four-sevenths; punctures coarse and deep; foveae strong, near basal 

 and apical third. Length (9) 4.7 mm.; width 1.8 mm. Florida 

 (Lake Worth) prosperum n. sp. 



Form somewhat similar but narrower, convex, shining throughout, deep 

 black, the elytra with apex and external subapical spot feebly pallid, 

 these areas not at all well defined; under surface piceous-black, the 

 abdomen pale rufous; legs similarly rufous; head rather small, three- 

 fourths as wide as the prothorax, much narrower than an elytron, 

 the sulci narrow and rather deep; eyes not very prominent; antennae 

 slender, fuscous, pale basally, the medial joints nearly three times 

 as long as wide; prothorax small, similar in general form and surface 

 to that of prosperum, but only a fourth wider than long, widest near 

 anterior two-fifths, with the arcuate sides less arcuate and oblique 

 for a longer distance posteriorly, the base four-sevenths the maxi- 

 mum width; elytra similar but narrower, the similarly punctured 

 striae obsolete in nearly apical third; foveae near two and four sev- 

 enths. Length (cf) 4.4 mm.; width 1.6 mm. Florida (Indian 

 River), J. F. Kemp luculentum n. sp. 



Form more slender, strongly convex, very shining, deep greenish-black, 

 the head barely perceptibly alutaceous; elytra without trace of paler 

 marking, except at the sides near the apex, where there is a minute 

 and excessively feeble trace of a spot, only visible in strong light, 

 the extreme tip also very faintly paler; under surface black, the abdo- 

 men very obscure rufous, the legs testaceous; head four-fifths as 

 wide as the prothorax but not as wide as an elytron, the sulci not 

 very broad and rather deep; antennae moderately long, three-fourths 

 as long as the elytra, fusco-testaceous, the medial joints not quite 

 three times as long as wide; prothorax small, convex and polished, 

 about a third wider than long, very much narrowed at base, widest 

 but just before the middle, the sides strongly rounded to the angles, 

 not sinuate before the latter, which are minutely prominent; base 

 with a few punctures and but little more than half the maximum 

 width; impressions subobsolete, the stria very fine; foveas small, 

 deep, elongate-oval, the carina obsolete or virtually so; elytra three- 

 fifths longer than wide, oblong-oval, very gradually narrowly para- 

 bolic behind, two-fifths wider than the prothorax; striae not very 

 fine, unimpressed, obsolete near apical fourth, the punctures rather 

 strong and notably well separated ; foveae before basal and near api- 

 cal third. Length (d 71 9 ) 4.2-4.6 mm.; width 1.45-1.6 mm. New 

 Jersey (Cape May). Five specimens vividum Csy. 



60 Prothorax narrow, but little wider than an elytron, the base barely 

 perceptibly narrower than the apex. Body black, alutaceous ante- 

 riorly, the elytra very shining, with a small pale spot on each on 

 the basal declivity, a long feeble streak on the eighth interval and 

 a moderate external subapical spot, broadly united along the mar- 

 gin with the apical pale area; inflexed sides rufescent, the under sur- 

 face black, the abdomen partially dull rufous; legs very pale flavo- 

 testaceous; head small, though more than three-fourths as wide as 

 the prothorax, much narrower than an elytron, the sulci parallel, 

 rather deep; antennae fuscous, pale basally, the medial joints less
