they consist of a longitudinal median line on the head; a patch 
resembling the letter M on the prothorax and also the extreme 
lateral margins of the same ; and on each elytron a spot near the 
apex of the scutellum, a short longitudinal line between the spot 
and the shoulder, a bisinuate longitudinal line from the shoulder 
nearly to the middle of the elytron, a transverse zigzag line 
touching neither suture nor lateral margin slightly in front of 
the middle of the elytron, and two spots near the apex. In some 
examples these markings are larger and more numerous as well 
as nearly black in color. In one example (which the discovery 
of more specimens may possibly prove to be a distinct species as 
the prothorax seems more feebly punctulate and its transverse 
impression is scarcely traceable) the markings are black and those 
on the elytra present the appearance of three coarse vittze (the 
inner two vittz three or four times interrupted, the external one 
interrupted only near the base, all of them dilated here and there 
so as to coalesce in places) and the prothoracic discal markings 
consist of black lines touching the apex but not the base. I 
think this form might be called “ var extrema” as I have not seen 
any specimen really intermediate between it and the type ; 
nevertheless I think its markings are only an extreme develop- 
ment of those of the type.
