132. ATTUS AVOCATOR, sp. n. 



Adult male : length slightly over 11 lines. 



The cephalothorax of this small species is less high at the hinder row of eyes than in 

 Attics auspex, the hinder slope is (when looked at in profile) a little convex, as also is that of 

 the upper part of the caput, or ocular area. Its colour is yellow -brown, the ocular area being 

 the darkest ; it is thickly clothed with grey and yellowish mixed, appressecl hairs, showing, 

 however, three longitudinal stripes of white hairs, one on each side, just below the margin of 

 the upper part, and the third along the middle of the hinder slope. 



The eyes form an area considerably broader than long; the anterior row is equal in length 

 to the posterior; in other respects the eyes are like those of Attus auspex. 



The legs are rather short and moderately strong ; their relative length being 4, 1, 3, 2. 

 They are of a brownish-yellow colour, indistinctly annulated with darker brown, and the 

 extremities of the tarsi of the first pair are blackish. They are clothed with hairs, bristles, 

 and spines ; the terminal tarsal claws are long and slender, and are apparently devoid of 

 denticulations beneath ; underneath them, on each tarsus, is a compact, claw-tuft. 



The palpi are short, similar in colour to the legs, and clothed with coarse (and princi- 

 pally grey) hairs ; the radial is shorter than the cubital joint, and has a small pointed 

 apophysis at the outer extremity ; the digital joint is long but not very broad, being of a 

 somewhat oblong form ; and the palpal organs are simple and of a blackish-brown colour. 



The f alces are moderately long, not very strong, straight, perpendicular, but placed 

 considerably backwards, and of a dark yellow-brown colour. 



The muxillcR and labium are also yellow-brown, the former are pale at their extremities 

 which do not nearly meet over the latter ; the labium also has the apex of a pale hue. 



The sternum is small, oval, of a dark yellow-brown colour clothed with coarse grey 



hairs. 



The abdomen is oval, rather truncated in front. The upper side is dark brown, mottled 

 obscurely with yellowish, the margin being a little notched and bordered with white hairs, 

 a short streak along the middle of the fore part, of a dull yellowish hue, is followed to the 

 spinners by a series of short, but pretty distinct, angular bars of the same colour ; these mark- 

 ino-s are clothed with white hairs : the sides are longitudinally striated with brown, and the 

 under side is of a dull brownish yellow.
