﻿NEW SPECIES OP LEPIDOPTERA FROM CHINA. 45 



double spot intersected by the discoidal nervule ; above is a small dot on the 

 costa, and below are three roundish spots, those in the submedian and first 

 median interspaces are out of line and nearer a submarginal series of spots, 

 the last of which is linear and slightly curved, the next round, and the one 

 above dot-like ; the remainder of the series comprises two pairs of white spots, 

 but the initial one of the costal pair is very small ; there are two other white 

 spots nearer the apex. On the secondaries the markings comprise an oblique 

 streak from the costa to the submedian nervure, one beyond extending nearly 

 to the anal angle, but interrupted by first pair of median branches ; a short 

 bar from the costa broken up by the venation into three spots ; a submarginal 

 band also interrupted ; all, together with a line parallel with outer margin, 

 are obscure fulvous ; the anal lobe and tail are black, the former bordered 

 with whitish. Fringes grey tipped with black. Under surface inclined to 

 brown ; all the markings of primaries are similar to above, but rather paler, 

 less interrupted, and with the addition of a basal band and a marginal series of 

 linear spots. Secondaries with a pale fulvous streak along abdominal 

 margin, which unites before the anal angle with one running from the 

 base parallel with submedian nervure, and enclosing a third broader streak ; 

 an oblique white streak from the costa terminates on the submedian nervure 

 in a point, and beyond is a party-coloured streak, white at the costa, pale 

 fulvous to the second median, and then white again to its termination ; the 

 whitish submarginal band is preceded by a black interrupted streak and 

 followed by a black transverse dash from the costa ; a broad pale fulvous 

 line, white near costa, parallel with outer margin ; anal lobe and tail velvety 

 black edged and fringed with white, above is a whitish cloud. 



$ . Similar to the male, but the markings are paler, much larger, and 

 less interrupted. Expanse, $ 39 mm., $ 42 — 46 mm. 



Two females, Chang Yang, June ; four "males, two females, 

 Ichang, July. 



Allied to D. eg eon, Dbld., from N. India, but easily dis- 

 tinguished by the different characters of the markings. It is 

 also very close to D. eugenes, Bates, and may possibly be only a 

 local form of that species. 



Leucophasia gigantea, sp. n. 



$ . White. Primaries with a large black spot on the second discoidal 

 nervule, sometimes extending upwards to the first ; a smaller one on the 

 discocellular. Under surface of primaries with the black spots faintly repro- 

 duced. Secondaries have an angulated suffused band indicated by a blackish 

 costal streak, and a curved mark between the discoidal and third median 

 nervules; discoidal cell intersected by a longitudinal black bar; the venation 

 is dark, especially on the secondaries and outer margin of primaries. Head 

 black ; collar yellow ; thorax black dusted with white ; pectus sprinkled with 

 yellow ; abdomen white. 



5 . Under surface of secondaries and apex of primaries tinged with yel- 

 lowish, the black markings more band-like, with the addition of a ziczac 

 black submarginal line ; all these markings are faintly seen through from 

 above. Expanse, $ 48 — 62 mm., ? 72 mm. 



The specimens of the May brood are without black spot on 

 primaries, the colour is more creamy, and the venation appears 

 more prominent. I propose the name of immacula for this 

 seasonal form. 



The type is separated from the other species of Leucophasia 

 by the large black spot on primaries, and both forms are dis- 

 tinguished by the yellow collar. 



A fine series taken at Chang Yang in May and August.
