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 Anypheena. 



Arachosia anyph^noides, sp. n. (Plate XXIX. fig. 2.) 



Adult female, length 3| lines. 



The colour of the cephalothorax (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 centrjil 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. 



The legs 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 tibiae of the 1st 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 1st 

 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 maxillce and sternum are similar in colour to the legs ; the 

 labium tinged with yellow-brown. 



The abdomen is of a dull clay-yellowish 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
