574 Coleopterological Notices, VII. 



there are two large deep nude and widely separated fovese at basal third, the 

 ohlique attendant impressions large and feeble, not confluent anteriorly, also 

 a strong median carina extending from apical to basal third and a fine arcuate 

 carina at some distance above the eyes. J n<ewn« distinctly longer than the 

 head and piothorax, perfectly simple, except the basiil joint, which is cylin- 

 drical, minutely punctate, with the basal margin abruptly dilated; second 

 joint about as long as the third and but little thicker; outer thre- joints 

 gradually wider; tenth as long as wide; eleventh scarcely as long as the two 

 preceding. Prothorax about as long as wide, widest an 1 rather strongly 

 1 ounded anter orly, the sides gradually convergeut toward base, i-inuate op- 

 posite the lateral fovese which are large, deep and nude, with a portion of their 

 external margin cariniform and elevated; they are prolonged anteriorly for a 

 considerable distance in a gradually evanescent impression, but are wholly 

 isolated transversely; an acute spiniform process arises nearly midway between 

 each and the median line, which is deeply grooved throughout, except near the 

 base, where the groove becomes a feeble carina; a feeble longitudinal ridge ex- 

 tends anteriorly from each spiniform process. Elytra nearly '%, longer and % 

 wider than the prothorax, convex, the sides divergent and strongly arcuate; 

 humeral plica strong but not spiniferou^!, the discal impression large hue 

 rapidly evanescent; three basal fovese deep, nude and perforate. Abdomen 

 rapidly narrowed from base to apex, the latter very narrowly rounded; sides 

 very feebly arcuate; basal carinse fine but strong, parallel, fully % as long as 

 the segment and separated by }^ the discal width. Fygidium rather small, but 

 slightly transverse, feebly and evenly tumid, rather sparsely and subasperately 

 punctulate. Lega moderate in length, the anterior femora subcarinate along 

 the lower edge, especially near basal fourth, but not otherwise modified, the 

 anterior tarsi short and thick. Le. gth 1.75-2.0 mm. ; width 0.55-0.65 mm.

The description applies to the male only, and the female is quite 

 different, being sensibly smaller, with the eyes a little smaller and 

 less prominent, the tempora longer and distinctly convergent, 

 with the basal angles very obtuse, the antennse shorter and more 

 slender, the front unmodified and merely coarsely seabro-punctate 

 on the apical slope, the prothorax relatively narrower and not 

 wider than the head, the abdominal carinas shorter and slightly 

 more widely separated, the pygidium a little shorter and more 

 transverse, rather more tumid and with coarser elevated punctures 

 and the anterior tarsi longer and more slender. The modification 

 of the anterior femora is similar to that of the male. The last 

 ventral of the male has a large and very shallow impression, the 

 lateral limits of which are slightly tumid. Scabriceps, to which 

 the present species is allied, is larger and differs radically in the 

 structure of the front and tempora, and in having the small eleva-
