a spyglass. The club joints are ovate, flat at the base ; the 

 last is large and obtusely acuminated. I consider the princi- 

 pal distinguishing character to lie in the remarkable structure 

 of joints 7-9 of the antennae. The maxill. palpi have joint 

 2 rather strongly incrassated at the apex, joint 3 obovate, 

 narrowed at the base, joint 4 very minute, truncated at the 

 apex. The mandibles are furnished with a bifid tooth and 

 are strongly and abruptly dilated at the base. The thorax is 

 of an obovate or obcardato-ovate form, being rather strongly 

 rounded off before the middle and gradually narrowed below 

 it; the usual basal impressions are wanting, the posterior 

 margin has two slight sinuosities, the posterior angles are 

 rounded off or obliquely truncated. Scutellum obsolete. 

 Elytra furnished with a very short elevated ridge at the 

 shoulder. Legs elongated ; coxae large, the two posterior ones 

 rather distant from each other ; two posterior trochanters much 

 elongated, incrassated at the tip ; apex of tibiae subcylindric, 

 but not narrowed, and hairy, especially in the 2nd pair; 

 joints 2-3 of the tarsi of equal size, the first longer, the 4th a 

 little shorter ; two anterior tarsi slightly contracted, 2nd and 

 3rd pair more and more elongated. Penultimate segment of 

 abdomen with strong longitudinal groove on the back.

Of the general appearance of the former, but of a light 

 yellowish colour, and well distinguished by the large thorax, 

 truncated elytra, and abnormal construction of the 2 posterior 

 femora. Antennae with joints 7-8 rather strongly obliquely 

 truncated at the apex, 9-11 forming a club, subglobose, flat 

 at the base, the last acuminated and slightly cut away or 

 even excavated on the inside of the apex. Last joint of
