32 MR. H. J. ELWES ON THE GENUS PARNASSIUS. [Jan. 19, 



the fore wing and four on the hind wing), together with the four basal 

 ones, are almost always present, corresponding to those on the upper 

 surface, iu which the red is often absent. The pattern of the under- 

 side is very characteristic, and would, I think, alone be enough to 

 distinguish all the specimens from Lahoul from any other species. 



The antennae are decidedly blacker than in any of the allied 

 forms, and though ringed faintly with whitish in some specimens, 

 are never so much so as in all the forms of P. delius, or in P. acttus, 

 discobolus, and jacquemonti. They vary so little in 100 specimens 

 that I have examined, that should series from other localities besides 

 Lahoul be found to present the same constant dift'erences in antennse 

 and markings from P. actius that these do, I think it might be allowed 

 specific rank with as much or more justice as other so-called species 

 of Parnassius. Of the habits we know but little. It bpgins to fly 

 about the middle of July or earlier, according to the season and ele- 

 vation, and continues to be found in a fresh condition till the end of 

 August. 



1 think that the figures of Blanchard and that given by Oberthiir, 

 which is taken from a male specimen from Boisduval's collection, 

 supposed by him to be the type of Boisduval's description, represent 

 this species and not the true P. jacquemonti. 



Whether this species ever occurs in the same region with that 

 insect I am not at })resent able to say ; but 1 think it does not occur 

 at so high an elevation, and I doubt whether it extends to Ladak. 

 I have never seen specimens from any locality east of the Ganges 

 valley in Upper Gurwhal, where Mr. Duthie found it at elevations of 

 about 1 1,000-13,000 feet near Phuladaru. 



P. HONRATHI. 



Parnassius honrathi, Stgr. Berl. ent. Zeit. xxvi. 1882, p. 161, 

 t. i. figs. 4, 5, 5 a. 



P. corybas, Ersch. Fedtschenko's Reise, p. 2, t. i. figs. 1, 2 (1874) 

 (nee Fischer). 



This little-known species seems to have been first discovered by 

 Fedtschenko at Kulbasin, near Sangi Djuman, on May 25, and 

 KuU Kalan on June 25, in Zarafshan, about 7000 feet high, but 

 being mistaken by Erschoff, who described the Lepidoptera of the 

 collection, for P. cori/bas of Fischer, remained unknown until Haber- 

 hauer sent from the Hazret Sultan Mountains south of Samarkand a 

 number of specimens (about 20 males and 5 females), which he took 

 at about 6000-7000 feet in July 1881. These were described by Dr. 

 Staudinger, who considers the species quite distinct from P. corijbas 

 of Fischer, which comes from Kamschatka, and is probably only a 

 form of P. delivs. 



It differs from all other Parnassius of this group in having black 

 antennae, black fringes, and black legs and feet ; the clothing of the 

 body beneath is also black. 



The pouch of the female is of the apollo type, though this is not 

 shown eitiier in Erschoff 's or Staudinger's plates ; and Staudinger 

 says that iu one specimen it has a rather produced point.
