Prothorax usually a little broader than long in female, but in male 

 sometimes scarcely as broad as long, never strongly widened as in meles ; 

 widest half way between the middle and the anterior edge; sides rounded 

 and swollen, anteriorly strongly rounded, posterior margin wider than 

 anterior; densely roughly finely punctured; dorsum depressed more 

 behind than in front. In perfect specimens the scales form a narrow 

 brown or gray median stripe bordered by wide dark bands, these are 

 bordered by light brown metallic bands which reach down onto the sides, 

 below these again a dark band which extends back onto the humeri, 

 remainder of side and venter pale metallic brown. Pale hairs usually 

 intermixed with scales that form the bands. The entire system of bands 

 or stripes may be obsolete, indistinct or entirely wanting or any one or 

 more of them may be missing, even in specimens recently issued from 

 the pupa. 



Scutellum minute triangular, clothed with scales of same color as 

 median thoracic stripe. 



Elytra about three times as long as prothorax, almost egg shape, 

 flattened at the base, humeri strongly rounded, convexly prominent, 

 sides sometimes rounded but usually nearly parallel for four-fifths of the 

 length, and then rounded to the tips which are not sharp; finely striately 

 punctured, interstitial spaces very slightly elevated, sometimes the odd- 

 numbered alternate spaces show more strong elevation; scales usually 

 yellowish brown, gray or dark brown but may vary in both direction, 

 hairs black or white or both ; even in carefully bred specimens the pattern 

 is extremely variable, passing from those entirely of one color (gray to 

 dark rich brown) to those which are tessellated on almost all the inter- 

 spaces. In some the sutural interspaces are alternately maculated with 

 pale and dark brown and the alternate interspaces more or less marked 

 in the same manner; usually the scales on the last interspace arc paler. 

 A broad common darker sutural basal spot is rather general, this may- 

 extend for any distance back on the elytra along the suture, the farther 

 back it reaches the broader it is at the base. Some specimens have the 

 hairs alternating black and white on the interspaces, others black on all 

 and more rarely white on all; they are however very uniformly curved 

 backward lying about one-half down and are long or short, but slender 

 and pointed. 



Venter with thoracic portion usually clothed with paler scales, more 

 rarely with intermixed hairs; abdominal portion more hairy, especially 

 in female on last two segments; mesosternal middle coxal process narrow 

 almost linear, parallel sides ; intercoxal process of third abdominal segment 

 broad and sloping to a point. 



Legs: femora usually darker brown than tibia? or tarsi, clothed more 

 or less densely in front with scales, behind usually sparsely clothed with 

 hairs, tibia? and tarsi variable in color with rather long pale hairs; front 

 fcibias slightly curved inward in male, spines on the inside of the middle 

 tibia vary in length, crown of spines very short and blunt. 



Stem of male gentialia (Plate XXIV, fig. 10), from above narrow, 

 parallel, sides uniformly thickened, gradually curved on the last third 

 to a narrowly rounded point; viewed from the side last two-thirds
