BOARMIA. By L. B. Pboot. 371 



sodorensium Weir is a small leaden grey form from the Hebrides, adapted to the gneiss rocks on which it aodorensi- 

 rests. — depravaria Star, is another small <irey race, probably less dark a)id more miicolorous than the , ^'*'" 



preceding, but I cannot compare them. Distributed in Central Asia (Ferghana to Hi, Ala Tau, etc.). ■ — 

 deversata Stgr. is similar to conversaria, ground-colour greyish, median band narrower posteriorly, followed deversata. 

 distally by a roundish black spot behind the 3rcl radial. Kentei and Alai Mountains. — Larva twig-like 

 but without humps, sides puckered, face flattened. Very variable, the ground-colour some shade of brown, 

 commonly with dark spots or marblings. Polyphagous, hibernating. Pupa glossy, red-brown, in a very slight 

 cocoon in the earth. On the wing in June and July; Europe to Transcaucasia. 



B. admissaria Guen. (20 i) represents repandata in Afghanistan, N. India, Tibet and China and is fully admissaria. 

 as variable. It needs exhaustive study, as the antennal pectinations vary in length. Individual examples 

 are sometimes scarcely separable from repandata, but as a rule the species (or race) shows the following charac- 

 teristics. Wings relatively more elongate, the forewing above and especially beneath Avith more dark clouding 

 in the distal area, the space between the median and postmedian lines, on the other hand, very commonly pale 

 or even white, the median hne generally well developed, postmedian line of hindwing generally more bent or 

 angled at the 1st radial. The name-type has the median area rather light yellow-grey, the dark markings mode- 

 rately well expressed. — nudipennis Warr. is more violet-grey, the lines well marked, the clouding in the nudipennis. 

 distal area almost obsolete. Antennal pectinations long. N. W. Himalayas. — ab. (?) iterata Btlr. (20 i). Ground- Uerata. 

 colour about as in the type, median line very strong and thick. Distributed. — ab. ( ? ) trikotaria i^eM. The Mkoiaria. 

 space between antemedian and median lines filled up into a narrow dark band, the distal half of the median 

 area broadly whitish. Distributed. — ab. ( ?) subnitida Warr. Rather dark grey, paler in the disc, the lines suhnitida. 

 weak. — nobilis Alph. Variegated, the median area almost entirely pale, the distal (also on the hindwing) nohilis. 

 strongljr clouded with brown. W. China. — obsoletaria Leech (20 i). Almost unicolorous light brownish, with dbsoletaria. 

 ceU-dots and remnants of the dark markings. Tibet: Hou-kow. — perspicuata Moore {= vicina Moore), perspicuaia. 

 Much brighter ochreous brown, the median and postmedian Imes acutely angulated on the fold ; dark borders 

 on .^nder surface strong. Antennal pectinations long but rather less in number than in some of the forms. 

 Dharmsala to Central China. 



B. maculata Stgr. (21 a) has been proved by the genitalia to be a distmct species from repandata. mucuiata. 

 Purer ash-grey than European repandata, with less Proration, almost always with three distinct black lines, 

 distaUy to the third a black spot as in repandata deversata (which should possibly be removed here?). ^ an- 

 tenna with longer pectinations. Distributed in Siberia, entirely supplanting repandata in Amurland. — ha^ttX-iustelhergeri. 

 bergeri Hirschke is the European representative of maculata, variable but in general larger and more strongly 

 marked. Prom repandata, apart from the structure, it may generally be differentiated by the less bent ante- 

 median line, strong median shade, usually approximated thereto, and more strongly marked underside. 9 upper- 

 side less characteristic, median shade less thick, less straight, more distally placed. Larva closely similar to 

 that of repandata. Distributed from Switzerland to Bukowina, overlooked until recently. It flies at the end 

 of July and in August, thus later than repandata. — Whether maculata is structurally distinct from admissaria 

 remains to be investigated; I am inclined to doubt it. 



B. picata Btlr. (21 a) resembles admissaria ab. trilcotaria but with stiU darker distal area; equally picata. 

 noticeable on the hindwing (where the sabterminal line shows up prominently) and on the underside. The 

 forewing beneath has a very conspicuous light median band, not (as in trilcotaria) encroached upon in the 

 middle by a strong dark projection from the distal area. Apparently not variable, except that the $ is ligh- 

 ter. Japan. 



B. columbinaria Leech (21 a) is similar to some of the most mottled grey forms of admissaria, but easily columhina- 

 distinguished by the admixture of light blue-grey scales in the fuscous parts, giving it quite a distinctive '"*'*■ 



tone. Antennal pectinations much shorter. Central China: Chang Yang. 



B. extinctaria Ev. {= exustaria Stgr.) (21 a) again resembles the greyer, most weakly marked forms eximdaria. 

 of repandata, but differs in the course of the postmedian line of the forewing, which is less bent, and in the 

 underside, which lacks the distinct light apical and mid-terminal spots of repandata. The antennal pectina- 

 tions are perhaps shorter. Grey, with all 3 hues generally indicated, but very weak, the antemedian proxi- 

 mally and the postmedian distally accompanied by indistinct yellow-brown bands. Distributed throughout 

 Asiatic Russia. 



B. moupinaria Leech (21 a) is a sober grey species with the postmedian line more straight than moupinaria. 

 in any other of the group, almost entirely parallel with the distal margin. A tmge of yellowish is noticeable in 

 the basal area and on the postmedian line. Forewing beneath somewhat smoky, darker distally, hindwing dirty 

 whitish. W. China: Mou-pin, only the type known. 



B. moesta Btlr. (= cinerea Btlr.) (21 b) is darker and more brownish grey than moupinaria, somewhat moesta. 

 more mottled, without the yellowish line, the postmedian line more bent (though less so than in repandata), 

 the subterminal more deeply dentate. Ground-colour whiter beneath than above, but with strong dark dusting, 

 the basal half of the hindwing the whitest, both wings darkened distally to the postm^edian line. Japan.
