CIDARIA. By L. B. Prout. 
postalbaria. C. postalbaria Leech (Vol. 4, pi. 13 n) occurs also in the wonderfully rich district of Ta-tsien-lu. Stern- 
eck calls attention to the presence of small semilunar abdominal crests and tufted end of abdomen in addition 
to the large thoracic tuft. He also provides a detailed description of the underside, which is more smoky than 
the upper. 
Subgenus Trichoplites Swinh. 
Face nearly smooth, slightly rounded-prominent. Palpus short or quite moderate. Antenna of 
simple. Forewing with areole double, on the underside in the $ with a ridge of hair in the cell, or more dis¬ 
tributed but more appressed hair. Discocellulars of hindwing in the type species (cuprearia Moore) biangulate. 
A few species, almost exclusively Himalayan and Chinese, are provisionally associated under the above name. 
A. Hair of $ forewing beneath distributed. 
latifasciaria. C. latifasciaria Leech (Vol. 4, pi. 13 c) was founded on a $ from Wa-slian, W. China and the A was 
only recently made known. Dr. Wehrli has one from Kunkala-shan and Lord Rothschild one from “W. 
China”. This is somewhat smaller than the type $ and scarcely a true Trichoplites , as the hairiness of the 
underside is vestigial; yet the head, wing-shape and pattern show unmistakable phylogenetic connection. 
The sex-hair is well developed in its Indian relative, lateritiata Moore. 
B. Hair o f A forewing beneath concentrated in the cell (Trichoplites). 
cuprearia. C. cuprearia Moore (15 h). Easily distinguished from latifasciaria by the structural characters (bi¬ 
angulate discocellulars and ridge of hair), as well as by the pattern. Typically it belongs to N. India (Sikkim 
to Upper Burma). I have seen it from S. Szechuan if not also from the more Palaearctic parts of that province. 
Subgenus Eulype Him.

ilebilis. C. lugens Oberth. (Vol. 4, pi. 10 d) ab. f lebilis Th.-Mieg is darker, both on the fore- and on the hind- 
consolabilis. wing, and is the form figured by Oberthur, Ft. Ent., Vol. 18, pi. 3, fig. 38. Ta-tsien-lu. — consolabilis subsp. 
nov. (15 h). Variable, but distinguishable at a glance, at least in the <§. The white ground-colour lacks the 
creamy tinge which is so general in lugens, the principal veins are slenderly blackish, the black subterminal 
dots of the hindwing well developed. Forewing of <$ with more white in proximal area, sometimes entirely 
white except extreme base and costa; black postmedian band more or less narrowed, occasionally scarcely 
more than a line. Hindwing often with terminal band broken into spots. Yunnan: Mekong-Yangtse Divide, 
E. of Tse-ku: Pei-ma-shan, 14 000 feet, July 1922 (Prof. J. W. Gregory), 9 <$$, 1 type in the British 
Museum. The $ is decidedly smaller. 
hccate. C. hecate Btlr. (Vol. 4, pi. 10 d) is shown by the genitalia to be a distinct species from all the following 
sachalinen- three, notwitstanding some erroneous citations in the American lists. — sachalinensis Matsumura (15 i), des- 
SIS ' cribed from 2 $o, S. Saghalien, is “much smaller (34 —36 mm), the white band broader, with one more black 
tooth at the outerside, i. e. in interspace 6”, on the hindwing broadest in the middle, with a blunt tooth outward 
in cellule 3. The Yezo form of hecate closely approaches it. 
chinensis. C, chinensis Leech (15 i). We figure a fairly typical from Pu-tsu-fong. As a rule the variation is relat¬ 
ively slight, chiefly in the direction of an increase of white subterminal maculation of the forewing. The geni¬ 
talia deviate little from those of hastata and would probably have been regarded as subspecific only but for 
the occurrence of a nearly typical form of hastata in the same district (Ta-tsien-lu, etc.), on which see below. 
Mr. A. H. Stringer writes me that the extremity of the sacculus arm in the two examined is a trifle broader 
than in most hastata forms and the (2) spines on the aedoeagus are constantly longer than in that species”. 
hastata. €. hastata L. (= betularia Gladb., nec L.) (Vol. 4, pi. 10 d) (15 i). On the geographical variation of 
this attractive species and the following there is doubtless still work to be done, but the essentials are at last 
pretty well understood. Both have an extremely wide range in the Holarctic Region and will be further con¬ 
sidered in Vol. 8. The individual variation of both has led to a multiplication of names and I have perhaps 
demolita. not apportioned them all accurately between the two. — ab. demolita Prout (= reducta Osthelder). 1 was 
taken at Schleissheim (S. Bavaria) with several ab. laxata (Vol. 4, p. 254) and was regarded as a new form, 
subalbida. but quite agrees with ray type (Barrett. Lep. Brit., Vol. 8, pi. 336, fig. 1 c). — ab. subalbida Marschner has 
the black of the marginal area greatly reduced, especially on the forewing, where there remains only, 
outside the median band, a narrow section of the subterminal band, from hindmargin about to 1st median 
vein. Riesengebirge, 1 §, at 900 m, the highest altitude there reached by hastata and not far below the first

Forewing almost normal; hindwing wholly white, excepting a small, irregular costal patch and some very
