/y/.s'f of the Phytophagous Colkoptera collected in Assam hj/ 

 A. 11 '. Chennell, Esq., ir/'fli notes (tiid descrlptiovs of tlie 

 iineharaeterized Genera and Species ; by Joseph S. Balv, 

 F.L.S. 



The insects bi-ought over l)y IMr. Chennell are all large or of 

 medium size, the smaller species having apparently been over- 

 lookel or neglected ; tlnis Cri/ptoeephalus, Ilispa proper, and the 

 smaller genera o£ Enmolpidc nnd Ilaltirina- (known to be spread 

 over the whole Indian continent), are nnrepresented. The 

 collection as it stands includes a great number of Asiatic 

 forms, and probably contains the great majority of the most 

 common and salient Assamese species. Many of the larger 

 kinds have been previously described from various parts of 

 India, by Hope, Eedtenbacher and others ; amongst the most 

 noticeable must be mentioned the genus Pentamesa, recently 

 chai'acterized by Von Harold, and also a specimen (unfortu- 

 nately very imperfect) of the rare genus Alacrispa. 



The new forms include several striking genera and species of 

 Gallerucince, many of the latter remarkable for the peculiai- 

 sculpture of the lower face in the $ sex ; the occurence of the 

 genus Entomoscelis for the first time in India is also worthy of 

 note.
