Black, clothed with a short, appressed flavescent pubescence on the 
under and upper sides ; antennae black ; head and prothorax very deeply 
sub-scrobiculate punctate, frontal line distinct or not ; elytra without any 
traces of costules, very closely punctate shagreened, the patches and bands 
are yellow with a more or less pronounced orange-yellow tinge, on each 
side are three transverse bands, a basal with a bi-sinuate hind border, an 
ante-median deeply bi-sinuate in the anterior border and tri-sinuate in the 
posterior, a post-median one tri-denticulate on each border, and a supra- 
apical patch emitting a short spur towards the outer margin, all the three 
bands are continued downwards for a short distance along the outer 
margin, and the basal band is even connected there with the ante-median 
band. Fahroeus mentions a variety in which the basal band does not 
quite reach the humeral part, and another where this basal band is dilated 
inwardly, and becomes connected with the intermediate band towards the 
sutural part. This goes to show that the disposition of the bands is very 
variable.

Black, clothed on the head and prothorax and on the under side with a 
dense flavescent silky pubescence ; antennae black ; head and prothorax 
covered with rugose, nearly confluent punctures, the median sulcus of the 
latter part is very well marked ; elytra sub-foveate shagreened in the 
anterior part, more distinctly and more closely shagreened in the posterior, 
and having on each side, but only in the large development, two somewhat 
distinct longitudinal costules in the anterior part only; on each elytron are 
four equi-distant, more or less quadrate, or rounded pale yellow or orange 
yellow patches disposed lengthways between the median dorsal part and 
the suture, and disconnected from the latter; along the outer margin is an 
elongated band running from the humeral part and dilated triangularly 
opposite the second dorsal patch, where it ends ; lower dowu, opposite to 
the third dorsal one, is another patch absolutely similar in shape (fig. 81) ; 
in the first varietal form (fig. 82) the basal patch nearly coalesces with the
