Pamassius apollo subsp. ? 



This form is very curious, but a single specimen is insufficient to say what 

 it is. 



Forewings similar to merzhacheri . Hindwings with distinct submarginal 

 band of grey-black chevrons, ocelU with large divided white patch, supra-tornal 

 patch red with black edging. Size very small. 



Length of forewing : 41 mm. Expanse : 87 mm. 



Figured by Verity, Rhopal. Palaear. pi. Iviii. f. 6, as moiigolica Stdgr., 

 which it certainly is not, as that is the insect afterwards named by Fruhstorfer 

 tnerdjacheri.

Pamassius apollo subsp. ? 



There appear to be two forms of apollo in the Altai Mountains, one a medium- 

 sized form = a. alpherakyi and a very large form, the present one. It is more 

 than probable that they come from different parts of the range, and eventually 

 the large race will have to be named.
