COLEOPTERA.

elytron between the fourth and fifth striae, where it is narrowly rounded ; 
the third apical, as large as the basal one, but extending nearer to the su¬ 
ture, at the first stria, where it is obtusely rounded ; these three black spots 
are covered with a dull, black, short and thick velvet pile, here and there 
wanting, especially on the basal one at the shoulder. 
Pygulium ob3ique, somewhat longer than wide, convex posteriorly; 
densely covered with a white pile; having a small longitudinally ovate 
black spot at each side of the margin, a little beneath the base and the 
apex of elytra. 
Body beneath punctulate, densely covered with a white pile. Pectoral 
lamina glabrous, shining, deeply punctulate, the margin only being clothed 
with white hairs. 
Legs finely punctulate, black, slightly covered with a long, thin, ob¬ 
liquely arranged pile, of a silvery gray hue, showing here and there the 
ground. Anterior thighs and tibia rather thin and short, subcylindric, 
nearly of the same length, with their tarsi somewhat shorter. Intermediate 
legs having the same proportions, but their parts are a little more elongated. 
Posterior legs nearly the length of the body (If lin.), thick: thighs reaching 
the base of the terminal abdominal segment, clavate, widely subtruncate 
at the apex, deeply canaliculate inside for receiving part of the tibiae, 
edentate : tibia evidently shorter, angularly dilated towards the apex, where 
they are subtruncate; somewhat flat beneath, rounded on the upper side, 
which is obtusely ridged near the apex; interior margin and middle of the 
upper side acutely angular, sharply ridged, each terminated at the apex by 
a long spine; external angle having also a very short and thin spine : tarsi 
longer than the tibiae, about the length of the thighs: 1st joint more than 
half the total length, curved : claws denticulate at the base. 
Obs. —I have only seen one specimen of this handsome species. I 
suppose it to be a South American. I am happy in naming it after the 
learned entomologist whose liberality has endowed the science with several 
important works, and as a proof of my sincere attachment.
