than, the radial and cubital together, enlarging or clavate at the 
fore extremity, which ends with a small untoothed claw. 
Falces short, moderately strong, straight, subconical. 
Maile rather long, straight; broadest and rather roundly 
truncated at their extremity, and obliquely on the inner corners. 
Labiwm broader than long ; apex rounded. 
Sternum longer than broad, its edges very strongly and 
distinctly emarginate, with prominent angular chitinous points 
running (when looked at from below) beneath the margin proper, 
to and between the bases of the coxe of the third and fourth pairs 
of legs; a very narrow stripe, also of a similar chitinous kind, 
runs backwards between the posterior coxe from the hinder point 
of the sternum. 
Abdomen connected with the cephalothorax by a long cylindrical 
pedicle running into a strong circular socket, which forms part of 
a large coriaceous plate including the spiracular opening and 
enclosing the covering of the genital aperture. The abdomen is 
of an elongate or oblong-oval form, broadest and well rounded 
behind, and slightly constricted transversely at the middle; 
spinners very small, compact, and enclosed in a round sheath-like 
socket, 
ABTIUS DECOLLATUS, sp. n. (Plate LIT. fig. 1.) 
Adult female length 4 lines. 
Cephalothorax black, with a short white pubescence on the sides 
of the thorax, and the greater part of the thorax bright yellowish 
red, leaving a broad, irregular, lateral black margin. The surface 
is covered thickly with small tuberculous granulosities. 
Legs orange-yellow, the femora (excepting the anterior extre- 
mities, and a longish patch on the upperside of those of the fourth 
pair, which are reddish) being black, the genus and tibie of the 
fourth pair being also suffused with blackish. The femora are 
granulose. The spines beneath the tibie and metatarsi of the 
first and second pairs are in a longitudinal series of 3 pairs on the 
tibiz and 2 pairs on the metatarsi. 
Palpi yellow ; the humeral joints suffused with blackish. 
Falces similar in colour to the cephalothorax. 
Mazille and labium deep brown, tipped with a paler hue. 
Sternum dull orange-yellow. 
Abdomen and connecting pedicle black. On either side of the 
fore extremity of the upperside is a short, curved, orange-red 
stripe, the convexity of the curves directed outwards; at the 
posterior extremity of each stripe is a patch of white pubescence, 
with a similar transverse stripe of pubescence across the middle 
and down the sides, and several small spots of the same behind it, 
in a central row to the spinners, just above which is a tuft of 
longish white hairs; the fore extremity also of the abdomen is 
clothed thinly with white pubescence, and there is a lateral 
slightly oblique stripe of the same halfway between the con-
