Monograph of the genus Hydrophilus (Coleop.) — M. A. d'Orchy- 

 tnont, Statiertzaat 58, Meenen, Belgium, is preparing a work on this 

 subject and desires to examine as many specimens of this genus as 

 possible. He would be glad to identify material for those who possess 

 it. He has published a paper on certain species of the Hydrophilidae 

 in tome XIX of the Memoires de la Societe Entomologique de Bel- 

 gtque, 191 1. 



The Lake Laboratory of the Ohio State University, at Cedar Point, 

 near Sandusky, Ohio, will offer courses of instruction in Zoology, 

 including Entomology, and Botany from June 17 to July 26, 1912, 

 while free tables will be open to investigators from June 20 to Sep- 

 tember 9. Further information may be obtained from Professor Her- 

 bert Osborn, Director, Ohio State University, Columbus, Ohio, or 

 after June 15 at the Lake Laboratory. 



The Memorial portrait of the late Dr. James Fletcher, Dominion 

 Entomologist, which is the work of Mr. Franklyn Brownell, R.C.A., 

 was unveiled at an evening meeting of the Ottawa Field-Naturalists' 

 Club on January 9th, 1912. It is an exceedingly good likeness and, as 

 most satisfactory arrangements have been made with the Municipal 

 Library Board and the Librarian of the Carnegie Library, the portrait 

 will be hung in a prominent place in this latter building. It will be 

 remembered that the Memorial Fountain, erected on the Central Ex- 

 perimental Farm, was unveiled on July 19th, 1910. The Fountain, in- 

 cluding the medallion, is the work of Dr. R. Tait McKenzie. of the 

 University of Pennsylvania, Philadelphia, U. S. A. 



Calpodes ethuus (Lepid.) — On November 5th, 1911, my friend, Mr. 

 Neuman of this city, discovered in his garden six caterpillars new to 

 him on Canna. As there was prospect of cold weather he took food 

 plant and larvae into the house so that they might not be injured by 

 the frost. Two days later they began to spin their cocoons which, 

 while not of a dense nature, were very strong, about twice the length 

 of the pupae. The color of the cocoon is white and has much the ap- 

 pearance of ordinary writing paper. The cocoon-spinning was done 

 in a way similar to that of Eudamus tityrus, beginning by pulling the 

 edges of the leaves close together. On November 20th, 21st and 22d, 

 the butterflies made their appearance and, much to the astonishment of 

 Mr. Neuman, proved to be Calpodes ethlius, a southern species. To 

 my knowledge this species has never been found feeding so far north. 

 Mr. Neuman has been so kind as to present to me a leaf containing 

 cocoon and chrysalis, also a fine specimen of the migrator's descendants. 



Frost occurred the night from Nov. 6th to 7th, which would have 

 proved fatal to the larvae. I conclude that, although the food plant is 

 plentiful here, the species could never thrive. — Ernest Schwarz, St. 

 Louis, Mo.
