bounds the distal area rather prominent, with strong teeth on the veins, y smaller, lighter, with median area- 
more sharply marked and cell-dots more distinct. Transbaikal: Malchan Mountains, 800 in. The ^ genitalia 
show a transition towards the tianschani ca subgroup. 
p. 126, after C. deflorata: 
C. hummeli JDjakonov. Nearly related to deflorata, genitalia extremely similar, differing only in small 
details. Length of forewing about 13 mm. thus smaller than deflorata. Pectinations similar. Palpus moderately 
long, pointed. Wings rather broad, with termina somewhat more rounded than in deflorata; white, the liind- 
wing almost unmarked, the forewing with the markings grey-brown, not yellowish as in deflorata; basal area 
apparently with 2 broad grey-brown stripes, curved as in deflorata; median area dark, in the middle mixed 
with white, postmedian more strongly dentate and with stronger projection between 3rd radial and 1st median, 
the white stripe outside it much narrower than in deflorata; subterminal distinct, also more slender than in that, 
but forming some definite lunules between the veins: no distinct terminal line. S. Kansu: Lu-pa-sze on the 
Tao-ho. northern declivity of Min-shan, ca. 2750 m, 1 g; Tsaluk Valley, Min-shan, 1 the $ badly worn, 
the A slightly. 
p. 127. to C. spadicearia . — ab. (?) confixaria H.-Sch. Praviel (Bull. Soc. Ent. Fr., Vol. 41, p. 31) thinks 
that previous authors have been wrong in referring confixaria H.-Sch. to spadicearia and treats it as a separate 
species in the corollavia group. He states that he has seen identical specimens from Syria in the Joantstis col¬ 
lection. 1 have re-examined the original figure and description (of a $ without locality) and admit that it is 
rather puzzling in some details; if it was an imperfact specimen, so that the describer and the artist overlooked 
the break in the middle of the subterminal line, it might almost be a form of the variable taeniata Stph. 
p. 128. to (A ferrugata. fuscata Nordstrom is an unusually dark and unicolorous grey-toned form 
from Pite Lappmark. with little or no brown in the median band. It is anticipated that ampler material will 
show it is entitled to rank as a subspecies in Lapland. alaskae Cass. <f> Swett, from Alaska, published 10 years 
earlier than fuscata. deserves notice, as it is just possible that there is a “Holarctic” circumpolar race for which 
this would be the oldest name. The authors find the genitalia more as in the European than in the other American 
forms (inclinataria Walk.). Like fuscata, it is described as much darker and more uniform in colour than the 
typical, but I suppose it to be browner; both wings are “crossed by many fine lines'' which are all said to be 
brown, the ground-colour of the hindwing also brown rather than light grey. 
C. aemyla sp. n. (18 f). An interesting addition to section A of Xanthorhoe, quite unlike anything pre¬ 
viously known to me. Palpus about 2; pectinations moderate (tips of antenna lost). Abdomen relatively slender, 
uncus curved, much as in ferrugata, costal cliit-inization of valve very strong, sacculus also chitinized proximally, 
calcar apparently short (examined in situ). Forewing rather broad, its pattern and colour-scheme much as in 
0. chenopodiata, hut with a lighter, less brown ground-colour. Hindwing somewhat produced near apex, 2nd 
radial from the middle of the discocellulars, thus appreciably behind the cell-fold (slightly transitional towards 
Larentia and Colostygia) ; white, almost unmarked excepting the thick, slightly interrupted terminal line. Fore¬ 
wing beneath greyish, weakly marked, a pale line separating the somewhat darkened median area from the 
distal. E Tibet: Posho, 16 000 feet, 20 July 1936 (R. J. LI. Katjlback), a good q in the British Museum. 
p. 128. to C. desiynata. ab. coarctata Prout (13 b). We figure a very beautiful modification from a 
drawing kindly furnished by Mr. Chr. Lttmma. The specimen, a <j>, was taken by him at sugar on 28 August 
1935 at Cranz. In addition to unusual colouring, the weakening of the costal end of the band is noteworthy. 
p. 129. to C. obstipata. — ab. kuthyi Szent-Ivdny. Ground-colour rather brighter than usual, median 
band of forewing strongly interrupted (more so than in ab. interrupts) but much darkened, almost black: dark 
anterior subterminal shade also intensified. Kiskanhalas, Rest- County. 
p. 132. to C. aqueata. jurabia Wehrli nom. nov. (12 f and the English text as jurassica). Dr. Wehrli 
(in litt.. 1 December 1937) has acceded to my proposal (p. 140) that the name jurassica which he originally 
gave to this race should be regarded as preoccupied and has substituted jurabia. 
p. 133, to C. salicata Him. Amsel .regards the forms from Palestine as decidedly nearer to the name- 
form than to either of the other races. I have but very little material from the country (Haifa, Nazareth and 
Mount Carmel. February and March), but this agrees essentially with ablutaria as I known it from S. France 
(loc. typ.), Malta, Greece, Syria, etc. He, however, reports it common (predominantly $) at Kiriath Ana vim, 
ca. 500 m, 27 March and Tabgha. Lake of Genezareth. 30 March.

Faroe Islands has recently been analysed by this author and some forms named. Ab. koehni. with strongly
