Endelus violaceipennis sp. nov. 
Broadly ovate, attenuate posteriorly, subconvex ; head and pro- 
notum bluish black, the latter with the anterior angles reddish, 
shining ; elytra bright violaceous ; beneath bronzy green. 
Head elongate, slightly wider posteriorly, very much narrower 
than prothorax; front narrowly, abruptly, and deeply excavated 
between the eyes, lateral sides of excavation nearly parallel, 
median line distinctly marked from vertex to middle, becoming 
obsolete in front of epistoma; eyes prominent and strongly 
angulate, with the inner side strongly margined, placed at the 
extreme lateral part of the excavation; surface very finely 
granulate, with a few larger punctures intermixed and of a 
cupreous color on the anterior part, deeply impressed in front 
of epistoma, which is elevated, narrowly and deeply emarginate, 
and with the lateral parts extending along the inner side of the 
eyes ; sides very much constricted below the antennse, which are 
nearly contiguous. Pronotum transverse, about twice as wide 
as long, widest a little behind the middle, front distinctly 
narrower than base ; sides rather strongly angulate at the poste- 
rior third, strongly rounded anteriorly, obliquely narrowed 
posteriorly to the hind angles, which are obtusely rounded ; ante- 
rior margin with a large, widely rounded, median lobe, with the 
angles rather obtuse; base bisinuate, with a large median lobe, 
truncate in front of the scutellum; disk widely, transversely 
elevated anteriorly; sides broadly flattened, basal third with a 
widely rounded, transverse concavity; surface nearly smooth, 
with a few, indistinct, sparsely placed punctures. Scutellum 
11 Endelus cornutus, described by Kerremans from Luzon, has not been 
seen by me.
