EUPITHECIA. By L. B. Prout.

E. furcata Stgr. (18 c). A $ from Marasch (Pfeiffer expedition) and a lighter $ in the British Museum furcata. 
from Shar-Deresy, N. Syria (here figured) add somewhat to the range of this species. 
E. chalikophila Wehrli (= chalicophila Wehrli) (18 d). Ciliation of the S' antenna a little longer than chalikophila. 
the diameter of the somewhat slender shaft. Palpus over 1*4 times diameter of eye. Wings rather narrow and 
elongate, quite distinct in shape from the variable semigraphata, for which it was at first passed over; areole 
simple. Separable at once from light grey innotata by its much less sharply angled postmedian, strongly spotted 
fringes, etc.; from nanata by its less extreme shape, larger size, somewhat longer antennal ciliation and lack of 
the oblique pale apical shade and of the enlarged tornal white spot of the forewing. Sierra Nevada, locally 
common on calcareous rocks in July. The genitalia demonstrate that its nearest relative is the smaller, less 
sharply marked, more violet-grey hyperboreata of N. E. Europe, though those of the $ suggest a transition to 
innotata and Wehrli proposes, as a better sequence, nanata, hyperboreata, chalikophila, innotata. There can 
be very little doubt that an early record by Staudinger of hyperboreata at S. Ildefonso (Castile), 2000 m 
altitude, on rocky terrain among Erica, referred really to the jiresent species. 
E. gelidata Mdschl. The type of gelidata was a $ from Labrador, but there is every reason to believe gelidata. 
that it belonged to the same species which is distributed in Greenland. Although this is sometimes curiously 
like some dark forms of nanata (see Vol. 4, p. 293) the genitalia associate it with the species which has since 
been named hyperboreata and the occurrence of the typical gelidata in the Palaearctic fauna is very improbable; 
it will be further discussed in Vol. 8, but in order that the Palaearctic subspecies may be understood it must 
be noted that gelidata, though very variable, is definitely a good deal darker and less brownish, the wings 
slightly narrower. — hyperboreata Stgr. (17 h). I follow McDunnough in attaching this to gelidata, though hyperborea- 
it is at least a good subspecies; the aedoeagus quite agrees, the thorn on the lower edge of the valve is very 
similar but somewhat more developed, the saccus seems larger. The foodplant of the larva is Ledum palustre 
(Ericaceae), not “Sedum” as erroneously given in Spuler and in the German edition of our Vol. 4 (p. 293). 
Heydemam discovered hyperboreata in Schleswig-Holstein in 1925, but it was not found there again until 1931. 
E. nanata Hbn. (Vol. 4, pi. 12 k). A remarkable record for this generally monophagous Eupiihecia is nanata. 
that L. Joannis reared it on apple. — ab. pauxillaria Bsd. To this is to be added as a synonym obscurata Stgr., pauxillaria.. 
diagnosed without locality in 1871. — ab. mediofaciata Dietze ( = nigrofasciata Dietze). Median area of fore- mediofaciata. 
wing more or less strongly blackened. Founded on a well developed example from the Taunus (with white 
central spot) and one bred from Rhein-Hessen which ‘"looks alb in otic-anaemic”. It does not seem to have 
been remarked that Hubner's original figure of nanata nearly approached this form. — angusta nom. nov. angusta. 
(= angustata Haw., praeocc.) (17 k). Wings narrower, the forewing very lanceolate, of a purer grey and with¬ 
out admixture of reddish or yellowish; angulation of the last pale band generally more acute; extrabasal line 
much more elbowed, more oblique, straighter; the threads which traverse the bands very distinct” (Guenee). 
This our most usual English form is, I am informed by Dr. Debaitche, constant in Belgium, perhaps there 
even more absolutely without brown admixture. — ab. oliveri Prout. Forewing almost entirely black, with oliveri. 
a tinge of brown, especially in the parts which show that colour in typical forms; faint traces of the white post¬ 
median band and extremely slender subterminal line. Hindwing equally black posteriorly, a little less so 
anteriorly; subterminal weakly indicated. A few bred at Wolverhampton. — zebrata Wolff. Average length zebrata. 
of forewing 10 mm. Ground-colour whitish grey, the forewing with sharply-marked dark fuscous basal patch, 
ante- and postmedian bands and partial median and submarginal, the last-named interrupted by the ground¬ 
colour between its main part and its (more proximally placed) costal spot; the pale subterminal line coarse, 
serrate. Hindwing beneath whitish, with 3 dark bands. Faroe Islands, a good local race, the genitalia typical. 
— kozhantschikovi Wehrli (18 d). Large to extremely large (length of a forewing about 11 % to 13 mm), very kozhantschi- 
weakly marked and altogether so similar to some forms of innotata that, without a study of the genitalia, they kom. 
had actually been referred there. Djakonov at first determined them as innotata f. grisescens and it seems 
highly probable that even some of the forms figured by Dietze as belonging to innotata properly belong here 
(e. g. perhaps corroborate) ; if so, of course a correction of the synonymy will be necessitated, but for the present 
it must remain unaltered. Minussinsk, in two generations, May (very large) and August (much less large). 
E. pliniata Stauder, a puzzling $ from Boscoreale, Sorrente Peninsula, S. Italy, 450 m, captured on pliniata. 
21 June 1928, looks (as Dietze says of 5 second-broocl nanata from S. Tyrol) “like a cross between innotata 
and nanata” . Unfortunately it is not in perfectly fresh condition. In the relatively weak markings (both 
wings) and rather uniform greyish tone it suggests at first sight a small innotata and the form of the post- 
median line anteriorly is more as in that species, perhaps also the elongate cell-mark. Size, shape and the 
complete subterminal line (though a trifle less angulated near costa and near tornus) as in nanata, but with 
the oblique dash from apex scarcely discernible; with attention, the double whitish line outside the post¬ 
median, the interrupted blackish marks on the veins, and on the hindwing the principal markings of nanata. 
are clearly visible; postmedian line closer to the cell-mark than is usual in either this or innotata.
