412 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [June 2, 



The eyes are all on black spots, in two transverse rows, slightly 

 and equally curved away from each other, and occupying the entire 

 width of the caput ; they are of moderate size and not greatly un- 

 equal, those of the fore central pair being the largest ; these are 

 seated on slight tubercles, and separated from each other by an eye's 

 diameter, being also nearer together than each is to the fore lateral 

 on its side ; those of the hind central pair are separated by very 

 nearly two eyes' diameters ; they form a line a little longer than that 

 formed by the fore central pair, and are rather nearer together than 

 each is to the nearest hind lateral eye ; the eyes of each lateral pair are 

 seated obliquely on a slight tubercle and are nearly contiguous to 

 each other. 



The legs are very long, slender, sparingly furnished with hairs, and 

 armed with a few long sessile spines ; but most of these had been 

 broken off in the only example examined; their relative length is 1, 

 4, 2, 3, those of the first pair being considerably the longest ; each 

 tarsus ends with two curved claws, beneath which is a small compact 

 tuft of hairs or scopula. 



The palpi are moderately long, but slender ; the radial joint is 

 cylindrical, and nearly of equal size throughout ; if any thing, it 

 rather exceeds in length double that of the cubital joint ; and its fore 

 extremity on the outer side is produced into a small, tapering, blunt- 

 ish-pointed, curved apophysis. The digital joint is long and narrow, 

 about equal in length to the radial joint ; it is oval behind, constricted 

 over the middle, whence it continues to the extremity in a nearly 

 cylindrical form, being slightly enlarged towards the end, and the 

 point obtusely subcorneal ; the hinder extremity is produced back- 

 wards into a sharp-pointed, somewhat corneous apophysis peculiar to 

 all males of this genus ; this apophysis is rather sharply bent at its 

 base, and its length is about one fourth of that of the digital joint ; 

 the fore half of the digital joint is pretty thickly clothed with shortish 

 hairs. The palpal organs are simple, but rather prominent, and occupy 

 the hinder half of the underside of the digital joint ; these organs 

 consist chiefly of a nearly circular corneous lobe, with a pale promi- 

 nence at the fore extremity, and a black, tapering, sharp-pointed 

 spine which, issuing from their outer side, curves round their hinder 

 extremity and terminates in close contact with their inner side. 



The falees are subcorneal, straight, but projecting, moderately 

 long, not very strong, a little prominent near their base in front, and 

 furnished with bristly hairs near their extremities, chiefly on the 

 inner sides and about the insertion of the fangs. 



The maxillce are normal ; the labium, oblong, emarginate at its 

 apex, and more than half the length of the maxilla?. 



The abdomen is elongate- oval, more convex at the fore extremity, 

 where it projects over the base of the cephalothorax, than behind, 

 and falling off gradually (when looked at in profile) to the spinners ; 

 it is of a pale luteous yellow colour, marked above and on the sides 

 with tracings of small whitish cretaceous atoms ; the spinners of the 

 superior pair are tapering, 2-jointed, slenderer than the inferior pair, 

 but double their length.
