slightly, the abdomen rather strongly, shining; sculpture, punctures and 

 coloration nearly as in the preceding, the pubescence rather long and 

 bristling; head slightly wider than long, four-fifths as wide as the pro- 

 thorax, the eyes moderately prominent, at slightly more than their own 

 length from the base, the tempora moderately converging and evenly, 

 not strongly arcuate to the base; antennae rather long, black, piceous 

 basally, moderately slender apically, the third joint shorter and more 

 basally constricted than the second, fourth thicker, obtrapezoidal, not 

 quite as long as wide, four to six very slowly and evenly increasing, thence 

 parallel to the tip, the tenth barely at all wider than long, the last acutely 

 ogival, not quite so long as the two preceding; prothorax not over a third 

 wider than long, widest at about two-fifths from the apex, the sides very 

 broadly, evenly rounded, becoming slightly convergent anteriorly and 

 rather strongly convergent but still arcuate to the very minutely and 

 feebly subprominent, though obtuse, basal angles, the apex somewhat 

 wider than the base, the surface very broadly flattened or feebly im- 

 pressed medially; elytra parallel, as long as wide, fully a fifth wider, the 

 suture two-fifths longer, than the prothorax, the humeri distinctly exposed 

 at base; abdomen long, parallel, evidently narrower than the elytra, 

 the fourth impression fine and feeble, the sexual characters (cf) nearly 

 as in funesta. Length 2.3-2.8 mm.; width 0.44-0.55 mm. Pennsyl- 

 vania (Allegheny), Hamilton. 



Distinguishable from the preceding by the antennal structure, 

 the fifth joint not being abruptly wider than the fourth, by its 

 much narrower and differently outlined prothorax, longer elytra 

 and other characters. 



Homalota hesperica n. sp. More slender, depressed, dull, the ab- 

 domen shining, the sculpture nearly as in the two preceding but rather 

 finerand smoother; color dark piceous-brown, thehead and abdomen black, 

 the legs paler brown, the elytra barely visibly paler than the prothorax; 

 pubescence very short, palish but not conspicuous; head but little wider 

 than long, almost as wide as the prothorax, the eyes prominent, at their 

 own length from the base, the tempora evidently less prominent, parallel 

 for some distance, then strongly rounding to the base; antennae piceous, 

 rather stout, shorter, as long as the head and prothorax, the third joint 

 shorter and more constricted basally than the second, fourth scarcely 

 thicker, wider than long, nearly parallel, fifth abruptly thicker, the joints 

 thence distinctly increasing in thickness to the tip, the tenth three- 

 fourths wider than long, the last not quite so long as the two preceding; 

 prothorax only a fifth wider than long, widest near two-fifths from the 

 apex, where the sides are very obtusely and feebly subangulate, con- 

 verging very slightly to the apex and more distinctly and also becoming 

 straight to the base, the angles obtuse, not very sharp and not in the 

 least prominent or everted, the surface feebly impressed along the median 

 line from apex to base, the latter scarcely as wide as the apex, broadly and 

 moderately rounded as usual; elytra fully as long as wide, with very slightly 

 diverging straight sides, at base fully a fourth wider, the suture one-half
