416 Rev. H. S. Gorham's descriptions of 



flavis, pedibus flavis tibiis anticis apice, tarsisque antlcis 

 nigris, antennis articulo ultimo albido. 

 Long. 3^ lin. 



Also nearly allied to suturalis and to the preceding, but 

 it differs in the whole upper surface being more shining ; 

 the thorax is more depressed in front and behind, and less 

 closely punctured ; there is very little trace of the median 

 line, it is also more narrowed in front and wider behind 

 the middle. The scutellum is yellow, the elytra black 

 and shining, thickly punctured. Legs very pale yellow, 

 anterior tibise black for the apical half, and tarsi of the 

 same pair black. 



Hab. — Amazon (Bates); coU. Fry. 



Platynoptera, Chevrolat. 

 Type, P. lyciformis, Chev. 



Pyticera, Spinola. 

 Type, P. Duponti, Spin. 



Only separable from Platynoptera by the ovate form of 

 the elytra. The species of this genus mimic Lampyridce^ 

 while those of the former mimic Lycidce. 



Pyticera Jiavicollis, n. sp. 



Nigro-picea, nitida, capite, pronoto, scutello, mesosterno, 

 coxisque cum trochanteribus flavis, elytrorum margine re- 

 flexo pallida. 



Long. 3 — 4 lin. 



Compared with P. Duponti, Spin,, this species is smaller, 

 and blacker in colour ; it is at once distinguished from it 

 by the absence of the pale vitta on the elytral margin. 

 The head is entirely yellow, with the exception that in one 

 specimen in Mr. Fry's and one in my own collection, the 

 crown is marked with pitchy. The yellow scutellum will 

 also serve to distinguish it.
