232 MEMOIRS ON THE COLEOPTERA 



at the apex of the angles with the apical marginal stria as usual; 

 surface very smooth, finely punctate laterally and with a medially 

 interrupted basal line of fine punctures, the ante-scutellar fovea 

 large but shallow; elytra with evenly rounded sides, moderately 

 narrowed apically, the striae coarse, crenulate, the fifth and sutural 

 ending at basal two-fifths and third respectively, the former repre- 

 sented at base by a puncture; apical outer subhumeral half as long 

 as the elytra and strong, the marginal stria deep and abrupt, sub- 

 entire; mesosternum with the marginal stria fine, not flexed back- 

 ward at the sides, the discal stria transversely and feebly arcuate, 

 entire, abruptly flexed posteriorly, oblique and straight at each side; 

 propygidium with notably fine and moderately sparse punctures; 

 anterior tibial spinules numerous and rather long. Length 1.8-2.4 

 mm.; width 1.25-1.6 mm. Texas (Brownsville) , Wickham. Six 

 examples atrolucens n. sp. 



Body evenly but less broadly oblong-oval, convex and very smooth, 

 piceo-rufous, the prothorax and pygidia usually clearer rufous, the 

 legs pale; head only obsoletely concave, with the supra-orbital striae 

 obliquely converging anteriorly, rather approximate on the front; 

 prothorax two-thirds wider than long, smooth, with minute scattered 

 punctures sublaterally, becoming obsolete basally, the basal margin 

 with a line of fine punctures which are obsolete medially, the fovea 

 rounded, distinct; converging sides feebly arcuate, more so anteriorly; 

 lateral stria wholly wanting, the fine marginal as in the preceding 

 species and simplex; elytra much shorter than wide, very smooth, 

 the four entire discal striae strongly impressed, not crenulate, the 

 fifth and sutural ending abruptly at about basal third, the former 

 represented at base by a feeble puncture, the fourth not hooked at 

 base; outer subhumeral short, apical and extremely fine; pro- 

 pygidium finely, rather sparsely punctate; prosternal striae parallel 

 and unusually approximate, rapidly diverging toward the base which 

 is not transversely beaded; both mesosternal striae entire and 

 crenate; anterior tibiae pluridenticulate. Length 1.8-2.25 mm.; 

 width 1.28-1.4 mm. Alabama (Mobile) and Florida (Pensacola). 

 Five examples mobilensis n. sp. 



8 Outline rather evenly elongate-oval, moderately convex, very smooth 

 and shining, black, with rufous legs, the elytra finely pallescent 

 along the apical margin; head very smooth, broadly concave anteri- 

 orly, the strongly arcuate striae along the eyes not curved inward 

 anteriorly; prothorax only two-thirds wider than long, the con- 

 verging sides distinctly more rounded apically, the lateral stria 

 curving inward at apex but not joining the apical marginal stria; 

 surface smooth, the scattered lateral punctures unusually distinct; 

 at the middle of the base there is a transverse punctulate area, the 

 fovea feeble; elytra with evenly rounded sides, the striae moderate 

 and nearly smooth, the fifth and sutural wanting in basal two-fifths, 

 the fifth represented at base by a feeble puncture, the outer sub- 

 humeral fine in almost apical half, the stria of the inflexed sides 

 feeble; mesosternal striae nearly as in atrolucens; anterior tibial 

 spines fine; the propygidium is finely, feebly and sparsely punctate.
