370 BOARMIA. By L. B. Proitt. 



songaria. B. soHgarica Alph. (= subfuscaria Stgr.) (20 h). Build slender, face smooth, antennal pectinations not 



very long; 1st and 2nd subcostal of forevving free. Characterized by the mottled, brownish or sandy co- 

 louring and the obsolescence of the lines, which are scarcely indicated except as costal spots and vem-dots; 

 subterminal line dentate, thick, rarely very distinct, strongly bent proximally in the middle, in part dark- 

 shaded proximally. Underside still more weakly marked. Hi district and Issyk-kul, probably also Zerafshan 

 variolaria. and other localities in Central x4sia. — variolaria Stgr. is probably a form of songarica, differing chiefly in 

 its very distinct coloration. The ground-colour is whitish grey very strongly dusted with dark smoke-brown, 

 so as to appear predominantly dark-coloured. The lines are sometimes distinct, sometimes obsolescent, the 

 characteristic subterminal line very conspicuous, white. Ferghana. 



mnbraria. B. utnbrarla Hbn. (20 h) resembles rhomboidaria but is much more strongly black-marked above and 



beneath and sometimes attains a great size. The median Ime of the forewing, which m rhomboidaria is bent 

 round distaUy to the cell-spot, in umbrnria is placed proximally to or sometimes crosses it. Underside characte- 

 decosteraria. ristio, all the lines and some dark spots well expressed on a Ught groinid. — ab. decosteraria Ob. is much 

 powelli. suffused with blackish, especially on the forewing. — powelli Ob., from Algeria, is a smaller form, with the 

 ground-colour rather uniformly grej'ish or brownish, the white patches of the type almost entirely suppressed. 

 Marldngs normal. — Larva closely similar to that of ihomboidaria, generally of a slightly vinous grey-brown; 

 in addition to the lateral protuberance on the 2nd abdominal it bears a slight, elongate, oblique one on the 

 1st. On olive, hibernating. Moth in two broods, distrib'ated from the Mediterranean lands to Transcaspia. 



mandchuri- B. mandschuriaria Brem. (= deiiabowskiaria Ob.) (20 h) is very variable, but mimistakable on account 



ana. ^^ -^^ white ground-colour and blackish markings. According to Meyrick it agrees in structure M'itb fibeata. 

 Amur and Ussmi district. 



venustaria. B. venustaria Leech (20 i) is evidently related to the acaciaria group of the Indo-Austrahan and Afri- 



can Regions (Chogada Moore), the build, shape and pattern recalling selenaria, the (J antennal structure 

 rather characteristic, the pectinations, though long, ceasing rather abruptly at about one-half or two-thirds, 

 a long apical part remaining simple, venustaria does not vary and is recognizable at a glance. Japan: 

 Oiwake. 



repulsaria. B. repulsaria Walk. { 20 i) belongs to a small subsection of the acaciaria group in which the $ an- 



tenna is bipectinate (C'arecomotis Warr.). On account of the narrower wings and different neuration (1st 

 and 2nd subcostals both well free) it cannot be united with the section Ophthalmodes, m which this is also the 

 case. Size of venustaria, rather narrower, dark, dingy bi'0\TO-gre5', the median area only a little lighter, nar- 

 rower, cell-marks more broadly dark-edged, postmedian Ime continuous but not sharp, curved outwards at 

 radials. ^ antennal pectinations longer and coarser. Described from Hong-kong, but Dr. Seitz has taken it at 

 Shanghai and Wileman an example on Japan. Also inhabits Formosa. 



leucophaea. B, leucophaea Btlr. (= elegans Ob.) (20 i) has the cell-marks similar to those of cinctarin but is larger. 



with longer antennal pectinations, median area not paler than the rest of the wing, postmedian line more 



strongly dentate, the white spot on the forc-ning between this and the subterminal (indicated in some cinc- 



pagina. taria) very strongly and charcteristically developed. — ab. pagina Wilem. is a lighter, greyer $ form, 



the $? of leucophaea are generally less brown than the ^^. — Jap-an and the Ussuri district. 



nigrofasci- B. tiigrofasciaria Leech is regarded b;^ PiJNGELER as distinct from the preceding. It is characteri- 



aria. ^e^ jjy i\yQ strong black median Ime (on the forewing bent round the cell-spot), obsolescence of the charac- 

 teristic white outer spot and stronger development of a longitudinal line behind this (between the 2nd and 

 3rd radials). Ground-colour rather more violaceous grey, sometimes much less dark-dusted. As more or less 

 intermediate forms occur, I doubt its validity. Japan. 



repandata. B. repandata L. ( = bistortae Vnllot) (20 i) and a group of nearly allied forms or species are gene- 



rally characterized by the course of the postmedian Ime of the forewdng, which bends suddenly basewards 

 at the fold, thus forming a second conspicuous projection, in addition to the usual anterior one. repandata 

 is excessively variable and some of the forms are difficult to classify. The name-type has a cinereous ground- 

 destrigaria. colom' and rather strong brown and fuscous markings. — ab. destrigaria Haic. has the ground-colour paler 

 ■muraria. but more strongly dusted, the fuscous lines subobsolete, subterminal line distinct. — ab. muraria Cttrt. is 

 rather uniform grey, almost without browi: admixture, in general weakly marked. Forms a local race in 

 nigricata. maiaj' parts of N. England and Scotland, also according to Staxjdinger in the Amdo district. — ab. nigri- 

 cata Fuchs (= fumosae Gregson, nigra Tutt) is almost or altogether black, sometimes with the subterminal line 

 nigropallida. vemnining whitish. England and Germany. — ab. nigropallida Mansbridge is a modification of nigricata 

 ochronigra. with silvery grey patches in the middle of tiie wing. — ab. ochronigra Mansbridge is another modification of 

 conversaria. nigricata, with the subterminal shades yellow ochreous instead of whitish. — ab. conversaria Hbn. is a beau- 

 tiful form (or group of forms) with the median area black; the succeeding area is sometimes clear white. - —
