I'uhl.n.n.Whl. TlilCHOBAPTRIA; TRTCHODEZIA. By L. B. Prout. 169 



P. coloraria If.-Sch. (= inelaiiicterata Led) (11 b). Brighl golden-yellow, wilh irregular, broad, aiio-ulaled coloraHa. 

 black markings, which vary somewhat in extent, but of which the general form may be seen from our ligure. 

 Median band on bolh wings not interrupted; apical band extending as far as the first median vein, though 

 becoming very narrow; blotches at hinder angle rather large. Apparently a rare species, only known from 

 the Altai and Eastern Siberia, flying by day at high altitudes. 



P. miegata Poii,j. (lib) differs from coloraria in having the median band more distally placed, inter- miegata. 

 rupted in the middle, the marginal band broken into three parts instead of two, the apical part not reaching 

 beyond the 3''^ radial, a second patch commencing between this vein and the 1 ^' median and extending to 

 the 2°'' median, and a (usually rather small) third patch occupping the hinder angle of the wing. W. China 

 (Mou-pin and Pu-tsu-fong) at elevations of over 3000 m, June and .July. 



P. angularia Leech (lib) resembles miegata (of which Poujade considered it a variety) in the inter- angularia. 

 rupted median band, but differs essentially in the distal markings, which consist of a broader and more 

 extended apical band and a much larger tornal blotch, sometimes (as in Leech's type cf, which we figure) 

 narrowly connected along the distal margin. The markings in the basal part of the forewing and the inner- 

 marginal part of the hindwing are also very different and the fringes are more chequered. Finally, the cT 

 has a narrower hindwing, its distal margin being slightly concave from the anal angle to the middle. W. China, 

 together with miegata and at Ta-chien-lu and Omei-shan. 



14. Genus: Tricli©l)ai)ti*ia 



gen. nov. 



Agrees with Pohjthrena in almost all characters, but the areole of the forewing is double. Super- 

 ficially it also differs in the scheme of coloration, which agrees with that of the succeeding genera. The ? 

 differs little from that of Baptria except in the narrower wings and the shorter anastomosis of the costal vein 

 of the hindwing; the cf is further distinguished by the presence of the long black hair-pencil on the forewing 

 beneath. The type of the genus and the only known species is exseciita, from Japan. 



T, exsecuta Feld. (6 c as kindermanni). Forewing black, with a very fine white antemedian line from exsecuta. 

 the costa to the middle of the wing and a narrow oblique white band from just beyond the middle of the 

 costa to the 1 ^' median vein or somewhat beyond ; often also there is a fine line, usually more or less 

 interrupted, running fi'om the posterior part of this band to the hindmargin, parallel with the distal margin. 

 Hindwing with a single white line or narrow band, continuing the last-mentioned line of the forewing; costal 

 area in the cf white or whitish. Both wings with the fringe white at the apex and between the P' media,n 

 vein and the submedian fold (variably in exact extent), otherwise black. Very variable in the width of the 

 white bands ; the fine antemedian line of the forewing and even the median line of the hindwing are sometimes 

 entirely obsolete, or represented only by one or two white spots. — ab latifasciaria Leech is on an nvevage latifasciaria. 

 smaller, but is chiefly distinguished by having on both wings a broad white postmedian (median) band, that 

 of the forewing rather longer than in the type-form (sometimes almost reaching the distal margin), that of 

 the hindwing usually with an angular projection in its distal edge. — ab. obscurior Th-Mieg only differs from obscurior. 

 the type in the absence of the white band on the forewing above. Described from Japan. — exsecuta is 

 apparently common in Japan (as at Ohoyama, Nikko, Yezo, etc.) and is active on the wing by day, July- 

 August. Leech also records having taken it at Gensan, but I have seen no Korean examples. 



15. Genus: Tl'icIlOClezia Warr. 



Closely related to the two preceding genera, agreeing with Polythrena in the neuration of the forewing, 

 with Trichobaptria in coloration. From both it differs in the neuration of the hindwing; the discocellulars 

 are simply oblique, not biangulate, and the costal vein anastomoses with the subcostal nearly to the end of 

 the cell, which is very short. The hair-pencil on the hindwing beneath is not so long as in those genera; 

 indeed in the North American albovittata Guen., which Warren selected as the type of the genus, it is 

 comparatively ill-developed. 



The genus contains only a few Asiatic and North American species.
