mencing a little before the middle, at first very gradual, at about 
two-thirds their length abruptly dilated ; apex of each rounded, 
and offering a small triangular emargination ; surface finely 
setose ; disk closely punctured, and with two very fine raised 
lines, united before the apex (where alone they are distinct) ; 
dilated margins (outside the strong lateral carina) shagreened 
and traversed, to the apex, by a nearly straight carina ; colour 
black, with a basal spot on each shoulder bent towards the su- 
ture, and a broad fascia beyond the middle, fulvous ; the edges 
both of the humeral mark and the fascia irregular. Body be- 
neath and legs black ; coxae and thighs beneath pale testaceous.

rior margin, black. Elytra elongated, the dilatation commencing 
very gradually before the middle, and at two-thirds the length 
more abrupt ; at the apex singly rounded and faintly emarginated; 
surface finely setose, closely punctured, and with two indistinct 
raised lines united before the apex; dilated margins (outside the

occupying together, in some species, nearly one-half the total
