"A fourth form from Ichang, China, which has above a broad, black 

 border and very light yellowish red discal spots, the hindwing being 

 strongly angulate, is considered by Leech to be a form of angulata Moore, 

 while Fruhstorfer treats it together with angulata as a form of bulis Doubl. 

 and Hew. But as I have found in Japan as well as in China at the same 

 place and hour specimens with sharply angulated outer margin to the hind 

 wing and individuals with the hindwing completely rounded, the distinctions 

 in the shape of the wings appear to me to be of doubtful value." 



The following description of Curetis paracuta Niceville is given 

 for convenience of reference: 



Male. — Upperside, both wings may be distinguished from all known 

 species of the genus by having the red areas of a duller colour, ferruginous 

 rather than cupreous, as usual, the extent of the red coloration varies 

 greatly, in some specimens being twice as great as in others. 



Female. — Upperside, both wings differentiated in the same way by the 

 white areas being heavily frosted with bluish scales, the extent of these 

 bluish-white areas being as variable as in the male, and the apex of the 

 forewing also varies in its greater or lesser acumination. All writers on 

 Japanese butterflies have called the species of the genus Curetis occurring 

 there C. acuta Moore, which was originally described from Shanghai in 

 North China and of which the C. truncata of Moore, and the C. angulata 

 of Moore, are in my opinion synonymous. C. acuta occurs from the eastern 

 coast of China (Shanghai and Hongkong) to the Western Himalayas. The 

 female has the wings above with white central areas. The late H. Fryer's 

 figure of the female of the Japanese Curetis is very bad, as it shows the 

 upperside of both wings white instead of bluish white as it is, I believe, 

 invariably. He describes it as "blue." 



C. paracuta appears to be a fairly common species in Japan, Pryer 

 giving four localities for it. Leech, the mountains of Central Japan and I 

 have it from Tokyo and Nikko, besides other places not specified. 



Habitat: Japan. Expanse: d", 2.0 to 2.1; ? 2.0 to 2.2 inches. 



The larva of Curetis paracuta (Plate II, fig. 18) was taken 

 June 4, 1901, at Yoshino, Yamato Province, Honshu, on wistaria, 

 the Japanese name of which is fuji (Kraunhia floribunda Willd.) . 

 It pupated June 6, 1901, and a male imago emerged June 16, 1901. 

 A second larva was taken at Yoshino July 18, 1901. The imago 

 which emerged is no doubt referable to C. paracuta Niceville, 

 which is the Japanese form of the species. 



The transformations of C. acuta have been figured and de- 

 scribed by Nawa. He gives figures of the larva in all its stages, 

 of the pupa, and of the imago, and a general life history. 



Larva. — The following is a description of my larva of C. para- 

 cuta (Plate II, fig. 18) taken from my original figure: Length, 

 29 millimeters. Dark green; head retractile; segment 4 con- 

 siderably dilated laterally and vertically so as to form a decided 

 ridge across the segments ; spiracles brown ocellated with white ; 

 spiracular and subspiracular region paler in color; two semi-
