Maris pars anterior cephalo-thoracis elevata transversè bipartita, 
segmento posteriori longiori obtuso, anterioris apice instructo tuberculo 
parvo conico prope cujus apicem anticè processus duo minuti sursüm 
curvati. 
Length of the female roth of an inch; length of cephalo-thorax Ar; breadth 
33; breadth of abdomen ; length of a posterior leg +; length of a leg 
of the third pair PG. 
Cephalo-thorax oval, glossy, gibbous above, with slight furrows on the sides, 
and a minute indentation in the medial line of the posterior region. Man- 
dibles conical, armed with teeth on the inner surface, and inclined towards 
the sternum, which is broad, convex and heart-shaped. These parts, with 
the lip, are brownish black. Maxillæ reddish brown. Legs red-brown, 
with the exception of the tibiz of the first and second pairs, which are 
dark brown; fourth pair rather the longest, then the first, third pair the 
shortest. Palpi dark brown. Abdomen oviform, convex above, project- 
ing over the base of the cephalo-thorax ; it is thinly covered with hairs, 
glossy, and brownish black. Sexual organs rather prominent. Plates of 
the spiracles yellow. 
The male resembles the female in colour and in the relative length of 
its legs. The fore part of the cephalo-thorax is elevated, and divided into 
two segments by a transverse groove in front; the posterior segment is 
the larger, and has a pair of eyes seated on its summit, which is obtuse 
and rounded ; the anterior segment is surmounted by a small, conical emi- 
nence, near the apex of which, in front, are two minute processes curved 
upwards; at the base of this cone, immediately below the curved pro- 
cesses, the smallest pair of eyes is situated, the two lateral pairs being 
placed on the sides of the anterior segment. The fourth joint of the palpi 
is larger than the third, and consists of three parts; one in front, which 
i broad, and round at the extremity; a smaller one underneath, of à 
similar form ; and a long, slender one on the inner side, which passes 
obliquely before the fifth joint : fifth joint somewhat oval, having a pro-
