BOARMIA. By L. B. Peout. 379 



B. conjunctaria Leech (21 i) has the markings shaped more as in rhbmboiduria, to which, indeed, it eonjuncta- 

 bears considerable superficial resemblance on the upper surface, though it is rather more mottled and the wings '*'"' 



narrower. Underside paler, greyer, very feebly marked. "^ Ta-chien-lu. 



B. dilectaria Leech (21 i). Larger and much more brightly coloured, cell-spots sharply black, median dilecUnw. 

 line wanting, the others widely separated, the postmedian with a characteristic shape. Abdomen of (J hairy 

 beneath, approaching the section Paradarisa. Ta-chien-lu. 



B. recurvaria Leech (21 i). Smaller and less variegated than dilectaria, median line developed, curved, recunaria. 

 antmedian more bent and more oblique, liindwing lighter. Pu-tsu-fang. Also at Darjiling. Perhaps a colour 

 form of the far darker conspurcata Walk., which also occurs at Darjiling. 



B. tripartaria Leech (21 i). A species standing quite apart. Coloration of forewing a little like that of tripmlaria. 

 grisea Btlr., quite different in structure and shape, the thicker, differently formed black lines and uniform 

 hindwmg. Face smooth, palpus short. W. China: Pu-tsu-fang. 



B. cilicornaria Pilng. strongly suggests a small, weakly marked arenuria. Forewing white, with a dlicornaria. 

 tinge of yellowish and with brown-black strigulation and. markings; an irregular spot near the base, curved 

 rows of spots representing the antemedian and postmedian lines, discal spot" and a spot on costa representing 

 the median, subterminal line dentate, nearly straight, chiefly indicated by a dark band which accompanies 

 it proximally. Hindwing whitish, weakly marked except at inner margin. Japan: NLkko. 



B. sinearia Guen. (= brunnearia Leech) (21 i). Light brown, coloured and marked like afpositaria sinearia. 

 Leech but with different antenna (rather shortly ciliated), the Imes finer, postmedian of hurdwing less cui^ved. 

 Central China to Shanghai. Rare on Japan. — noctivolans Btlr. (= glareosaria Graes.) (25 d) differs in having noctivolans. 

 the median area whitish, the median line oftener obsolete, the rest of the wing in general with coarser dark dust- 

 ing. Japan and the Ussuri district. I have similar, though less extreme, examples from Shanghai. 



B. punctulata Schiff. (= scopularia Thnbg. nee L.) (21 i). Whitish grey with fine dark irroration, the punctulata- 

 lines (including the subterminal) starting from thickened, generally equidistant costal spots. Median line some- 

 times obsolete in middle of wing, sometimes on the other hand thickened; subterminal line irregular, its proxi- 

 mal dark shading interrupted. — ab. obscuraria Paux is blackish grey with the markings obsolete. — ab. albes- o^^^^^^ria. 

 cens ah. nov. is whitish, almost entirely without dark dusting. — Larva without humps, of moderate thickness, 

 green with yellow lines and incisions, or greenish grey or purplish. On birch or sometimes alder in July, the 

 pupa hibernating and the moth appearing in May and June. Distributed in Europe. — ignobilis Btlr. is not ignobilis. 

 quite so broad-winged, on an average smaller, darker or more darkly marked, postmedian line with an outward 

 curve at the median veins and followed distally, on both wings, by a more or less distinct dark shade. Japan. 

 Probably the E. Siberian forms recorded by Staudingee also belong here. 



I. Build not robust. Antenna of (J with very long, very slender ciliation 



(Myrioblephara Warr.). 



B. duplexa Moore is a North Indian species, with the forewmg olive-green (fading to yellowish), duplexa. 

 generally not very heavily dark-dusted, the hindwing generally whitish, except towards inner margin, with a 

 distinct cell-dot and with the postmedian line parallel with the distal margm. Otherwisse quite similar to 

 nigrilinearia. Recorded by Leech from Pu-tsu-fang and Omei-shan. — nigrilinearia Leech (22 i), notwith- nigriUnea- 

 standing the darker dustmg and the different position of the postmedian line of the hindwing, seems to me to be >■»«• 



merely a form of duplexa. The anterior bend in the postmedian line of the forewing is perhaps less acute. W. 

 China: Kia-ting-fu. 



B. decoraria Leech (22 i). Only the $ is known, but it gives quite the impression of a Myrioble- decoraria. 

 phara. Very distinct in the broad, almost clear white median area and the brown admixture in the basal area 

 of forewmg and distal area of both wings. Underside much more weakly marked. W. China: Mou-pin. 



K. Antenna of (J with moderate or long ciliation, abdomen with a pair 

 of strong lateral tufts of hair {Diplurodes Warr.). 



B. parvularia Leech (23 b). Brown with a slight reddish tmgs and with very strong blackish irrora- pan-ularia. 

 tion, often condensed into dark clouding in posterior part of median area and in the neighbourhood of the median 

 vein of the forewing distally. Characteristic is the postmedian line of the hindwing, which is very near the cell- 

 dot and very acutely angulated. Gifu. Probably a form of semiparata Walk. 



L. Antenna of ^ densely ciliated, abdomen clothed with long hair below 



(Gasterocome Warr.). 



B. sinicaria Leech (= orta Bastelb.) (22 k). Build rather robust, wings glossy, easily known by the s'micaria. 

 broadly dark-edged discal mark of the forewing and the broad dark distal margins, that of the forewing sending 

 out a strong proximal projection to meet the cell-mark. W. China: Omeishan. Also on Formosa. Probably a 

 broad- winged, dark-marked form of the Indian pannosaria Moore.
