11. Platysoma doriae, n. sp. 



Oblongo-ovatum, subdepression, nitidum; fronte tenue impressa, 

 stria recta; pronoto stria laterali integra; elytris striis 1-3 integris 

 4-5 valde abbreviatisi suturali nulla; pygidio grosse punctato et mar-

This species is extremely like atratum Er., but it is smaller, 

 the 4-5 elytral striae are more distinct , of equal length and 

 terminate in the middle of the dorsal region. The pygidium is 

 more triangular with a smooth slightly raised margin behind. 



Four examples have been taken at Bhamò , Birmania in 

 August 1885.

This species is less parallel than pluviale Mars., but the con- 

 vexity of the dorsal region is similar in both species. The 

 thorax agrees with odiosum Mars, in form except that it is less
