62 MEMOIRS ON THE COLEOPTERA 



apically shaded slightly paler; head distinctly less than half as wide 

 as the prothorax; antennae moderately slender, pale but with the 

 club blackish; prothorax slightly more than twice as wide as long, the 

 converging sides rather strongly arcuate; base finely margined medi- 

 ally, the lobe broad and very feeble; scutellum subequilatero-tri- 

 angular, finely strigilate, with a fine peripheral margin abruptly 

 smooth, paralleled externally as usual by the reflexed basal stria of 

 the elytra, the latter slightly longer than wide, evenly parabolic in 

 outline, evenly and not broadly rounded at tip, covered everywhere 

 with not very fine micro-reticulation, which is not disposed in def- 

 inite lines, the impressed lines very feeble, the stria distinct, coarsely 

 impressed posteriorly; punctures of the series everywhere very 

 minute, though more visible than in the preceding; metasternal 

 process broad. Male with a small, narrow and rather deep sinus at 

 the abdominal apex, filled with thinner integument as usual, the 

 third segment simple; copulatory spicule slender, simple at the gradu- 

 ally acuminate apex, its lower surface strongly keeled basally. 

 Length 1.28 mm.; width 0.78 mm. Florida (Sand Point), 

 Schwarz fidelis n. sp. 



Body still smaller and narrower, shining, piceous-black, gradually slightly 

 pallescent posteriorly, the under surface ferruginous; head rather 

 more than half as wide as the prothorax; antennae slender and of 

 normal structure; prothorax twice as wide as long, the converging 

 sides evenly arcuate, the surface covered throughout, except apically, 

 with fine and feeble wavy strigiliform reticulation; scutellum as in 

 the preceding but with finer and more irregular reticulation; elytra 

 distinctly longer than wide, slightly more than twice as long as the 

 prothorax, the sides moderately converging and but feebly arcuate 

 from the base, broadly obtuse at apex; surface throughout with fine 

 and feeble micro-reticulation in tolerably distinct transverse wavy 

 lines, the impressed lines obsolescent, the stria coarsely impressed but 

 not extending before the middle; punctures of the series extremely 

 minute; prosternal process declivous and not setose at tip; metasternal 

 process unusually wide, the mesosternum before it well developed as 

 usual. Male with a large and broadly rounded sinus-like apical ven- 

 tral depression, the floor of which is thin and almost impunctate. 

 Length 1.2 mm.; width 0.65 mm. Florida (Enterprise).

17 Form oblong-oval, obtuse behind, dark piceous to blackish in color, 

 not paler apically, the under surface and legs pale; head somewhat 

 more than half as wide as the prothorax, nearly smooth; antennae 

 rather stouter but not much shorter than usual, the club slightly 

 more dilated; prothorax distinctly more than twice as wide as long, 

 the converging sides strongly arcuate; surface in great part minutely 

 and extremely obsoletely micro-reticulate; elytra slightly longer than 

 wide, between two and three times as long as the prothorax, very 

 obtusely rounded at tip, covered with a fine and transversely strigili- 

 form micro-reticulation, the punctures very minute though obvious, 

 the stria coarsely impressed, generally continued basally by a series of 

 small punctures; prosternal process of the usual form, with a fringe
