PERICARDIA. By Dr. M. Dbatjdt. 
sub - H. subftebulosa Dyar (Vol. 6, p. 325, pi. 42 b). This small species, which was first found in Alaska and 
mbidobu. which closely resembles festiva, differing by its ochreous grey hindwings and the reduced size of spots of fore- 
wings, has now also been discovered in northern Siberia at the mouth of the Jenisei. The only known from 
there has somewhat more extensive yellow spot marking than the $ type, the spots in the centre of costa 
are confluent, abdomen reddish brown, underside and tuft of abdomen orange red. 
H. alpina Quens. (Vol. 2, p. 95, pi. 17 e). We are illustrating again (7 d) this beautiful species from 
a perfect specimen from Sajan, which has been very kindly placed at our disposal by Mr. 0. Bahg-Haas. 
The species is so variable that scarcely any two specimens are alike, the hindwings occur in all shades of red 
sibirica. to yellow. — sibirica 0. B.-H. from the Altai is more daintily built, the wings somewhat narrower and elongated. 
johanseni. colouration of hindwings pale rose. — johanseni 0. B.-H. is the form from arctic America from C'ollison Point 
(North Alaska). It must be mentioned here and it is interesting to find its occurrence in circumpolar regions, 
just as is the case in subnebulosa. It is most similar to sibirica, spots of forewings creamy yellow, basal black 
of hindwings reduced to 2 streaks. 
H. seitzi A. B.-H. (Vol. 2, p. 95, pi. 56 g). As synonyms must be mentioned: strandi Niepelt and niepel- 
Jchumbeli. liana Strd. — khumbeli 0. B.-H. differs from the name type by the dull yellow colouration of the spots of 
forewings, which are confluent, forming bands, hindwings with duller red colouration. Prom the northern 
Central Thian Shan (Alma Ata) at 3080 m. altitude, captured at end of July. 
soidiei. H. souliei Oberth. placed by Hampson in his group of Genus Arctia in juxtaposition to alpina. Head 
led, neck yellow, thorax black with yellowish red streaks, abdomen red with black spots. Pore wings dark 
brown with 6 yellowish red costal spots, a curved stripe from base of innermargin to the centre of the sub- 
median fold and an oblique irregular postmedian band between 3 and the inner margin; an oblique band ex¬ 
tends from 4 to the margin along submedian nervure and between veins 6 and 4 there is a subterminal spot 
with 2 sharp points. Hindwings red with black streak on submedian nervure, minute spots in centre and at 
end of cell and a subterminal band of spots. In the $ the markings of forewings are more extensive and more 
contiguous, hindwings a purer orange. W. China (Ta-tsien-lu). 
H. aulica L. (Vol. 2, p. 95, pi. 17 e, f). We are illustrating the forms liamata and radiata (7 d) men- 
rishiriensis. tioned in the main Volume. — rishiriensis Mats, has much larger yellow spots, the one at anal angle resembling 
that of testudinaria, the spot behind the cell, as large as the one at end of cell, a small yellow spot between 
same and the anal spot; hindwings with smaller basal spot, which is separate from the longitudinal streak 
at inner margin. Wing expanse 34—40 mm. Hokkaido. 
j lave °- H - testudinaria Fourcr. (Vol. 2, p. 96, pi. 17 f). — flaveofulgens DU. is a form from the S. Tyrol in 
periUjpa. t ^ le r ' ( '^ brown of the forewings is changed to a pale reddish yellow. — perilypa Schaw. on the other 
hand has very dark brown forewings with reduced yellow markings; hindwings with wide black continuous, 
not interrupted, marginal band, the basal 3rd quite black, with bold black central spot; described from Terlan. 
fasciaia. fasciata Dlil. are similar, but forewings of normal colouration, only a small dentate band of red is left on 
eonfluens. hindwings. confluens DU. has the long inner marginal spot extended stretching widely over the surface of 
pauci- the wings. paucimacula Dhl. is the extreme opposite with remnants of the dentate outermarginal spot and

pletely dark brown or with a circular yellow spot at base; hindwings extensively spotted with black. — jla- 
vescens Oberth. is synonymous with crocea Schultz.

P. matronula L. (Vol. 2, p. 9G, pi. 17 f, g). To the many forms described by Schultz, we have to add 
^luteotineta ^bowing; niarmorata Schultz with heavily enlarged spots on forewings. — luteotincta Schultz with orange 
obi iter at a. H'bowish ground colour of forewings. — obllterata Shelj. is an interesting aberration with yellow Brewings, 
irregularly suffused with brownish; the orange-yellow hindwings entirely or almost devoid of spots, similarly 
amm-ensis. the upperside of abdomen; 2 such specimens bred in S. Russia (Province Kostroma). — amurensis Shelj. is 
much smaller than european specimens, of paler brown almost yellowish colouration, the yellow spots larger, 
a fairly large spot also on the inner margin. Hindwings paler orange yellow with smaller black spots. 
Nikolajewsk. In contrast to the form just described, specimens from the southern Amur territory, Ussuri 
sachet- and eastern Mandchuria do not differ from european specimens. — sachalinensis form. n. (7 e) is similar to 
the preceding form, but larger and more slender in build; thorax similarly pale brown as the ground colour 
of forewings and not such a deep black as in specimens from Germany, the spots as deep an orange as the 
hindwings, scarcely larger than in type and always, also in the with an anal spot, spots of hindwings small 
and narrow, abdomen with a row of spots. Very common on Saghalin. 
mnssoti. P. mussoti Oberth. classified by Hampson in this Genus with a query. Head and thorax brown, the 
latter with white stripes, abdomen brown with carmine red bands dorsally, red laterally and white transverse 
bands ventrically. Forewings brown with yellow white triangular spot below' base of cell, some small oblique
