side nearer the front and not so far apart, others on the side 
near the anterior and posterior angles; near the anterior mar- 
gin, on the side, is a large tubercle, and a smaller one a little 
behind and further from the side, a longitudinal channel lead- 
ing from the one to the other. Scutellum triangular and im- 
punctate. Elytra flattened, parallel, of the breadth of the 
thorax, truncated at the apex, each with two spines; their 
surface has a dull opaque ground, and is covered in the middle 
with small, scattered, shallow punctures; these become very

apex ; clothed with a fine, hoary-grey, velvety down, changing 
its reflections in different lights, Legs rather long ; the thighs 
reddish or brownish red, and feebly keeled on the inferior 
margin ; underside blackish, clothed with the same hoary pile. 
Abdomen with five abdominal segments.

been very various.

One of the smallest species of the genus, silky, and of a pale

reddish and somewhat rugose only on the posterior part. 
Eyes large, black, almost united behind, deeply emarginate 
above. Mandibles obscure. Antenne ferruginous, with the 
first article thick, rounded, the third a little longer than the

long as broad, very attenuated, margined and straight in front, 
more broadly behind, unequal, and with short transverse folds 
in the middle ; its colour is brownish black, with two longitu-

borders the silky part; the sides are rounded. Scutellum of 
an obseure ash-colour, rounded triangular. Elvtra a little 
broader than the thorax, nearly three times as long, shortl
