rated. Underside similar, but with the bands paler. Foretibia with a single claw. Hindwing with costal not 

 anastomosing, 2nd subcostal not stalked. Tarsi not described. Kan-su at the end of June. 



A. hedetnanni Chr. (25 h). Broader winged, 1st line bent inwards behind the subcostal vein, distal hedemanni. 

 area with soma large brown blotches. Hindwing with large vague cell-spot and strong distal cloudings. Fringes, 

 strongly chequered. Underside similar, hindwing less infuscated. Fore-tibia with 2 claws. Hindwing with 

 costal anastomosing, 2nd subcostal stalked. Transcaspia. — mabillearia D. Luc. (= marmorata B.-Haas) is muUUeurla. 

 probably nothing more than a local form of the preceding, agreeing entirely in shape and structure, but lighter, 

 especially the hindwing, which has not the fringe chequered. Said, however, to be very varia,ble. — ab. alba D. aiba- 

 Ltic. lacks the distal blotches of mabillearia. Both these forms inhabit Tunis. I fmd that ,,Lithostege" marmorata. 

 mentioned on p. 175 as unknown to me in nature, is nothmg but a synonym of the present species and must 

 there be entirely deleted. 



A. punctistrigaria Chr. is unknown to me. Forewuig whitish, more or less irrorated with fuscous, with pinwUsiri- 

 3 rows of fuscous spots and a short apical dash. Hindwing greyish, distally infuscated^ inner margin with 2 (/ana. 



fuscous spots. Askhabad. 



144. Genus : l^farragja Walk. 



Face with appressed scales. Palpus with long projectmg hairs. Tongue weak. Antenna of cJ bipectinate 

 to apex. Foretibia without claw. Wmgs narrow, erected in repose. Forewing with 1st — 2nd subcostal coin- 

 cident, anastomosing or connected with costal and with 3rd — 4th subcostal. Hindwing with costal anastomo- 

 sing with subcostal (in nelvae closely approximated), 2nd subcostal stalked with ist radial. Only 2 species 

 yet known. 



N. fasciolaria Hufn. (= cebraria Hbn., zebraria Dup.) (23 d). Very variable but easily known by its iasciolaria. 

 shape, structure, the light, dark-spotted fringes and varied underside. The latter is generally yellow brown with 

 rather darker bands and with white spots, those of the forewing confined to the costa and hindmargin (that 

 at apex purest white), the hindwing in addition with a distal row and elongate ones m the cell and along the 

 radial fold. The name-typical form (though varying) is local in Central and S. Europe, Asia Minor, Central 

 Asia and according to Statjdingek Amurland and N. Chma. — tessularia Metzner (= baltearia Frr., atro- tessularia. 

 macularia H.-Sch.) (23d) is smaller, whiter, with sharply blackish bands. Ural and as an aberration (?) in 

 S. Hungary and Transcaucasia. — fumipennis suhsp. nov. is rather small and narrow-winged, upper surface fumipennis. 

 uniform smoke-colour, only the fringes normal, forewing beneath smoke-colour with yellow costal spots and 

 apical band, the latter continumg (but narrowing) to just behind the 3rd radial, hmdwing beneath yellow with 

 indistinct dark bands, darkened where they pass between the elongate light spots of the cell and radial fold. 

 Pekin in August, one only (a (J) Imown to me, in coll. Brit. Mus. Perhaps a species, as the palpus appears shorter, 

 but Hbbz mentions Pekm specimens as agreeing with the darkest European; intermediate aberrations occur 

 in Europe and Alphbeaky mentions one from Kan-su. — Larva slender, smooth, green, with white Imes, the 

 dorsal finely dark-edged. On Artemisia campestris. The pupa hibernates and the m.oth is double brooded. 



N. nelvac Rothsch. (23 d). Closely similar to fasciolaria, but easily separated by the broader wings and nelvae. 

 the neuration. Algeria. 



145. Genus: Istiirgia Hbn. 



Face with strongly projecting hairs or tuft. Palpus moderate, with long projecting hairs. Antenna 

 in 1^ with short or quite moderate pectinations. Femora slightly or scarcely hairy. Forewing with fovea; 

 1st — 2nd subcostal coincident, generally connected with costal by a short bar near their base (vestige of 1st 

 subcostal?). — Larva of moderate proportions, nearly cylindrical, smooth. The moths fly in the sunshine and 

 commonly rest with the wings closed over the back in the manner of butterflies. Occurs in the Palearctic and 

 Nearctic Regions. 



I. carbonaria CI. (= picearia Hbn.-Gev., atomaria obsoletaria Stichel nee Zett.) (23 f). A pretty and carbonaria. 

 distinct species, white with dense blackish dusting and narrow blackish bands, all angulated outwards in the 

 middle. — ab. roseidaria Hbyi. has less dark marking and the white groi;nd mixed with yellowish. Prevalent roseidaria. 

 in Lapland. — Larva convex above, carinated laterally, dingy brown, rather paler ventrally, a pale lateral 

 stripe dark-edged above, a broad pale medio-ventral stripe. Has been reared on birch and sallow, probably 

 also eats low plants. The pupa hibernates. N. Europe, the Alps and the mountains of Silesia, flying in May 

 and June.
