basal impressions ; the elytra broader, more rounded ; and the entire body 
black (except the antennae and legs), and proportionally wider. 
Head oblong-quadrate, inflected, convex, rather densely punctate; 
front between the eyes longitudinally ridged ; black, with a slight gray 
pile. Eyes transverse, semi-lunar, lateral, leaving the front almost as wide 
as the vertex and the rostrum at its base ; pitchy. Rostrum short, evi¬ 
dently narrowed and rounded towards the apex, slightly impressed at the 
middle of the base ; deeply punctate-rugose ; black, subglabrous ; apical 
parts of the mouth ferruginous: maxillary palpi elongate, rather thick, 
pitchy black. Antennae rather short and thick, a little longer than the 
thorax, enlarged towards the tip ; 1st joint ovate-cylindric, rather long; 
2nd and 3rd together shorter than the 1st, equal, subglobose ; 4th to 10th 
transverse, gradually wider and more triangular within ; terminal longer, 
shortly ovate ; ferruginous, subglabrous. 
Thorax subconic, nearly as long as the width at the base; apex sub- 
truncate, or scarcely produced in the middle; sides nearly straight, or very 
little rounded, obliquely widened towards the posterior angles, which are 
acute ; base obliquely quadri-sinuate, produced in the middle which is bilo- 
bate ; convex; rather densely and deeply punctate-subrugose, more strongly 
at the sides; black, with the sides widely but not densely covered with an 
ashy gray pile. 
Scutellum rather large, subquadrate, divided longitudinally into two 
parts, each of them rounded at the apex, forming a moderate emargination; 
densely clothed with a long thick whitish pile. 
Elytra shortly ovate, twice the length of the thorax; base as wide as 
the latter, sinuate, rather emarginate in the middle for the reception of the 
produced part of the thorax, subangular at the side, where the shoulders 
thorax : many specimens from Lebas have not exactly the thorax “ crebre 
punctatus,” but certainly “ crebre punctato-rugosus, praesertim postice,” 
when viewed through a strong magnifier ; other specimens, from Caraccas, 
having the thorax shaped like that of Br. Batesii , wanting also the basal 
impression appearing in Lebasii, I consider as a third species, differently 
coloured, and distinct from both. I have in my collection about a dozen 
new species, from different parts of Columbia, collected by several natural¬ 
ists at different times, all of them of the same division, and closely allied 
to each other, but, when carefully observed, very distinct, as is also the case 
with our European species.
