EUPITHECIA. By L. B. Prout. 



Issyk-kul, etc., is essentially paler, but is founded on captured specimens. — Larva on flowers and seeds of 

 ' Atriplex and Chenopodiiim. Imago at the end of June and in July; the name-typical form distributed in 

 Europe and Asia Minor. 



druentiata. E. druentiata Dietze. Another doubtfully-placed species with double areole. I have no material, but 



according to its author it shows a remote resemblance to millefoliata ; more coarsely scaled, the coloration 

 still more irregularly composed of dark and light elements "as if sprinkled with pepper and salt". Discal spot 

 larger and deeper black, fringes more strongly chequered. Veins in the distal part of the median area marked 

 with dark streaks. Underside similar to that of arceiUhata, but more strongly dusted with whitish and blackish. 

 Body robust; abdomen with brownish belt dorsally. Larva on flowers and seeds of Artemisia camphorata. 

 Moth in May — June, only known from Southern France and Istria. 



marginata. E. marginata Stc/r. is probably related to subnofata, agreeing in build, ground-colour, in the scarcely 



indicated discal dot, light, scarcely marked hindwing, weakly marked underside, etc. But it shows, like icterata, 

 a sharply differentiated, rather broad grey costal stripe on the forewing. A silky gloss is manifest on the 

 wings. Lebanon, Taurus, Transcaucasia and the Hi district. 



bella. E. bella Stgr. is said to differ from all the other species in the clear lij^ht chestnut brown ground- 



colour of the forewing. Costal margin with dark and white strigulation, two whitish spots distaUy to the 

 cell-spot, the first indicating the beginnings of two whitish lines, the second large, separated from the first by 

 a quadrate blackish spot; a black, white-bordered spot near anal angle; the usual transverse lines indicated. 

 Ussuri: Sutschan district. 



suhtiliata. E. subtiliata Chr. appears to be similar to the preceding but perhaps longer winged, the ochreous lines 



still weaker, only two in the middle darker, right-angled anteriorly, enclosing a small indistinct discal dot. 

 N. Persia and Transcaucasia.

E. suboxydata Stgr. (I3i) represents a variable species, or group of species, of which the life-history 

 is not yet known. Nearly of the size of suhfiihata, wings narrower, especially the forewing, less sharply 

 marked. The lines of the forewing, so far as recognizable, seem less waved or dentate, 3 blackish lines stand 

 close together near the base, the subterminal is rudimentary, not dentate, but broken up into dots or short 

 streaks. Hindwing dark grey. Possibly, according to Dietze, related to druentiata. The name-typical form, 

 from the Amur and Ussuri district, is grey. ~ minorata Dietze is smaller, likewise grey but more sharply 

 marked ; median area darkened, conspicuously light-bounded distally. Hi district. — • subbrunneata Didze, from 

 Aniurland, is a large, strongly brown-tinted form, sometimes almost without markings, excepting the black 

 cell-spot. Possibly a separate species. — amita Dietze is a brownish-grey form from Koko-Nor, but as it seems 

 to differ appreciably in the cf genitalia it will probably have to be raised to specific rank. — pallida Dietze, 

 from Aksu, seems to be a somewhat paler desert-form of amita and is perhaps not worth naming. — cinna- 

 momeata Dietze may also be a form of amita. Smaller, duskier; more sharply marked with brown. From 

 East Turkestan and the Hi district. — patruelis Dietze is a doubtful form, reminding superficially of vulc/ata, 

 from which it is at once distinguishable by the shorter palpus and more strongly chequered fringe. 

 Korla. -- moecha Dietze is probably, according to the appearance of the cf genitalia, another distinct species 

 of the suboxydata group. Dietze was at first inclined to refer it provisionally as a form of the sharply white- 

 marked bella Stgr. but it is superficially more like absinthiata on account of its uniformly brown colour. Sarepta 

 and Uralsk. I have no personal knowledge of the species of this group. 



sinuosaria. E. sinuosaria Ev. (12 m) is a striking species and very easy to distinguish among the European forms, 



its closest allies (or representatives) being Asiatic. Only to lanceata does it bear even a general resemblance 

 and from this it differs so considerably in its less elongate wings, darker, richer and more varied coloration, 

 etc., that a detailed comparison is unnecessary. Areole double. The range extends from Konigsberg (Prussia) 



.pallescens. through Eastern Europe to Central Asia. — pallescens Dietze is pale clay-coloured, even the brown and blackish 



parts of the type only becoming dark clay, the discal spot alone remaining blackish. It seems also rather 



shorter-winged; yet it is connected with the name-type through the following form, pallescens is known from 



modesta. Aksu and Yarkand. — modesta Dietze, from the Alai Mountains (Ferghana) is intermediate in coloration between 



obliquarin. simwsaria and pallescens. — obliquaria Leech is probably nothing more than a large, sharply marked form of 

 sinuosaria; the blackish blotch between the radials, extending from the subterminal line almost to the post- 

 median, and thick black marks on the veins distally, between this blotch and the termen, are very conspicuous. 

 Ta-chien-lu, W. China. In one of the two examples the dividing-vein of the areole is obsolete. — Larva on 

 the flowers of Atriplex and Chenopodium. The pupa hibernates, producing the moth about June.
