indicates it as the most westerly locality vet known for the species. But as it has been reported from Russian 
Karelia further extensions of its area of distribution may be expected. 
p. 82. to B. tibiale Esp. My suspicion that the rough three-fold division into the races tibiale, moer- tibiale. 
oraria and eversmannaria, adopted by Staudinger. Cuxot and myself, was inadequate has already received 
some valuable support. An important article by Lankiala published in October 1937, gives a full survey of 
“The Baptria tibiale- races of Finland'' and I hope that those lepidoptirists who have sufficient material from 
other countries will follow it up on similar lines. Esper's type, with moderate white band and small tornal 
spot on the forewing, came from Winiky, near Lemberg (Lvov), where it was taken in August. moeroraria moeroraria. 
Frr. (Vol. 4, pi. 6 c) is the only known form in which the band is not approximately leg-and-boot-shaped but 
(as its author says) “splinter-shaped". eversmannaria H.-Sch. Lankiala correctly points out that this did eversman- 
not originally depict one of the b r o a d 1 y white-banded forms such as were figured by Culot from the Alpes 
Vaudoises and by me (8 d) from Hakodate, but more approaching what I had called ab. decisata Walk. The 
type (for which no locality was given, though the dedication to Eversmann suggests a clue) has the band of 
the forewing about 2 mm wide, its proximal edge directed* towards the tornus, but changing its course behind 
the 3rd radial so as to run hindward and form the “toe'", of the boot near the hindmargin; that of the hind¬ 
wing very narrow, reaching neither margin, anteriorly and posteriorly strigiform, in the middle broadening 
very little (maximum width 1 mm). Specimens from Irkutsk agree exactly with it. — fennica Lankiala has fennica. 
the band of the forewing as broad as in t. tibiale or even broader, the “toe” touching the hindmargin; that of 
the hindwing complete, quite strikingly broad, in the middle often reaching 3 mm but at both ends narrowing, 
especially behind. Hindwing beneath with 3 blue-whitish rays from the base, in part approaching or almost 
reaching the white band. S. and Central Finland, feeding on Actaea spicata. Some of the N. Asiatic forms 
are very similar. kauckii Schille (see p. 82) is also very like fennica , except in its much larger size (forewing A auckii. 
17 mm), but the band of the forewing does not reach the hindmargin (underside not described). The dates 
were early, 11 and 13 June. borealis Lankiala, from N. Finland, near the Arctic Circle, is on an average borealis. 
smaller than fennica ; narrower-winged, its shape distinguishable also from that of eversmannaria, its bands 
intermediate in width between those two races; underside of both wings with less of the blue-whitish sheen. 
Apparently attached exclusively to Actaea erythrocarpa, which the Finnish botanists treat as a separate 
species. It is suggested that fennica reached Finland from the south, borealis from the east. — ab. reducta reducta. 
Lankiala is an occasional modification of borealis with the band of the hindwing above reduced to a short 
central streak, often in addition considerably narrowed. decisata Walk. (18 k) resembles ab. reducta, but decisata. 
the band of the forewing is a trifle less oblique, its costal end more distally placed, its outer angle blunted; 
band of hindwing even slenderer than in reducta. A very closely similar pair (coll. Bellier), likewise without 
locality, suggests that it is European. Notwithstanding Walker s somewhat misleading description, albofalcata 
Schaiverda is almost the same form, though the band of the forewing is in this latter a little more shapely, the 
short white mark of the hindwing perhaps more bent. aterrima Btlr. (not atterima!) is not a mere aberration aterrima. 
but, I suspect, a mountain form in Japan. Large (36—41 mm), the band fluctuating between 1 and 2 mm, for 
the most part nearer the former measurement, its “foot" narrow, its slender toe ending at the 2nd median or. 
if extended behind, extremely narrow and weak; hindwing beneath with a slightly interrupted white line 
(rather than b a n d) running from the 2nd or 3rd radial to the abdominal margin. The type <$, sent from 
Yokohama, long remained unmatched, but all Wileman's tibiale from Yamato (Odai San. 1 8 July; Omine 
San, 4 2 19—20 July) agree perfectly with it. Elsewhere, the forms from Yezo, approaching evers¬ 
mannaria (8 d, as eversmannaria ). and those from Hondo, approaching tibiale and mychioleuca, require further 
study. mychioleuca subsp. nov., mentioned but not named on p. 82. has the band of the forewing broader mychioleuca 
than in our figure of tibiale (Vol. 4, pi. 6 c), generally 3 mm or almost, the “toe of the boot" short or moderate, 
the “heel” almost or quite as pronounced as in fennica. Best characterized by the white of the hindwing 
beneath, which is concentrated in a conspicuous spot at the abdominal margin, its continuation forward weak, 
evanescent or wanting. “Amur”, for the most part badly localized; Ussuri, the type in the British Museum 
from Egerscheid (Vladivostok); also Okeanskaja, Chabarovsk, etc. The E. Asiatic “ tibiale ” of Graeser and 
Staudinger will certainly belong here. — ab. nigrescens nov.. described by the latter from Sutschan. has even nigrescens. 
the band of the forewing obsolescent, only distinguishable by its weaker (grey-) black tone. 
p. 83, to Lithosteye. The careful work of Amsel on the western group of this genus, already referred 
to on p. 84, has stimulated further investigations into them, which have yielded unexpected and important 
results. Further, the chance discovery of an original of porcataria Bsd. and the consequent correction of an
