As remarked above (p. 17), the genus Synerya, Weise, is not in- 

 cluded among the genera of Indian Chrysomelin^ in this volume. 

 The reason for this omission is as follows. Weise gave the 

 following diagnostic characters of Synerya (Arch. Naturg. lxvi, 1, 

 1900, p. 283) : — The second segment of the maxillary palp is not 

 thickened, and on the underside of it there is a long excavation 

 for the reception of the next segment ; the last segment is 

 rotundate and emarginate at the apex. The posterior angles of 

 the prothorax are simply marginate. The epipleura of the 

 elytra towards the apex are marginate and without hairs. The 

 mesosteniura at the anterior margin is fairly thickened and 

 subangiilate. The metasternum is anteriorly broadly thickened. 



At the time of founding the genus Weise remarked that 

 the species for which he erected it, namely the East Asiatic 

 Chrysolina bella, Jac, was wrongly supposed to be the same as
