and occasional examples of fingal occur in the Alps (I 

 have one from Tarasp). 



A. imjrina, though a very near ally of selene, next to 

 which, perhaps, it should be placed, is sufficiently 

 distinct and constant to be recognised. It seems to 

 have a very wide range in the colder but not in the 

 arctic parts of North America, but is somewhat local. 



A. altissima, gemmata, and clara are three allied, but 

 very distinct and beautiful species, which seem best 

 placed here ; they are all confined to the alpine regions 

 of the Himalaya. The exact habitat of A. clam was 

 long doubtful, but it has lately been found by Mr. Duthie 

 and others at Gangootri, near the source of the Ganges, 

 and at Phuladaru, in the province of Gurwhal. A. 

 geiiimata occurs somewhere in the same country, as well 

 as in alpine Sikkim, where it seems very abundant. 



A.jerdoni and A. gong are also allied species, though 

 easily distinguished from each other by the markings of 

 their under side. One inhabits the western, the other 

 the extreme eastern edge of the great Asiatic highlands, 

 and both as yet are known from one locality only, though 

 their range is probably not so restricted as it seems. 



A. pales. — The varieties of this species are so endless 

 that it seems almost impossible to retain names for any 

 of them except the form known as arsilacJie, which 

 occurs in the peat-bogs of Northern Germany, and in 

 Northern Europe and Asia ; and which by some good 

 entomologists, among whom Zeller and Meyer-Dur are 

 prominent, is considered as a distinct species. After 

 studying very carefully and repeatedly my own collection, 

 containing 74 males and 56 females, in which all the 

 known forms except the Greek one are very fully repre- 

 sented, and seeing thousands of specimens in other 

 collections, I do not see how any of the named forms can 

 be defined with certainty, and though typical specimens 

 from the Caucasus and Central Asia could be recognised 

 as local variations, they are nowhere constant to one 

 type. The most distinct are those from some parts of 

 Central Asia (var. generator, Stgr.), especially from 

 South-western Altai, and the Skorolah in Western Ladak, 

 some of which have the spots on the upper surface 

 almost obsolete, and the under side very peculiar. 

 Those from the Caucasus (var. caacasica, Stgr.) are 

 very bright in colour above, and much spotted below,
