550 L. de Nice vi lie — Little-Known Butterflies from the [No. 3, 



7. Calinaga cercyon, n. sp., Plate II, Fig. 9, 3 . 



Habitat : The road between Ta-Tsien-Lou and Mou-Pin, and the 

 neighbourhood of Ta-Tsien-Lou, Western China (May, 1895). 



Expanse : <5\ 3 2 inches. 



Description : Male. Allied to G. davidis, Oberthiir, from Moupin, 

 Kouy-Tcheou, Tse-Kou, Ta-Tsien-Lou, Oaa-Se, Yu-Tong, and Kitchang- 

 Kou (Oberthiir), Wa-ssu-kow, and Chow-pin-sa, Western China, and 

 Chang-yang, Central China (Leech), differing therefrom on both surfaces 

 in the ground-colour of both wings being pale straw-yellow instead of 

 pale greenish-gray, and all the markings clear and unsullied, in 

 C. davidis many of them are sullied with dusky scales, this is parti- 

 cularly noticeable in the discoidal cell of the forewing which has no 

 dusky irrorations whatever except a very small outwardly oblique 

 blackish bar beyond the middle ; the pale streaks beyond the cell at the 

 base of the median interspaces, and the very large one in the submedian 

 interspace similarly have no dusky irrorations whatever ; the outwardly- 

 obliquely-placed discal series of spots from the costa to the third 

 median nervule, and the submarginal series of seven rounded spots are 

 also considerably larger. In the hindwing the discoidal cell has no 

 markings whatever, in 0. davidis there is usually a narrow outwardly 

 bifurcated dusky streak, and the cell is always heavily bordered by 

 dusky scales ; all the spots on the disc are also much larger in the 

 present species than they are in G. davidis ; the submedian interspace 

 also is at the base entirely free of dusky irrorations, while in C. davidis 

 the anterior half between the internervular fold and the median 

 nervure and first median nervule is dusky. It differs from G. buddha, 

 Moore, in the ground-colour being pale straw-yellow instead of chalky- 

 white, all the markings larger, especially those on the hindwing, the 

 discoidal cell of the forewing being free of dusky irrorations, in 

 G. buddha it is as dusky as in G. davidis, and it is also a much smaller 

 insect. 



M. Oberthiir says that his original type specimen of G. davidis was 

 a male, but from the figure I should say that it must certainly be a female. 

 Mr. Leech in " The Butterflies of China, Japan, and Corea " has beauti- 

 fully figured an undoubted male on plate xx, fig. 1. He notes on 

 page 119 that C. davidis has two forms, the one from Moupin, Wa-ssu- 

 kow and Chow-pin-sa in Western China being typical, while the one 

 from Chang-yang in Central China, where it is common and " is the 

 sole representative of the species, but also occurs sparingly in Western 

 China, is greyish with the whitish markings well defined ; the streaks 

 and spots are often confluent, giving the appearance of a whitish insect 

 with greyish marginal border and blackish venation." This description
