with dotata, though more weakly marked. In any case, to judge from the available material, it is not racial 
in Arctic Norway, hence the question has not much importance. — ab. binderi Marschner (11 e) has the yellow binderi. 
or ochreous ground-colour of the forewing replaced by dark brown, the hindwing also smoky, the dark markings 
in part obliterated, the pale lines which define the median band, as well as the apical streak, still present. At 
altitudes of 1100—1360 m in the Riesengebirge it is about as common as the type form. This is certainly the 
musauaria of our Vol. 4 (p. 212) and of common usage, but —- ab. musauaria Frr. (= musauria Frr.) (11 e), musauaria. 
of which the (unfortunately worn) type from the Musau Alps was described in full detail by Speyer (Stett. Ent. 
Zeit., Vol. 26, p. 256), is still more uniformly dark and should probably supplant fuscata Prout, though actually 
it is a rare (not quite unique) development in that the outward projection of the median band forms a single 
tooth; in true fuscata the band can no longer be traced at all. — ab. tatrica Pruffer, from the Polish Tatra, also latrica. 
sunk (by Romaniszyn) to musauaria, is uniform “ochreous-brown”, probably a synonym of rufescens rather 
than of musauraia. — ab. intermedia Schawerda is a frequent mountain form with strongly darkened median intermedia. 
band and (generally) terminal area, but with the yellowish ground-colour remaining at least in the subtriangular 
patch between the band and the apex. Described from Lower Austria. —- ab. mediofasciata Nitsche (11 h). Me- mediofascia- 
dian area uniformly darkened (“violet-brown”), but the darkening of the distal area faint. Altvater. An 
extreme of the same, with the forewing almost unmarked except for the strong basal and median bands, has 
been described and figured from the Linz district by Klimesch (Zeitschr. Oesterr. Ent.-Ver., Vol. 13, p. 3, pi. 1, 
fig. 7). We figure a small $ from the J. A. Clark collection. —- ab. inversa Nordstrom has the colours of the inversa. 
forewing reversed, so that the median and basal areas are yellow and the rest of the wing brown, with apical 
dash hardly visible; the light yellow hindwing has a broad brown distal border. The figure show r s that the 
dark suffusion along and in front of the median vein persists, dividing the yellow median area into unequal 
parts, and that the broad dark border of the hindwing is not absolutely solid. A $ from Enskede, near 
Stockholm. — ab. pallidata Lambill. “Median band very narrow, hardly dulled with brown.” The former pallidata. 
character, as Derenne points out, precludes my suggestion of sinking it to ab. lutea. It seems to be, Kli¬ 
mesch says, an ab. dotata with the median area constricted, a very rare manifestation, though known to 
him in ab. intermedia and ab. mediofasciata. The last-mentioned entomologist, who for a number of years has 
made a special study of populata, notes the Belgian race (?) as smaller than that of the North Tyrol, generally 
also with some further slight deviations. It is to be hoped that his promised monograph may yet see the 
light. — The wide distribution of the species will be better appreciated if I add Italy, Amur, Saghalien and 
Corea to the outline giyen in Vol. 4 (p. 212). 
L. peloponnesiaca Rbl. (11 c). Though so local, this fine species has now found its way into many col- peloponne- 
lections and we are able to give a figure of it. 
L. ledereri Brem. (Vol. 4, pi. 8 g) inurbana subsp. nov. (11 a). Very variable in size, but on an average ledereri. 
(especially in the 2) definitely larger than /. ledereri from the Ussuri district, ground-colour less whitish, the inurbana 
dark markings less ochreous, more suffused with grey, hindwing also as a rule more suffused, its cell-dot much 
oftener obsolete, in any case minute and generally weak. Japan, the type from Hakodate, in Tring Mus. 
L. tertrivia sp.n. (11a). In a measure intermediate between convergenata and ludovicaria (Vol. 4, tertrivia. 
pi. 8 d); whiter than the former, though not without some buff suffusion, the white band which crosses the 
cell of the forewing still more oblique and much narrower, tapering, the three lines composing the three groups 
which converge on the ample, suffused tornal area much more regular inter se than in most convergenata (our 
figure of the latter is exceptional), a line or shade developed between the subterminal and the termen. Tu- 
pa-keo, Szechuan, 7400 feet, 7 September (Kelley-Roosevelt Expedition, 1929), type $ in the Tring Museum, 
unfortunately torn and rubbed, but unmistakable. I do not think it will prove to be merely a local race of 
convergenata. 
L. pyropata Hbn. (Vol. 4, pi. 8 g) appeared suddenly in great abundance in East Prussia in 1915 and pyropata. 
1916 and Zollner has contributed (Iris, Vol. 30, p. 195—202; Vol. 33, p. 1—6) notes on its early stages and 
variation, besides a supplementary one (Vol. 33, p. 6—-8) comparing the pattern with that of the allies. Egg 
minutely granulated, micropylar rosette with 9—12 irregular rays. Larva up to the last moult very slender, 
with strikingly small head, mostly light-green; the characteristic pattern develops in the last stadium. It 
then tapers gradually to the head, excepting a protuberance on the mesothorax; variable in colour between 
green and brown, dorsal markings much as in prunata, etc. Feeds on Ribes nigrum and is, like most of the 
genus, easy to rear. Pupa strongly spindle-shaped, with produced cremaster, bearing on each side 3 short 
bristles and at the extremity “spirally curled” ones. Likewise variable in colour, following that of the larva. 
- ab. flavobasata Zollner has the basal area of the forewing light rust-yellow instead of the usual grey-brown, fiavobasata. 
— ab. subnigra Zollner is slightly (scarcely) darkened above, but has the underside strikingly melanic. — ab. subnigra. 
melanoxantha F. Wagn., founded on material from the same source, has the upperside also strongly suffused melanoxan- 
with dark grey, excelsa Sterzl ds Ecker, bred from a Konigsberg pupa, is virtually a synonym. —- sugitanil subsp. tfia - 
nov. (= pyropata Wileman, 1911) (11a). Eorewing with antemedian white line almost evenly curved, sub- 
sugitanii.
