NEW BUTTERFLIES FROM FORMOSA AND JAPAN. 93 



what similar to those on the same area of the fore wings, but the 

 submarginal Hne is preceded by a black ring and cloud and some 

 blackish spots, and brownish clouding between these and the costa ; 

 the abdominal fold is greyish, and the adjoining interspace is clothed 

 with black and fulvous hairs. Under side of the fore wings fulvous, 

 with black markings as above but smaller, the middle spot on costal 

 area divided into three pai'ts, the largest of these enclosing a pale 

 dot ; two whitish spots on the outer edge of the third costal spot ; 

 the lunules before the marginal line merge into whitish towards the 

 costa. Hind wings silvery white, with a network pattern in black 

 above the cell towards base ; two black spots in the cell ; beyond the 

 middle there are two black, wavy lines, with the space between them 

 filled in with fulvous, and enclosing a black ring in the first and a 

 black spot in the second median interspaces. Expanse, 70 millim. 



One male specimen from Lalachi, June 1st, 1908, 4000 ft. 



Orthomiella rantaizana, sp. nov. 

 Male. Upper side sooty black, the costal half of hind wings 

 purplish with a metallic sheen, but this colour hardly extends to the 

 outer margin. Under side brownish, sprinkled with bluish-grey 

 scales over the discal area, but most in evidence on the basal area of 

 each wing ; on the fore wings there is a spot in the cell, one at the 

 outer end of the cell, and a rather curved, transverse, macular band 

 beyond ; all these markings are but slightly darker than the general 

 colour, and are very indistinct ; the hind wings have two irregular 

 dusky bands, the basal one finely edged outwardly with lilacine ; a 

 series of dusky marks on the outer margin, those nearest the anal 

 angle black and most distinct. Expanse, 27 millim. 



Hah. Formosa. 



Male type from Eantaizan, Formosa, 6000 ft. Two male 



specimens from Eantaizan, May 4th, 1909, and May 14th, 1909. 



This species is near 0. pontis, Elwes, and 0. sineiisis, Elwes. 



Apatura ilia ab. inikuni ab. nov. 

 Male. On the upper side this insect very closely resembles the 

 same sex of A. iris, but the general colour is browner, the three sub- 

 costal white spots of the fore wings are larger, and almost confluent ; 

 there are four black spots in the cell, and the black spot on the outer 

 marginal area is ringed with fulvous. The white band on the hind 

 wings is narrower and very irregular ; the black spot in the first 

 median interspace is fulvous ringed, and there is a fulvous dot above 

 it ; the interrupted submarginal band is also fulvous. Under surface 

 of all the wings strongly suffused with tawny, the markings pretty 

 much as above, except that the black spot in first median interspace 

 is reduced to a mere dot, and the dot above it is white ; the outer 

 marginal area has a double series of more or less confluent, lilacine 

 lunules, except towards the apex of the fore wings. Expanse, 

 80 millim. 



Hab. Japan. One male specimen from Mikuni, Province of 

 Bimgo, June, 1896. 



Possibly a dimorphic form of A. ilia var substituta, Butler.
