530 EEY. O. PICKABD-CAMBfilDGE ON [Apr. 18, 



Impressions strong and abrupt, and very forward, being just in the 

 line with the anterior row of eyes. Clypeus broad, sides parallel, 

 very prominent and projecting, its anterior margin truncate, and its 

 height (or width from front to back) exceeds half that of the facial 

 space. Colour dull orange-yellow brown, bisected longitudinally 

 by a white, somew hat broken line, and with other more or less 

 distinct white lines converging to the thoracic indentation, which 

 cippears to be placed remarkably far back. 



Eyes forming a broad curved area of uniform width ; the anterior 

 row shortest, the small central pair of eyes of this row smallest 

 of the eight ; all are seated on conical whitish tubercles, those of 

 the lateral pairs much the largest and confluent. The eyes of the 

 anterior row are equally separated : the hind-centrals a little farther 

 from each other than from the hind-laterals. Lateral eyes much the 

 largest. The curve of the two rows is not great, the convexity 

 directed forwards. The central quadrangle is broader than long, 

 and its fore-side shortest. The hind-lateral eyes are separated 

 from each other by the width of the fore margin of the clypeus. 



Falces strong, prominent, conical: similar in colour to the 

 cephalothorax. 



Legs long, moderately strong, 2-1-4-3, but little difference 

 in length between 2 and 1. Spines normal, on all the joints 

 excepting the tarsi ; furnished also with numerous short, rather 

 fine hairs, especially beneath the femora of the first and second 

 pairs. Colour pale yellow-brown, more or less closely mottled 

 or marbled \vith white, mostly so on the femora. 



Pulpi short, yellow ; radial joint shorter than the cubital ; at its 

 extremity on the outer side is a not very long, strong apophysis, 

 somewhat bifid and blacldsh at its extremity ; underneath is 

 another not so strong, rather longer, a httle curved, tapering, and 

 its obtuse extremity has a corneous appearance. _ Digital joint 

 moderate in size, short-oval. Palpal organs simple, closely 

 surrounded by a strong, tapering, black spine. 



MaxilJce, labium, and stermm similar in colour to the legs, 

 furnished sparingly with bristly hairs. 



Abdomen long, narrow, almost cylindrical, very slightly tapering 

 at its posterior extremity. Colour dull luteous, thickly marked 

 with white distributed so as to give a somewhat linear, white, 

 irregularly striped appearance ; it is covered very thinly with 

 small tubercles, from each of which as from a socket issues a 

 prominent tapering, brownish, spine-like bristle. The hinder 

 extremity is produced into a small kind of articulated tapering 

 caudal prominence. Spinners short.
