MARAXES, gen. nov. 
Body oblong ; the maxillary palpi, terminal joint long and 
very feebly securiform; the mentum narrow, emarginate 
anteriorly; the head angularly explanate laterally, eyes 
semicircular in outline, invisible above; the clypeus anteriorly 
4-dentate, frontal suture invisible; the thorax transverse, 
with cavities in the anterior angle for the reception of the 
antennal club; the scutellum invisible externally; the elytra 
widest in the middle, humeral angle rectangular, but a little 
prominent; the pygidium invisible from above; the coxe,
