 distinctly bifoveate; male unknown. Length .32 inch. 



24. pulzeyj*! Horn. 



3. Metasternal episterna punctate; prothorax about one-half wider than lung. 



eniarginate at apex; prosternum with a deep fovea at middle in the 



males. Length .24-..33 inch 25. apricaria Payk. 



Metasternal episterna impunctate. 

 Prosternum longitudinally sulcate, without punctured area in the males, 

 more feebly in the females. Length .28-. 32. 



26. schwarzi Nobis {septentiowiUn [I Lee). 

 Prosternum with shallow, sparsely punctured oval space at middle in the 

 males, simple in the females. Length .35-. 43 inch. 



27. latior Kirby. 



22. A. exarata Say. — Oblong-oval, robust, very convex. Color varying 

 from piceous to black, shining. Head slightly narrower tlian the thorax at apex ; 

 frontal grooves short, triangular, not extending forwaid on to the episterna; 

 eyes moderate, finely granulate ; anteuuse as long as the head and thorax, rufous ; 

 palpi rufous. Prothorax suhquadrate, about one-half wider than long, broadest 

 about the middle, wider at base than a])ex ; apex emarginate, the anterior angles 

 rounded ; base feebly bisinuate; median line distinct, abbreviated in front; ante- 

 rior transverse impression varying from moderately distinct to nearly obsolete, 

 the posterior obsolete or feebly marked at middle; basal impressions broad, 

 coarsely and usually densely punctate, very distinctly bifoveate; sides with the 

 margin narrowly but distinctly reflexed, arcuate, sinuate for a very sliort dist- 

 ance in fiont of the hind angles, which are small, acute, slightly prominent 

 and very obtusely carinate. Elytra slightly wider than the thorax, subparallel. 

 deeply striate; strife deeply and closely punctate, less distinctly toward the 

 apex ; scutellar stria usually very short or obsolete or represented by punctures, 

 rarely distinct, though shorter than in our other species of the subgenus; inter- 

 vals convex. Body beneath piceous or rufopiceous, the abdomen usually slightly 

 paler; prosternum with the sides rather sparsely punctured in front, the side- 

 pieces usually impunctate, rarely with a few scattered punctures; meso- and 

 metasternal episterna, sides of raetasternum and of ventral segments coarsely 

 ])unctate. Legs varying from rufous to rufopiceous. Length .30-. 40 inch : 

 7.5-10 mm. 



The males have on tlie pro.stenuim at middle a small, nearly oval 

 space with a few small pimctiires. The posterior tibiiP are less 

 densely pubescent on the inner side in that sex than is usual in 

 this subgenus, and the pubescence extends but for a short distance 

 from the apex of the tibia. 



Superficially this species resembles most closely A. {Leiocnemis) 

 avi.da Say, but in addition to the subgeneric characters it differs by 

 several others mentioned above. It also resembles A. fxdva DeGeer 

 of Europe. From our other species of Bradytus it is distinguishable 

 by the characters given in the table.
