PROCEEDINGS OF THE TIIIItD ENTOMOLOGICAL MEETING 



To satisfactorily settle the status of our Ceylon species and races it 

 will be necessary to examine a large number of allied Indian forms, 

 especially from vSouth India, and I shall be very grateful to any Indian 

 collectors who will send me specimens for dissection. 



In this paper we come again on the question, which arose several 

 times during the discussion of several Lepidopterous peSts during the 

 earlier part of this Meeting, of the separation of superficially-similar 

 forms by means of distinct differences in the male genitalia. The 

 Hesperiadffi form an especially difficult group for the discrimination of 

 species in the ordinary way and we must welcome Mr. Ormiston's work 

 on the separation of the Sinhalese species as a solid contribution to the 

 Subject. I would therefore call your particular attention to his appeal 

 for specimens of Hesperiadre, from Southern India especially, and would 

 ask you to send him for examination any specimens that you can spare, 

 as further comparison of the forms occurring in India and Ceylon cannot 

 but improve our knowledge on this subject.
