Lepidoptera of the Altai Motmtains. 355 



140. CE. nanna. Men. (PL XIII, fig. 3^8?; fig. 4 ^ 

 ab. ?). (E. hulda, Stgr., Rom. Mem., vol. iii, p. 149, t. xvi, 

 8$; ffl^. nanna, Men. op. cit. vol. vi, p. 200. 



I found this very rare at about 6000 feet in a rocky 

 larch wood above Kuyuktaua in the Tchuja Valley on 

 July 22nd, when I took a fresh male and a somewhat 

 worn female. At the time I took them to be a var. 

 of noma. On comparing them carefully with typical 

 specimens of nanna from Pochrofka on the Upper Amur, 

 with Menetries' figure of ^ nanna, and with Staudinger's 

 figure of $ hulda, afterwards identified by him with nanna, 

 I think mine are the same. The sex-mark in this species 

 is sometimes very well marked, in others as Staudinger 

 truly says,* " Nur sehr schwach bei einigen Stucken fast gar 

 nicht erkennen," but the number of the ocelli (in all my 

 specimens five on the hind-wing), the form of the band 

 on the underside which does not form such a sharp point 

 inwards as in noma, and the much more mottled and less 

 distinct band below than in ttrda (though fig. 3 in this 

 respect is aberrant), seem to me to make the species dis- 

 tinguishable from any other. I have a single specimen, 

 however (fig. 4), which I took at about 6000 feet near 

 Darkoti, in the same locality where sculda. was common, 

 and which I doubtfully assign to 7ianna. by its sex-mark 

 and the form of its clasp, in both of which it differs from 

 sculda ; but for the clasp, I should rather have supposed 

 this specimen to be an alpine form of noma. Though I 

 saw no noma in this district above the limit of forest there 

 was a clump of stunted larch in the neighbourhood where 

 noma miwht occur. Since writing the above I have 

 seen Dr. Staudinger's types of htUda = 7ianna, and am 

 convinced that it is a good species, and that mine are the 

 same. 



141. (E. sGulda, Ev. (PI. XIV, fig. 5 ^ 9 ? ; Plate 

 XIII, fig. 9 ? ab. $). 



This species and var. pujnila, Stgr., which has not previ- 

 ously been recorded from the Altai, but only from the 

 neighbourhood of Kiachta in East Mongolia, and from 

 Pochrofka on the Upper Amur, was first taken near Ongodai 

 on June 10th and was not uncommon on grassy hill-sides 

 in the Ongodai Valley ; though strange to say it was not 

 included in Mr. Jacobson's collection. lu the first half of
