ASSAM, SYLHET AND CACHAR. 353 



[Common all over Dibrugarh in all the paddy fields, road- 

 side cuttings, and pools of water. — J. R. C] 



It is common throughout every province of British 

 Burmah. 



1008. — Plotus melanogaster, Penn. 



This species seems very scarce in Manipur. There were 

 a few about the Logtak lake, and I saw one in a stream 

 running into the Jhiri river, just inside the Manipur frontier, 

 but these were the only occasions on which I met with it in 

 that State. 



It occurs in both Sylhet and Cachar, but I have no record 

 of its occurrence in Assam. 



It is more or less common in suitable localities throughout 

 every part of British Burmah.
