 The fine erect hair-like setae clothing the upper surface of this 

 species and falling into regular lines along the elytral interstices, 

 though much shorter than those of D. jyilosus and very differently 

 disposed, yet seem to connect it with that species. Structurally, 

 however, it is much nearer to D. ventralis. The pattern formed 

 by the scales is variable ; some examples are almost uniformly 

 dark fuscous shading here and there into black ; others are of an 

 ashy fuscous tint with the prothorax laterally spotted or striped 

 with dull whitish-grey, the latter colour extending itself to the
