•2:30 ARCHANARA. By W. Warren. 



desertieola. A. deserticola Stgr. (49 e). Forewing uniform sand colour, not darkened towards termen as in 



phragmitidis; underside blackish grey, with the margins pale; hindwing greyer, with a faint dark cellspot, 

 outer line, and submarginal shade. Biskra. Algeria. 

 modexla. A. modesta Stgr. (49 e). Extremely close to the preceding (deserticola) and perhaps a local form 



of it. Forewing of the same sandy colour, but thickly strewn with blackish atoms: hindwing dark grey, 

 with the fringe paler, yellowish; costal area yellowish. Palestine. 



mabillei. A. mabillei Lucas (49 e). Forewing fulvous, unevenly dusted with black atoms; outer line very 



distinct, brown, dentate, incurved below middle; a fuscous streak from base to termen along middle of 

 wing between veins 4 and 6; hindwing grey, with a faint darker outer line, before which the wing is 

 partly fuscous. Described from 3 examples from Algeria. Quite a small species. 

 fluxa. A. fluxa Hbn. (= junci Bsd., helmanni Guen. nee Ev., extrema H. Schaff. nee Hbn., saturata Stgr., 



expressata Krul.) (49 f). Forewing rufous, dusted with grey whitish; the rufous tint clearer along the 

 two folds; the costa and veins dotted grey and ochreous; orbicular and reniform of the ground colour with 

 pale outlines, the orbicular round or elliptical, the lower lobe of reniform dark; outer line indicated by a 

 hellmanni. curved row of dark pale-tipped spots on veins; hindwing pale grej'ish luteous; the form hellnianni Ev., 

 by which name the insect has hitherto been known, is sandy ochreous, dusted with darker, with very 

 pulverosa. little or no red tinge; ah. pulverosa ab. nov. (49 f), has the grey dusting very strong, the dots of outer line 

 obsolete, and the veins dark. Recorded from S. Sweden, Finland, Holland, Britain, N. Germany, Bo- 

 hemia, Austria, the Ural Mts., and Issyk-kul, Turkestan. Larva bone colour, dorsally tinged with red, 

 whiter below; the spiracles black; head glossy, yellowish brown; thoracic and anal plates paler; feeding low 

 down in the stems of Calamagrostis epigeios in marshy districts; pupating in a slight cocoon in the ground. 

 pygmina. A. pygmina Haw. (= fluxa Dup. nee Hbn., extrema H. Schaff. part nee Hbn., hellmanni H. Schaff. 



fig. 339 nee Ev.) (49 f). Forewing rosy red, or bright brick red without markings; hindwing pale grey: 

 abdomen whitish with rosy anal segment; the $ of this form is dull pink, with the costa and all the 

 veins broadly dark grey and sometimes a trace of the dark outer line of dots; hindwing darker grey; 

 fulva, in neither sex is there any tint of yellow or fulvous; the form fulva Hbn. (49 f) is fulvous rufous with the 

 ochracea. veins and outer line of spots dark, especially the median vein; — ab. ochracea Tutt (49 f) is yellow 

 ochreous. without red tints, the outer line of dots marked, and often the median vein and the other veins 



punicea. towards termen; ab. punicea Tutt (49 f) appears to be a paler and greyer, less fulvous, form of fulva; 



pallida, while pallida Stph. (49 f, g) is pale ochreous or bone colour with the costa and veins dark grey and 



generally a dark shade running below the median vein; this form occurs of two sizes; the larger form may 



/ ."" t ".^ a ' possibly represent the ab. neurica Stph. (non Hbn.); ab. transversa Stgr. is distinguished by having the 



/asciata. inner and outer lines complete and fully marked across the forewing, which is dark grey; ab. fasciata ab.nov. 

 (= ab. 1. Hmps.) from Algeria also has the lines entire and dentate, with the median fascia strong, but 

 the ground colour pale ochreous instead of grey. Spread throughout North and Central Europe and 

 occurring in Armenia. Larva dirty white, showing sometimes two or three dull flesh-coloured lines; dotted 

 and in parts streaked with darker; sometimes dark flesh colour with yellowish dorsal line and reddish 

 grey brown lateral lines; feeds in lower part of the stem of Carex paludosus (and ? Poa aquatica), 

 pupating in situ. 



extrema. A. extrema Hbn. (= concolor Guen.) (49 g). Forewing bone white slightly dusted with grey, with 



no markings except the outer, much curved, row of dark vein-spots and some black terminal spots; hind- 

 wing pale grey; in shape of forewing agreeing with fluxa Tr.; the imago emerges in the latter half of 

 June, whereas fluxa and pygmina appear only in August and September respectively. Found in Britain, 

 Germany, Austria. Hungary, S. Ural Mts. and in Turkestan; Larva probably in roots or lower part of 

 stems of Molinia coerulea. 



morrisii. A. morrisii Dale (= bondii Knagys) (49 g). Larger than the preceding species, chalk white, with 



faint grey dusting towards termen in the gtf; a curved series of black vein spots represents the outer line; 

 no marginal spots; hindwing dark grey, paler in $; the fringe white; the abdomen is longer and thinner, 

 the pectus and palpi smoother, less woolly, than in extrema. Found only on the South coasts of England 

 and Greece. Larva in the roots of Arrhenatherum elatius. 



111. Genus: Arclianara ]\'alk.

 of <$ ciliated; palpi porrect. the second segment long, rough-haired; prothorax slightly crested: abdomen 

 long, without crests; stout in the $, ending quadrately in the ^; larva elongate, feeding within the stems 

 of marsh-growing Gramineaceae, and pupating in situ, usually with the head upwards. Type Arclianara 

 pnlita Walk, from China. 



""", ',!)'" A. geminipuncta Haw. (= guttans Hbn., paludicola Hbn. f. 637, arundinis Sepp.) (49 g). Forewing 



reddish fuscous, with a broad paler space along the inner margin; the reniform stigma with two white 



pallida, spots; hindwing fuscous; the ground colour is very variable; — in ab. pallida Tutt it is reddish-or greyish-
