Ze^idoptera of the Altai Mountains. 3S3 



mongolica by Stand iuger. What stood in Grum-Grshi- 

 mailo's collection as ichnea from Sutsclian, on the Man- 

 churian coast, is as large as typical maturna, and but little 

 different from it.

I found one variety of this, which is indistinguishable 

 from small European specimens, at Ongodai in the middle 

 of June, and another which most resembles meo'ope in the 

 high Tchuja Mountains the first week in July. I am 

 doubtful, however, whether the two forms keep distinct, 

 as one specimen taken in the dry Katuna Valley is of the 

 merope type ; underneath, however, they have the mark- 

 ings more distinct and not so confluent as in merope ; but 

 when a large drawer full of the numerous forms of a^crinia 

 from various parts of Europe and Asia are brought together, 

 it seems to me almost impossible to define many of the 

 numerous local varieties which have received names. The 

 form named sibirica, Stgr., which I have from Kentei and 

 Mongolia taken by Leder is, however, very much paler 

 than any of mine, as are those named var. mandschurica, 

 Stgr., from Sutschan taken by Dorries, 



91. 31. cinxia, L. 



Common in the Tchuja Valley, and as high up as 7000 

 feet in the mountains, where the specimens are very small 

 and dark. 



92. M. ardidnna, Esp. 



This is recorded by Lederer, and I have a specimen from 

 Grum-Grshimailo's collection from the Altai. 



{M. trivia, Schiff.) 



Recorded by Lederer but not seen by me. 



93. M. phoibe, Kn. 



I found ohis rare in the Altai. The specimens do not 

 differ sufficiently from European ones to require a varietal 

 name, though in East Asia the species becomes much 

 larger. Its local variations, however, are often very in- 

 constant. 



94. M. didyma, O., var. 



This was abundant in the Katuna, Tchuja and Bashkaus 

 Valleys, and also at Ongodai. The general average of my
