I have received six female specimens from Chang-yang, Central China, 
where they were taken in June and July. 
Cyaniris argiolus.

Lyccena ladon, var. ?, Menetries, Cat. Lep. Mus. Petr. pt. ii. p. 1.24, pi. x. fig. 5 (1857). 
Lyccena ladonides, de I'Orza, L^p. Jap. p. 20 (1867). 
Lyccena levetti, Butler, Ann. & Mag. Nat. Hist. (5) xi. p. Ill (1883). 
" Expands 0-80 to 1'40 inch. Fringes of the fore ^-ings black and white ; those of the hind wings 
white. Wings of the male clear, light blue ; fore wings with a ver}- narrow black hind 
marginal border. The female has the outer halt of the costa and all the hind margin of the 
fore wings broadly brownish black; the hind wings are similarly brownish black on the costa; 
sometimes the hind margin is also dark brown, and always has a row of black dots. Under- 
side bluish grey ; fore wings with an elongated black discoidal spot, and a row of black spots 
running parallel to the hind margin ; hind wings blue at the base, with an irregular central 
row, an elongated discoidal and two basal spots. The spots in this species are all black, 
without white rings. 
" Larva. Dark greenish grey, with a dark green dorsal line. Feeds on the flowers of Uex, Hedera, 
and Bhamnus in June and again in the autumn." {Lang, I. c.) 
A very complete life-history of this species will be found in Buckler's 
'Larvge of British Butterflies and Moths,' i. pp. 94-100. In addition to the 
food-plants referred to by Dr. Lang, Cornus sanxjuinea has been mentioned. 
Menetries seems to have considered that the Japanese form of L. argiolus 
was probably a form of L. ladon, Cramer, but de I'Orza having examined 
the true L. ladon, Avhich is a species from the Cape of Good Hope, in 
Boisduval's collection, came to the conclusion that Cramer's species was very 
distinct from the Japanese insect, and therefore he gave the latter the name 
of L. ladonides. 
Mr. Butler has described Corean L. argiolus under the name of L. levetti, 
of which the following is the original description : — 
" AUied to L. argiolus and L. ladonides. From the former the male differs in the broader and less 
sharply defined blackish border to the outer margins of the wings and the greyer tint of the 
under surface ; the female differs in its darker tint and broad external blackish border to the 
secondaries ; the costal border is also broader, so that the silvery-blue area is confined to a 
triangular abdominal patch ; below, the white is a trifle less pure, and the submarginal 
luuules a little better defined than in L. argiolus. From L. ladonides the male is readily 
distinguished by its Hlacine instead of cserulean colour, and the female by its gre}'er tint 
throughout, and its more decided broad blackish external border to secondaries : both sexes
