latter, "which is blackish ; pubescence very short, decumbent and 

 somewhat dense, the coarse suberect hairs sparser. Head trans- 

 verse, convex, rather coarsely, deeply but sparsely punctate, the 

 median line impunctate ; eyes moderate, separated by fully twice 

 their own width ; antennae two-fifths as long as the body, the 

 basal joint moderately long and thicker than the second, third 

 very narrow, three to ten gradually and very distinctly increas- 

 ing in width, eleventh abruptly much thicker than the preceding 

 and rather longer than the ninth and tenth together. Prothorax 

 transverse, the sides feebl^^ divergent from base to apex and 

 nearly straight ; apex broadly arcuate; disk evenly convex, some- 

 what finely but deepl}', moderately densel}^ punctate. Elytra 

 three-fourths longer than wide, about three-fourths wider than 

 the prothorax, parallel and very feebly arcuate at the sides ; apex 

 evenl}?-, circularly rounded ; humeri rounded and ratlier narrowly 

 exposed ; disk scarcely perceptibl}^ impressed within the humeri, 

 somewhat coarsely, strongly but sparsely punctate, the punctures 

 gradually becoming almost completely obsolete at apex. Basal 

 segment of the abdomen finely, sparsely punctate, the remainder 

 not visibly punctured. Length 1.7 mm.; width 0.55 mm, 



Florida (Tampa and Hillsboro). The elytra have a transversely 

 parallelogramic basal spot, a median fascia which is broadly inter- 

 rupted at the suture, and an apical spot, produced along the 

 suture to apical third, of black. 



2. A. SUl)tropicilS n. sp. — Narrowly suboval, rather convex and some- 

 what dull, pale flavo-testaceous throughout, the antennas gradually slightly 

 dusky toward apex; head piceous-black ; elytra with an extremely feeble and 

 nubilate dark area at base, and a stronger but nubilate fascia just behind the 

 middle, narrowly and imperfectly interrupted at the suture, and not quite at- 

 taining the lateral margins; pubescence extremely short, dense and rather 

 coarse, cinereous, the longer hairs decumbent, sparse and imperceptible ex- 

 cept under high power. Head transverse, convex, finely pubescent, impunc- 

 tate, except a few punctures along the transverse crest of the occiput and very 

 near the eyes, the latter somewhat large and convex, separated by about one- 

 half more than their own width; antenna; slightly longer than the head and 

 prothorax, rather slender, gradually and moderately incrassate, the last joint 

 slightly broader but nuich shorter than the two preceding together. Prothorax 

 about as wide as the head, transversely obtrapezoidal, the apex broadly, cir- 

 cularly arcuate, the sides nearlj' straight; disk evenly convex, finely and not 

 densely piuictate, the punctures somewhat obscui-ed Ijy the vestiture. Elytra 

 three-fifths longer than wide, not (juite twice as wide as the prothorax, per- 

 ceptibly wider in the middle than at base, the sides parallel and distinctly
