352 ERANNIS. By L. B. Proitt. 



f orewing runs slightly curved from the costa at two-fifths to the base of the hindmargtn, the postmedian nearly 

 parallel to it, from the costa at three-fourths; median shade present, less oblique, arising near the antemedian, 

 ending near the postmedian. $ unknown. East Turkestan: Aksu. 



leucophaea- E. leucophaearia Schiff. (= dira Btlr., triUnearia Sibille) (18 k). Nearest to bajaria, forewing of ^ 



J '■*«■ with distal margin straighter, hindwing with costal margin relatively less long; ground-colour generally whiter. 



Antennal pectinations shorter, ending in longer cilia. Extremely variable. The type figure (Htjenee's) is 



tolerably uniform brown-grej', the basal and postmedian areas only a little browner, all the 3 lines strong. 



nigricaria. $ apterous. — ab. nigricaria Hbn. (18 k, as marmorlnaria) has the proximal and entire distal area (except 



a subterminal line) strongly darkened, the median area light, marmorinaria Esp. (a yormger name) represents 



medioobscu- an intermediate form, but need not be separated. — ab. tnedioobscuraria Vfjeln has the median area largely 



raria. fQJed- in with blackish, especially between median and postmedian lines, basal and distal areas paler. — ab. 



ebenica. ebenica Delahaye is a remarkable aberration with black band along the costa,\ widening mto an oval, and some 



merularia. longitudinal reddish marks. — ab. meritlaria Weymer (= funebraria Th.-Mieg, fuscata Haverkampf) is uniform 



nigrilinea- fuscous brown or blackish. — ab. nigrilinearia Leech has the median area much narrowed, with the median 



''*"■ vein here broadly black, the whitish subtermmal broadened into an ill-defined band which occupies most 



of the distal area. — Egg long-oval, pointed at one end; light grass-green. Larva rather stout, usually gieen, 



with brown dorsal blotches. On oak. Moth from February (or even January) to March or April, Central and 



parts of S. Europe, Sjria, Ussuri district and Japan. 



aurantiaria. E. auratitiaria Hbn. (= mellearia Scharfenb.) (18 k). The (J differs from all the other species in its 



bright golden-brown colour, otherwise close y related to marginaria. Antenna (as also in marginaria) pectinated 



fumipenna- similarly to that of leucophaearia. $ golden-brown, wmgs extremely short, with 2 dark lines. ■ — ab. fumi- 



ria. pennaria Heilweger. Forewing infuscated (violet -brown), onlj'' the fringe yellow; hindwing also more or less 



fasciata. siuoky. — ■ (J-ab. fasciata Linstoiv has a dark band distally to the postmedian line. — Egg flattened at one end, 



longitudinally ribbed, purplish. Larva slender, brown or blackish dorsally, with ochreous yellow spots on the 



sides. On oak, birch, hornbeam, etc. The moth emerges in October and the beginning of November and is 



locally common in Central Europe, etc. Also in the Taurus. 



marginaria. E. marginaria F- {= testacea Retz., progemmaria Hbn., capreolaria Esp.) (18 k). ^■. less golden than 



the preceding, with somewhat lighter median area and interrupted subterminal line and whitish hindwing. 



diversaria. Terminal dots conspicuous. $ with both wings longer than m aurantaria, elongate posteriorly. — ab. diver- 



saria E. {= rufipennaria Fuchs) has the forewing uniformly reddish. Lines as a rule normal, in Fabeicius' type 



denigraria. obsolete. — ab. detiigraria Uffeln has the forewing (cJ) infuscated from the base to the median Hne and from 



fuscata. the postmedian nearly to the distal margin. $ infuscated in proximal half of wings. — ab. fuscata [Mosley] 



(= infutnata Fuchs, uniformata Fuchs) has both wings strongly infuscated, almost black. Chiefly English. 



pallidata. — ab. pallidata Trti. is whitish, ,, resembling the coloiu: of ankeraria as figured by Millieeb". Lombardy 



and Sicily. — ■ Egg ovate, greenish, becoming reddish on the upper side. Larva very variable, shaped like 



the preceding but generally lighter in colour, more yellowish or greenish ; a dark subdorsal shade. Melanotic 



larvae also occur in the same localities as ab. fuscata. Polyphagous on deciduous trees. Moth in March — April, 



in mild seasons beginning to appear earlier. \\'idely distributed in Europe, the Ural, Caucasus, Taurus, etc. 



ankeraria. E. ankeraria Sf.gr. (181). cj*: size of Diarginaria, wings broad, delicate, thmly scaled, light brown, 



discal spot large and oval, lines fine, the postmedian strongly curved at the radials; hindwing white. Antenna 

 dentate, with fascicles of cilia. $: similar to that of defoliaria, smaller, the dorsal spots more confluent. 

 Hungary. 



bela. E. bela Btlr. (= bistriata Hedem.) (18 1). Colour of marginaria, forewing broader, with more pointed 



apex, postmedian line of forewing almost straight, antemedian usually weak or obsolete. ^ antenna about 

 as in the following. $, according to Peyee, ,, semi-apterous, lUte marginaria"' . Japan and the LTssuri district. 



defoliaria. E. defoliaria CI. (= pulveraria Hufn. nee L., discolor Strom, bistrigaria Giorna) (18 1). (^: longer- 



winged than aurantiaria and marginaria, on an average larger, the cell-spot and often the lines blacker, ante- 

 median strongly bent on the fold. Extremely variable, but always recognizable by the shape and by the 

 antenna, each joint of which bears two pairs of fascicles of very long cilia. 2: apterous, whitish or pale yello- 

 wish, dotted with black and with pairs of black dorsal spots. The name-type {^) has a pale yellowish ground- 

 holmgreni. colour, with indistinct reddish bands accompanying the lines. — In ab. holmgreni Lampa (= ? compressaria 

 obscurata. Rothke) (18 k) the bands are wanting. — In ab. obscurata Stgr. in addition the ground-colour is darkened (dark 

 progressiva, reddish brown, in extreme cases almost black). — ab. progressiva Haverkampf (= brunnescens Rbl.) is brown 

 obscura. like obscurata but with the bands black. — ab. obscura Heifer ( = nigrofasciata Neuberger) (18 k) has the ground- 

 colour as in the type or sometimes whitish, the bands blackish. — Egg oval with very shallow, somewhat zig- 

 zag longitudinal ridges, a cell-pattern only discernible on high magnification ; brownish yellow, without gloss. 

 Larva less slender than auratiaria and marginaria, much more gaily coloured; dorsal area variable, red or
