The design and colours of the elytra are much varied. 

 Near the base is an oblique, moderately wide, yellowish 

 fascia, which is far from reaching the suture, and is mar- 

 gined with brassy-black, this latter colour occupying the 

 whole humeral space, leaving a spot of pale rufous only 

 near the scutellum ; behind the middle is an oblique 

 and entire fascia, also of moderate but considerable width, 

 margined anteriorly with brassy-black; the whole space 

 behind this is brassy-black, except the white tips ; the 

 whole surface is very glossy, and is roughened only by 

 the setiferous punctures, which are very minute.

This seems to be the position of this species, which, 

 although taken by me, was not reserved for my own 

 collection.
