for my inspection; its hindwings, on both surfaces, have the band as 
narrow as on the upper side of forewings, where it is normal. Schoyen, 
in a survey of Arctic Norwegian lepidoptera (Arch. Math. o<j. Vicl., w, 
p. 198) mentions an example which is evidently referable here, and 
the Siberian form which I have recently received from Staudinger 
approaches it. Very similar again is var. Icadiakata Pack. ( Proc. 
Most. Soc., xvi., p. 23, pi. i., fig. 7,1874), from Kodiak I., Alaska, which 
unlike so many of the American forms—has the white bands on the 
upper side of all the wings, although (to judge from the figure) they 
are not very sharply defined nor very broad, so that the form stands 
between var. borsalis and the type, to which latter Dyar (Proc. V. S. 
Mas., xxvii., p. 895) doubtfully suggests sinking it. In the same 
place, Dyar correctly suggests sinking var. concordata to var. obductata; 
Gumppenberg (Nova Acta, iv., p. 279) has them separate, and by 
implication makes the former have no white band on the hindwings, 
even on the underside, but the type specimen shows that this is wrong. 
Ah. wcndlandti Fuchs (Jahrb. A ass. Ver. Nat. iii., p. 60, 1900) seems 
to come near borealis Peters., but is uncertain, Fuchs being so un¬ 
reliable in his determinations ; it is described from a single broad¬ 
winged example from St. Goarshausen. In direct antithesis to these 
dark forms, there is a var. albidior Alph. recorded from Kamtchatka 
(Bom. Mem., ix., p. 78, 1897) with more of the white than the type 
form. 
Put probably the “ hastata group” in its most restricted sense 
possesses the most interest for an audience of British Entomologists. 
This comprises five forms which have, at one time or another, been 
considered to rank as species ; hastata Linn., jothicata Gn., subhastata 
Nolck., thuleana H.-S., and hecate Butl. The last two are, by common 
consent, still treated as worthy of that claim, although Packard 
(Monogr., p. 165) is inclined to doubt it in the case of thuleana, whilst 
Dyar’s List of North American Lepidoptera, p. 278, sinks hecate as a 
synonym to hastata var. jothicata. Opinion is still somewhat divided 
on the exact strength of the claims of subhastata, but the weight of 
opinion (and, as it seems to me, of evidence) is against them ; while 
'jothicata is now universally sunk to hastata, notwithstanding a rather 
noteworthy peculiarity to which I shall refer presently. 
Rheumaptera hecate Butl. (Ann. Mar/. Nat. Hist. (5), i., p. 448, 
1878) from Japan is, so far as is yet known, a pretty constant species, 
although Leech (Ann. Mag. Nat. Hist. (6), xix., p. 570) mentions 
that his tw'o from Hakodate are smaller than any of Pryer’s extensive 
series from Oiwake, and have the central white band wider on the 
secondaries and towards the costa of primaries. The typical form is 
figured by Butler in 111. Tgp. Lep. Het., iii., p. 55, pi. iv., fig. 12 (1879). 
It bears considerable resemblance to the blackest form of R. hastata 
var. jothicata and to var. chinensis, but is quite distinguishable in its 
even more angulated central fascia of forewings, which is white 
•unspotted with black, and much broader in its costal than in its 
marginal half. 
Rheumaptera thulearia II.-S. (Sgst. Bearb., iii., p. 156, fig. 387, 
1848), only known from Iceland*, is a very interesting creature. It 
* Fuchs had a form from Krasnioarsk, Siberia, which he took to be this, but 
he tells us (Jahrb. Nass. Ver. Nat., liii., p. 62) that the determination was 
certainly incorrect.
