often flies as early as the end of June in some localities. Only in 

 this way can I explain to mys^elf what he has written about his speci- 

 mens ; all his observations tend towards such an explanation. 



In fact, the three species, Mcera, Hiera, and MegcBrn, are in onr 

 country not at all difficnlt to distinguish from one another; they are 

 quite distinct and constant, and may be easil}^ separated. Besides I 

 will here call attention to the important discovery of Prof. Anrivillius 

 in Stockholm, that the male scales are quite different in them.* 



Also in Erehia Ligea and Euri/ale Prof. Anrivillius has found 

 quite characteristic differences in the male scales. f All onr Scandi- 

 navian specimens are decided Ligea, and there seems to be no reason 

 at hand to look at them as a transition to the Euryale of the High 

 Alps, from which they may be well distinguished. 



On the contrary, the Melitcea on Dovrefjeld is a complete con- 

 necting link between Afhalia, AureJia and Pnrthnnie, the si)ecifie 

 characters of which here run completely together, so that it seems 

 quite impossible to differentiate them one from another, however 

 distinct and constant they may possibly be in other countries. 



For Scandinavian Lepidopterists there is nothing new in Dr. 

 Jordan's list of his captures, except that Sesia scoliccformis was taken 

 in Romsdale ; that is a new locality for this species, though it has 

 been found even in Lapland. As for the other species, they have all 

 been found before both in the same and other localities. 



The British Entomologists who might be interested to see what 

 is known about the Lepidopterous fauna of either Dovrefjeld or 

 Eomsdale only, I will refer to the lists I have given in '' Xyt Magazin 

 for Naturvidenskaberne," Christiania, 1878 and 1881, showing for 

 Dovrefjeld 266 (now about 300), and for Romsdale only, 356 species of 

 Lepidoptera. It may perha])s be as well here on this occasion also to 

 mention that the whole number of Lepidoptera at present known in 

 Norway is about 1270 species. It will then be seen that our country 

 is not at all so poor, or such a terra incognita in this respect, as it 

 seems to have been thought by perhaps the majority of British 

 collectors.

P.S. — Since writing the above, I have received, through the kind- 

 ness of Mr. Gt. T. Baker, a coloured draAving of Dr. Jordan's supposetl 

 Bergen P. Hiera, which decides the question in the most decisive 

 manner. — W. M. S. : January lltJi, 1890.
