COLEOPTERA. 
143 
length, transverse ; sides slightly rounded, margined, apex sinuately trun¬ 
cate and slightly emarginate in the middle ; flat, black, clothed with 
a yellow pile, which becomes white towards the tip. Antennal groove 
oblong-subtriangular, perpendicular, placed under the upper margin, its 
anterior and posterior borders very near to the apex and the eyes, from 
being rather ample and the rostrum short. Labrum roundly exserted and 
raised in the middle, rufous. Mandibles exserted, ample, incurved, pitchy. 
Antennae not reaching the base of the thorax; club ample, oblong, nearly 
as long as the funiculus ; pitchy or dark rufous, with the club darker, 
tomentose. 
Thorax subconic, nearly as long as broad (length | lin.); base slightly 
sinuated; posterior carina not far from the base, and following its outline 
nearly straight, roundly dilating the sides, running a little obliquely 
upwards beneath, terminating at one-third of the length ; sides shortly and 
obliquely dilated from the base to the side of the posterior carina, there 
evidently wider than the base of the elytra, then obliquely and straightly 
narrowed towards the apex, which is one-third narrower; apex truncate, 
with its middle scarcely emarginate; somewhat convex, covered with 
a brown pile; upper surface adorned with three yellowish fulvous longitu¬ 
dinal lines; 1st, one on the middle of the disc, attenuated towards the 
apex, which it does not reach ; 2nd, one on each side of this, not far 
from the side, not following exactly its obliqueness, being more distant 
from it at the base, joining at the apex the outline of the head, rather 
broad, under side covered with a grayish yellow pile (leaving between its 
lateral margin and the lateral discoidal line a wide fuscous band), inter¬ 
rupted near its lateral border by a fuscous oblique line, abbreviated at the 
base and apex. 
Scutellum triangular, rather large, densely clothed with whitish pile. 
Elytra rather short, somewhat narrower at the base than the thorax, 
only one-half longer than the latter and their own breadth (length 1§ lin.); 
base truncate, margined, especially at the middle, where the margin 
is broader and raised ; shoulders subangular, callose ; sides slightly dilated 
to two-thirds of the length, then moderately narrowed towards the apex, 
which is obtusely rounded on each elytron with the sutural angle obtuse ; 
inflexed margin widely and shortly rounded behind the base, emarginate 
at the middle, rather convex transversely, but slightly longitudinally from 
the base to two-thirds of the length, though not at all depressed ; suture 
subelevated, especially behind, with the 1st stria deep, although thin
