not otherwise have seen. I have prepared and examined 

 over 600 microscopical sHdes from these specimens, a 

 few of which I have photographed in order to show 

 important characters which refer specially to the genus 

 under discussion. 



In placing before you the chief results of my exami- 

 nation, I may confess at the outset that the evidence 

 is incomplete, as in certain cases much more might 

 have been done in investigating the intimate struc- 

 ture of the exoskeleton, particularly in regard to the 

 Pierine genera Baltia, Mesapia and Davidina (which was 

 placed as a Papilionine genus), and which, owing to their 

 rarity, I have been unable to obtain. In our present know- 

 ledge of the genera mentioned, some of the results are 

 confusing, and will, I think, remain so, until a much larger 

 quantity of material is worked out and the results of the 

 comparison of these genera, along perhaps with the 

 investigation of the early stages of their metamorphosis, 

 have been tabulated. 



In dealing with the subject I have thought it advisable 

 to divide my arguments into separate headings : 



The evidence of geographical distribution. 



The evidence of the structure of the q^^ shell. 



The evidence of the structure of the legs. 



The evidence of the structure of the antennae. 



The evidence of the structure of the basal cell of the 

 hind wings. 



The evidence of the general neuration and facies. 



The Evidence of Geographical Distribution. 



The habitat of the genus Calinaga is the Eastern 

 portion of the Himalayan chain {Buddha), Yunnan, 

 Western China and Eastern Thibet {Davtdis), and Upper
