tip) and the longer costa (its tip extending just beyond the end of the valve), which moreover lacks the “thumb¬ 
like process’’; these characters are often easily observable without dissection, by the removal of hair and scales. 
C. dichela sy. n. (4 d). Another striking discovery, unfortunately very variable, therefore even more dbhda. 
difficult to deal with until more material has been amassed. Again outstandingly distinct from all other Palae- 
arctic Calothysanis in the genitalia, which come close to those of the Indian obsoleta Warr., though not identical. 
In addition to the strong lateral plate before the uncus, one observes the very long costa, at its distal end 
strongly upcurved (to about 90 °) and knobbed at its extremity, the fibula fused to the ventral edge of the 
rather narrow valve, only becoming free and conspicuously chitinized in its distal part as a very slender sub¬ 
parallel process; aedoeagus with a pronounced cornutus, a rare feature in Calothysanis and not found in ob¬ 
soleta. The typical form, from S. Ussuri in August, is confusingly like ayicirosea, the oblique line rather broader, 
more diffused at its edges, it and the apical cloud more mixed with smoky grey, the terminal line perhaps less 
slender, the angulation of the postmedian line of the hindwing usually very weak, the fringes somewhat suf¬ 
fused proximally. Type <$ from Narva, 9 August 1921 (N. Kardakoff), now in the Joicey Collection; of 
the first generation I have only seen one Ussuri example (Okeanskaya, 23 June, G. Kon), larger but other¬ 
wise similar. — f. tenuistriga nov. perhaps constitutes a race in Japan, though I know at least one Japanese teumslrlga. 
example which almost reverts to the type form, tenuistriga closely resembles moderately large comytaria, but is 
distinguishable (whether constantly?) by the noticeably less angled postmedian of the hindwing. As type I 
have selected a Tokio <J, June 1891 (Dr. Fritze) in the Tring Museum. — f. pusilla nov., from Gensan, Corea, pusilla. 
in July, is apparently a local modification of the 2nd generation. Small (25—30 mm), less irrorated and of 
a more oclireous tone, the oblique line slender (as in tenuistriga), the postmedian of the hindwing sometimes 
more angled than in the other forms. A Formosan relative, in which the uncus resembles ayicirosea, the valve 
dichela, will be described in Vol. 12. 
C. correspondens Hmys. (Vol. 4, pi. 7 e) is still known from no Palaearctic locality except the Punjab, correspon- 
but as I have received it from N. E. Burma near the Chinese frontier it is still possible that it may be found 
in the mountains of W. China. It remains the only known Calothysanis with straight antemedian of forewing 
and postmedian of hindwing. Apparently not variable. Uncus aborted; valves, etc., difficult to describe, very 
complicated, very distinctive. 
C. convectaria Walk. (Vol. 4, pi. 7 e), though nearer in markings to amata, is readily distinguished from convedaria. 
all Palaearctic Calothysanis by its ochreous tone and especially its dark costa and fringes. I have seen a few 
further examples from Szechuan, but its principal area of distribution is N. India and via S. China to Kago¬ 
shima, the Riukiu Islands and Formosa.

C. oligoscia Prout (4 d). A moderate-sized or fairly large species, rather variable in ground-colour oligoscia. 
(greyer or more ochreous- or fleshy-tinged) but hardly otherwise, the irroration never heavy, the oblique line 
slender; costal margin of forewing somewhat darkened proximally, but far less conspicuously than in the two 
preceding species; postmedian line weak, on hindwing bent, but less strongly than in convectaria-, fringes con- 
colorous^the tips (less than ( 4 ) tinged with pink, underside strongly irrorated, in cell of forewing dark-suffused. 
Genitalia remarkally asymmetrical, the right sacculus short, the left long; fibula with a strong terminal plate, 
armed at end with extremely irregular teeth. We figure the type from Vrianatong, Tibet; many other examples 
are now known from W. China, a few from N. E. Burma. — ab. ponipalis nov. (? sp. div.) (4 c). A remarkable pompalis. 
contrast to the normal oligoscia, among a very long series of which it was taken at Tse-kou. Slightly dif¬ 
ferent in shape, much more irrorated, antemedian present, postmedian faintly double, oblique line thick, 
especially at apex. I would suppose it a species but that the genitalia seem to agree.

to the same species as the typical forms. The oblique line is entirely wanting, while the postmedian (in the 
type represented only by vein-dots) is considerably strengthened and a dark apical clouding is developed above 
and beneath. Nanning, Central China, April 1919, a <$ in the Tring Museum, received from Schmiedel. Per¬ 
haps a race, perhaps merely an extreme aberration. The genitalia seem to agree completely. 
12. Genus: I*t©eliopliyle Warr. 
Evidently related to Calothysanis, according to the evidence of the genitalia. Except in the smaller 
size of the species and the more diversified shape and markings, there is little to distinguish it from Synegiodes. 
The suggestion offered in Vol. 4 that the species miniosa Warr. might occur in the Palaearctic Region has not 
received any further support and it is not unlikely that even in Shanghai (if that w'as actually the Chinese 
locality) its introduction was accidental, perhaps by commerce.
