138 Dr. G. B. Longstaff's Notes on the Butterflies 



the pouches on the hind-wings of the male, but more 

 observations are needed. 



In the case of Limnas genutia, Tirumala limniace, 

 Pararge shalcra, and Colias nilgiriensis the existence of 

 scents was suspected, but the results were ambiguous. 



(6) The observations of Wood Mason were confirmed 

 in Gatopsilia pyranthe and G. pomona. The tufts on the 

 wings of the males gave out on stroking a scent that may 

 be compared to jasmine, though I think it more like 

 Polianthes tuberosa. 



Seasonal Forms. 



With a view to seeing what light, if any, my fragmentary 

 observations might throw upon this puzzling subject, I 

 have adopted the following method : 



In the Register, or Index, of my captures I noted to 

 every Pierine Dr. Dixey's estimate of its seasonal character, 

 and then made my own (far less weighty) estimates of the 

 seasonal characters of the genera Precis, Melanitis, Mycalesis, 

 and Ypkthima, and then analyzed the results for localities, 

 or groups of localities. The seasonal characteristics were 

 classed under the following five heads : — 



(1) Wet-season form, including " wet," " very wet," and 



"extreme wet." 



(2) Somewhat wet form, including "intermediate in- 



clining to wet." 



(3) Intermediate form. 



(4) Somewhat dry form, including " intermediate in- 



clining to dry." 



(5) Dry, including " very dry " and " extreme dry." 



Without prejudice, and for the purpose of this grouping 

 only, I took Gatopsilia gnoma to represent the dry-season 

 form of C. pyranthe, and in like manner Gatopsilia catilla 

 and pomona to be dry-season forms corresponding to a wet- 

 season form G. crocale. 



It must be borne in mind that such a classification is 

 necessarily very vague, for while the extreme forms are 

 easy to place it is most difficult to assess the numerous 

 intermediate specimens.
