Longicornia Malayana. 623 



duobus sequentibus fere sequali^ 6-10 extus apicem 

 versus dilatatis. Protliorax ovatus, muticus, trans- 

 verse corrugatus, dorso tuberculatus. Elytra bre- 

 viuscula, apicibus Integra, subtruncata. Pedes validi ; 

 femora clavata. Prosternum elevatum ; mesosterniim 

 simplex. Abdomen segmento prime majore. 

 The finely granulate eyes of this genus, combined with 

 the form of the antennae, will readily distinguish it from 

 all others of its group. M. Thomson by a slip of the pen, 

 says the femora are not clavate, and that the rounded 

 apex of the suture of the elytra is bispinous. In numer- 

 ous examples now before me they are as stated above. 

 In some specimens the antennae of the male are scarcely 

 so long as the body, and in the female they are only a 

 little shorter.
