extending to the base of the prothorax, with the six apical seg- 

 ments distinctly thickened. Prothorax apparently quadrate, but 

 actually about one millimetre broader than long ; the surface is 

 extremely convex in front, while the transverse depression in 

 front of the base is so shallow that in some aspects it can be 

 hardly recognised ; the transverse depression is bounded on either 

 side by a deeply impressed short longitudinal line ; anterior lateral 

 angles rounded, the posterior angles being also more or less 

 rounded ; base gently sinuate. Scutellum triangular and insignifi- 

 cant. Elytra hardly broader at base than prothorax ; the surface 

 is smooth, flat and punctate-striate, the punctures being strong, 

 but the rows not very regular. Underside : prosternura more or 

 less broad with apex rounded; anterior coxal cavities closed 

 behind ; posterior femora strongly incrassate ; all the tibise are 

 cylindrical, with channels and apical spurs; tarsi with the claw- 

 segment long ; claws divaricate and appendiculate. 

 Range. India. 



This genus differs from the next following genus, Pseudodera, 

 in the form of the antennae, the shallowness of the transverse 

 impression before the base of the prothorax, the fact that the 

 elytra are hardly broader at the base than the prothorax, and 

 the partial irregular it}' of the seriate punctures on the elytra.
