I have received six female specimens from Chang-yaug, Central China, 

 where they were taken in June and July.

" Expands 0-80 to 1-40 iiich. Fringes of the fore wings black and white ; those of the hind wings 

 white. Wings of the male clear, light blue ; fore wings with a very narrow black hind 

 marginal border. The female has the outer half 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 grej' ; 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 Ilex,Hedera, 

 and Mhamnus in June and again in the autumn." (Lang, I. c.) 



A very complete life-history of this species will be found in Buckler's 

 'Larvae of Britisli Butterflies and Moths,' i. pp. 94-100, In addition to the 

 food-j)lants referred to by Dr. Lang, Cornus sanf/uinea has been mentioned. 



Menetries seems to have considered that the Japanese form of L. argiolus 

 was probably a foi in of L. ladon, Cramer, but de I'Orza having examined 

 the true L. ladon, which 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 tlie Japanese insect, and therefore he gave the latter the name 

 of L. ladonides. 



Mr. Butler has described Corcan L. argiolus under the name of L. levetti, 

 (if wliicli the following is the original description : — 



" Allied to L. aryiolus and L. huhmidcs. From tlic former tlic male diil'ersin the broader and loss 

 Hhnqjly defined l)bickisli border to the outer niiirgins of llie wings and the greyer tint of the 

 undi-r Htirfacc ; the female differs in its darker tint and 1)road external blackish border to the 

 BccoiidnricH ; tho costal border is also broader, so that the silveiy-blue area is confined to a 

 trian(,'ul(ir abdominal patch ; below, tho white is n, trifle less juire, and the submarginal 

 lun\ilfH n little better defined tlian in L. arrjiohix. Yrom Jj. Jadonides the malo is readily

 throughout, and iis more decided broad blackish external border to secondaries; both se.vos
