mandibulis maxillis labio sterno palpisque flavescenti-brunneis ; pedibus 
gracilibus flavescenti-brunneis nigro-fasciatis ; abdomine sordidè luteo, 
fascia nigra medianà in anteriori parte anticè triangulari postice subra- 
mosá, in series duas macularum parvarum ante filatoria coalitarum desi- 
nente. 
Maris pedes anteriores posterioribus longiores. 
Length of the female Toth of an inch; length of cephalo-thorax n; breadth 
ga; breadth of abdomen ; length of an anterior leg $5; length of a 
leg of the third pair +. 
Anterior part of the cephalo-thorax compressed ; sides depressed and marked 
with furrows diverging from the upper part to the margins ; in the medial 
line of the posterior region there is an indentation; colour yellowish 
brown, with blackish margins, a longitudinal row of small black spots on 
each side, and a black mark ofa triangular form, whose vertex is directed 
backwards, immediately behind the eyes, which are seated on black spots. 
Mandibles long, powerful, divergent at the extremity, armed with a few 
teeth on the inner surface, and inclined towards the sternum, which is 
broad and heart-shaped. These parts, with the maxillæ, lip and palpi, 
are yellowish brown, the sternum and lip being the darkest. Legs slen- 
der, of a yellowish brown colour, with black bands; first and fourth pairs 
the longest and equal in length, third pair the shortest. Abdomen ovi- 
form, thinly covered with hairs, very convex above, projecting over the 
base of the cephalo-thorax ; it is of a dull yellow colour, with a black 
band in the medial line of the upper part, extending from before rather 
more than a third of its length; the anterior portion of the band is tri- 
angular, with its vertex directed forwards; the posterior part is narrower 
and somewhat ramified ; from the termination of the band extends a lon- 
gitudinal row of irregular black spots, on each side of the medial line; a 
few of these spots unite immediately above the spinners, and form there 
short, curved, transverse lines; numerous streaks and patches of black 
occur on the sides, the largest of which are on their anterior part; the 
under part, and the plates of the spiracles, are dull yellowish brown. = he 
sexual organs are prominent, and havea curved process in connection
