Casey — A Revision of the American Paederini. 63 



broadly rounded, the base very much more broadly truncate ; protho- 

 rax elongate-oval, only slightly narrower than the head, widest at two- 

 fifths from the apex; elytra In the female only slightly longer than wide, 

 a fifth wider and longer than the prolhorax, slightly wider than the 

 head, parallel, the punctures very coarse and rather close-set; abdomen 

 subequal in width to the elytra, the sixth segment narrowly and feebly 

 impressed along the middle in the female; male unknown. Length 



4.9 mm.; width 0.8 mm. North Carolina carolinae n. sp. 



Body stout ; coloration as in the preceding, except that the femora are pale, be- 

 coming black in outer third to half, the tibiae and tarsi piceous through- 

 out; head in the male but slightly longer than wide, the eyes rather 

 convex and prominent, moderate in size, the sides behind them strongly 

 convergent, straight for nearly the length of the eyes, then broadly 

 rounding into the truncate base, which is moderably narrow; in the fe- 

 male nearly similar, except that the sides behind the eyes are only feebly 

 convergent and the base more broadly truncate, the basal angles equally 

 rounded in both sexes; prothorax rather stout but elongate-oval, about 

 as wide as the head ; widest only slightly before the middle, the sides 

 broadly arcuate; elytra very large, parallel, deeply, moderately coarsely 

 and rather sparsely punctate, convex, very slightly longer than wide 

 and almost similar in the sexes, very much wider than the head and much 

 wider and longer than the prothorax in both sexes; abdomen parallel, 

 slightly narrower than the elytra.. Male with the apex of the fifth ven- 

 tral transversely truncate at apex, the slit of the sixth narrow and very 

 deep, its sides parallel and straight posteriorly, gradually and slightly 

 converging in less than anterior half to the narrowly rounded bottom, 

 the surface distinctly impressed in prolongation of the slit; sixth ven- 

 tral of the female impressed along the middle as usual. Length 5.3-5.7 

 mm.; width 1.2 mm. Texas (El Paso), — Mr. G. W. Dunn. 



saginatns n. sp. 



3 — Legs black or piceous-black, the femora pale in more than basal half. .4 

 Legs pale throughout, nevermore than shaded slightly with piceous in the 



region of the knees 5 



4 — Larger species, the elytral punctures much less coarse, moderately slen- 



der, the head but little longer than wide, the eyes moderate in size, 

 prominent in the male, less so in the female; sides behind them rather 

 strongly convergent and feebly arcuate in the former, less convergent 

 and more arcuate in the latter, sex; base truncate, the angles distinctly 

 rounded in the female, more narrowly so in the male; antennae rather 

 stout, piceous-black, pale toward base; prothorax but slightly elon- 

 gate, as wide as the head in the female, relatively a little narrower in 

 the male, broadly arcuate at the sides and widest at apical third ; elytra 

 quadrate, less convex than usual, the punctures only moderately coarse 

 and rather close-set, distinctly wider than the prothorax, as long as the 

 latter in the male and a little longer in the female; abdomen parallel, a 

 little narrower than the elytra in both sexes. Male with the fifth ven- 

 tral transversely truncate at apex, the notch of the sixth elongate-oval in 

 form and only slightly more than twice as deep as wide, rather broadly 

 rounded at the bottom, the adjoining surface of the segment not at all
