of corsalta, but tlie S valve is broader distally (more shovel-shaped), with 3 or more pointed projections at the 
end, where cor salta has 2 only and efformata is rounded. 
A. efformata Guen. ( = pallidata Stgr.) (9 a). This widely distributed Analtis, though erected as a efformata. 
separate species by Guenee, was subsequently degraded to the rank of an aberration, or at the best a local 
race, and I regret to have to acknowledge that —■ misled by the superficial similarity of some slender-banded 
plagiata of the 2nd brood — I too dogmatically asserted (Vol. 4, p. 177) that it “certainly” had no claim to 
be a good species. Strangely enough, no-one seems to have noticed the very different form of the abdomen 
(shorter and much less pointed, particularly in the <$) until 1923, when Dr. K. Jordan, in examining the series 
in the Tring Museum, was gradually led to discover the true state of affairs; see his interesting account in 
Novit. Zool., Vol. 30, p. 243. The S valve in plagiata is at least 6 times as long as its greatest width and ter¬ 
minates in 2 small points (shorter than those of cor salta) ; that of efformata is relatively short and broad, elbowed 
in the middle and with other conspicuous differences. Superficially, the majority of efformata can be recognized 
by their smaller size, on an average paler coloration, generally slightly straighter antemedian band of the 
forewing, perhaps more obtuse subcostal angulation of the postmedian and other small points, but no infallible 
distinction has yet been found in the markings. Some entomologists have great confidence in the more acute 
angulation of the subbasal line, but this, though veiy general, is not quite constant. Guenee's type was 
Syrian, Staudinger’s originals came from Greece and Asia Minor; in the Mediterranean subregion the distrib¬ 
ution is very general — indeed in the Iberian Peninsula, Morocco and Algeria efformata seems to oust plagiata; 
but in England, France, Central Europe, Sweden, etc., the two may often be found together; efformata is not yet 
known eastward of Asia Minor. In England it loves chalky hillsides and is more local than its well-known congener. 
The early stages of the two are extremely similar; both larvae have the same markings and the same curious 
truncated anal flap, but plagiata is of a richer, redder brown colour (Cockayne in litt.). Dr. Cockayne re¬ 
cords that from the 2nd brood (August) eggs were laid freely on Hypericum perforatum, usually singly but 
sometimes in pairs, on the petals, sepals and small leaves; they are pale cream-colour, smooth, ovoid, flattened 
on the side of attachment. The newly hatched larva is long and thin, whitish with a narrow blackish dorsal 
and subdorsal line, and another interrupted line below the spiracles; collar narrowly white; head pale yellowish- 
brown with a black spot on the lower part of each lobe and black mandibles; legs speckled with black. It feeds 
readily on the plant named. — ab. fasciata Hannemann has the entire median area of the forewing darkened fasciata.

plagiata. The only infuscated efformata yet known to me is the beautiful S here figured, which was taken by 
Zeller on “30. 5. 59”, therefore — according to his manuscripts — at Gross Glogau, Silesia. — Of geographical 
variation in efformata we have as yet little knowledge. The form from the Riff Mountains, Spanish Morocco, 
is according to Reisser, rather large, of an intensive bluish ash-grey colour and sharply marked, suggesting a 
“slightly differentiated local form”. 
A. perelegans Warr. (9 a) is also a good species, with quite different genitalia. We give a figure. It perelegans. 
remains rather scarce, so far as I can judge from the Japanese collections which have come under my notice, 
and few of the specimens have adequate data. 
A. simpliciata Tr. ab. pazsiczkyi Dioszeghy corresponds to plagiata ab. tangens, the central bands pazsiczkyi. 
meeting so as to divide the enclosed light area into a larger anterior and a smaller posterior part. Founded 
on specimens from the Retyezat Mountains, 1900—2200 m. — pierretaria Guillemot (= magdalenaria Bell.) pierretaria. 
(9 b). All the French specimens known to me, as well as the good figure of magdalenaria type, show a more 
brownish-grey (not bluish) tinge than typical simpliciata (S. E. Hungary, Bosnia, etc.), the lines which form 
the two bands of the median area often more widely separated, so as to narrow the pale central part of the 
area. Perhaps also on an average rather large. Discovered in the Barcelonette district (Basses-Alpes). We 
figure a S from Lautaret (Hautes-Alpes). — ab. lantosquata Th.-Mieg (9 b). This name supplants obscurata lantosquaia.

not been able to find that it has yet received a name. Two large $$ from “Altai” in the Elwes collection 
are probably incorrectly labelled. — - graeciata Stgr., accidentally omitted from Vol. 4, was briefly diagnosed graeciata. 
in 1901 as having the forewing yellowish grey, not cinereous, and given as constituting a separate race in Greece, 
though with the cinereous type-form as an occasional “ab.” amongst it. I have only one before me, a <$, 
duller and more drab-grey than even pierretaria. 
A. fraternata H.-Sch. (9 b). In Vol. 4 (p. 178) I was only able to quote the brief diagnosis of this species, fraternata. 
In working out the Geometridae of the rich Peeiefer-Osthelder collection from Marascli, however, Dr. Wehrli 
has found an opportunity to investigate carefully both it and obsitaria , together with the originals of opificata.
