178 MEMOIRS ON THE COLEOPTERA. 



base, not prominent, the carinae wanting; antennae rather long, notably 

 thick, similar to those of the preceding, except that the third joint is a little 

 shorter than the second, the fourth not quite as long as wide and the last 

 large, pointed and longer than the two preceding; prothorax as in oppidana, 

 fully as wide as the elytra, the latter longer and parallel, the suture about 

 equal in length to the prothorax; abdomen a little shorter and broader, 

 nearly as wide as the elytra, moderately tapering throughout, the fifth ter- 

 gite fully one-half longer than the fourth. Length 2.0 mm.; width 0.4 mm. 

 North Carolina (Asheville). 



Distinguishable at once from the preceding by the less dense 

 punctulation, longer and much heavier antennae and longer elytra. 

 The elytral suture and flanks in fully mature examples are darker 

 or piceous in color, and the pronotum in some individuals has a 

 very fine and feeble or obsolescent impressed median line. 



Strigota verecunda n. sp. Slender, rather convex, scarcely shining, black- 

 ish, the abdomen black, the elytra pale brown, the legs pale; punctures very 

 fine, not so dense as in oppidana though similarly dense on the almost opaque 

 elytra; head nearly as long as wide, scarcely dilated basally, the eyes at more 

 than their own length from the base; antennae black, long and very heavy, 

 minutely and densely pubescent as usual, paler basally, the third joint a 

 little longer than the second, more obconic in form, and, at apex, thicker 

 than the latter, the fourth not quite so long as wide, the last large; prothorax 

 larger than in either of the preceding, strongly convex, scarcely a third wider 

 than long, parallel and well rounded at the sides, much wider than the head, 

 very distinctly wider than the base and apparently wider than the apex of 

 the elytra, the latter moderately transverse, with feebly diverging sides, 

 the suture fully four-fifths as long as the prothorax; abdomen more parallel 

 than usual and with thick margins, as wide as the elytra and scarcely tapering, 

 except feebly so apically, the fifth tergite one-half longer than the fourth 

 and fully four-fifths as wide as the first. Length 1.7 mm.; width 0.45 mm. 

 Iowa (Cedar Rapids), Brendel. 



This species differs from the preceding two in its smaller size, 

 relatively much larger prothorax and in the form and size of the 

 third antennal joint. 



Strigota assueta n. sp. Somewhat similar to gnava but much stouter, 

 rather shining, similar in coloration and sculpture, except that the anterior 

 parts are piceous and that the elytra are only very little paler than the pro- 

 thorax, and not abruptly much paler as in that species; head and antennae 

 nearly as in gnava throughout, the second joint just visibly longer than the 

 third; prothorax more transverse than in the preceding, about two-fifths 

 wider than long, broadly convex and unimpressed, much wider than the head, 

 scarcely at all wider than the elytral base and not quite as wide as the apex, 

 parallel and broadly rounded at the sides; elytra rather large, moderately 

 transverse, the suture very nearly as long as the prothorax, the sides very 

 feebly diverging; abdomen about as wide as the elytra, only very feebly
