decorata. is named decorata Krul. r rins is described from East Russia, but it probably occurs occasionally everywhere 
where the species is common. These spots can sometimes be conjoined with the outer band thus forming radial 
streaks. - Still more extreme specimens in which there are also wide silvery streaks on the hindwings at the 
strigosa. margin and in the interstices between the dark veins are called strigosa Hartw. — hectica 0. B.-H. (15 e) has 
golden stripes instead of the normal silvery ones. The inner stripe consists of 3 confluent spots. The outer 
one of separated spots of which 3 are at apex, then one obliquely inwards and somewhat low r er and then a 
laigei one at inner margin. 1 his form can also occur anywhere. I have a specimen from Sojmonowsk (in the 
l rals) m which the spots are distinctly yellow, but not quite as extreme as is the case in hectica hectica ema¬ 
nates from the neighbourhood of Irkutsk (Sajan).

outer band somewhat resembles that of fuscomaculosa de Geer (Vol. 2, pi. 54 d) in its shape, but it extends rather 
more vertically. The inner band is like that of macilentus (Vol. 2, p. 436, pi. 54 f) but it is more dismembered 
sordula. and the spot markings are coarser. 36-46 mm. Irkutsk (Sajan). — sordida Nordstr. from Kamschatka resembles 
i rct \ a Ca]a m the arr angement of its markings. Forewings pale brown with silvery white bands and spots 
Hindwings grey-brown with pale brown spots on costa. In one specimen among 3 at my disposal the white 
markings are heavily mottled with brown. 
H. nebulosus-armoricanus Oberth. In Vol. 2, p. 434 a doubt was thrown on the correctitude of the locality 
indicated for this form. As Bang-Haas has meanwhile received identical specimens from China, there seems 
scarcely any doubt left that the original indication of the origin was due to a mistake. The form is therefore 
certainly not european, the type will have come from Ta-tsien-lu, as it is well known that Oberthur received 
a lot of material from that quarter. 
5. Genus: Pliassus Wkr. 
Ph -bouvieri Oberth. Whilst regius Stgr. (Vol. 2, p. 438, pi. 54 b) has only a few golden yellow spots 
which are absent m roseus Oberth. although same is much more profusely coloured red, we have the opposite 
extreme m bouvieri. The ground colour corresponds approximately to that of Hep. sylvinus-laeta (Vol 2 
pi 54 d) on both wings. The arrangement of the markings scarcely differs from that of regius, only there are 
golden yellow spots distributed over the entire forewing. 55 mm. Ta-tsien-lu.
