The comparatively elongate form of this insect, with elytra by 
measurement distinctly (by about 4, of their width) longer than 
together wide, together with the comparatively sparse punctura- 
tion of its elytra, will distinguish it from its allies. The markings 
on the elytra of my unique example are very distinctive, but it 
is doubtful whether they are constant ; they consist of a number 
of wide dark vittz (on which the punctures are nearly black) 
and may be thus described : from a point on the suture slightly 
in front of the apex five vitte diverge forwards (7.e., towards the 
front of the elytra)—one up the suture, one close to the lateral 
margin, and three at equal intervals between ; the sutural vitta 
is continuous to near the scutellum, a little behind which it 
ceases ; the others extend to the base, but the second (counting 
from the suture) is widely interrupted in the middle; the external 
three all become very faint about the middle and then becoming 
well defined again coalesce in a large blotch on and around the 
humeral callus. The width of these vittee is such that they are 
wider than the intervals between them; the first, third, and 
fourth are the widest. 
Australia ; exact habitat unknown, but it is probably in 8.W. 
Australia.
