312 Mr. F. P. Pascoe on some new Genera of 



next together. First abdominal segment not twice as long as 

 the second. 



The type of this genus has long been known as the Obrium 

 fuscatum of Dejean^s Catalogue ; but, if we except the elytra and 

 legs, all the above characters are at variance with that genus*. 

 I may add that the maxillary palpi are very short compared to 

 those of Obrium, the second and third joints especially so. 



Ossibia fuscata, 

 O. fuscescens, elytris viridi-piceis, sutura testacea. 



Hab. Senegal. 



Pale brownish, thinly pubescent, with scattered stiffish hairs ; 

 head brownish red ; eyes black ; prothorax vaguely punctured, 

 a little tuberculate on each side at about the middle ; scutellum 

 small; elytra covered with shallow scattered punctures, the 

 suture testaceous, the sides pitchy, with a greenish tinge ; body 

 beneath and femora reddish testaceous ; tibiae, tarsi, and antennae 

 brown. Length 4 lines. 



NiDA. 



Antennne art. quarto quam tertio vel quinto breviore. 

 Prothorax elongatus, subcylindricus. 

 Mesothorax elongatus, mesosterno angustato. 



Head short in front. Eyes moderate. Antennae longer than 

 the body, the fourth joint shorter than either the preceding or 

 following one. Prothorax elongate, subcylindrical. Elytra 

 narrow, nearly parallel at the sides. Legs scarcely elongate, the 

 femora strongly clavate. Mesosternum narrow ; mesothorax 

 elongate. 



The principal characters differentiating this genus from Rho- 

 palophora are the greater length of the mesothorax (by which 

 the intermediate legs are placed at a considerable distance from 

 the anterior pair), the narrowness of the mesosternum, and the 

 nearly cylindrical prothorax. The habitat of the genus is ex- 

 ceptional, all the Rhopalophorce and their allies being natives of 

 the New World, with the probable exception of CleomeneSj 

 J.Thomson. 



Nida flavovittata. 

 N. nigra, elytris vittis duabus flavis omatis. 



Hab. Pegu. 



Black; head clothed with longish, white, scattered hairs; pro- 

 thorax closely, and even confluently punctured, a few whitish 

 hairs on the disk, with a somewhat semilunar or C-formed white
