192 THE ENTOMOLOGIST S RECORD. 



figures of the different species. Students of the Diurni of the New 

 World will find two items which will specially appeal to them. One 

 is an abstract of a paper on " Mimicry in the North American Butter- 

 flies of the Genus Limenith," read before the Society by Professor E. 

 B. Poulton, in which he shows that the North American Danaina 

 serve as models for the species of the Nymphaline genus Lhnenitis, 

 or as its Nearctic forms are called Banlarchia. The other 

 paper is by Mr. W. J. Kaye, and deals with " The Ithoiniinae.'' There 

 are few living entomologists, certainly none in this country, who 

 can speak with greater authority, or have a more intimate knowledge 

 of, this rather obscure sub-family than the author of this paper. 

 Whatever he writes on the subject is therefore worth reading, and 

 those of us who have devoted some attention to these most interesting 

 butterflies are grateful to Mr. Kaye for his very helpful notes. The 

 Presidential Address is in the main a continuance of 'that of the 

 previous year, when Mr. A. E. Tonge, F.E.S., dealt at some length 

 with the problems connected with the first stage of insect life, the ovum. 

 This year he elaborates his subject by describing a large number of 

 British lepidopterous ova, Avhich had been "laid wild." Mr. Tonge has 

 made the study of the eggs of butterflies and moths particularly his 

 own, and in his address we have the result of a great deal of painstaking 

 observation, careful description, and accurate measurement. Nearly 

 one half of the volume is devoted to a record of the proceedings at the 

 fortnightly meetings of the Society, and we must congratulate the 

 Report Secretary on having induced so many of those who have 

 exhibited interesting objects in various branches of Natural History, 

 chiefly of course Entomology, to hand in for publication such full 

 notes' about them. A glance at this part of the work shows how 

 numerous and varied such exhibitions have been, and this, in itself, is 

 a healthy sign, and is full of promise for the future. — A.E.G. 



Heinrich Dohrn. {With portrait.) 



Dr. Heinrich Dohrn was born on April 16th, 1838, and died 

 unexpectedly at Florence, of influenza, on October 1st, 1913, in his 

 75th year. 



He was a member of a family of distinguished biologists. His 

 father was the well known entomologist. Prof. C. A. Dohrn ; his 

 brother Anton was founder and first director of the Naples Biological 

 Station, of which his nephew. Professor Reinh. Dohrn, is the present 

 director. Heinrich Dohrn was the chief organiser and director of the 

 Municipal Natural History Museum of Stettin, his native town, where 

 he was in recent years assisted by Dr. G. Enderlein. He was also the 

 tireless editor of the Stettiner Knto)i><il<);/ischen Zeitumf. He was the 

 author of a number of important works. His Versuch einer Mononraphie 

 der Derniapteren, published in the Stett. Ent. Zeit., 1863-67, was a fine 

 piece of work, in spite of the meagre material then at hand. It was 

 scarcely superseded even by de Borman's monograph in 1900, and is 

 to-day indispensable to the Dermapterist. 



Dr. H. Dohrn was a tireless worker, a member of the Imperial 

 Reichstag and a charming correspondent. — M.B.
