basal impressions are not obliqne. The elytra are usuall}- brownish 

 in color, although in a few specimens seen they are not paler than 

 in the last named species. The antennae are rufous, and ihe legs 

 usually so, though sometimes piceorufous. 



Like eschaclioltzl, it occurs in Alaska and Kamchatka. 



15. A. bruiiiiipenniN Dej. — Form nearly oblong, elongate, convex. Color 

 black, at most scarcely teneous, the elytra often piceons or brown ; surface 

 shining in the males, finely alutaceous in the females. Head nearly as wide as 

 the thorax at apex ; frontal grooves short, distinct, anteriorly not extending on 

 to the epistoma; antennse slender, shorter than the head and thorax, piceons, 

 the first two joints usually paler; palpi piceous, usually paler at the extreme tip. 

 Prothorax about one-half wider than long, as wide at base as apex, impunctate 

 or rarely with a few scattered punctures at apex, more or less sparsely punctured 

 at base, usually more or less transversely wrinkled along the median line; apex 

 emarginate, the anterior angles rounded ; transverse impressions moderate or 

 feeble; median line fine, entire or abbreviated for a short distance in front: 

 basal impressions broad, deep, more or less coarsely punctate, bifoveate, the inner 

 fovea longer than the outer; base truncate; sides with the margin narrowly re- 

 flexed, arcuate from apex to base or sometimes oblique for a short distance in 

 front of the hind angles, which are obtuse and obtusely carinate. Elytra 

 together scarcely wider than the thorax and less than twice as long as wide, 

 striate; strise entire, punctate to behind the middle, the scutellar stria moderate, 

 the eighth with the row of ocellate punctures widely interrupted at middle; 

 intervals rather broad, flat or nearly so ; humeri rounded. Body beneath black ; 

 meso- and metasternal episterna, sides of metasternum and of the first two ven- 

 tral segments impunctate t>r at most sparsely punctate. Legs varying in color 

 from black to nearly rufous, usually piceous or rufopiceous; inner margin of the 

 middle and hind femora with two setigerous punctures; posterior tarsi with the 

 three basal joints not or at most veiy feebly grooved on the outer side. Length 

 33-.45 inch ; 8.25-11.25 mm. 



In the males the middle tibije are normally dentate. 



This specie.s, as above defined, includes what have been known 

 heretofore in collections in this country, at least, as A. hrminipennis 

 Dej. and .4. h tjparhorea Dej. The former name has been i-etained, 

 as 1 regard it as more than probable that the species known as 

 hi/perborea in American collections is not the hfjperborea of Dejean, 

 The original description does not apply to the present si)ecies, while 

 Dejean's remark.s, as well as those of Putzeys, who had the type 

 before him, seem to refer to a different species. 



As might be expected from its wide geographical range, consider- 

 tible variation is exhibited, and several forms might be selected, 

 which, if studied from uniques or from a very small series of speci- 

 mens, would doubtless be regarded as distinct .species. These, how-
