flexed inward for a short distance at the apical angles, and, along the 

 base, forms a margin which becomes very feelile or obsolete along the 

 broad median lobe. The only species in which sexual characters are 

 noticeable is i//ipressus, and here the male has a very minute shallow 

 fovea, accompanied by a tuft of loose longer hairs, at each side of the 

 median line and near the middle of the length of abdominal segments 

 two, three and four. ,ji

The body in this genus is smaller and relatively shorter than in 

 Lobcnis, and has a markedly different general habitus. The lateral 

 edges of the prothorax are very finely double, the outer edge more or 

 less distinctly and unevenly undulated, the border flexed inward for a 

 short distance at apex, and, at base, as far as the fovea;, where the 

 margin becomes \ery fine along the basal lobe. There is a fine super- 

 ciliary ridge as in Loberus, but the antennce differ in having the basal 

 joint of the club about as large as the second. I have not noticed 

 any distinctive sexual characters in the male. The three following 

 are the only species known to me at present : — 



Body subglabrous, the head and pronotum clothed sparsely with very short subdecum- 

 bent hairs, the elytra glabrous, each with three discal and one marginal series of 

 very widely spaced erect setre ; sides of the prothorax very obsoletely undu- 

 lated 2 



Body clothed throughout with coarse, sparse, subdecumbent hairs in addition to the 

 series of elytral setx ; sides of the prothorax more strongly and quite distinctly 

 undulated 3 



2 — Body rather narrowly oval, convex, polished, the anterior part feebly alutaceous, 

 flavo-testaceous to blackish throughout, the elytra broadly, suffusedly paler toward 

 the humeri and in a transverse band interrupted at the suture, near apical third ; 

 antennae but little longer than the head and prothorax, the club well developed ; 

 head and pronotum finely but strongly, rather closely punctured, the punctures 

 finer toward the sides of the latter, which is three-fifths to two-thirds wider than 

 long and much narrower than the elytra, with the sides parallel and arcuate and 

 the apex very nearly as wide as the base ; elytra two and two-thirds to three 

 times as long as the prothorax, subinflated and widest at two-fifths, gradually 

 narrowed to the acute apex, the humeri feebly denticulate externally and ob- 

 liquely exposed at base ; erect setre, moderately long and distinct, the punctures 

 fine and sparse, with series of rounded areolce shining through the translucent 

 chitin from the under surface. Length I.25-I.6 mm.; width 0.65-0.72 mm.

Body and antennce nearly similar to the preceding, the former rather shorter and less 

 acute behind, pale flavo-testaceous in color, the head and pronotum more aluta- 

 ceous, the elytra polished and almost similarly maculate, with the erect seta; very
