Length 40,5 mm., breadth at the shoulders 14 mm. ; 

 length of the antennae 51,5 mm. — Black; entirely covered 

 with a close whitish tomentum , more or less fuscous on 

 the tibiae outside , intermixed with stiff black hairs on the 

 tarsi , and of a mouse-grey color on the fifth and following 

 joints of the antennae ; the middle of some of these joints 

 however is inconspicuously spotted with a greyish pu- 

 bescence. 



Impunctate. The head large , the eyes large , sub-ap- 

 proximate in front; a naked and glossy bifurcate spot be- 

 tween the upper lobes of the eyes, and some naked and 

 flattened granules along the hind margin of the upper 

 lobes. The scape of the antennae half as long as the 3rd 

 joint , the 3rd joint one third longer than the 4th , the 

 4th — 10th of equal length, the 11th joint one third lon- 

 ger than the 10th. 



The pronotum with two raised transverse lines close to 

 the anterior margin , and three similar ones on the middle 

 of the disk , of which the median one is widely interrupted 

 in the middle and the posterior one shortened at both 

 sides; behind these raised lines as well as on the base of 

 the lateral spines which are straight and naked at the tip , 

 some naked flattened granules may be observed. The late- 

 ral margins of the scutellum nearly parallel, the apex 

 broadly rounded. 



The elytra much attenuated towards the apex, with a 

 short transversely directed tooth at the shoulders , and pro- 

 vided on the basal half with glossy black slightly trans- 

 verse granules which are very densely set on the shoul- 

 ders. On the posterior half of the elytra a few similar
