Bluish-black ; head, antennae, the anterior and intermediate 
legs, fulvous. 
Head rugose punctate, the vertex with a black spot. Thorax 
with middle portion strongly raised, the elevation bounded laterally 
by a deep groove, posterior portion of the elevation with a high 
transverse ridge which extends downwards at the sides and is 
preceded by another less highly raised ridge, back of the raised 
portion compressed and forms a ridge down the middle to the base ; 
entire surface rugosely punctured. Scutellum twice as broad as 
long. Elytra constricted at middle, with the following tubercles : — 
one at middle of base, followed by an oblique ridge from shoulders 
to suture, ending near latter place with a short transverse ridge, 
two short longitudinal ridges at sides near apex, preceded by three 
small tubercles on the inner disc, all more or less connected ; 
interstices strongly punctured. Pygidium closely punctured, with 
a central longitudinal ridge. Beneath deeply foveolate punctate ; 
posterior legs black, mottled with fulvous. Prosternum strongly 
narrowed posteriorly.

Distinguished principally by the two ridges of the thorax that 
run down the sides, the posterior of the two are joined posteriorly 
and form a highly raised transverse ridge ; also the general coloration 
is bluish-black. The antennae are unfortunately wanting in the 
type and only specimen that is available for examination,
