pyranthe, and notes on migration of butterflies in Ceylon (Trans. 
Ent. Soc., 1904, p. 701), also deals with the material of the 
Department, kindly presented by the author. 
Exhibitions of specimens belonging to the Department were 
made at the majority of the meetings of the Entomological 
Society of London throughout the year, accompanied by 
descriptive notes, which are published in the “ Proceedings.” 
The exhibitors and authors of notes were Dr. F. A. Dixey, 
Commander J... J.. Walker, Mr. G.cHe Verrall;y Drv tee 
Chapman, Col. J. W. Yerbury, Mr. G. J. Arrow, Mr. C. O. 
Waterhouse, Dr. G. B. Longstaff, and the Professor. 
The following short papers by workers in the Hope Depart- 
ment or upon its material have also appeared in the Proceed- 
ings of the same Society in the course of the year :—“ On the 
identity of the ‘ Bugong’ used as an article of food by the 
natives of Australia,” by Dr. F. A. Dixey; “A possible ex- 
planation of insect swarms on mountain-tops,” by the Professor; 
“The oviposition of Vanessa urticae,’ by Mr. A, H. Hamm ; 
“ The courtship of Vanessa urticae,”’ by the Professor ; “ Erebia 
evias, var. penalarae, and E. stygne, var. peralarae,” by Dr. 
T. A. Chapman; “ The scent of male Pierine butterflies,” by 
Dr. F. A. Dixey ; “ Pieris rapae seeking white flowers as a 
resting site,” by Mr. A. H. Hamm. 
Dr. G. B. Longstaff’s memoir, now in the press, has already 
been referred to on p. 26. 
In addition to the above list of papers and those published 
in last year's Report, there are two Presidential Addresses 
delivered to the Entomological Society of London by the 
Professor—in 1904, “What is a species?”; in 1905, “The 
bearing of the study of insects upon the question ‘Are acquired 
characters hereditary ?’.’ It will, therefore, be seen that the 
materials for the issue of a fifth volume of “ Hope Reports” 
are rapidly accumulating.
