arcuate, rounding at the humeri and more gradually rounding and 

 converging behind the middle to the evenly ogival apex, the surface 

 not strongly convex at base, the punctures fine, perforate, rather 

 sparsely scattered, the points of attachment of the short hairs not 

 distinct, the surface polished, the coarse punctures scattered along 

 the finely reflexed lateral margins only moderately large, deep, the 

 surface adjoining the margin barely at all impressed; abdomen not 

 quite so strongly or densely dull as usual, the few scattered punctures 

 very fine though evident. Length 1.2 mm.; width 0.63 mm. Flor- 

 ida (Capron). [Limnichus (Limnichoderus) seriatus Csy., Ann. 

 N. Y. Acad., 1890, p. 158] seriatus Csy. 



Form more broadly oval, not quite so shining, blackish, paler and dusky- 

 rufous beneath, the short hairs rather longer and more evident; 

 prothorax similar in outline but with the very minute punctulation 

 rather more close-set; scutellum a little broader, triangular; elytra 

 about a fifth longer than wide, similar in general form to the pre- 

 ceding, the punctures more numerous, much coarser and deeper than 

 in seriatus, becoming still more notably coarse, deep and numerous 

 on the convex flanks, coarse along the fine reflexed lateral margins 

 and sublinear in arrangement throughout, the surface evidently 

 impressed along the lateral m'argin; abdomen more densely dull 

 than in seriatus, the fine and widely scattered punctures less visible. 

 Length 1.2 mm.; width 0.66 mm. Florida (locality unrecorded).

6 Outline almost regularly oval, stout, only moderately convex, black- 

 ish, dusky-rufous beneath, dull; head rather small; prothorax short 

 and strongly transverse, the very strongly converging sides nearly 

 straight, not impressed medially, the very minute punctures bearing 

 the short dense appressed pubescence close-set; elytra barely a 

 fifth longer than wide, widest near the base, the sides evenly rounded, 

 not more strongly at the humeri, gradually converging and arcuate 

 posteriorly to the ogival apex, the very dense matted pubescence 

 luteous-brown, somewhat variegated, the larger scattered punctures 

 much coarser than in any of the preceding, also coarse and sublineate 

 on the flanks, the subvertical part of which is shallower than usual; 

 abdomen with fine dense sculpture, the scattered punctures rather 

 numerous, moderately large and distinct. Length 1.5 mm.; width 

 0.8 mm. Central Texas (Belf rage). [Limnichuslutrochinusl.ee.,

Outline shorter and broader, smaller in size, more rapidly ogival behind, 

 more convex, the short pale yellowish-fulvous pubescence shorter 

 and less abundant but very conspicuous, the longer suberect hairs 

 numerous; surface more shining beneath; color blackish-castaneous, 

 dusky-rufescent beneath; prothorax as in lutrochinus but not quite 

 so broad, the fine close-set punctures distinctly larger and less 

 numerous and the short hairs shorter and less dense; elytra still 

 shorter, but little longer than wide, the sides more parallel, broadly 

 arcuate, slightly more rounding basally than in lutrochinus and rather 

 more rapidly rounding and converging from near basal third to the 

 ogival apex, the surface more shining and less pubescent in a basal
