fourth interstice slightly nearer the front, and the black colour 

 runs across the stria so that there is an appearance of a small 

 oblifiuely-elongate black patch ; the third interstice bears another 

 small black tubercle or crest a little behind the middle, and 

 another at the posterior declivity and two very small ones near 

 the apex. The hinder part of the fifth interstice bears some 

 obscure tubercles.

This is a most variable insect, and extremely difficult to 

 characterise satisfactorily owing to most specimens being more or 

 less clothed with an indumentum, which conceals the characters. 

 A fresh specimen is clothed with dull-brown scales, with usually 

 some indication on the prothorax of vittiie formed by paler 

 scales ; on the elytra there are usually patches of black scales, 

 which vary in extent up to almost covering the surface. The 

 alternate interstices are convex, and the tubercles are confined to 

 the posterior declivity, commencing, however, slightly in front of 

 it ; the third aiid fifth interstices each bear two well-defined 

 tubercles, and there are a few more or less defined granule-like 

 tubercles.
