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 stronglv 

 narrowed posteriorly. 



Length 3 mm. 



Hub. Southern India : Pondicherry (Coll. Jacoby). 



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.
