entire; disk with distinct lateral carinae, which are sinuate, strongly- 

 elevated, and extending from humeral angles to near the apex, a 

 broad, deep depression on each side behind the humeral angles, and 

 with broad, moderately deep, transverse basal depressions; surface 

 finely, sparsely, irregularly punctate, with a few coarser punctures 

 forming more or less distinct roAvs in basal region, the intervals aluta- 

 ceous, and each elytron ornamented with pubescent designs as fol- 

 lows: A single row of brownish yellow hairs extending from basal 

 lobe to near middle, a shorter row between it and the humerus, a 

 broad, irregular fascia at middle, composed of sparsely placed pale 

 yellow and brownish yellow hairs intermixed, with a few small in- 

 distinct spots of white hairs anteriorly, a similar fascia covering the 

 apical fourth, with a more distinct white pubescent spot anteriorly 

 near sutural margin, a few scattered hairs of the same color in the 

 humeral region, and between the median and apical fasciae the sur- 

 face is sparsely clothed with inconspicuous, semierect dark brown 

 hairs. 



Abdomen beneath sparsely ocellate-punctate, the punctures large, 

 distinct, oblong, open posteriorly, and from each puncture arises a 

 long, recumbent white hair; intervals densely, obsoletely reticulate: 

 last segment broadly, obtusely rounded at apex, with the margin en- 

 tire, and the apical gi'oove deep and following the outline of the 

 posterior margin. 



Length, 3 mm.; width, 1.25 mm.

Type.—Q,^t. No. 41614, U.S.N.M. 



Described from a unique male collected on an unknown bush at the 

 type locality, December 15, 1824, by Ferd. Nevermann. 



This species resembles oimatus Fisher, but in that species the front 

 of the head is not densely clothed with long silvery white pubes- 

 cence, the surface above is piceous and more strongly shining, and the 

 white pubescence on the elytra forms distinct designs, whereas in 

 nevermanni it simply forms a few inconspicuous spots.
