Genus Golias. 145 



As regards the correct name of the form, I adopt 

 Felder's, because it is the most scientific, and because the 

 part of the P. Z. S. in which C. shipkee Avas described, 

 though read in June, woukl not have been published till the 

 end, or near the end, of the year, and therefore probably 

 be later than Felder's description, the date of publication 

 of which seems not quite certain. 



This is an essentially alpine form occurring at eleva- 

 tions of 14,000 feet and upwards in the dry region of 

 Ladak. 



C. melinos Eversm,, from the Amur region, is perhaps 

 another form of Phicomone, but is very imperfectly known 

 as yet, and maybe a distinct species. 



The vailous forms of Nastes are puzzling, and if I am 

 right in referring Kohandica Ersch and Behrii Edw., to this 

 species, the distribution is still more so. I am somewhat 

 doubtful about the last of these forms, which Mr. Strecker 

 considers distinct. I fail to see any good character by 

 which Nastes can be distinguished from Phicomone, of which 

 it may be only an arctic form. The var. Werdandi from 

 Lapland is just as likely to belong to one as the other, 

 though Phicomone as found in the Alps of Central Europe 

 does not seem to have so much tendency to variation as 

 most of the species.

I adopt Boisduval's name instead of the name Anthyale 

 Hubn., which is given to it by Staudinger, because the 

 latter expressly states in his account of that species that it 

 comes from Pennsylvania, which in my opinion proves his 

 Anthyale to be a small specimen of Philodice, God., Cf. 

 Mosch. Stett. Ent. Zeit., 1870, p. 113. 



This supposed species, which comes very close to Paloino 

 on the one hand and to Philodice on the other, is found in 

 Labrador, British Columbia and Colorado ; but various 

 forms of it which have been described as distinct species 

 under the names of
