Pai'uassius iinperator (aiigustus, Friilist.) ? in lit. 



A fiesli pair from Mr. Rothschild coUected at Kham- 

 bajong, about 40 miles north of the Sikkim frontier, in July 

 19US, at an elevation of about 15000 feet, do not diifer in any 

 way worth mentioning from those from Ta-chien-lo in W. China, 

 though the outer bands of the hindwing above are more 

 distinct. The pouch of the female, though slightly damaged, 

 api)ears to be of precisely similar structure. 



Paruassius simo var. ? (P. acconus, Frühst. Iris 1903 

 p. 43.) 



A fresh male sent by Mr. Rothschild, which agrees witli 

 the figure made by Col. Fawcett from a specimen taken at 

 17 — 19 000 feet in Native Sikkim, is very like var. Simu- 

 lator, Stgr. from the Thianshan mountains; except that it 

 has two bright red ocelli on the hindwing in the usual position, 

 which are black in s i m o n i u s and in the typical specimens 

 of simo, a character of no specific importance in my 

 opinion. I am, however, unable without seeing a female to 

 say for certain whether this male is a form of simo, or of 

 a c c , of which I received one specimen from a native 

 collector on the Sikkim frontier as long ago as 1881, which 

 is further mentioned in my paper on the genus Parnassius in 

 P. Z. S 1886 p. 35. Fruhstorfer says that the pouch of the 

 female of his acconus is „nur ein wurmförmiges An- 

 hängsel, einen dünnen Schlauch ähnlich wie ihn s i m o n i u s 

 Stgr. trägt." This alone would be amply sufficient to shew 

 that it has more affinity with simo than with a c c o , whose 

 pouch is one of the most distinct and peculiar in the whole 

 genus. C. F. Elwes P. Z. S. 1886. Plate. 



Paruassius delphius var = P. delphius lampidius. nov. 

 subsp. Frühst. Iris 1903 p. 44. 



A Single female sent me by Mr. Rothschild is probably 

 the same as a female of which a dravving was made by Col. 

 Fawcett from a specimen taken with the last. It appears to 

 be a very dwarfed specimen of a form of the wide-ranging 

 and variable P. delphius, coming nearest to var. s t a u - 

 d i n g e r i Bang-Haas, but much smaller. The pouch being 

 damaged I cannot be certain whether it is the same, but it 

 has the general form of the very peculiar-shaped appendage 

 common to all the varieties of this species.
