CYANIRIS SEMIARGUS. 271 



fuscous and rather smaller than $ . (8) one $ and one $ , " Arasai, 

 Altai mountains, 6000ft., 1900 (Leder)," the 2 entirely fuscous, same 

 size as $ ; (4) one <? , " Sary Ob, Sarafshan, 7000ft. -9000ft., 1900 

 (Funke)," rather small (30mm.); (5) one $ , " Tian-chan — Yir Madaus, 

 7. vi. '89 (Grum-Grshimailo)," near the last, rather bluer, and slightly 

 narrower border; (6) one $ , " Lajran, Chingob-d., Daiwas (Grum- 

 Grshimailo)," one $ " Tohi-Alai-d., Chingob-d., Daiwas (Grum- 

 Grshimailo)." These two examples have a label " ussuria, Gr.-Gr., 

 MSB." We are not able to trace the name, nor connection between 

 the specimens and the place (Ussuri) apparently indicated. 



y. var. amnrensis, n. var. Semiargus var., Stand., " Rom. Mem.," vi., p. 163 

 (1892) ; Herz, "Rom. Mem.," xi., p. 238 (1898).— Very large in size, 36mm. -38mm. 

 <? of good colour, somewhat variable in width of border ; the nervures suffused, 

 discoidal lunule clearly defined, fringes white. ? uniformly fuscous, fringes 

 white, costal border of forewings also narrowly white. Undersides typically 

 marked, with fairly large ( ? very large) white-ringed spots. Amur — Blagovet- 

 schensk, Sutschan. 



There are in British Museum coll., only three Amurland specimens. 

 These are — (1) <? , labelled " Blag : Amur (Leech coll.);" (2) <? , 

 "Amur. Std., '80 (Elwes coll.);" (3) ?, "Sutschan, east Asia 

 (Domes)." The Blagovestchensk $ is large, with narrow border, the 

 other almost exactly similar, but with a wider border. The £ is a 

 very remarkable specimen. It is unicolorous, of a dark fuscous tint, 

 with almost snow-white fringes, and a narrow white costa to the fore- 

 wings ; the latter are very rounded, and give it a very special appear- 

 ance ; the underside has exceptionally large spots. Chapman 

 has also two Blagovestchensk $ s from the " Lang coll.," both with 

 narrow border, and of quite a bluish-mauve tint. Staudinger says 

 of this form : " According to Menetries, Schrenck found this insect 

 near Borbi, Christoph took it near Kaddefka, Dorries sent it from 

 Askold, and Graeser found it rather rarely near Chabarowka and 

 Pokrofka. My Amurland examples are generally very large, other- 

 wise they agree almost exactly with European specimens." Herz 

 observes (" Lep. from Lena and N. Siberia," Rom. Mem., xi., p. 238) 

 that " specimens were taken from July 13tb-30fch, at Witim and Wilni ; 

 the upperside of the $ s rather brighter blue than specimens " before 

 him " from the Ural, Caucasus, Thian-Shan, and Mongolia. The under- 

 side of both sexes also exhibits a far brighter coloration, and comes, 

 in this respect, near parnassia, Stdgr., only that the blue tinge on the 

 underside is not so strongly expressed." 



5. var. fergana, n. var.— 30mm. -36mm. Almost the same size as var. altaiana. 

 <? slightly brighter in ground colour than of that variety, discoidal lunule obsolete, 

 nervures hardly suffused ; dark marginal borders very narrow ; fringes white. ? 

 of same size as <? , entirely fuscous, with grey or greyish-white fringes. The 

 underside grey in <r , brown-grey in ? ; the spots typical in arrangement, rather 

 small in size, 6 and 7 of forewings tending to obsolescence. Namangan, 

 Bashkaus, etc. 



This is a bright-coloured, narrow-bordered race (whether seasonal 

 or geographical there are not enough data to show). In the British 

 Museum coll., there are — (1) <y , labelled "Namangan, central Asia, 

 ex Staud." ; (2) $ and $ , " Alarsk. fl. Jret, 1894 (Kaschkaroff)," the 

 J very blue, narrow -bordered like the Namangan specimen ; the ? 

 large, fuscous ; (3) $ and £ , " South-east Altai, Bashkaus, 8000ft.- 

 6000ft.," the $ "30. vii. '98," the 2 , "26. vii. '98," the $ of good
