HYPERMXESTBA.. 133 



Taead and the thorax anteriorly with long greyish-white hairs ; 

 beneath : the palpi, thorax, legs and basal portion of the abdomen 

 similarly clothed. $ . Differs from the d 1 as follows : -Upperside : 

 all the markings larger and more conspicuous ; an additional large 

 black spot in the middle of interspace 1. Underside: similar 

 to that of the J , but with the additional black spot as noted 

 Above. 



Exp. <$ 52-66 mm. (2-02-2-60"). 



Hab. Baluchistan, within our limits, and northwards through 

 Persia to Turkestan and the western shores of the Caspian Sea. 



The above descriptions are drawn that of the c? from a c? 

 from Baluchistan, type of Moore's Parnassius balucha, which is 

 now in the British Museum ; that of the $ from a specimen in 

 my own collection from Southern Persia. Both belong to the 

 larger form, var. maxima, Grr.-Gr., a series of which from Turkestan 

 is in the British Museum. The difference between this variety and 

 typical Jielios is chiefly one of size, though the markings in typical 

 -helios are possibly duller and smaller, but these characteristics are 

 very variable. 



In the British Museum collection also there is a single prepared 

 specimen of a larva from the Christoph collection, labelled helios. 

 This is 38 mm. in length, cylindrical, of a pale yellowish-white 

 colour, with four longitudinal rows, two medial and one lateral on 

 each side, of rather large yellow spots ; the head is a darker yellow, 

 and each of the succeeding segments bears a transverse series of 

 small black spots, the middle two round and sharply defined, the 

 others irregular, some minute and mere dots, others slightly 

 elongate ; each transverse row ends on either side with a spot 

 -above the spiracles.
