31. A. sodalis n. sp. — Broad and stroiifjly depressed, rather shining, black 

 throughout, the femora piceous; tibise and tarsi pale testaceous; antenna? pale- 

 throughout, sometimes piceous distally; pubescence fine, short, even, plum- 

 beous and somewhat sparse. Head subquadrate, slightly transverse, broadly 

 truncate and medially impressed at base, the angles distinct but rounded j 

 tempora short but parallel, not as long as the eyes, the latter rather large and 

 prominent; surface polished, coarseW sparsely and somewhat unevenly punc- 

 tate, with a broad uneven and entire smooth line; antennae slender but rather 

 strongly incrassate, fully as long as the head and prothorax, the tenth joint 

 much longer than wide, second shorter than the third or fourth, the latter 

 equal and distinctly shorter than the fifth. PrntJtorax much narrower than 

 the head, as long as wide, moderately convex, widest and obtusely angulate 

 at apical fourth, the sides thence somewhat strongly convergent and straight 

 to the basal margin ; apex broadly arcuate; collar rather long, roughly sculp- 

 tured, cylindrical, finely and feebly constricted at base; punctures strong but 

 someAvhat fine, dense. Elytra large, two-thirds longer than wide, fully twice 

 as wide as the prothorax, just visibly wider a little behind the middle than at 

 base; apex broadly, obtusely rounded; humeri very widelj' exposed; disk fiat, 

 the post-scutellar impression wide and distinct; omoplates feeble; punctures 

 strong but not coarse, well separated. Abdomen broad, feebly alutaceous and 

 reticulate, extremely minutely, closely punctate throughout, the pubescence 

 not at all consjiicuous. Zf^s rather long and slender. Length 3.1-3.2 mm. ; 

 width 10-1. 2 mm. 



Indiana. 



A very distinct species, to be readily known b}' its broad de- 

 pressed form, peculiar outline of the prothorax, coarse cephalic 

 sculpture and other characters. It seems to lead quite naturally 

 to the peculiar group of spotted species which follows. The sex 

 of the two specimens before me is not determinable. 



32. A. lieroicilS n. sp. — Rather stout and convex, polished, black 

 throughout, the antennte fuscous; legs testaceous, the femora darker; each 

 elytron with two large rufous spots, one suboval at Ijasal fifth, the other more 

 rounded at apical fourth; pubescence rather long, even, semi-erect, coarse, 

 sparse but pale and conspicuous. Head nearly as long as wide, convex, broadly 

 arcuato-truncate and broadlj", feebly, medially impressed at base, the angles 

 broadly rounded; eyes large, prominent, at a little less than their own length 

 from the base; punctures fine, deep, somewhat close-set, with a wide impunc- 

 tate line which is subobsolete toward base; antennte stout, incrassate, shorter 

 than the head and prothorax, the tenth joint scarceh' as long as wide. Pro- 

 thorax quite distinctly narrower than the head, scarcely as long as wide, 

 rounded at the sides anteriorly, ol)tusely constricted at basal fourth, rather 

 coarsely, closely and strongly punctate. Elytra three-fourths longer than wide, 

 twice as wide as the prothorax, the sides parallel and feebly arcuate; apex not 

 very obtusely rounded ; humeri widely exposed, becoming transverse near the
