240 THE CANADIAN ENTOMOLOGIST. 



Insects in Winter. Not that these are more noteworthy than the rest, but 

 they will serve to give an indication of the contents of the work. 



Dr. Weed's "Stories of Insect Life" have been much appreciated, 

 and we are sure that his "Nature Biographies" will be still more 

 enjoyed, and will lead many, old as well as young, to observe for 

 themselves some of the wonders of the insect world — some of the marvels 

 that every day surround us. C. J. S. B. 



Mr. P. Wytsman (10S Boulevard du Nord, Brussels, Belgium) has 

 issued the prospectus of a proposed elaborate and important work, viz., 

 " Genera Insectorum " of the world. It is to be issued, provided one 

 hundred subscribers can be secured, in quarto parts, each containing 

 about 72 pages of text, and 7 plain or coloured plates. The price of each 

 part will be five dollars, and it is expected that 75 parts will be required 

 to complete the work. It is hoped that well-endowed libraries, both in 

 Europe and America, will render the publication practicable ; it is far 

 beyond the means of all but very few individuals. 



American Association for the Advancement of Science. — The 

 annual meeting will be held at Denver, Colorado, August 24th to 31st, 

 where it is expected that there will be a large attendance of members 

 from all parts of the continent. 



The thirteenth annual meeting of the Association of Economic 

 Entomologists will be held at the same place, beginning at 10 a.m. on 

 Friday, August 23rd. 



The editor desires to thank some unknown correspondents for send- 

 ing him (1) a pair of Attacics promethea and cocoon, and (2) a specimen 

 of the rare Sphinx moth, Triptogon modesta. He would remind corre- 

 spondents that it is in all cases desirable to place upon the outside of a 

 package the name and address of the sender, as postmarks are frequently 

 illegible, and it is not always possible to identify handwriting. 



Locusts in France. — An English newspaper correspondent relates 

 that these pests have been damaging vines, clover and oats in several 

 departments. Owing to the invasion of the locusts, the Government has 

 directed a committee of scientific agriculturists to meet at Aries for the 

 purpose of concerting measures to keep off the plague from the infested 

 districts. The place which has most suffered is the marshy and unhealthy 

 district in the Bouches-du-Rhone, known as the Camargue. 



Mailed August 3rd, 1901.
