A. proflroiuus Brabm. — Oblong, moderately convex, black, sinning; sides 

 of tliorax and elytra pale yellow, tbe latter with an elongate fuscous space nar- 

 row near the humerus and broader posteriorly, legs yellow. Antennae testa- 

 ceous, club fuscous. Head feebly convex, the male with slight elevation at 

 middle, surface smooth with a few nearly obsolete coarse punctures near the 

 sides % , sparsely finely punctate 9 • Clypeus hemihexagonal, very broadly 

 feebly emarginate, the angles rounded, sides arcuate, gense moderately prominent, 

 subacute. Thorax slightly narrower in front in both sexes, the sides inore ar- 

 cuate in the male, hind angles well defined, the apex slightly obtuse, base arcuate 

 with fine marginal line ; disc more convex in the male, the middle nearly smooth 

 with a few coarse punctures toward the hind angles, in the female less convex, 

 with only the anterior portion of the middle region smooth, otherwise with mod- 

 erately coarse sparse punctures. Elytra as wide at base as the thorax, humeri 

 distinct, but obtuse, strise moderately deep, moderately coarsely crenately punc- 

 tate, the intervals convex with few sparsely placed fine punctures 9 ^ or densely 

 punctate on each side % . Mesosternum opaque each side, smoother at middle. 

 Metasternum yellow at middle, sides opaque, sparsely punctate. Abdomen 

 sparsely obsoletely punctate. Anterior tibiic smooth in front, tridentate exter- 

 nally and crenate above, the first tarsal joint shorter than the second. Posterior 

 femora almost entirely smooth, a few coarse punctures near the knee, the first 

 tarsal joint nearly as long as the next three. Length .22-.30 inch : 5.5.-7.5 mm. 



Male. — Front slightly more convex at middle. Head and thorax with very 

 few punctures. Anterior tibial spur stout, suddenly flexed inwards at tip. Elytral 

 intervals densely punctulate at their sides, smooth oniy at middle. Posterior 

 femora stouter. 



Female. — Front evenly convex. Head and thorax with numerous punctures. 

 Anterior tibial spur slender, acute, nearly straight. Intervals with very few 

 punctures. 



In both sexes the metasternum is yellow, flat, with a median lon- 

 gitudinal sulcus, deeper in the male, the flat region around the groove 

 is closely and coarsely punctured in the male and very sparsely punc- 

 tate in the female. , 



The elytral pubescence is quite fine and easily abraded, but more 

 permanent than in Walshii, and less distinct than in femoralis. The 

 present species is larger than femor'alis, more shining, and with more 

 yellow and less fuscous on the elytra. 



Occurs very commonly in Europe, and in our country has been 

 collected by Prof. Fernald in Maine. I have a specimen from Mon- 

 treal, Canada. 



A. teiiuisf riatus n. sp. — Form rather slender, as in stercorosus, moderately 

 convex, entirely rufotestaceous, feebly shining. Head feebly convex, front with- 

 out trace of tubercles, surface finely alutaceous, sparsely punctulate ; clyijeus 

 very feebly emarginate iu front, the angles rounded, sides oblique, very feebly 

 arcuate, the geuse not at all prominent. Thorax distinctly narrowed in front, 

 the sides feebly arcuate, margin fimln-iate, hind angles well marked, but obtuse ; 

 base arcuate with fine marginal line ; disc moderately convex, very sparsely
