List of the PiiYTOPiiAGOus Colkoptera collected in Assam by 

 A. W. Chennell, Esfj., with notes and descriptions of tl,e 

 uncharacterized Genera and Species ; by JosKrii S. Baly, 

 F.L.S. 



The insects brought over by Mr. Chennell are all large or of 

 medium size, the smaller species having apparently been over- 

 looked or neglected ; thus Cryptocephalus, Hispa proper, and the 

 smaller genera of Eumolpidce and Halticina; (known to be spread 

 over the whole Indian continent), are unre])resented. The 

 collection as it stands iuchides 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, Redtenbacher and others ; amongst the most 

 noticeable must be mentioned the genus Pentamcsa, recently 

 characterized by Von Harold, and also a specimen (unfortu- 

 nately very imperfect) of the rare genus Macrispa. 



The new forms include several striking genera and species of 

 Gallerucince, majiiy of the latter remarkable for the peculiar 

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



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

 note.
