Bengal: Chota Nagpur (Cardon). 



The species in some respects approaches Platyrhopalopsis mellyi 

 and picteti, but is much smaller and differently coloured, and the 

 pronotum is subcordiform and not elliptical as in these species.

xxv, 1904, p. 20. 



Kufo-castaneous, rather shining, with a single large triangular 

 dark patch on the side of each elytron, the base of which almost 

 rests on the margins ; head not, or scarcely channelled in front ; 

 antennae with the first joint large, subquadrate, produced internally 

 into a strong blunt tooth, the second joint forming a large, con- 

 vex, shining, almost circular club, with even margins, which is 

 impressed just before the base where there is a wide incision, 

 one side of which is formed by a long sharp tooth ; pronotum at 

 least as long as broad and not very abruptly contracted behind 

 the middle, very finely sculptured ; elytra oblong, extremely 

 finely sculptured, subparallel-sided, slightly widened behind ; 

 tibiae dilated and compressed, and ending in a sharp point 

 externally at the apex. 



Length 6-7 \ millim. 



Centhal India : Niraach. 



This species may at once be known from P. denticornis (apart 

 from colour, which is often variable in the different species) by 

 the wider incision and much longer and sharper tooth of the club 

 of the antennae, and the less transverse pronotum ; the sculpture 

 on the latter is finer, and the contraction behind the middle much 

 less abrupt. 



Var. acutidens, Westw. 



Larger, broader, and less parallel-sided than the type-form, with 

 the tooth at the base of the club of the antennae longer, sharper, 

 and almost falcate. 



Length 7-8 millim. 



Nepal. 



Yar. major, Wasm. 



Larger than the type, of a bright castaneous colour, with a 

 dark transverse band on the elytra, which is interrupted at the 

 suture. 



Length 8{ y -9 millim.
