a yellowish colour; in a male from Burma, in my own collection, the two posterior 

 spots are wanting, and the sijecimen approaches thus certain males of castor very 

 much. 



The female of Mr. Grose Smi^h has on the forewiugs a complete series of sub- 

 marginal spots, of which the anterior ones are enlarged ; and on the hindwings it has 

 a discal series of spots of the same size as they are found in certain females of castor 

 from Assam. A Burmese female iu my collection has only a few small submarginal 

 >pDts on the forewings in the anal region, and the discal macular band of the hind- 

 wings consists only of six spots, of which the tirst, fifth, and sixth are very small. 



The male and female in my collection here referred to are doubtless mehala, as 

 they were obtained in Burma, and prove that the large submarginal spots of the fore- 

 wings in the type-specimen of the female sex are merely due to individual aberration. 

 To a certain degree mehala stands intermediate between castor and mahadeva, but 

 the complete series of intergraduates between castor and mahadeva being still 

 wanting, mahadeva must stand as a distinct species.

Sexes almost the same, but the female paler brown than the male. 



The spots of the discal macular band of the hindwings are short, and all nearlv of 

 the .same size. 



The female specimen from Eastern Bengal, which ^loore (I.e.) supposed to be 

 the female oi mahadeva, is most probably a, female of P. castor mehala, or belongs to 

 P. castor itself.
