CIDARIA. By L. B. Prout.

The flight-time extends at least to the middle of July, indeed most of the specimens before me are dated from 
that month, while the northern race probably does not begin to emerge till well on in June and continues into 
August. Hubner's type was a large, pale <$ (though probably figured too white), with rather broad median 
area. — ab. stenotaenia Dcmnehl has the median area of the forewing strongly narrowed, so much so in the posterior utmolacnia. 
half as to consist merely of 3 small rings. Davos. — ciudrelaria Dannehl, said to constitute a well-defined geo- cindrelaria. 
graphical race in the South Carpathians at 1400—1800 m, has shorter and broader wings than the typical 
incursata of the Alps, ground-colour light grey rather than brownish, markings mostly very strongly developed, 
the bands often almost black. Hindwing also well marked, but with the cell-dot very small. Perhaps this should 
be referred to monticolaria ? 
C. annotinaria Zett. (= ? polygrapharia Bsd. = septentrionalis Dannehl) (12 a). According to some annotinaria. 
researches which were initiated by Djakonov and have been followed up during the past two years by Heyde- 
mann, several species have been confused as incursata and are well separable by the genitalia. He will, I hope, 
publish a full account, but he has very kindly permitted me to correct the outlines of my classification in the 
light of his investigations. The present species, so far as I know it in its N. Scandinavian forms, is rather 
small, dull and rather uniform in appearance, the markings being less strong than in incursata , the greyish ir- 
roration more distributed. The types of the cited names came respectively from Lapland, Dalecarlia and N. 
Finland. — ab. decrepitata Zett. is merely a darkened aberration of annotinaria , with the markings of the median decrcpiiida. 
area better expressed. The name was applied by Stichel and others to the typical form, but Wahlgren lias 
adjusted the synonymy to Zetterstedt's types. monticolaria H.-Sch. (Vol. 4, p. 224). Herrich-Schaeffer monticolaria. 
stated that his monticolaria was constant in the Alps; it seems to be more sharply marked, but Heydemann's 
studies have not confirmed its existence there and we suspect the originals were from Lapland; probably the 
forms from Murmansk, Leningrad, etc., which D.jakonov refers here, belong to annotinaria. The shape of 
the valve differs considerably from that of incursata. 
C. sajanaria Prout. Dr. Heydemann has examined originals in the Pungeler collection and tells me sajanaria. 
that the genitalia agree with those of the Kamtschatka representative of the group. Although I cannot see that 
they bear out Djakonov's characterization in the other particulars, they have rather sharp cell-dots and rather 
less strong projections of the postmedian line than incursata. It is possible that two of the members of the group 
occur in the Sajan district, as an earlier note by Djakonov reports “ incursata ” as very variable there,

is said to be smaller and narrower-winged than incursata, the ground-colour very pale and the markings weak, 
cell-dot of forewing large, postmedian projecting very little betweeh the 3rd radial and the 1st median. 
C. semenovi Alph. (= lugubris Stgr.) (Vol. 4, pi. 10 d). The type locality is Myn-dyn-scha (Amdo), semenovi. 
but the well-known Koko-Nor form which was described a year later as lugubris shows no significant difference. 
On the other hand ouanguemetaria Oberth. (=? semenowi Sterneck ) (12 a), from Szechuan, is a well differ- ouanguemc- 
entiated local race. This was recognized both by Staudinger (in his original description) and by Alpheraky in tana. 
1897, but I was misled by the synonymy given in the Staudinger-Rebel Catalog into quoting all the three 
names together. Alpheraky" emphasizes the presence of a bronzy suffusion over a part of the subterminal 
line on the forewing beneath as distinctive of the typical race; but the most obvious difference is the increase 
of black in ouanguemetaria , at least on the hindwing above; the median band of the forewing is strongly variable, 
its white central part occasionally as broad as in typical semenovi, generally somewhat or considerably nar¬ 
rower, sometimes incomplete, in extreme cases limited to a small ring around the cell-spot. The specimen from 
Sunpanting, recorded by Sterneck as semenowi (sic) should presumably be referred here. 
C. montanata Schiff. (Vol. 4, pi. 9 d) has perhaps a more extended distribution than was given; the monlanata. 
Tring Museum has a worn $ from “Kuliab, Afghanistan” (Kuljab, S. E. Bokhara) which appears to be identical 
with European forms. Eltringham has used this species as the basis of a very careful investigation and de¬ 
scription of the Geometrid tympanum (Tr. Ent. Soc. Lond. 1923, p. 444). — ab. nigrofasciata Osthelder. Median niyro/ascia- 
band blackish instead of the usual brownish brown; frequently also broadened. Said to be characteristic of 1(1 • 
the lowlands, particularly in dry pine-woods. — ab. pseudolapponica (Schawerda M.S.) Osthelder is the opposite pseudolappo- 
colour-phase, the band weaker and lighter, sometimes almost evanescent, and is chiefly a mountain form. It nica. 
recalls the subspecies lapponicc but is normal in size, etc. — ab. divisa Osthelder has the band more or less broadly divisa. 
pale throughout its central part, after the manner of incursata, or semenovi. This and the two preceding were 
described from the South Tyrol; Schawerda adds the Austrian Schneeberg and North Tyrol for pseudolapponica. 
- ab. candidata Nitsche, a perhaps unique aberration from Piosmos (Pitztal) lacks the median band, which Candida la. 
is only represented by a quite weakly indicated triangular spot near the costa. Apparently a more extreme 
development of ab. limbaria Him., I suppose without the heavy subterminal shades. — ab. feisthamelaria Bsd. jeisthamela- 
is, according to Culot (who figures a fine $ from Seine-et-Oise), a rather striking development of ab. continuata 
Krulik., with the median band broad and bright, the rest of the markings quite weak. Boisduval's type was 
said to come from Sardinia.
