We received this with the preceding. It is principally 
distinguished by the red arched ridge of the scutellum on 
each side of which there is a longitudinal wavy line, nearly 
in the form of an S, which towards the end is interrupted, 
and then terminates in a short straight line. The dilated 
sides of the scutellum are white. There is also a faint 
white spot on the posterior thighs.

This was also sent us by the Rev. Mr. Kirby. It is one 
of that order in which the scutellum is arched and very 
much elevated. The body is black. Antenna: fulvous, 
black at the end. Scutellum the length of the body. Dorsal 
carina obscurely clouded with white. The margin of the 
scutellum towards the end is pale. Legs pale at the base. 
Posterior thighs with an irregular whitish snot.
