PHOTOSCOTOSIA. By L. B. Prout. 



47. Genus Photo^coto^ia Warr. 



Face somewhat prominent and roughened. Palpus moderate, rough-scaled. Antenna in cT shortly 

 ciliated. Hindtibia with all spurs. Wings ample, hindwing with distal margin not or scarcely crenulate, costal 

 margin strongly rounded, especially in the cf ; retinaculum very strong. Forewing with areole double; cf with 

 a strong pencil of long spreading hairs arising near the base behind the median vein and covering most of 

 the submedian fold. Hindwing with cell short, its anterior margin very short, the 3'** discocellular being 

 exti'emely oblique; costal anastomosing with anterior margin of cell to a little beyond its middle, then sharply 

 diverging; ,2""^ radial arising somewhat before the middle of the discocellulars. 



Early stages unknown. 



A very natural genus, distinguished from the Calocalpe-PhUereme group by the shape of the hindwing, 

 its discocellulars and the hair-pencil on the cf forewing. The species are among the largest of the Larentiids 

 and many of them are very handsome. Although a fair number of species are known, the geographical range 

 is somewhat restricted. Most inhabit the mountains of Turkestan, N. India and Tibet, but stragglers reach 

 eastward as far as Japan and southward to Java. Trichopleura Stgr. (nom. praeocc.) and Lasiogma Meyr. 

 are synonyms. 



atrostrigata. Ph. atrostrigata Brem. (= lucicolens Btlr.) (5h) is the only species known from Eastern Asia and is 



easy to recognize, although the median area is rather variable, commonly much lighter than in our figure. 

 Hindwing entirely dark or (in the cf) with the costal part white: distal margin darkest, subterminal line present, 

 but often incomplete. Under surface strikingly different, both wings yellow- whitish; forewing with smoky 

 suffusion from base to near the middle (at least in the ?), a black postmedian costal blotch and a dark smoky 

 apical cloud, leaving the extreme apex white; hindwing with a (generally indistinct) curved postmedian line. 

 Japan, S. E. Siberia and Central China. A local race on Formosa. 



mmiosata. Ph." itiiniosata IValk. (6 k). Forewing similar to that of the preceding, but rather more reddish, 



especially in the cf. Hindwing with large oval or sometimes irregularly shaped distal blotch of bright orange, 

 reaching inwards almost to the cell and posteriorly about to the P' median; costal margin in cf broadly 

 white. Underside with the orange colour paler but appearing also on the forewing, the markings of the 

 forewing nearly as in atrostrigata. N. India to W. China and on Formosa. 



propug- Ph. propugnataria Leech (11 g), of which only a single specimen is known, differs from atrostrigata 



nataria. [^ jj^g ghape of the markings of the forewing and in the presence of a small orange blotch in the hindwing 



(much more restricted than that of miniosata). Under surface with the smoky suffusions stronger and more 



extended than in atrostrigata, the line on the hindwing strong, sharply bent between the 3'''^ radial and the 



1 5' median. Wa-shan at nearly 2000 m elevation, taken in June. 



apkinotaria. Ph. apicinotaria Leech (5 k). Forewing in the cf coloured nearly as in miniosata, or sometimes more 



variegated with olive-greenish, thus rather approaching atrostrigata. From both it may be distinguished at 

 a glance by the pale apical patch. Hindwing in the cf similar to that of d* atrostrigata, slightly darker, the 

 white costal area somewhat more restricted. ? rather larger, forewing nearly as in the most variegated cf cf, 

 rather richly coloured; hindwing with an orange patch near apex, reaching from costal margin to 3"* radial 

 and basewards to just inside the postmedian line, cf beneath with darker hindwing than propugnataria, the 

 line less strongly bent; ? more as in miniosata, the orange rather more restricted. W. China, June — August. 



fasciaria. Ph. fasciaria Leech (llf) is very distinct from all the other species in the broad median area, which 



is entirely fdled-in with uniform velvety blackish brown. On the hindwing the orange colour is more extended 

 than in miniosata and shows, in well-marked specimens, a deeply dentate fuscous postmedian line. Forewing 

 beneath yellowish, hindwing more orange, both strongly dusted, except in the region of the postmedian line, 

 with fuscous; postmedian line of forewing shaped as above, of hindwing angled between 3"^ radial and P' median. 

 How-kow, Tibet, July — August. 



funebris. Ph. funebris Warr. (llf) is equally unmistakable on account of its nearly uniform blackish forewing; 



the transverse lines and discal mark are deep black, all the lines more or less dentate. The hindwing also 

 is darker than that of miniosata, which it most nearly resembles in the shape and extent of the orange blotch. 

 Under surface smoke-colour, the orange blotch of the hindwing reproduced; cf in addition with a yellowish 

 blotch distally to the cell of the forewing and nearly reaching the hindmargin. W. China, June — August. 



palae- Ph. palaearctica Stgr. (5 h) is, at least in its typical form, the palest and most weakly-marked species 



arctica. of the genus. The lines are mostly incomplete, but the antemedian is stronger and usually complete and
