TEAPEZIDEEA. r - 



u 



being simple and straight, the thorax finely (but distinctly) margined at the base, the 

 scutellum transverse, and the elytra closely and irregularly punctured. I am unable to 

 distinguish the sexes, although having only seen four specimens it is not possible to 

 assert we have both sexes present. The prosternal process is wide, slightly raised 

 above the plane of the front part of the prosternum, very even, and finely margined and 

 widened at the apex, the apex truncate in a straight line. The apical ventral segment is 

 slightly pubescent, scarcely punctured, blackish at the tip, and only a little acuminate. 

 The ferruginous colour with parts black mentioned in the diagnosis is amply sufficient 

 for the recognition of T. semiotina, and give this species a very Elateroid look. Three 

 of the four specimens are from Panistlahuaca. 



3. Trapezidera lateralis. 



Ca8taneo-rufa ; antennis, genibus, tibiis tarsisque nigris ; elytris extus et ad apices cserulescentibus, punctato- 

 striatis, interstitiis subrugulosis et confuse punctatis, apicibus leviter denticulatis ; capite prothoraceque 

 fere glabris. Long. 8 millim.

Head, thorax, body, and base of the legs castaneous, almost blood-red ; antennae, 

 apical half of the femora, tibia?, and tarsi black ; elytra steel-blue, with the suture and 

 usually the greater part of the disc castaneous-red. This species is very difficult to 

 place, as hitherto I have not been able very satisfactorily to distinguish the sexes. The 

 prosternum is broad and smooth, narrowly margined, with the apex truncate and gently 

 emarginate ; the femora are not much thickened, nor apparently at all roughened. 

 The only character which I can find for separating the males is, that in some specimens 

 the tarsi appear wider than in others, but not decidedly so, nor are they very hairy. 

 The apex of the elytra is faintly denticulate. The apical ventral segment is blackish at 

 its tip and sparingly pubescent. Taking the whole of its characters, I think at 

 present this curiously-coloured species had better be placed with Trapezidera cenea and 

 T. semiotina. About twenty specimens in all are before me. It is the " Languria 

 lateralis " of Salle's collection.

It is not possible to identify this or the following species from the descriptions, which 

 would apply to a great many species of Languriides ; nor is it probable that they are 

 congeneric with T. cenea. We insert them here to render the references complete, „
