the largest of the eight. Mandibles powerful, conical, vertical, with a 
few teeth and a fringe of long hairs on the inner surface. Maxillæ 
strong, curved towards the lip, enlarged at the extremity, which is 
obliquely truncated and fringed with hairs on the inner side. Lip nearly 
quadrate, rather broader at the base than the extremity. Sternum heart 
. Shaped. These parts are brownish black, the maxillæ having a tinge of 
red at the extremity, and the sternum being thinly covered with long 
black and short yellowish brown hairs. Legs and palpi dark yellowish 
brown, with black bands; the latter have a curved claw at their extre- 
mity. Fourth pair of legs the longest, then the first; third pair the 
shortest. Each tarsus is terminated by three claws; the two superior 
ones are curved and pectinated, and the inferior one is inflected near 
its base. Abdomen oviform, rather broader at the posterior than the 
anterior extremity, thickly covered with hairs, convex above, projecting 
over the base of the cephalo-thorax ; the upper side is yellowish brown, 
a band of a paler hue extending from the anterior part, along the middle, 
more than a third of its length; this band bas an obscure border of 
black, on which are several irregular white spots; a series of black and 
white spots, disposed alternately, commences near the extremity of the 
band, on each side of the medial line, and extends to the spinners, where 
the two meet; the black spots of both series are connected by obscure, 
black, angular lines, each comprising a white spot within its vertex; the 
sides are mottled with dull olive-brown, yellowish brown, and white; and 
the under part is yellowish brown. A compressed, hairy process, en- 
larged at its extremity, is connected with the anterior margin of the 
sexual organs. 
The male is smaller than the female, and paler; but it resembles her 
in the general distribution of its colours, and in the relative length of its 
legs. Base of the thigh of each anterior leg black. The first and second 
joints of the palpi are dark brown; the third and fourth, which are 
short, are yellowish brown; and the fifth is dark reddish brown; this 
last joint is of an elongated oval form, convex and hairy externally, with 
a cavity near its base, on the under side, comprising the palpal organs ;
