ASTHI'JNA. By L. B. Prout. 271 



D. blomeri Curt. (^= pulchrai-ia Jw.) (10 g ?, 10 h cP) difl'ers from the other species which have a hlomeri. 

 cheslnuL-coIoui'ed patch near the apex of the forewing in that the median area is broadly wJiitish or grey- 

 wlilte without distinct mariiings; near the base tliere is an ill-defined reddish-brown band. Hindwing greyer, 

 especially towards the distal margin, on the underside whiter. — Larva of moderate proportions, rugose at 

 the sides, incisions well marked; greenish yellow, thorax with an elongate red dorsal patch, abdomen with 

 some red lateral blotches; occasionally, however all the red markings are suppressed. On Ulmus montana in 

 August — September. Pupa short and thick, tapering rapidly to the anus, which is blunt but has a sharp 

 cremastral spike; chestnut brown with green wings; hibernates. The moth appears generally in June or July. 

 Extremely local in Central-Europe and the Ural; also recorded from Amurland and Japan, whence I have seen 

 no examples. 



D. semistrigata Chr. Size of hlomeri, the brown band less bright, narrower, placed nearer to the discah^wisiripate. 

 dot. S. E. Siberia and Japan; Leech erroneously recorded a Japanese example as blomeri var. 



D, marmoraria Leech (13 f) differs from blomeri in the pencilling of zigzag black lines in the median area marmora- 

 of the forewing, antemedian and a group of 3 postmedian strongly bent so as to meet on the fold, an oblique ''"^■ 

 discal streak, some blackish distal clouding behind the 3'"'' radial, followed posteriorly by a double dentate line. 

 Abdomen anteriorly with a dark dorsal blotch. A close ally, if not a variety, of the Indian obliquisigna Moore, 

 but with darker hindwing, etc. Chang-yang, Central China. 



D. laria Oh. (8b). Larger than marmoraria, median area less white, the reddish colour in distal area lariu. 

 not forming a subapical patch but confined to a narrow band adjoining the postmedian, from costa to P' median; 

 hindwing paler grey with 8 pairs of dark lines. Ta-chienju. Perhaps another form of ohlujuisic/na. 



D. meg^aspilata Warr. (7 g, lie) is characterized by the large, obliquely placed black discal mark ofmegaspilata. 

 the forewing. Whitish, the forewing with scattered fuscous irroration, the antemedian and postmedian lines 

 fuscous, double (the postmedian often triple), angulated near the costa, then nearly vertical but irregularlv 

 dentate, slightly convergent towards the hindmargin. Hindwing white, weakly marked, but with a few black 

 dots at inner margin in distal half. Japan: Gifu. 



D. eucosma sp. nov. {= kioudjrouaria Leech nee Ob.) (12 c). Larger and whiter than megaspihda, the cucosma. 

 discal dot not quite so large, the 3 postmedian lines rather well expressed, mostly filled in with brown shading, 

 crossed by strong interrupted black lines on the veins; the antemedian line often single, placed quite near the 

 discal dot, not angulated, black at cosia and marked distally with fine black teeth on the veins. Hindwing 

 white, with 2 or 3 very fine lines (sometimes obsolete, at least anteriorly) distally to the cell-dot. Forewing 

 beneath smoky, hindwing white; the markings of the upper surface indicated. How-kow, Tibet. Type and 3 

 others in the British Museum collection. 



D. kioudjrouaria Ob. (8b). I have not seen this, but cannot believe it is conspecific with the preceding, kioudjrou- 

 in spile of much similarity. The forewing is shorter and blunter, its colour grey, the discal dot small, the °""*^' 

 antemedian line approaching the postmedian on hindmargin, whereas in eucosma it here turns obliquely base- 

 wards, the postmedian less sharply angled near the costa, the band which accompanies it less sharply expressed, 

 not marked with black on the veins. Hindwing also more greyish white. Ta-chien-lu. 



B. Hindwing in d^ with inner margin deeply folded. 



D. dhartnsalae Btlr. (= plicataria Leech) (7 g, as plicataria). Reddish brown with slight darker irroration. dharmsalae. 

 Forewing with the veins partly dotted with fuscous, pale between the dots; numerous very feeble, parallel, 

 wavy darker reddish lines, the antemedian a little better expressed; only the postmedian distinct, double, the 

 proximal one grey, the distal reddish, some lighter grey shading between them. Hindwing similar, without the 

 lines of basal half. Underside paler, forewing with discal dot and lines beyond, hindwing unmarked. N. W. 

 India; W. China. 



69. Genus: Af^tliena Hbn. 



Characters of Hi/drelia but with the areole double. Palpus sometimes rather less short than in the 

 allied genera. Distal margin of hindwing often somewhat crenulate or angled in middle. 



Larva (at least in the type species) rugose and tumid, but evidently related to Hydrelia. 

 Geographical range as in Hydrelia.
