188 SPARTA. By L. B. Prout. 



it is called Heterophleps H.-Sch., in the Palearctic Region Lygranoa Btlr. and in India Dysethia Warr. It only 

 varies in the d' antennal structure. 



A. Section Lygranoa {= Dysethiodes). cf antenna pectinated. 



fusca. L. fusca Btlr. (6 d). Forewing brown, the lines often scarcely appreciably darker, but arising from 



strong black costal marks; the anteraedian mark is slightly oblique outwards and reaches into the cell; the 

 postmedian is broader from costa to just beyond the 5"' subcostal, then very slender and very oblique outward 

 to the 1" radial. Hindwing scarcely paler, unmarked or with faint sinuous line just behind the middle. Under 

 surface nearly unmarked, hindwing paler than above. Japan, Ussuii, Korea and China. 



B. Section Heterophleps {-^Dysethia). c^ antenna ciliated. 



pallescens. H. pallescens Warr. (11 d, as pulveraria; lie). Larger and paler than fusca, the costal spots more 



brownish black, perhaps in general rather smaller (at least the postmedian) the antemedian line less incurved 

 in cell, the postmedian less sharply angled at the 1^' radial, both marked with dark teeth on the veins. Hind- 

 wing with postmedian line angled outwards behind S""^ radial and inwards on the fold. Underside rather more 

 yellowish. Japan: Oiwake. The shape varies, but our figure He exaggerates the tooth in the margin of the 

 hindwing. 



sinuosaria. H. sinuosaria Leech. (11 c). Size oi pallescens, ground-colour of forewing less uniform than in the two 



preceding, being bright brown, clouded with darker in the basal and distal areas and in the middle of the 

 wing. An antemedian oblique dark line rather near base, sharply angled outwards on the fold; discal mark 

 elongate; postmedian costal spot large, the line from it finely sinuate; postmedian pale line strongly lunulate. 

 Under surface with distinct cell-marks and postmedian line. Ta-chien-lu, July. 



confusa. H. confusa Wileman {= fusca Meyr., nee Btlr) (11 d). Size of fusca, darker brown, the antemedian 



black costal spot vertical or very slightly oblique inwards, the postmedian scarcely so acutely angled anteriorly, 

 less sharply defined between 5"" subcostal and P' radial, distal margin of forewing more bent in the middle, 

 of hindwing more convex (rounded) about the 3'''^ radial. Still more sharply distinguished by the structural 

 characters; in addition to the antennal difl'erence, the inner margin of the cf hindwing is less cut away, the 

 P' median vein well developed, occupying the same position as the 3'''' radial of fusca (i. e. running to the 

 anal angle), the 2""* .subcostal less remote from the P' radial. Japan: Hondo and Yezo, May — July. 



C. cf unknown. 



grisearia. H. grisearia Leech (1 1 d). Size ot pallescens and sinuosaria and probably referable to section B. 



Apparently nearly related to sinuosaria but of a quite difl'erent colour, pale violet-grey, dusted and clouded 

 with brown. Forewing with first costal spot larger and more regularly triangidar than in the other species, 

 second blotch nearly as in sinuosaria; discal dot vei-y small; antemedian line nearly vertical on hindmargin, 

 here strongly marked, but becoming obsolete; postmedian chiefly marked by dots on the veins; subterminal 

 much interrupted. Pu-tsu-fong and Kia-ting-fu, W. China, June — July. 



32. Genus: l^^pai'ta Styr. 



Face smooth. Palpus exceedingly minute. Tongue rudimentary. Antenna in cf bipectinate with long 

 branches, in ? simple. Hindtibia with all spurs. Frenulum wanting. Forewing with costal margin nearly 

 straight, distal margin nearly as long as costal, curved posteriorly, hindmargin extraordinarily short; areole 

 double. Hindwing extremely small and narrow, costal vein remote from cell, connected by an oblique bar 

 rather near the base, cell rather short and narrow; cf with 2"*^ subcostal and P' radial from apex of cell or 

 very shortly stalked, 2""* median and submedians wanting, inner margin with a small lobe at base, formed 

 into a sort of pocket; ? with all veins, submedian short, 2"'' subcostal rather long-stalked. 



A very curious genus, containing only a single species, which seems to show a relationship to the 

 South American Dyspteris. According to Dampf, Lederer's name for this genus and species {Celonoptera miri- 

 ficaria) seems to have been published Ijefore St au dinger's; the part of the Bei-l. Enl. Zeitschr. containing the 

 former is dated iVIay, 1862, that of the Slett. Ent. Zeit. Apr. — June, but Staudinger writing to Milliiire in 1863 

 says the latter really appeared first. Exact contemporary evidence is needed.
