^Ging fasfuosclla, a name whicli had been given to the more purple 

 forma of the oak-feeding stihpurpurella, but now that Dr.^Wood has 

 enabled me to study a series of specimens bred from the hazel {Corylus 

 aveJIana), I can perceive that it is a distinct, yet very variable, species, 

 of which one of the most striking characters is that the anterior 

 wings are narrower than in any other of the group ; tmimaczolella'^h a 

 narrow-ranged species, but that has the anterior wings broader across 

 at the anal angle than Kaltenhacliii. 



Though years have elapsed since the death of Herr Kaltenbach 

 as this new species had to be named, I could conceive no name more 

 appropriate than that of the excellent observer who first bred the 

 insect, and thereby opened to us the interesting chapter of these larvsB 

 of the larger species of the genus Micropteryx. 



The larvse of the smaller species (calthella, &c.) are still, as men- 

 tioned by Dr. AV^ood (ante p. 6), a sealed book to us.

FDETHER NOTES ON DE. JORDAN'S OBSERVATIONS ON 

 NORWEGIAN LEPIDOPTERA. 



BY W. M. SCnOTEN, 

 Conservator at the Zoological Museum of the University of Christiana. 



Apparently Dr. Jordan finds it {ante vol. xxv, p. 362) still some- 

 what difficult to convince himself that it was Satyrus 8cincle jind 

 Mrelia Liyea which he did see at Bergen, and not, as he supposed, 

 Ghionohas Jutta and Erehia Blandina. I can, however, assure him 

 that nobody who is familiar with the habits of Jutta and with the 

 localities at Bergen, will think it possible that this regular moor 

 butterfly should fly on the rocks there in company with Semele ; and, 

 as far as the Erehia seen, there also can be no question at all about 

 any other species than Ligea, as Blandina is not known to occur in 

 Scandinavia. 



As for Vanessa urticcB, there is, of course, no distinct line to be 

 drawn between the ordinary form and the true var. polaris, as the 

 colour darkens quite gradually, owing to the climatical influences. I 

 will, therefore, not at all deny that both at Bergen and in other places 

 in Southern Norway there may be found, now and then, specimens 

 dark enough to pass for " pola)-is,'' but then as a mere accidental 

 aberration, not as a constant variety. As such a variety, urticce does 

 not occur at Bergen.
