BOARMIA. By L. B. PROtrr. 387 



at the angle; discal dot large, followed immediately by a blackish, anteriorly dentate median shade; postmedian 

 profoundly dentate, running from near apex and meeting median shade on hindmargin, met near the apex 

 by an oblique black streak from distal margin. Hindwing with large discal dot, followed by ciu'ved median 

 line and dentate postmedian. Expanse about 30 mm. W. Algeria. 



B. bituminaria Led. (25 h) has about the shape of cinctaria but is somewhat larger. Smoky grey, not bUitminaria. 

 glossy. Antemedian line of forewing angled near costa, then somewhat oblique, postmedian somewhat as in 

 cinctaria, lunulate-dentate, median shade central, distinct but not sharp; a rosin-broMii band between the 

 postmedian line and the subterminal; fringe yellowish grey, dark chequered. Hindwing similar. Underside 

 dull smoke-grey, very weakly marked. Altai, Uliassutai, Amur and Ussuri districts. 



B. crassestrigata Chr. (20 f ) would perhaps be better referred to Hemerophila, as the fovea is wanting, crasseslriga- 

 The name-typical form is easily recognized by its ochraceous or reddish colouring, as well as by the ocellated ^• 



discal spots. — ^ discreparata G'raes., said to be the common form in the Ussuri district, is light ash-grey with discrepara- 

 darker (brownisch) bands. — crassestrigata inhabits Ussuri, Korea und Japan. ■ 



B. biittneri Hedem. (= ochraceata Stgr., appositaria Herz nee Leech) (20 f) is still brighter ochreous, hnuneri. 

 more uniform, the lines deep ochreous, median and antemedian less convergent on hindmargin. This species 

 also lacks the fovea and makes such a distinct impression that Statjdingee has referred it to Angerona (earlier 

 to Gonodontis !); it forms the genus Heterarmia Warr. The antennal pectinations terminate in tufts of cilia. 

 Amur, Korea. 



B, koreana Alph. has perhaps about the colouring of appositaria, though the incorrect figure looks koreana. 

 nearer biittneri. Pectinations long. Fovea developed. Lines nearly as in biittneri, though the less curved post- 

 median suggests a relationship with castigataria. Distal area more uniformly darkened than in appositaria, 

 a complete, dentate pale subterminal. Said to be not uncommon in Korea. 



B, appositaria Leech (20 f ) somewhat resembles biittneri, but is by ilo means so near to it as Leech appositaria. 

 supposed. xA.ntennal pectinations long, not ending in tufts of cilia, fovea developed, neuratioii intermediate 

 towards that of the subgenus Boarmia, whereas in biittneri the 1st and 2nd subcostals are free. Smaller, more 

 brown (not or scarcely ochraceous), distal area irregularly darkened, rendering conspicuous in places the light 

 subterminal line. Kirin (Manchuria), Korea, Chang Yang and Mou-pin. 



B. incongruaria Leech (20 f ) is coloured like the darkest appositaria and with the same distal sha- incongrua- 

 dings, but has short, stiff pectinations, slighter fovea, 1st — 2nd subcostal only quite shortly stalked, wings *"*"• 



rather narrower, underside and hindwing quite weakly marked. AV. China: Omei-shan. 



B. motltanaria Leech (20 f ) comes very close to incongruaria in shape and structure, but the dark montanarin. 

 cloudings are much stronger even than in appositaria and it is easily distinguished by the large discal spot of 

 the forewuag and the strongly dotted (on the veins) postmedian line of the hindwing. AA'. China: Omei-shan, 

 Ni-tou and Che-tou. 



B. rybakowi Alph. is unknown to me, but should be recognizable at once by the ^ antenna (unless rybakowi'. 

 Alphbbaky has mistaken the sex of his specimen), for the pectinations are said to be very short and are figm-ed 

 as mere lamelles, without ciliation. Otherwise similar to montanaria but lighter, greyer brown, the dark 

 cloud less dark, not extending beyond the subterminal line, proximal area and hindwing not clouded. AA'. 

 China: Oupin (Kan-su). 



B. conjungens Alph. (20 g). Size, shape and general aspect of Hemerophila dejeani Ob. (20 b), but with a confungens. 

 fovea. Very like the light, grey-brown, not very strongly banded examples of dejeani but with the lines of 

 the forewing placed nearer together, postmedian less oblique, its subcostal projection less long. Amdo district. 



B. cinctaria Schiff. (= pascuaria Brahm, projecta Walk.) (20 f). Very variable, but recognizable in cinctaria. 

 most of the forms by the elongate white, often black-ringed cell-marks and the rather strongly curved black 

 antemedian line, preceded (basewards) by a strong, similarly cm-ved fuscous band or thicker line. • — ab. cami- ca«ii?iarmto. 

 nariata Fuchs is unicolorous smoke-colour. — nigraria Rbl. (= erebaria Krulik.) is virtually a synonym, repre- nigraria. 

 senting the most blackened examples. — ab. submarmoraria Fuchs (= pascuaria Huene nee Brahm) has the sulmamior- 

 median area whitish, the basal and distal areas of the forewing and, to some extent, the distal of the hindwing '"""'"• 



strongly darkened. — ■ ab. maculata Reuter is smaller and darker than the name-type, more unicolorous, with maculaia. 

 the discal spot much larger. — ab. consimilaria Dup. (= consimiliaria Rbl.) lacks the discal marks. The ground- consimila- 

 colour is commonly in this form whitish (lucialata Fuchs), the lines strong, rather widely separated. — ab. ""• 



ieletntilt Rbl. is a strange form, parallel to Er. leucophaearia ab. nigrolinearia, the distal area mostly whitish, deletaiia. 

 the ordinary markings more or less obliterated, median area of forewing somewhat clouded, with black lines 

 on the veins. — insolita Btb\, from Japan and the t^ssuri (and ? Altai), would scarcely need separafng from imoli/ii.
