Tbe I'orms described under («), {il), and (c), liave sui^li an entire!}- different a]i]iear- 

 ance as regards the pattern of tlie elytra, tinit 1 at Krst believeil (liem to represent 

 three distinct species. But as the punctuation, the outline of tlie jjrothorax, the 

 form of the elytra, the shape of the femora, i^iv., are entirely the same in a good 

 number of specimens of the various forms, whilst they are diii'erent in tlie other 

 species of this genus, I consider all these different-looking s])ecimeus to lielong to 

 one species, especially as there are examples witli an intermediate coloration. 



Punctuation of the head exceedingly fine ; middle of the vertex and sometinu-s a 

 triangnlar sjiace in the centre of the front more densely pu))escent. Antennae grey, 

 ■with the tip of the third joint lilack. Prothorax about a third shorter than long, 

 impnnctate, with a deep transverse groove in front and al t1ie l)ase ; lateral teeth 

 close to the basal constriction. Scntellum truncate af the ajiex. Elytra convex, 

 narrowed towards the tip in the mulr, much less so in the ffmale; base beside the 

 scntellum, a])ex, and sometimes the Ijasal imjjression near the shoulder almost im- 

 pnnctate, whilst the middle of the disc is rather coarsely and more densely 

 punctured ; in specimens with a close pubescence the punctures seem to be smaller, 

 as they ai'e more or less concealed by the hairs. Femora rather slender ; posterior 

 ones with a black ring near the apex.

Black, covered with a brownish and somewhat asiiy jiubescence. Front of the 

 head finely and rather densely granulated ; vertex smooth, with fine punctures only 

 behind the eyes ; two small s])ots in the (H'ntre of the front, and the middle of the 

 vertex more densely puliescent. Antennae and legs with a grey pubesi'ence ; the 

 base of the joints whitish ; the apex of tlie third one black and clothed witli black 

 hairs; the tip of the fourth and fifth also more or less blackish. Prothorax im- 

 pnnctate, disc evenly convex between the usual transverse grooves ; lateral teetii 

 ])laced close to the basal constriction, and somewhat curved. Scntellum tra])ezi- 

 form, broader than long. Flytra convex, distinctly narrowed l)eliin(i, with the 

 shoulders slightly mnnded ; imerstices of the imnctures larger than the punctures.
