PTYCHOPODA. By L. B. Prout. 103 



it differs essentially in the narrower distal area, especially in the anterior part of the forewing and on the hind- 

 wing, where also it is more sharply defined. (^ antenna with fascicles of long cilia; hindtarsus not abbreviated. 



Pt. roseolimbata Pouj. (5 d). Pale straw-colour with the costal margin of the forewing (as far as the roseoUm- 

 subcostal) and a broad distal border to both wings of a beautiful rose-pink, the former with some dark ^"'''• 

 dusting, the latter traversed by a usually much interrupted subterminal line of the ground-colour and usually also 

 more or lessmarkedwiththeground-colour at the distal margin. Lines wanting, or the postmedian very faintly 

 indicated as a sinuous proximal edging to the pink border. Cell-dots blackish, quite small. Under surface 

 duller, the bordering being grey with only a very slight admixture of pink, and the forewing being more or 

 less suffused with the same grey basally; postmedian line better defined than above. Varies only in the extent 

 of the straw-coloured markings in the pink borders, which may occupy nearly the whole of the space be- 

 tween subterminal line and termen, or may be much more restricted. (J antenna with long fascicles of cilia; 

 hindtibia short, tarsus not abbreviated. Apparently distributed in the mountains of W. China at elevations 

 of 1500 to above 3000 m, occurring in June and July. A very beautiful and very distinct species, being 

 larger than the allies and with broader, brighter margins. 



Pt. nielseni Hedem. (== latimarginata Warr.) (3 f) is smaller than the other rosy-margined species, the nielseni. 

 borders, as in roseolimbata, broad, but their colour less bright, more as in jaJcima Btl. Ground-colour pale yellow- 

 ish straw-colour, the costal margin of the forewing purplish pink. Both wings with dark purplish discal dot 

 and dark bisinuate postmedian line to which follows the purplish pink border, which is partly interrupted 

 with the ground-colour at the distal margin itself. Forewing in addition with a weak or obsolescent ante- 

 median line. Underside similar, the costal margin and sometimes the entire cell of the forewing rather more 

 suffused. cJ antennal ciliation moderately long; hindtarsus not abbreviated. Amurland, Central China and 

 Japan, showing no geographical variation. Warren in renaming this easily-recognized little species must 

 have overlooked von Hedemann's description. From roseolimbata, apart from its much smaller size and less 

 bright colouring, nielseni differs in having the postmedian line better expressed, more deeply sinuate and 

 feebly dentate. 



Pt. manicaria H.-Sch. (= volitaria Joan.) (4e) is at once distinguished from nielseni by its brown, manicaria. 

 not purplish distal border, but also differs in other respects. The wings are not very broad, the apex of the 

 forewing rather sharp, the distal margin slightly flexuous, being more convex in the middle than anteriorly. 

 Ochreous light-brown, coarsely irrorated with reddish brown; lines reddish brown, the antemedian (present on 

 forewing only) curved somewhat in S-shape, the postmedian slightly curved, followed by an ill-defined dark 

 (red-brown) shade, which bounds the subterminal line proximally; cell-spots redbrown, rather variable in size; 

 median line finer and weaker than the others, placed distally to the cell-spot on forewing and proximally on 

 the hindwing. Under surface similarly marked. Local, Spain and N. Africa. I have only seen $$. 



Pt. fractilineata Zell. {— inclinata Led.) (4 c). Forewing whitish, strongly mixed with pale clay-co- fracti- 

 lour which usually (as in the specimen figured) leaves only a narrow and ill-defined antemedian line, a broader ^^^^ "• 

 postmedian, closely followed by a very fine, little noticeable line, and rather irregularly bent subterminal 

 of the pale colour; cell-spot black; fringe with some obscure, sometimes nearly obsolete dark marks. Hind- 

 wing shaped nearly as in dimidiata (the excisions not shown in our figure); usually more whitish and more 

 weakly-marked than the forewing, at least in its proximal part; sometimes more nearly agreeing with it; cell- 

 spot small and indistinct, occasionally wanting; a strongly bent subterminal line nearly always discernible. 

 Under surface more weakly marked. Although I have before me for examination scarcely a dozen specimens 

 of this species these are sufficient to indicate that it is subject to considerable variation in size, colour and 

 markings. Some examples are much smaller than the one figured, the tone is sometimes greyer, while there is 

 not infrequently a more or less distinct dark band (occasionally very strong) proximally to the subterminal 

 line and some weaker dark shading distally to it. In the most strongly-marked specimens there is some coarse 

 fuscous dusting in the basal area and distinct fuscous antemedian and postmedian line are present, the latter 

 being an accentuation of the clay-coloured line which separates the whitish band from the whitish line that 

 follows it. But notwithstanding this variability and the fact that it is a rather inconspicuous species, frac- 

 tilineata is really not difficult to recognize if the shape of the hindwing, the structure, and the course of the sub- 

 terminal line (which is strongly outcurved behind the middle) be taken into consideration. Zeller's type and 

 a few other examples show all the lines present though without the fuscous shading, the postmedian of the 

 hindwing almost right-angled on the 1. radial. (J antennal joints somewhat projecting, with slender fascicles of mo- 

 derately long cilia; hindleg short and weak, tarsus abbreviated. S. Spain, Sicily, Algeria, Egypt to K. Syria. 

 April-June, probably throughout the summer."^ — SUbrtlfaria Stgr. may probably be only a form of fractili- subnifaria.
