 antenuis flavis, artic^^lis basalibus tribus jiiceis (articulis lOmo 

 llmoque fractis) ; thorace Isevi, disco bifoveolato; scutello elytrisque

Hah. Teapa ? Collected by M. Pilate. 



Vertex smooth ; ft-ont impressed above the encarpae with a deep 

 fovea ; encarpae subtrigonate, thickened ; antennae filiform, the 

 third joint twice the length of the second. Thorax one-half as 

 broad again as long ; sides straight, very slightly converging at the 

 apex; disk smooth, minutely punctured. Elytra narrowly oblong, 

 slightly but regularly dilated towards the apex, the latter con- 

 jointly and regularly rounded ; surface sparingly clothed with stiff 

 suberect yellow hah's, each elytron with six moderately raised 

 vittae, their interspaces strongly punctured, elevate-reticulate, the 

 reticulations anastomosing with the vittse and rendering the latter 

 less distinct.

 Elongata, nigra, nitida, pedibus, antennis (articulis 6, 7, 8 — 11 

 exceptis) elytrisque flavis ; thorace quam longo vix latiori, disco

 utrisque tricostatis, costis duabus externis basi coeuntibus ; tarsis

 in fi-ont of the scutellum. Elytra narrowly oblong, convex, very 

 finely seriate-punctate; each elytron with three elevated vittae, the
