The Fauna gives North Bengal and the Bor Ghat. 



I confess to doubt as to these being distinct and I lay no stress 

 on their occurrence. In view of the remarkable colour changes of 

 this insect at the last moult^ I cannot believe they are distinct. I 

 have however followed Distant, who presumably has clearly dis- 

 tinct series. 



The insect is abundant at Pusa. 



88. Serinetha abdominalis , Fabr. 



Pusa. vi-07. 

 Kanara. viii-07.

The Fauna records Bombay, Calcutta, Assam, Ceylon, Tenas- 

 serim. 



S. augur, Fabr., we have not found. 



This family offers little but the marked paucity of large forms 

 already commented on. Its members here are largely Burmese or 

 Malayan, and our fauna owes little to neighbouring sub- tropical 

 areas; rather our species may be those of the Gangetic Plain, East, 

 able to stand the greater dryness and heat of our area and migrated 

 in from the East.
