band is very distinct, and the suture and the median line of the pro- 
thorax are also narrowly banded with greyish white, but I have since 
seen many examples light grey above and in which the discoidal band 
alone was visible, although very weakly, and had even disappeared 
altogether.

Narrow, elongated ; clothed with a sub-flavescent pubescence somewhat 
remote on the head, absent on the prothorax, very dense on the elytra ; 
black, with the prothorax red and the elytra straw-colour and having each 
three black patches, the basal one rounding the shoulder and descending a 
little along the suture, the second one situated at about the median part 
of the disk is elongated, and the third one extends over the whole apical 
part ; the antennae are long and filiform ; the head is deeply but remotely 
punctate and the frontal part more pubescent than the apex ; the pro- 
thorax is narrowed into a long, slender neck, is deeply but remotely 
punctate, has a deep basal median impression, and a very short line in the

Black, head with a broad frontal patch extending from the epistome to 
the vertex ; prothorax red with two small black patches in the anterior 
part, tibiaB reddish ; antennae long, somewhat slender, the intermediate 
joints more than twice longer than broad, and not much compressed ; 
head and prothorax glabrous or nearly so, the former is somewhat closely 
and deeply punctured, the punctures are more remote on the prothorax 
which is strongly attenuated into a neck from about the median part, and has 
a deep, broad basal impression and a short line in the centre ; elytra very 
finely aciculate shagreened, clothed with a very short, appressed greyish 
flavescent pubescence which does not however hide the colour of the 
background ; they are only moderately divaricating at apex, and have each 
a very faint trace of two dorsal costules.
