Male : This species is so closely allied to H. vulpinus, that it is 

 sometimes difficult to differentiate the two. The shape, vestiture, 

 and disposition of the scales are similar, the colour of the elytra and 

 legs is often metallic black, the scales are often whitish, but the 

 distinctive character consists in the presence of a distinct spinose 

 tooth in the inner part of the knee, and of two distinct ones, facing 

 each other at the basal part of the tibias, at the beginning of the 

 grooved part. 



Female similar to that of H. vulpinus. 



Length 7-8 mm ; width 3^-4f mm.

 chestnut-brown, and having on each side four bands of flavescent, 

 round scales ; scutellum scaly ; pygidium covered with a black, sub- 

 velvety coating ; clypeus with the angles dentate, but having almost 

 no trace of median teeth ; the head and prothorax are covered wuth 

 villose flavescent hairs, and the latter has a narrow band of not very 

 dense appressed squamose hairs ; scutellum densely scaly ; elytra 

 distinctly costate, and with the intervals filled with dense, round 

 scales ; hind femora thick, and having beneath, at about the median 

 part, a sub-vertical tooth, which is not connected with the trochanters, 

 and a sub-transverse one close to the knee, the articulation of which 

 is not dentate ; the hind tibiae are broadly laminate inwardly from a
