212 [September, 



The First International Congress of Entomology was held in the grounds of 

 the Exhibition at Brussels, on August 1st — 6th, and was a great success, thanks 

 to the untiring energy of M. G. Severin, Dr. A. Lameere, Dr. Karl Jordan, 

 Dr. Walther Horn, and Dr. Malcolm Burr. A large number of well known 

 entomologists attended, or gave their siipport. Representatives from the 

 following coimtries were present : Austria, Belgivim, Egypt, France, Germany, 

 Great Britain (England, Scotland, and Ireland), Holland, Himgary, India, Italy, 

 Japan, Eussia, Spain, Sweden, tlie United States, Canada, Argentina, &c. Papers 

 on various subjects were read daily in the several sections, the Musee Royal 

 d' Histoire Naturelle de Belgique and the fine Congo Mtiseiun at Tc^rvueren were 

 visited, and between times there were always the attractions of the Exhibition 

 (free tickets for which were presented to the members of the Congress) avail- 

 able to those who wanted a change. But above all, it was a pleasure for many 

 of those present to meet some of their old or life-long correspondents for the 

 first time, and this alone, to many of them, was worth the journey. Great 

 Britain was particularly well represented, and the following papers, amongst 

 others, were read by our owti countrymen : Mr. G. Theobald, " Artificial distri- 

 bution of Insect Pests," and " The distribution of the Yellow Fever Mosquito 

 {Stegomyia fasciata) ; " Mr. J. M. Hewlett, " Economical questions in Bengal " 

 and " Preservation of collections in Tropical Climates ; " Mr. R. MacDougall, 

 " Galerucella lineola, its life-history and habits, with notes on preventive and 

 remedial researches ; " Sir D. Morris, " The disinfection of imported seeds of 

 plants and the iise of insecticides ; " Mr. G. H. Carpenter, " Notes on the 

 (Estridm ;" Mr. R. C. Punnett, " Mendelism and Lejndoptera-," Dr. F. A. Dixey, 

 " Mimicry ; " Mr. F. Merrifield, " Experimental Entomology ; " Professor E. B. 

 Potdton, " C. A. Wiggins's resea,rches on Mimicry in the forest butterflies of 

 Uganda, 1909-1910 ; " Mr. H. Donisthorpe, " Ants and their guests." Dr. Karl 

 Jordan also read a paper entitled "The Systematics of certain Lepidoptera 

 which resemble each other, and their bearing on general questions of evolu- 

 tion ; " and amongst the contributions of our Continental confreres, that by 

 Herr A. Handlirsch, entitled " Rekonstruktionen fossiler Insekten " (illustrated 

 by a large ntunber of excellent lantern slides), was of special interest. These 

 papers, and the fidl report of the Congress, will be published in due course, 

 there being, we believe, no lack of financial support. On the invitation of 

 Prof. Povdton, it was decided to hold the next meeting at Oxford in two years' 

 time (in 1912), to avoid any possible clashing with the triennial gathering of 

 the Zoological Congress in 1913 (their meeting for the present year, at Gratz, 

 immediately folk)wing the Entomological Congress at Brussels), and after that 

 triennially. 



The food-plant of Ceuthorrhynchus atomus. Boh. (== setosus, Boh.) — Whilst 

 sweeping for Coleoptera on a dry bank on Juno 10th last, I found a pair of 

 Ceuthorrhynchus atomus, Boh. (= setostis. Boh.), in the net, with a pair of the 

 common C. contractus, Marsh., and one Ceuthorrhynchidius floralis, Pk. After 

 reaching home and verifying my captures, I considered the whole of the flora 

 of this particular bank in hopes of solving the mystery of the food-plant of
