 
penultimate, are robust in structure, and thickly beset with 
bristles. The flagellum is slender and elongate. 
The 2 anterior pairs of legs are most powerfully de- 
veloped, and respectively somewhat different in form. 
The 1st pair are remarkably elongate, with the basal 
joint very large and furnished with powerful muscles, the 
3 succeeding joints, on the other hand, exceedingly short, and 
the 4th articulation, or carpus, simple, without any dilatation 
below. The hand attains a. truly remarkable length, being 
more than 4 times as long as broad, and is somewhat di- 
lated toward the extremity. The palmar margin is slightly 
arcuate, and posteriorly defined by an obtuse projection, 
from which springs a strong spine. 
The 2nd pair are considerably shorter than the 1st, 
with the 4th articulation running out below, as a slender, 
anteriorly directed, and, along one of the margins, bristle- 
beset lobe. The hand is somewhat broader, but shorter
