XVI. — Preliminary List of the Butterflies of Madras. — By Lieut. E. Y. 

 Watson. {Communicated by E. Thurston, Esq.) 



[Received July 9th :— Read 5th November 1890.] 



The following list of Madras Butterflies is compiled from a collec- 

 tion made between March and the middle of August, 1889. The total 

 number of species obtained is only 74 ; but there is no doubt that, if 

 the observations had been extended throughout the entire year, this 

 number would be increased by at least twenty additional ones. For 

 the first three months of this period there was little or no rain ; but 

 from the 1st June till the middle of August the rain, though never 

 very heavy, was more or less continuous, comparatively few days pass- 

 ing without at least a slight shower. It will be noticed that only the 

 typical wet-season forms of Mycalesis mineus, Melanitis leda, and Junonia 

 asterie were met with. Presumably the corresponding dry-season forms 

 would be met with fyom November till February.
