392 GNOPHOS. By L. B. Prout. 



poggearia. G. poggearia Led. (22 f). Larger than dolosaria, similarly coloured but somewhat more variegated. 



Forewhig with apex more acute, hindwing rather more undulate; discal dot of forewing larger, postmedian 

 line usually faintly brown, but chiefly indicated by small blackish veui-dots. Underside much more coarsely 

 dusted than upper. Sj'ria and the Taurus. 



palaesiinen- G. palaestinensis Calberla (22 f). Forewing in ^ with fovea. Pale straw yeUow, densely irorrated 



®'^' with brown ; discal spots present on both wings, on the hindwing indistinct ; lines hrown, the antemedian gently 

 curved, indistinct, median shade thick (sometimes obsolete), postmedian midway between this and distal mar- 

 gin, angulated on the 1st radial, not toothed on the other veins, present (except in costal area) on the hind- 

 wing. Underside yellowish, with the discal marks distinct, that of the forewing large and round, that of the 

 hindwing narrow and elongate, a brown postmedian stripe also present, on the forewing not reaching the 

 hindmargin. This stripe distinguishes palaestinensis from gruneraria. Palestine. 



gruneraria. G. gruneraria Stgr. (25 d). Near poggearia but larger (size of serotinaria), both wings with broad cho- 



colate-coloured, not black-dotted postmedian line. Further differs in its much lighter, dirty yellow underside. 

 Greece: Taygetos, Veluchi. 



lentiginosa- G. letitiginosaria Leech (22 g) is a species quite apart, the broad white wings strongly spotted and 



ria. 



clouded with fuscous, the ceU-spots large hut not oceUated. W. China. 



myrtuiata. G. myrtillata Thibg. (= canaria Hhn., limosaria Esp.) (22 g). A variable species, freqiiently of very 



large size, the $, however, considerably smaller than the (J. I kirow of no species with which it is likely to 



be confused. The name-type is a dark fuscous-grey form which prevails in Scotland, Scandinavia, Russia, 



anastomosis, the Caucasus and Altai, etc. — ab. anastomosis Strand has the markings very sharply black, the antemedian 



obfusciiria. and postmedian lines of the forewing anastomosing behind the middle, then separating again. — obfuscaria 

 Hbn. is a cinereous form from the Pj'renees, the mountains of Italy, etc. In the Alps both forms occur. ■ — 

 nivea. nivea Schawerda is a large whitish mountain form from Herzegovina. — Egg roundish oval, laid with its 

 micropyla uppermost; reddish purple, brightest at the micropylar end, ribbed longitudinally and crossed by 

 numerous rings of transverse ribs. Larva stout, cylindrical, rugose, the 8th abdominal with a pair of small 

 dorsal points; greenish brown or more greyish. On low plants, hibernating. Imago in July, common in many 

 localities. 



sericaria. G. sericaria Alph. {22 g) resembles myrtillata but has the distal margins much more crenulate, the apex 



of the forewing more acute, the wings less opaque, Avhitish-grey. strongly irrorated, the postmedian line removed 

 further from the discal dots, which are smaller. Thian-Shan. 



C. Distal m a r g i n o f h i n d \\- i n g u n d u 1 a t e. Antenna i n (5' b i p e c t i n a t e. {Latascia 



Hbn.: type dilucidaria, Hmps. et Warr. usus. mea sel.) 



sacraria. G. sacraria Stgr. Much smaller than the European species of this group, palpus exceptionally small. 



Variable in colour, grey to grey-brown, fuiely and densely irrorated with dark scales. Forewing with indistinct 

 traces of antemedian line, small but distinct round cell-spot (mostly weakly pale-centred), postmedian line 

 consisting of dots. Hindwing with the cell-sjDot usually weak or obsolescent, postmedian Ime as on forewing. 

 Underside lighter, in the $ white, almost mnnarked except that the forewing sometimes shows the cell- 

 spot distinctly and occasionally a dark postmedian line is present. Palestine, October — ^November. 



adjectaria. G. adjectaria Stgr. resembles luticiliata subvariegata, but is distinguished at once by the pecti- 



nate ^ antenna, cj about 22 — 24 mm in expanse, dull brownish, the discal ring and postmedian Ime not verj' 

 strong, sometimes almost obsolete, hindwing with basal half lighter (dirty white-grey), distal half darker clouded. 

 Underside dirty white-grey, quite weakly marked. 5 larger and lighter. Palestine, November. 



serotinaria. G. serotinaria Schiff. (22 g). Less variable than some of the species, generally distinguishable from the 



two following by its yellowish tone, with brown irroration, lines, and shading before the subterminal (especially 

 at hindmargin). Antemedian line bent outwards in and again behind the cell, thickened at costa and on the 

 veins (in sordaria and dilucidaria nearly straight); postmedian generallj' rather thick, always with marked 

 teeth or dashes on the veins; discal rings large. Forewing beneath more strongly dusted but never unicolorous 

 s-noky, both wings with cell-spot and traces (sometimes distinct) of postmedian line. Hindtibia of ^ dilated. 



tenehraria. — ab. tenebraria F. Wagner ( =dognini Th.-Mieg, aenearia Ob.) is very much more densely dusted (sometimes 

 almost entirely covered) with dark brown. Rather prevalent in the P5Tenees Orientales. — Larva cylindrical, 

 the abdominal tubercles conspicuous, the 8th abdominal with 2 short dorsal points; greenish yellow, with 

 triangular brown dorsal spots. On low plants, hibernating. Moth in July, distributed in the Alps, also in the 

 Pyrenees Orientales. According to Krtjlikovsky, the white form from the Ural which has been recorded as 

 serotinaria is different in shape, etc., and cannot belong here.
