434 REV. O. P. CAMBRIDGE ON [Juiiel6, 



no special prominence or elevation ; it is, however, bold and full, the 

 occiput well rounded, and the clypeus impressed below the eyes, but 

 rather full and prominent near its lower margin, and exceeding con- 

 siderably in height half that of the facial space ; the colour is dark 

 black-brown, getting paler towards the margins ; the whole surface 

 (caput as well) thickly but minutely punctuose. 



The eyes are small and of nearly uniform size, disposed in two trans- 

 verse curved rows of nearly equal length, and not far from each other ; 

 the foremost row is the shortest, and the curves are directed away from 

 each other : the eyes of the hinder row are equidistant from each 

 other ; those of the fore central pair are the smallest, and contiguous 

 to each other ; those of each lateral pair are seated contiguously, and 

 slightly obliquely, on a strongish tubercle. 



The legs are of moderate length, but rather slender, and their 

 relative length appeared to be 4, 1,2,3; they are yellow, the femora 

 being reddish orange, and are furnished with short fine hairs. 



The palpi are moderate in length and strength, nearly similar in 

 colour to the legs ; the humeral joint orange, the radial and digital 

 tinged with dusky brown ; they are furnished with a few tine hairs, 

 those on the digital joint being much the longest. The humeral 

 joint is bent and unusually strong, the cubital short and strongly 

 curved in a sort of knee-joint form ; the radial is shorter than the 

 cubital, but stronger, and has its fore extremity (rather on the outer 

 side) produced into a short obtuse prominence bent a little down- 

 wards ; the hinder part is also a little produced, and there is a small 

 angular joint at the middle of its inner extremity ; the digital joint is 

 oval and rather large, being longer than the radial and cubital joints 

 together ; the palpal organs are prominent and complex, and have 

 a strongish black somewhat tortuously coiled, filiform, sharp-pointed 

 spine near their fore extremity. 



The falces are strong, moderately long, with a curved profile-line, 

 and are a little paler in colour than the cephalothorax. 



The maxillce and labium are of normal form, and similar in colour 

 to the falces. 



The sternum is heart-shaped, of a deep rich black-brown colour, 

 and its surface coarsely punctuose. 



The abdomen is short, round oval in form, very convex above, and 

 projects strongly over the base of the cephalothorax ; its upper sur- 

 face, on the middle of which four dark impressed spots form a qua- 

 drangular figure), is covered by a strong shining coriaceous epidermis 

 of a bright orange colour, covered with minute punctures and clothed 

 with a few short fine hairs ; a somewhat similar epidermis beneath 

 the fore part includes the spiracular plates, but is of a redder colour ; 

 aud there is a bold patch of the same colour in front of the spinners ; 

 the sides and remainder of the underside are yellowish, marked with 

 dusky greenish brown, arranged somewhat in obscure parallel longi- 

 tudinal lines on the sides and hinder part. 



The adult female resembles the male, except in wanting the coria- 

 ceous epidermis on the abdomen, which is of a uniform yellowish 

 colour, mottled and marked with dull greenish brown, freckled with
