LYCAENA ARION. 313 



in one ? . One of the $ s has a broader dark band on the forewings 

 on the upper side which partially conceals the marginal spots, the 

 other has two basal spots on the upperside forewings the lower of which 

 is joined to the last of the submedian series, the whole series in both 

 being more elongated than in the $ s. On the underside one $ and 

 one 2 are without the basal spot on the forewings. They are of very 

 uniform size the $ s expanding 42 mm., the 2 s 44 mm. 



The shape of the wings is that of Graeser's three specimens described 

 above, which also came from the Amoor district, but the colouring of 

 Herrich-Schaffer's figure is quite different, though not so unlike the 

 colour of var. nariina, which has much the same shaped wings. 



(8) var. tatsienluica, Obth., " Lep. Comp.," iv., p. 328 (1910), vi., pi. cxxvi., 

 figs. 1121,2 (1912). — The j- , above, is entirely blue, without black spots ; the ? is 

 clouded by the blackish tint, and is spotted with black on the upperside of the 

 forewings. Beneath, the hindwings are very broadly covered with a greenish 

 dusting and the usual black spots are very small (Oberthiir). 



Loc. Ta-tsien-Lou (Thibet). 



[The plate shows a bright blue $ , with very narrow black border 

 with slight whitish lunular spots within it, and a small black discoidal 

 spot on the forewing ; the hindwing affords slight traces of spotting 

 within a yet narrower black border ; the underside has large spots on 

 the forewing but is without a basal spot, the green suffusion on the 

 hindwing extends as far as the marginal spots which are more distinct 

 than those on the forewing ; there are three basal spots. The 2 has a 

 broad dark border, blacker towards the edge of the wing, a well-marked 

 black discoidal spot and a series of 5 submedian spots on the forewing, 

 but no spotting on the hindwing; the underside shows a well-spotted 

 forewing, the basal spots, however, being absent on both wings, and 

 the green suffusion only extends to the submedian series, the second 

 and third spots of which (counting from the inner margin) are 

 suppressed. The wings are of the usual avion shape, not long and 

 narrow as in the last two forms. (G.W.)] . 



(e) var. uralensis, [Gr.-Gr. ? M.S.] , Elwes, " Trans. Ent. Soc. Lond.," p. 329 

 (1899). — In the var. uralensis, 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 in cyanecula (Elwes). 



We have been quite unable to trace this name to Grum-Grshimailo, 

 except in MS. Of the six pairs mentioned above, five are now in the 

 Brit. Mus. coll., and from these. we take the final observation quoted 

 above as to the underside to mean that the suffusion does not surpass 

 in extent the more pronounced cases of avion, and that it never reaches 

 the marginal spots as it does in extreme cases in cyanecula. All the 

 ten specimens in the Brit. Mus., seem, however, closer in this respect 

 to the Eastern than to the Western forms. The 3 s are all very lightly 

 spotted on the upperside, in one case only the discoidal is present, and 

 in another case even this is absent ; they are of very dark colouring, 

 approaching the var. unicolor, Horm., but owing, in this case, to the 

 encroachment of the dusky border. The 2 s are well spotted on the 

 forewing on the upperside, but have no spots on the hindwing. On 

 the upperside they are much like some specimens of the var. obscura ; in 

 the obsolescence of the marginal spots on the underside they approach 

 very closely to the following form.
