the different disposition of colours, differs constantly from M. angulatus in the sides of 
the thorax being armed | with a 2 very distinct conical tubercle instead of being simply

The lateral tubercles of the thorax are long and pointed; and the elytra are 
separately rounded at the apex; the scutellum is.red. The single example is a female, 
and possibly an extreme variety of M. angulatus.

This beautiful little species offers many peculiarities, but is undoubtedly congeneric 
with Metaleptus. The form and proportions of the antennal joints, shape of the sterna, 
head, and palpi, and the proportions of the legs and tarsi offer no difference worthy 
of note. The chief divergent features reside in the thorax and elytra,—the former 
being relatively narrower and longer, with very uneven convex surface and a central 
short ridge; the latter having vertical epipleure. The red colour of the head, 
thorax, and base of the elytra is very bright and silky under the lens, but opaque, owing 
to the closeness of the alveolated sculpture. The four black spots of the thorax (two 
obliquely placed on each side of the disk) are clothed with long black hairs, the 
central ridge remaining red. The scutellum is moderately elongated, little more so 
than in WU. angulatus. The basal red part of the elytra is bounded very obliquely 
behind, the line commencing on the suture, not far from the scutellum, and terminating 
on the sides at nearly two thirds the length of the elytra, a narrow sutural border at 
the base and a humeral spot remaining black. ‘The legs are very long, the hind 
thighs projecting much beyond the apex of the body, linear and briefly bidentate at the 
tip; the hind tibie are flexuous and rufous towards the tip; the hind tarsi are of the 
same elongated proportions, the lobes of the third joint narrow, and the soles densely 
hairy.
