Lcpidoptera of the Altai Mountains. 829 



Antennae ; shaft black ringed with white, club black on the iipperside, 

 white at tip. 



Expanse 21-26 mm. 



Described from 18 males. I did not obtain the female. 



L. melanops, its nearest European ally, has the upper- 

 side purplish-blue, the spots in cells 2 and 6 on the hind- 

 wing below placed at the basal third of those cells, and 

 the fringes white with a dark median line. 



In the tint of the upper side L. argali resembles more 

 nearly the North American Z. couperii, Grote, and L. 

 lygdamas, Dbldy., but both these species have one or 

 more spots in cell la on the fore-wing below, the spot in 

 cell 6 on the hind-wing below standing at the basal third 

 of that cell, and the basal half of the fringes whitish. 



70. L. avion, var. cyanecula, Ev. 



I found this only in the Lower Bashkaus Valley at the 

 south of Lake Teletskoi, where it was fresh at the end of 

 July. Berezowsky also found it at Ongodai. The speci- 

 mens are very variable in size, but may be distinguished 

 like those I have from Irkut, from Turkestan, and from 

 Amdo by the much greater average extension, and bright- 

 ness of the blue at base of hind-wings below. This is 

 found to some extent in arion, especially from southern 

 localities, such as the Pyrenees and Armenia, but never (in 

 my specimens) extends to the margin. The var. caucasica 

 seems too inconstant to bear a varietal name, but in the 

 var. uralcnsis, Gr.-Gr., of which six pairs are now in my 

 collection, both sexes are much darker and more uniform 

 in colour than in Western Europe, and have the underside 

 as in arion and not as in cyanecula. 



{L. areas, Rott.) 



Recorded by Kindermanu but not seen by me. 



71. L. euphcmus, Hb. 



A few specimens in the Bija Valley at the beginning of 

 August. Ruckbeil also got it at Kenderlik. The speci- 

 mens do not differ from European ones. 



72. L. rhymnus, Ev. 



This is recorded by Lederer as taken by Kindermann.
