306 DILOPHODES; POGONOPYGIA; PERCNIA. By L. B. Protjt. 



incompo- M. iiicompositaria Leech (14 d). A large species, the spots washed-out brown-grey, not blackish. 



*' '"'"■ base of forewing almost without yellowish or reddish. Chang Yang, Central China. 



nigromargi- M. (?) nigromarginaria Leech (lid). Very distinct in the broad smoky black border of both wings: 



nana, rjj^g whig-shape and rather more delicate buUd also suggest a doubt of the generic position. W. China; 

 Wa-shan. The type remains unique. 



4. Genus: Dilopliodes Wan. 



Antenna in (J with fascicles of cilia. Coxae and abdomen beneath furnished in (J with strong tufts 

 of hau'. Forewing with 1st and 2nd subcostals stalked, their stalk anastomosing with costal or forming a 

 small loop so that only the 1st anastomoses. Fovea present m (J. 



Only one species known, ranging from Japan to N. India. Related to Percnia and Abraxas, but 

 distinguished by the neuration as well as the ^ hair-tufts. 



elegans. D. elegans Btlr. (17 a). Easily distinguished by the structure. Rather near Pogonopygia consficuaria 



except ia shape, but the submarginal and marginal spots are less elongate and form much more interrupted 

 rows. In the name-typical race from Japan both wings are heavily black-spotted, though somewhat variable. 

 A local race occurs in Central and W. China, approaching on the hindwing the Indian subspecies khasiana Warr. 



5. Genus: Pog'oiiopyg^ia Warr. 



Differs from Dilophodes in the narrower wmgs, especially of the (J, and in the neuration, the 1st and 

 2nd subcostals being free. v 



There seems to be only one species, nigralbata Warr., described from Assam, from which the Palearctic 

 form here given is perhaps scarcely differentiable. 



conspicua- P. conspicuaria Leech (14 f) may be known by its shape, the smoothly and thinlj^ scaled white grornid- 



'"'^" colour and the broad black borders, intersected by white veins and subterminal line, the latter often more 

 or less interrupted or obsolescent. Gifu and Central China, widely distributed. 



6. Genus: Percnia Ouen. 



Palpus rather short. Pectus densely hahy. Abdomen not tufted beneath. Forewmg long and narrow ; 

 all the subcostals present, sometimes free, sometimes with anastomoses or connections. Fovea present. 



Geographical distribution: N. India to Japan. 



The genus, as at present constituted, embraces some little variations of structure, but is generally 

 recognizable by the elongate white wuigs marked with rows of black spots, in the typical group all of small 

 size. Most of the species are large or moderately so. 



A. Antenna of <^ with s h o r^t pectinations {Xenoplia Warr.). 



foraria. P. foraria G-wen. (14 e). Smaller than the similarly marked species, in general clearer white, the fore- 



wing scarcely so narrow. Japan; China; N. India. 



B. Antenna of cj c iliat e d (Percnia). 



aOnnigra'a. p, albinigrata Warr. (14 e). Almost pure white, more thickly scaled than most of the species, the 



spots very black, large, especially the postmedian series. Japan and nearly throughout China. 



luridaria. P. luridaria Leech (14 e). Recognizable by the large blotches at apices, costal margin and especially 



at middle of inner margin of forewing. Superficially similar to Metabraxas rufonotaria but without the rufous 

 marks and with different antenna. W. China: Mou-pin and N. W. of Cheng-fu. 



grisearia. p. grisearia Leech (14 e). Base and apex of forewing strongly dark-.suf fused, postmedian row of spots 



followed on forewing by a strong, on hindwing by a sUghter, narrower, often incomplete dark band. Central 

 and W. China.
