and punctulate, the stria very fine, not entire; elytra a third longer 

 than wide, gradually feebly inflated posteriorly, distinctly less than 

 twice as wide as the prothorax, the striae very fine, not impressed, 

 feebly punctate, the intervals flat, with sparse and extremely minute 

 punctulation; dorsal punctures small and feeble, at basal and apical 

 fourth. Length 4.5-4.7 mm.; width 2.1-2.25 "ini- California.

Head and elytra black, shining, the prothorax above and beneath testa- 

 ceous; elytra each with two flavate vittae; coxae and entire abdomen 

 rufous, the meso- and metasterna and epipleura black 4 



4 — Head moderate, distinctly narrower than the prothorax, the eyes 

 moderate, prominent. Surface nearly smooth, with minute sparse 

 punctulation; antennae unusually long, much more than half as 

 long as the body, black, the first three joints in great part testaceous; 

 prothorax three-fifths (c?') to two-thirds (9) wider than long, the 

 sides rather strongly rounded and finely reflexed to the very obtuse 

 angles, which are minutely prominent at tip; basal lobe punctulate, 

 the sulcus shallow, not sharply defined; surface convex, shining, 

 with fine sparse rugulosity, the median stria fine, not well defined 

 and abbreviated; elytra two-fifths longer than wide, feebly dilated 

 behind the middle, just twice as wide as the prothorax, the striae 

 extremely fine and feeble, minutely punctulate, the flat intervals 

 minutely, sparsely punctulate; each elytron with a flavate vitta 

 from the middle of the base not quite to the apex near inner third, 

 there slightly swollen, also with a submarginal vitta of equal width, 

 extending to posterior fourth, the reflexed margin black; pale vittae 

 equal in width and much narrower than the outer black vitta; legs 

 black, the femora pale at base, the tibi« fusco-flavate except at tip. 

 Length 5.2-5.7 mm.; width 2.25-2.4 mm. Kansas.. . .aemula n. sp. 



Head larger, barely visibly narrower than the prothorax; antennae not 

 so long 5 



5 — The pale elytral vittae much narrower than the external black vitta 

 as in the preceding; elytra more elongate; head finely and feebly, 

 very minutely punctulate, with two larger, more widely separated, 

 and two smaller, more anterior and more approximate, impressions, 

 each pair on a transverse line through the eyes, the latter prominent 

 though moderate in size; antennae not very slender, half as long 

 as the body, colored as in cemula; prothorax one-half wider than 

 long, the sides evenly, subcircularly rounded and narrowly reflexed 

 to the obtuse but sharp basal angles, which are at a short distance 

 from the basal lobe, the sulcus shallow and not sharply defined; 

 surface convex, shining, with fine sparse rugulosity and minute 

 sparse punctures, the stria fine, not entire; elytra slightly less than 

 one-half longer than wide, very gradually and slightly broader 

 posteriorly, fully twice as wide as the prothorax; vittae nearly as 

 in the preceding, the submarginal a little shorter, the sculpture nearly 

 similar, except that the fine striae are rather more distinct; legs 

 black, the femora pale at base, the tibiae obscure rufous, black at 

 tip. Length 5.3 mm.; width 2.2 mm. Iowa (Keokuk).
