EURIPUS FULGURALIS, Matsumura. 

 By a. E. Wileman, F.E.S. 



The type of this species, which is in the Taiho Ku Museum, 

 North Formosa, was taken by Mr. Kikuchi at Hokuzancho, 

 Horisha, Nantocho, Formosa, in May, 1908. It seems to be 

 closely allied to Euripus fimebris, Leech (Butt. China, Japan, 

 and Corea, p. 150, pi. xvi. fig. 1), judging from a coloured draw- 

 ing of the type kindly made for me by Mr. Kawa Kami, Director 

 of the Taiho Ku Museum. The discal cell of the fore wings has 

 two rather wide transverse crimson bars, instead of a longitudinal 

 crimson streak as in E.fanebris; and there is a narrow inter- 

 rupted outer-marginal crimson band on the hind wings, becoming 

 obscure towards the costa. On the under side of fore wings the 

 crimson bars are placed as on the upper side, but they are some- 

 what narrower, and the first is irregular ; there are no bluish 

 marks in the cell or between the veins; on the basal area of the 

 hind wing are six crimson spots, two of these are bar-like and 

 placed in the cell, two others are above the cell and more or less 

 in line with a confluent basal pair ; the outer marginal crimson 

 band is broader than on the upper side, more macular, and 

 extended along the abdominal margin almost to the base of the 

 wing. Expanse 86 millim.
