THE CANADIAN ENTOMOLOGIST. llo 



egg, larva, pupa, and imago, that the three Saturnias, spiniy pavonia and 

 pyri, differ in degree of specialization ; that they are phylogenetically of 

 different ages, spuii being the oldest, or least specialized, and pyri the 

 youngest form. The hybrid larvae between the first two and last two are 

 figured adjacent to the normal forms, and the greater resemblance of the 

 hybrid to the more generalized form in each case is striking, thus neatly 

 confirming the conclusions already reached, and all on the lines laid 

 down by Weismann. 



Our author also gives an account of experiments on the effects of 

 different temperatures on hibernating larvae and pupse, with figures of 

 some of the forms of imago produced. There is an account of varia- 

 tion, seasonal dimorphism, local forms, etc., discussed from the most 

 recent scientific standpoint. The book contains much of interest which 

 it is unfortunate that we are not able to enjoy more easily in an English 

 edition. Harrison G. Dvar. 



British Moths, by J. W. Tutt. London : George Routledge & Sons- 

 Pp- .^65. 



The young collector in the British Isles will no doubt welcome this 

 manual, which will not only help him to name any specimen that he may 

 collect, but give him also much information regarding the habits of the 

 moth in its preparatory as well as perfect stages. It is written in the 

 author's well-known pleasant and readable style, and is not merely a dry 

 handbook. There are twelve coloured plates and over sixty wood-cuts, 

 illustrating the majority of the families. There are also a number of 

 tables, giving the times of year when the species may be looked for in the 

 egg, larval, pupal, and perfect states ; the food-plant of the larva ; the 

 location of the pupa; and notes on the variety or abundance of the moth. 

 It would have added much, we think, to the handiness of the book if it 

 had contained comparative tables of genera and species as well. 



Random Recollections of Woodland, Fen, and Hill, by J. W. Tutt., 

 F. E. S. London: George Gill & Sons. Pp. 256. [2s. 6d.] 

 We are glad to see that a second edition of this delightful litile book 

 on outdoor natural history has been called for. In this new issue the 

 matter has been, to some extent, rearranged and revised, and its attrac- 

 tiveness has been much enhanced by a pretty cover and over a hundred 

 excellent illustrations. Though it deals with " Old Country " scenes, 

 and the insects, birds, and plants that frequent them, it can be read with 

 great interest by any lover of nature in any part of the world.
