Coleopterological Notices, IV. 603 



Tiles beneath ; on the upper surface the scales are jjale and dark brown, the 

 former forming three vittse on the pronotum and densely clothing intervals 

 tliree, five and seven, the line of the third and seventh uniting near the apex 

 and continuing thence as a single short line to the apical angle ; other inter- 

 vals having very narrow inconspicuous lines composed of more slender, whitish 

 and brown squamules. Head densely punctate and squamulose anteriorly, 

 the base of the beak bristling with erect scales, the beak slender, smooth, 

 polished, rather coarsely but not densely lineato-punctate, strongly, evenly 

 arcuate and a little longer than the head and prothorax, the basal joint of the 

 funicle as long as the next three, the club small but robust, oval, densely 

 pubescent, scarcely as long as the preceding four joints combined, with the 

 basal joint composing nearly three-fifths of the mass, the remaining rings 

 short but very distinct. Prothorax two fifths wider than long, the sides sub- 

 parallel and feebly arcuate in basal two-thirds, then rounded, strongly con- 

 vergent and broadly constricted to the apex, which is about one-half as wide 

 as the base, the latter transverse and perfectly straight, the median lobe small 

 but abrupt, prominent ; disk very densely but not coarsely punctate. Elytra 

 but slightly wider than the prothorax and fully twice as long, hemi elliptical, 

 the humeri scarcely at all prominent ; disk deeply, not very coarsely striate, 

 the intervals flat, from two to three times as wide as the grooves, moderately 

 densely, deeply but not coarsely punctate. Under surface extremely densely 

 punctate throughout. Prosternum deeply, longitudinally impressed, squa- 

 mose, separating the coxae by not quite one-half of their own width. Length 

 3.0 mm. ; width 1.35 mm. 



Maryland. 



A single female. I have, however, seen another specimen in the 

 cabinet of Mr. Jiilicb. This is a very distinct form, easily distin- 

 guishable from helvinus by its larger size, more transverse and tri- 

 vittate prothorax, and by the alternately conspicuously squamose 

 elytral intervals. It closely resembles a small Limnoharis grisea. 



I.I1^0]*0TIJS n. gen. 



This genus is founded upon a male representative in the LeConte 

 cabinet, which cannot be distinguished in any way from Boheman's 

 Ceyitriniis distinctus, as described from Brazil ; it will include also 

 the Brazilian C. ivestwoodi, parallelus and other allied species. 



The body is stout, rhomboidal and convex, the beak long, more 

 or less slender, arcuate and slightly gibbous above at base, the con- 

 . striction separating it from the head being in the form of a deep 

 transverse and extremely pronounced furrow. The mandibles are 

 large, prominent, non-decussate and strongly dentellate along their 

 inner edge. Antenna? inserted behind the middle, slender, the basal 

 joint of the funicle long and equal to the next three together, the
