224 THE CANADIA.N ENTOMOLOGIST. 



1883. Grt., Papilio 3, 113, takes euphrasice as type, and refers the North 



American sperata as belonging here. 



The genus, as proposed by Hubner, has mixed contents, and it seems 

 quite certain that aceris is not structurally identical with euphrasice. 



Two names proposed by myself: ineroloiiche with the type spinea, and 

 Eulonche with the type obiifiiia, may be assumed, with but little doubt, 

 as being of generic importance. There remain to be considered Meg- 

 acro7Hcta with the type americatia, probably distinct structurally from either 

 aceris or leporina; Lepitoreuma with the type ovata, and Mastipkanes 

 with the type xyli?ii/ormis. None of these groups seem to be repre- 

 sented in Europe, so far as my studies of the European species allow me 

 to judge at present. The larval forms of these subgeneric types will 

 throw some light on the phylogeny of the group, but are perhaps chiefly 

 interesting as illustrating the range of character shown by the independent 

 larval stage. 



BOOK NOTICES. 



Rambles in Alpine Valleys, by J. W. Tutt, F.E.S. ; 208 pages, 5 

 plates. London : Swan, Sonnenschien & Co. (Price, 3s. 6d.) 

 The editor of the " Entomologist's Record and Journal of Varia- 

 tion " has added another to his popular books on the beauties of Nature. 

 Tills time he takes the reader abroad to the lovely scenery of Switzerland 

 on the Italian slopes of Mont Blanc, where he wanders for the most part 

 out of the beaten track of the ordinary tourist. Much of the volume is 

 filled with charming pen-pictures of the infinite variety of grandeiir and 

 beauty to be found among the lofty mountain tops, the towering crags, 

 the densely-wooded ravines and the dashing torrents of this secluded 

 Alpine region. The eye of the naturalist does not fail to observe the 

 marvellous variety of animal and vegetable life that is to be found in 

 this limited area, and the author describes many a plant and flower and 

 especially the gay butterflies and pretty moths with which the region 

 abounds. Some of the most interesting passages are those that deal 

 with the phenomena of variation caused by environment, the results of 

 the glacial epoch in the distribution of species, the effect of altitude on 

 plants and insects, the evolution of the genus Colias, the production of 

 colours, the causes of hibernation, and other topics which arise from time 

 to time as the author rambles through the valleys or climbs the Alpine 

 hills. The perusal of such a book as this must help the reader to see 

 and observe, and lead him on to think out for himself the causes and the 

 objects of the life that everywhere surrounds him,
