denser than on pygmaeus, but rather larger than on the other 

 species of BB (except evanescens) ; the propygidium is not 

 enormous as on the species of DD, and the ctypeus is sharply- 

 truncated in front, not rounded as on evanescens ; or triden- 

 tate as on opaculus. All the species of AA, B, C, are 

 considerably larger, except funereus, which is a deep black 

 species with very different clothing, and pictvs, from the 

 description of which it differs in many particulars of colour 

 and sculpture. The three specimens before me all differ 

 slightly in colour, this in general being of a very dark-brown, 

 with the abdomen (and elytra or not) obscurely paler; on the 

 under-surface the clothing is mostly of a dingy-white; on the 

 upper-surface of one specimen it is not much darker, but on 

 the others it is considerably darker (almost black in parts), in 

 general, however, it has an ashen appearance. 



These specimens are presumably males (they certainly 

 have no sexual brand on the elytra) ; two others are possibly 

 females of the species, they have the elytra more coarsely 

 sculptured, with the alternate interstices conspicuous, and 

 with a small irregular shining space (presumably the sexual 

 brand) near the apex of each, club of the antennae consider- 

 ably smaller, abdomen rather more convex, pygidium larger 

 and propygidium smaller, clothing stouter (this is notably 

 the case on the hind parts), that on the elytra blackish (except 

 at the base, suture, and apex), and that of the pronotum 

 more conspicuously variegated, being pale except on a rather 

 distinct medio-basal space, where it is almost black.

(5 . Bright-castaneous, some of the projecting parts 

 darker. Densely clothed with rusty-red hair, elytra and apical 

 half of pygidium glabrous. 



Head flattened and with small punctures between eyes; 

 clypeus almost vertical, and with conspicuously elevated 

 margins, especially in front; mentum narrow and conspicuous. 

 Antennae ten-, club three-jointed, rami of club about as long 

 as inner part of front tibiae. Prothorax with a somewhat 

 flattened excavation for more than half its width, the excava- 

 tion marked on each side by a strong pointed horn (curved 

 inwards at its tip), the middle of the apex with another but 

 smaller and more acute curved horn, produced over head; 

 with dense, partially concealed punctures. Scutellum 

 with similar punctures to pronotum. Elytra distinctly 

 wider than prothorax, sntural and marginal striae well- 

 defined, the others feeble ; with irregular series of sparse and 

 mostly small punctures. Pygidium with dense punctures
