148 THE CANADIAN ENTOMOLOGIST. 



a warm room and supplied with plenty of food, consisting chiefly of the 

 roots of growing wheat, earthworms, etc. As the female deposits her 

 eggs in early spring, they are probably nine or ten months old now. The 

 mature insect is an inch and a-half long, while these are but little more 

 than a third as long. Westwood says that vulgaris is inactive in winter. 

 These have been active at all times ; that is, not in any sense torpid, nor 

 were they when taken. 



When I first secured them I put them in a jar of earth, and gave them 

 no further attention for several days. In the meantime one disappeared, 

 and probably served to satiate the appetite of the rest, as they are known 

 to devour their own kind sometimes when they can obtain no other food. 



Since then, in exhibiting another before my class, it was accidentally 

 injured and died. I shall try to rear the remaining three to maturity, and 

 figure the various stages. I cannot say what stages they have already 

 passed through. The larvae of tnilgaris are white before the first moult. 

 These were dark velvety, and had moulted once or twice, I suppose. 

 They have not moulted since. 



I have written these notes in the hope of calling out other observations 

 upon the early stages of the insect. And I should be glad to know of any 

 one who has studied or figured the preparatory stages. 



FOURTH ANNUAL MEETING OF THE ASSOCIATION 

 OF ECONOMIC ENTOMOLOGISTS. 



In accordance with an action of the Association, taken at the Wash- 

 ington meeting, the Fourth Annual Meeting will be held at Rochester, 

 New York, two days prior to the meeting of the American Association 

 for the Advancement of Science. 



All members intending to present papers are requested to forward 

 titles to the undersigned before August ist., in order that the programme 

 may be prepared in proper season. 



The proceedings of our meetings are attracting the attention of working 

 entomologists of other countries, and it is to be hoped that members will 

 spare no efforts to make the coming meeting even better than those which 

 have preceded it. Owing to the continued ill-health of President Lintner, 

 and in order to relieve him of as much labour as possible, all correspond- 

 ence, unless of a nature necessitating his attention, may be addressed to 

 the Secretary. F. M. Webster,
