sides becoming more oblique behind, abruptly more sinuate just 

 before the angles, which are right, very sharp and prominent; sur- 

 face nearly similar but the margins are more equally reflexed through- 

 out the length; elytra oblong, three-fifths longer than wide, two- 

 fifths wider than the prothorax, more rapidly and obtusely rounded 

 at tip; striae rather fine, just visibly and evenly impressed through- 

 out the width, the seventh a fine loose entire series; punctures every- 

 where notably fine and separated by more than twice their diam- 

 eters; foveae small, near two-fifths and two-thirds. Length (c? 9).

23 Elytral punctures strong and widely separated in the series by 

 nearly twice their diameters as a rule. Body smaller and rather 

 more depressed than in the three following, black, with subaeneous 

 lustre, the neck testaceous, the elytra testaceous, with a rather 

 sharply defined transverse black fascia just behind the middle, 

 somewhat prolonged suturally; under surface black, the epipleura 

 and legs testaceous; head fully three-fourths as wide as the pro- 

 thorax, the eyes moderately prominent; antennae long, slender and 

 testaceous; prothorax a third wider than long, widest at two-fifths 

 from apex, the sides rounded, oblique behind, becoming parallel for 

 a short distance from the angles, which are right; stria strongly 

 impressed, extending between the feeble impressions; foveae large, 

 punctulate, with a deeper central part, the carina very short, not 

 attaining the angles; elytra oblong, parallel, circularly rounded be- 

 hind, three-fifths longer than wide and one-half wider than the pro- 

 thorax; striae moderate, the seventh a subobsolete series of very 

 minute punctules; foveae at three-sevenths and three-fourths.

Elytral punctures close-set in the series 24 



24 Head smaller, with moderately prominent eyes, much narrower than 

 an elytron. Body short, rather convex, greenish-black, the neck 

 barely at all pallescent; elytra flavo-testaceous, with a broad and 

 nubilous dusky median fascia, longest toward the suture; under 

 surface black, the abdomen more or less rufescent, the legs pale; 

 head scarcely three-fourths as wide as the prothorax, the antennae 

 long, slender, fuscous, pale basally; prothorax a third wider than 

 long, widest barely before the middle, the sides broadly rounded, 

 generally quite to the angles, which are minutely prominent and 

 very sharp; margins strongly reflexed even apically; surface sparsely 

 punctate basally, having feeble transverse impressions and a very 

 fine and scarcely impressed stria between them; foveae elongate, 

 linear, moderately deep, the carina very short, at the angles as usual; 

 elytra but little over one-half longer than wide, parallel, broadly 

 ogival at apex, two-thirds wider than the prothorax, the striae mod- 

 erate, subequally and slightly impressed throughout, the punctures 

 very moderate, separated by their own diameters or less, the seventh 

 stria barely traceable and in part only by a very fine series; foveae 

 small, at two-fifths and two-thirds. Length (d 71 9 ) 6.7-7.6 mm.;
