LYCJENA. 339 



anterior spots are barely indicated, the posterior three or four 

 obsolescent but traceable. Hind wing : pale metallic green ; a 

 broad terminal edging grey ; the ground-colour bounded outwardly 

 by an obscure series of dusky spots that are suffused with metallic 

 green. Antennas, head, thorax and abdomen dark brown, shafts 

 of the antennas ringed with white ; beneath : palpi, thorax and 

 abdomen white. 



Exp. <$ 34 mm. (1-34"). 



Hub. Tibet: Gyantze ; Sikhim : Chumbi Valley, Phari. 



This form, collected by Capt. Walton, I.M.S., during the late 

 Tibet Expedition, is very close to, even if it can be considered at all 

 distinct from L. felicis, Oberthiir, which was also abundant at 

 Gyantze. I have been quite unable to identify and separate the 

 2 from the females of felicis. The chief points of difference 

 in the d 1 are " the dark leaden grey instead of greyish-brown 

 colour above" and the obsolescence of the terminal markings.

c? $ . Eyes hairy, c? . Upper side : purplish blue, with a rich 

 satiny lustre in certain lights. JFore and hind wings : purer darker- 

 blue at base, with anticiliary, black, slender lines on both wings. 

 In some specimens this line on the hind wing is bordered by a 

 row of black spots in the interspaces, some of which latter become 

 obsolescent posteriorly. Cilia white. Underside : pale opaque 

 grey ; bases of both fore and hind wings and the dorsal margin 

 of the latter wing broadly and diffusely irrorated with greenish- 

 blue scales. Fore wing : a spot in middle of cell, a spot below it 

 in interspace 2, a transverse spot on the discocellulars and a trans- 

 verse bisinuate discal series of rounded spots black, each encircled 

 narrowly with white ; beyond these a transverse slightly curved 

 series of dusky lunules and a slender dark anticiliary line, the 

 portions of the ground-colour enclosed between them at the apices 

 of the interspaces slightly paler, each interspace v,ith a dusky 

 black spot. Hind wing : a subbasal transverse series of four spots, 

 a strongly curved transverse discal series of seven smaller spots, a 

 transverse postdiscal series of eight slender lunules and a sub- 

 terminal series of seven spots, black ; the subbasal and discal spots 

 narrowly encircled with white, the postdiscal series of lunules 

 outwardly bordered with pale reddish brown ; finally, a dusky
