nutely punctate, scutellum black, elytra with a sliallow su- 

 tural depression below the base, extremely minutely pnnctu- 

 red, black, the apical sutural angles obscure fulvous; abdo- 

 men ilavous, the breast and legs black, claws appendiculate, 

 anterior coxal cavities closed. 



Hab. Cameroons. 



There is only a single female specimen of this species 

 before me, which is well distinguished by its coloration and 

 the very minute elytral pnnctuation, the last abdominal seg- 

 ment is nearly entire and the ab domen is clothed with ful- 

 vous pubescence. 



Vitruvia gen. n. 



Body elongate, glabrous, antennee filiform, head without 

 trontal tubercles, thorax subquadrate, convex, without sulcus, 

 elytra impunctate, their epipleurse extremely broad and con- 

 tinued to the apex, legs slender, the first joint of the poste- 

 rior tarsi as long as the following joints together, claws 

 appendiculate, prosternum invisible between the coxse, the 

 anterior cavities open. 



This genus is very closely allied to the Eastern Suma- 

 trasia Jac. (Notes Leyd. Mus. Vol. VI), it is of exactly the 

 same colour, size and shape but differs in the structure of 

 the head which is broad and flat without trontal eleva- 

 tions, the antennse are also inserted below the eyes and more 

 widely separated, the elytral epipleurre are still very much 

 wider than in Sumatrasia and the elytra itself are not punc- 

 tate-striate. Type Vitruvia glalmpennis. 



Vitruvia glabripennis sp. n. 



Plate 10. fig. 8. 



Entirely påle fulvous, the head, thorax and the elytra 

 impunctate, the legs linely pubescent. 



Length 5 — 7 mill. 



Head very broad and flat, påle fulvous or testaceous, 

 the clypeus not separated from the face, apex of the man- 

 dibles black, antennee scarcely extending to the middle of 

 the elytra, testaceous, the second, third and fourth joint gra-
