9.7-10.0 mm.; width 3.6 mm. Rhode Island, New Jersey and 



Indiana blandus Germ, 



B — Similar to cincticollis but still more depressed and more piceous in 

 color; eyes similarly large but not quite so prominent; evenly 

 rounded sutural tips of the elytra more posteriorly prolonged, 

 the sinus distinctly deeper. Length (9) ii-O mm.; width 4.2 



mm. Texas (Galveston) deplanatus Chd. 



Elytra not so elongate, more oblong-suboval in form, more convex and 



rounding posteriorly from only a little behind the middle 21 



21 — Prothorax nearly as in the preceding but more subprominently 

 rounded at the middle of the sides, the posterior obliquity but very 

 faintly sinuous, the angles very obtuse, with the tips not very dis- 

 tinctly defined. Body more convex than in cincticollis, shining, 

 black, with diaphanous side margins and piceous legs; head slightly 

 elongate, rhomboidal, with moderately abrupt neck and prominent 

 eyes, which are not so large and less prominent than in cincticollis, 

 three-fourths as wide as the prothorax; labrum narrower than in 

 the preceding, the mandibles smaller; antennae testaceous, slender, 

 fully half as long as the body; prothorax a fifth wider than long, 

 the sides broadly refiexed and pale, subangularly prominent at or 

 just before the middle; surface and foveae nearly as in cincticollis; 

 base equal to the apex, strongly arcuate at the sides; elytra shorter, 

 more oval and more convex, more gradually rounded behind, the 

 sinus very shallow; surface of each feebly impressed at the point 

 noted in the preceding species; striae smooth, more impressed and 

 relatively coarser at tip; intervals feebly convex; anterior male tarsi 

 somewhat feebly dilated. Length (cT 9 ) 9.5-10.0 mm. ; width 3.7-3.8 

 mm. Pennsylvania (locality not more definitely recorded). 



pennsylvanicus n. sp. 

 Prothorax nearly as in pennsylvanicus, strongly refiexed at the sides, the 

 general outline of the body and elytra and the pronounced con- 

 vexity of the latter similar. Size materially larger; coloration and 

 polished lustre similar; head rhomboidal, evidently narrower than 

 the prothorax, the eyes prominent but not quite so large as in 

 pennsylvanicus, the antennae longer and with much more elongate 

 joints in the male, similar in coloration, nearly two-thirds as long 

 as the body, the third joint in similar manner just visibly longer than 

 the fourth; prothorax with strongly refiexed diaphanous sides and 

 in this and other respects as in pennsylvanicus, but not quite so 

 evidently wider than long, the sides not quite so widely refiexed as 

 in reflexus; foveae similar, deeply concave; elytra larger than in 

 that species, nearly two-thirds longer than wide, fully twice as 

 wide as the prothorax, parallel, rounding in posterior two-fifths, 

 with feeble sinus; surface convex; striae rather fine, nearly smooth, 

 deeply impressed; intervals broadly convex, the three punctures 

 of the third rather strong, the first at the third, the other two at 

 the second, stria; met-episterna fully twice as long as wide; anterior 

 male tarsi narrowly dilated, the fourth joint symmetrical. Length 

 (cT) 1 1.0 mm.; width 4.2 mm. Ontario (Ridgeway), — Knaus.
