40 Mr. Waterhouse’s Descriptions of 
suture; these lines do not quite extend to the apex of the elytra, 
but near this part they suddenly diverge: on the sides of the 
abdomen above are four yellow spots, and on the terminal segment 
there is one largish round spot of the same colour. There is, 
moreover, a patch of yellow on each side of the prothorax beneath, 
and the remaining parts of the body beneath present six largish 
transverse spots on each side. The femora are black, excepting 
at the apex, and on the upper surface of the apical half, where 
they are of the same reddish colour as the tibia and tarsi, and, I 
may add, the tip of the clypeus, the antennz and palpi.

This species is remarkable for its uniform bluish black colour ; 
it is rather larger than the Macronota Diardii of MM. Gory and 
Percheron’s Monograph, the head is rather shorter and the clypeus 
is wider—broadest in front, where it is not very deeply emargi- 
nated; the upper surface is thickly punctured: the thorax is 
narrower than in M. Diardii, the lateral margins are nearly parallel, 
it being but slightly broader behind than in the middle, and on 
the fore part it becomes somewhat suddenly contracted; the 
posterior angles are acute, and the hinder margin is produced in 
the middle in about the same degree as in M. Diardii; the central 
portion is but slightly depressed, and, unless with a powerful lens, 
no punctures are visible; on the lateral margins, however, there 
are distinct confluent punctures: the elytra are broader than in 
M. Diardii, less attenuated posteriorly, and suddenly contracted 
behind the shoulders, as in that species; the shoulders are very 
prominent, and in the region of the scutellum the elytra are much 
depressed; towards the outer margins are some faint punctures 
and rugee, and the other parts are smooth—at least, but few very 
minute punctures are visible: the scutellum is much larger than 
in M. Diardii, and concave in front: the body beneath is smooth ; 
the anterior tibize are broader than in the species just mentioned, 
and are tridentate externally.
