Elytra fulvous, witli a black sub-basal spot and longitudiual 

 broad band on either side of suture extending almost to 

 the apex, pubescence uniformly cinereous. Last joint of 

 male club as long as the preceding two united, which are 

 very large and equal Hornii. 



Elytra black with a sub-basal sinuous transverse piceous 

 band, which bears dense Avhitish pubescence, all three 



joints of male club very large and equal perplexus. 



Prosternum narrow and short. 



Elytra black, with three, more or less confluenj:, broad 

 piceous spots on either side of suture ; whitish pubes- 

 •cence arranged in three distinct transverse fasciae, all 

 three joints of male antenna? club very large and equal, varicolor. 



A. piceus Oliv. Elongate, convex, black, clothed with short, semi- 

 erect, yellow pubescence. Head coarsely punctate, sparsely pubescent. 

 Antennte rufo-testaceous. Thorax black, coarsely punctate, pubescent at 

 sides and base. Scutellum pubescent. Elytra black, or rufous, coarsely 

 punctured, clothed with very sparse, brownish pubescence. Body beneath 

 black, coarsely and densely punctate, clothed with semi-erect, yellow 

 hairs. Prosternum long and wide. Legs rufous. Length .14-.20 inch; 

 3i-5 mm. (Fig. 26.) 



3fale. Antennse with first joint large, suboval ; second smaller ; joints 

 3-8 small ; 9-11 forming the club, of which the first two joints are wide 

 but very short, the last wide, extremely long, pointed at end — equaling all 

 the preceding part of the organ. (Fig. 22.) 



Female. Antennal club compact, not quite equal to all the preceding 

 joints, made up of three joints of which 9-10 are equal ; Avhile the last 

 equals the two united. (Fig. 23. ) 



Under this name I hav*s[nc\m\ed rujijjemm, dichrous, spurcus, megatomn, 

 as I can see no characters by which they can be separated. The sparselj^ 

 pubescent uniformly colored elytra, the broad prosternum and the struc- 

 ture of the male antennae are diagnostic. 



Occurs everywhere.

 Elytra black, sparsely pubescent, a small smooth spot on either side of

 Length .21 inch ; 5.5 mm. (Figs. 29, 30.)
