About the width of a moderate sized Anth. albinus, L., but much 
shorter, very convex. Nearly allied in form to Brachytarsus areolatus and 
scabrosus, and to Phcenithon semigriseus, Grin, and implicatus, Sell., &c., 
but much larger and more convex than the former, and different in the 
antennae and thorax from the latter. 
Head short, transverse, nearly one half narrower than the thorax at the 
base, immersed in the latter up to the eyes; vertex convex, clothed with a 
pitchy black pile, which forms three triangles on the forehead, of which the 
middle one is the longest and widest ; front flat, nearly half the total 
width with the eyes, having an obsolete short longitudinal impression in 
the middle, densely covered (as well as the rostrum) with a whitish gray 
pile. Eyes finely reticulate, black, less convex, occupying together a little 
more than half the total width. Rostrum shorter than the head, and, like 
the latter, finely punctulate. Antennce very short, reaching a little beyond 
the base of the thorax, black, with the club black tomentose. 
Thorax transverse, more than one-half shorter than the basal width ; 
base scarcely sinuate, a little produced in the middle ; posterior angles ob¬ 
tuse ; sides obliquely and very shortly dilated to the angles of the posterior 
carina, then roundly narrowed towards the apex, which is obliquely trun¬ 
cate, and nearly twice narrower than the base; posterior carina ap-
