Hugh Main and Mr. A. E. Tonge, who have attained a very high 

 excellence in this fascinating art. In conclusion we can only say that 

 Mr. Tutt deserves the heaviest thanks, alike of student and collector, 

 for his magnificent work, and thoroughly deserves the support of 

 everyone who can possibly afford to secure a copy. The purchaser 

 will never repent of his investment. — G. II. R.

The Rev. C. R. N. Burrows, The Vicarage, Mucking, Stanford-le- 

 Hope, Essex, would be thankful for eggs, larvas, and pupas of Geometra 

 rmiaria, Aplasia ononaria, and Thalera Umbrialis, to complete his life- 

 histories of our " emeralds." Probably some of the Geneva entomo- 

 logists will get the latter. It occurs at Chavoire, on Lake Annecy, at 

 Bourg St. Maurice, and possibly all over the Savoy country. 



After much delay, the fifth volume of The Natural Histori/ of 

 British Lepidoptera has been published. It consists, as usual, of two 

 parts, the first containing two long and detailed chapters on " Hybridisa- 

 tion of Lepidoptera" and " Mongrelisation of Lepidoptera" (with, at the 

 end, a considerable appendix to these chapters), the second containing a 

 full and very complete account of the species on the Agdistid and Pla- 

 typtiliid side of the " plume" stirps. The chapters on " Hybridity " 

 and " Mongrelisation," containing as they do full details of all the 

 experimental material available that has been published, together with 

 a critical discussion of the general principles underlying the pheno- 

 mena, and the results obtained, will attract attention from a large class 

 of lepidopterists engaged in this side of our fascinating pursuit, whilst 

 the account of the " Plumes" can be safely said to outrival, in its com- 

 pleteness, that of any group of lepidoptera yet treated of by any author. 

 The life-history of practically every species here dealt with, is now well 

 known, and has been, by the author and his collaborators, worked out in 

 such detail that nothing much can be left untouched. The publication 

 of the remaining species now becomes a positive necessity, and it would 

 be little short of a calamity that rather more than one half of the British 

 species of " Plumes " should be so amply dealt with, whilst the biology 

 of the others is, in the light of the new work, absolutely unknown. To 

 lovers of "lepidoptera," and "plumes" in particular, the volume will, 

 no doubt, prove a most welcome addition to the library, and will be a 

 continual companion in matters of difficulty. 



Parts 1, 2 and 3 of vol. ii. of A Natural History of the British 

 Butterflies, their world-wide Variation <<n<l Geographical Distribution, 

 are now completed, and ready to be sent to subscribers. They contain 

 complete chapters on "The hybernation of butterfly larva" and 

 "The gregarious habits of butterfly larvae," together with an account 

 of the " Ruralidae or Hairstreaks," the subfamily Ruralinae, the 

 tribe Ruralidi, the genus " Gallophrys,'" and a thorough detailed 

 life-history of Callophrys rubi, dealing with both the systematic 

 and biological sides under the following headings: "Synonymy," 

 "Original description," "Imago," "Sexual Dimorphism," "Varia- 

 tion " (with original description and full accounts of all known races 

 and aberrations). "Pathological examples," "The Green Coloration 

 of the underside," " Egglaying," "The Ovum," "Larval habits," 

 " Larva," " Parasites," " Pupation," " Foodplants," " Pupa," " Pupal
