often very difficult to say to which of these species certain specimens should 

 be referred. With regard to var. insiilaris described above, Dr. Staudinger 

 agrees with me that it is a form of L. argus, and informs me that he has 

 never previously seen such pale specimens. 



Distribution. Europe, Asia Minor, Armenia, Amurland, Japan, Corea, and 

 1 N. China. 



Lycsena iburiensis. 



Lyccena iburiensis, Butler, Proc. Zool. Soc. Load. 1881, p. 852; Waterhouse, Aid 

 Identif. Ins. pi. 108 (1882). 



" Allied to L. argus, but more nearly of the size and colour above of L. lycormas. Pale silvery blue 

 with brown veins and broad smoky-brown external borders ; fringe very narrow and snow- 

 white : secondaries with broad brown costal area ; body above rather darker than the wings. 

 Under surface chalky bluish white ; the base, especially in the secondaries, suffused with pale 

 bluish green ; black spots arranged as in L. argus, but large and intensely black ; the orange 

 lunules wanting in the marginal ocelloid spots of the primaries, paler in those of the 

 secondaries ; no metallic pupils to the black spots of the secondaries ; pectus bluish. 

 Expanse of wings 1 inch 5 lines. 



" Iburi, Hokkaido [Yesso], July. Coll. M. Fenton." {Butler, I. c.) 



Only one specimen of this species appears to be known; this was in 

 Mr. Fenton's collection, and is figured in 'Aid.' As I have not seen the type 

 I am unable to say anything postively about its being a valid species or not, 

 but the figure seems to represent an insect specifically distinct from either 

 L. argus or L. cegon. In the description of this species the fringes are stated 

 to be snow-white, but in the figure the fringes are chequered with black and 

 white on the upper surface, but are entirely omitted in the drawing of the 

 under surface. 



Lycaena aegina. (Plate XXXI. fig. 11, 6 .) 



Lyccena eegina, Grrum-Grshimailo, Horse Ross. 1891, p. 451. 



" Alis S supra violaceis tenuissime nigro marginatis ciliis albis ; 5 fuscis, ssepe violaceo atomatis, 



posticis punctis submarginalibus nigris ut in Lyccena cegon superpositis maculis rufo-fulvis, 



ciliis albis, fusco-interruptis. 

 " Subtus alis c? anticis cinerascentibus, posticis albis ; fascia omnium lata, rubescenti-aurantiaca, 



maculis nigris albo tenuissime circumdatis et ut in Lyccena cegon dispositis, marginalibus 



posticarum cseruleo squamatis ; 5 alis fuscescenti-albis. 

 " 2 14-15 mm. 



" Haec species, in systemate hujus generis inter Lyccenas cegon et argus ponenda, in Thian-schan 

 orientali, in montibus Boro-Choro reperta est." (Gr.-Gr. I.e.)
