very convex on the under surface, and thei'e closely and 

 distinctly punctured. The legs arc pale yellow, the 

 femora pitchy on their hind margin ; the hind tarsi long 

 and slender; their hasal joint, though not quite so long as 

 the other four together, is longer than the three following 

 taken together. 



In the male the second segment of the hind body has 

 on the upper side three long spines, reaching about to the 

 extremity of the next segment, the middle one not quite 

 so long as the side ones ; the third segment has its hind 

 margin a little emarginatc ; the sixth segment has an ele- 

 vation near each side extending from the base to the 

 extremity, between these it is a little impressed, and 

 immediately in front of the hind margin is furnished with 

 four or five small asperities ; the seventh segment is 

 covered above with similar asperities, and is longitudinally 

 elevated or swollen in the middle. 



Ega ; one male.

The single specimen before me of this species is clearly 

 immature, so that I shall not give details of its colouring 

 fiu'ther than to say, that it is of a ])itchy colour, with the 

 basal ])ortion of the antenna? and the legs (more particu- 

 larly the femora) paler. Antenna? with the 3rd joint 

 about twice as long as the 2nd, and one and a-half times 

 the length of the 4th ; 5th much shorter than the 4th, 

 longer than broad; 6 — 10 diftoring but little in length; 

 the 10th scarcely so long as broad; last joint pointed, 

 about twice as long as the 10th. The head is closely 

 and rather coarsely punctured, with a smooth sliining 

 space in the middle. The thorax is about as long as 

 broad, with a distinct longitudinal channel ; scarcely nai'- 

 rowed behind ; the sides nearly straight i'rom the front 

 to the hind angles ; it is moderately finely and very 

 closely pvmctm-ed, so that it is not at all shining. The 

 elytra are about as long as the thorax and one and a-half 

 times its width, their punctuation extremely close, and 

 finer than that of the thorax, quite dull. The hind body 

 is shining above, and obsoletely but distinctly punctured.
