EUPITHECIA. By L. B. Prout. 



niesograni- E. mesogrammata Dietze. "Forewing broad, yellowish grey varied with red-brown, median area bluish 



mala, grey, not constricted as in exadata, to which it is perhaps i-elated". Schahkuh, Persia. 



iiisigniata. E. insigniata Hhn. (= consignata Bkh) (12 e). Forewing elongate and pointed; very characteristically 



marked. Pale whitish grey, the veins finely darkened; the large brown subbasal costal spot or half-band is 

 occasionally continued across the wing; the blackish spot along the middle of costa is confluent with the 

 elongate black discal mark; a further dark brown spot between this and the apex. Larva chiefly on apple 

 but also on stone-fruit, sloe and whitethorn, in May— June, eating the leaves and blossoms. Imago in April 

 and early May, on tree-trunks. Distributed in Central Europe, also recorded from Asia Minor and Kashgar. 



valerianala. E. valerianata Hbn {= viminata Dhl.) (12 k) is glossy grey, the dark lines very weakly indicated, 



only at costal margin stronger, discal dots minute or wanting; subterminal line indicated, generally ending in 

 a distinct spot near hinder angle, which helps to distinguish valerianata from plumbeolafa. Larva on the flowers 

 and seeds of Valeriana officinalis. Hibernates as pupa. The moth flies in May and June and is distributed 

 in Central Europe, Livonia, Finland, etc. 



illaborata. E. illaborata Dietze suggests a dwarfed, pale valerianata but with more elongate wings, affinities un- 



certain. Light grey with a tinge of clay-colour, median area darkest distally and distal area proximally. 

 Variable, discal dots mostly wanting. Aksu, Chines and Korla. 



pahistraria. E. palustraria Dhld. (= pygmaeata Hbn. nd: Bk/i.) (13 f). A very small, rather broad-winged species, 



glossy, dark smoky brown, generally very weakly marked, though a white subterminal dot near the hindmargin 



pseudo- of the forewing is present, often very conspicuous, not rarely repeated in the hindwing. — ab. pseudozibellinata 



zibelHnata. Dietze is more copiously sprinkled with light scales. Larva on Cerastium triviale and aquatica. The pupa 

 hibernates, commonly over two winters. The moth is found chiefly in marshy places and flies in the after- 

 noon. Inhabits Central and Northern Europe, also recorded from Spain (Cuenca) and Amurland (Askold). 



caliginea. E. caliginea Btlr. {= zibellinata Chr.) has been treated as a variety of the preceding but is — as 



Dietze points out — a good species with longer, more pointed palpus, the ground-colour almost black, beneath 

 with the whitish lines more strongly marked. Moreover the wings are rather more elongate and the cf antennal 

 ciliation as long as the diameter of the shaft (in palustraria much shorter). Japan and the Amur-Ussuri district. 



undata. E. undata Frr. (= scriptaria H.-Sch.) (12 k). Dark ash-grey with numerous waved paler transverse 



lines, the most distinct of them grouped in 3 or 4 pairs. Discal dot rather small, longer than wide, often 

 wanting; subterminal line fine, dentate, fringes chequered. Variable in colour. The larva feeds on the seed- 

 pods of Silene rupestris. The pupa hibernates, sometimes twice. Best known from the Alps but also recorded 

 from Central Italy and N. Norway, the Sajan district in Siberia and singly from Asia Minor and Transcaucasia. 

 puengeleri. It is found in July, resting on rocks in mountain districts. — puengeleri Dietze is very likely a separate species, 

 though the o^ genitalia seem to associate it with undata. Superficially very different, more suggesting a relation- 

 ship with graphata. Rather smaller and rounder-winged than riparia, whitish grey with a strong bluish tone, 

 traversed by about 13 very regularly arranged darker blue-grey waved lines, a light, weakly dentate band 

 distally to the median area. Under surface almost uniform pale slaty grey, quite weakly marked; distal margin 

 scarcely darkened, not sharply light intersected, fringes not distinctly chequered. Gudaur, Caucasus, at the 

 end of June. 



leplogram- E, leptogrammata Stgr. Similar to graphata and undata, not so sharply strigulated as in the former, 



7nala. hindwing not so white. A characteristic, though not very conspicuous brown-grey suffusion before and behind 



the 1'' median vein of the forewing, also on the vein-ends; the dentate subterminal line, usually so prominent 



in the allies, is wanting. Underside shining white-grey, distal margin light grey, in the allies mostly blacker. 



Zaisan and Issyk-kul. 



concremala- ^' concremata Dietze is darker ash-grey, less marked, hindwing whitish with strikingly wide, black, 



interrupted marginal line. Sinin, Central Asia. 



inconspi- 



E. inconspicuata Bohatsch. Similar to undata, more slenderly built, lighter coloured, the wings more 

 cuata. elongate. Yellowish grey with dirty white bands, generally indistinct, rather more obliquely placed than in 

 scriptaria. Discal dots very small but (as also the dark terminal streaks) more distinct than in scriptaria. Not 

 rare in Asia Minor and Southern Armenia. 



variostri- E. variostrigata Alph. (13 f). Forewing whitish with numerous oblique, not waved blackish lines and 



gata. here and there in the middle an admixture of brownish which gives to the wing a chequered appearance ; 



discal spot indistinct; subterminal line distinct throughout; fringes weakly chequered. Palpus about twice as
