nothing new — and some further locaUties. The start was 

 made much earher than in 1921, which accounts for the 

 interesting capture of Parnassius hvnnyngtoni again, at 

 the end of April ; but only a single specimen was obtained, 

 unfortunately. The bulk of the collection comes from the 

 comparatively low-lying valley of the Arun River, at 

 altitudes of 11,000-12,000 ft.; nothing was taken above 

 17,000 ft. on this occasion. 



The species have been numbered as in the List of the 

 1921 Collection. An asterisk indicates that the species 

 was not obtained in 1921. The letters (TV.) and (L.) 

 indicate the captures made by Major Norton and Dr. 

 Longstaff respectively,
