numerous strong hairs. Another fold in the epidermis, a little way 
in front of the spinners, appears to indicate also an additional aper- 
ture of the same nature. Spinners short, compact, those of the 
inferior pair strongest. This genus is allied to Anyphena. 
ARACHOSIA ANYPHENOIDES, sp.n. (Plate XXIX. fig. 2.) 
Adult female, length 33 lines. 
The colour of the cephalothoraxz (which is thinly clothed with 
short silky greyish hairs) is brownish yellow, tinged with dull 
orange. A broad central brown band runs from the eyes to the 
posterior extremity; and there is a submarginal thoracic line of a 
deeper red-brown hue. 
The eyes are seated on small black spots, the outer ones of the 
anterior row are smallest, and the interval between those of the 
hind central pair is considerably greater than that between each and 
the hind lateral next to it. The relative position of the eyes of the 
anterior row is also nearly similar, and the hind lateral (on each 
side) about equally separates the hind central and fore lateral 
eyes. 
aT he Jegs are of a clearer yellow colour than the cephalothorax, 
speckled with dark red-brown, chiefly on the fore parts and outer 
sides of the femora. The spines are long and rather slender ; 
beneath the tibize of the Ist and 2nd pairs of legs are 4 (in two 
pairs), and another pair beneath the base of the metatarsi; those on 
the 3rd and 4th pairs are more numerous and irregularly disposed. 
The scopula beneath the tarsi and metatarsi is densest on the Ist 
and 2nd pairs. ; 
The palpi are slender and moderately long, yellow, and furnished 
with numerous long spine-like bristles. Each palpus ends with a 
small curved claw. 
The mazille and sternum are similar in colour to the legs; the 
labium tinged with yellow-brown. 
The abdomen is of a dull clay-vellowish hue, clothed with short 
greyish silky hairs on the pale portions. A broad, longitudinal, cen- 
tral dark-brown band (slightly denticulate on its margins towards 
the hinder part) occupies the upperside, which has also on each 
side a narrow, lateral, somewhat broken stripe of a similar hue. The 
underside is also marked with a broad, slightly tapering, central lon- 
gitudinal brown band, on which are numerous pale strong hairs near 
the middle, over and around the central spiracular opening (men- 
tioned in the generic diagnosis). The genital aperture is rather 
large, somewhat horseshoe-shaped, and of very characteristic 
structure. 
A single example was contained in Mr. Traill’s Amazon collection.

CoLEOSOMA, g. n. 
Nearly allied to Sphecozone, Cambr., but easily distinguished by 
the more depressed caput, and especially by the formation of the
