120 THE CANADIAN ENTOMOLOGIST. 



in gre;U numbers, and in early May the adult was the common woods 

 mosquilo, a fierce and persistent biter within its dou)ain, from which it 

 did not venture. ^Veek after week these adults continued on, and not 

 until late July did they decrease materially in numbers. The last captures 

 were August i6, and as all the brood was out of the pools early in May, 

 these specimens had lived well over three months, and the bulk of the 

 brood had lived close to or quite three months. The possibility of a 

 second brood is absolutely excluded, because the local conditions were 

 kept under constant observation during the entire period. We begin to 

 hope that even in 1907 we may yet learn something new concerning these 

 interesting creatures. John B. Smith, New Brunswick, N. J. 



TO COLLECTORS OF NOCTUIDS. 

 Sir George Hampson is now working at the Acronyctinse for his "Cata- 

 logue of the Lepidoptera Phalenfe in the British Museum.'' He writes 

 that this group includes all the genera he has not yet dealt with in Dyar's 

 Catalogue down to page 197. He is very badly off for Canadian species, 

 especially from Eastern Canada, in the genera Apatela, Hadena, Papai- 

 pema, Caradrina, etc., and large series of as many species as possible will 

 just now be of great assistance to him. I therefore make an ap})eal to 

 Canadian entomologists to help in this great work, and will gladly receive 

 and forward free of all expense any specimens which Canadian collectors 

 may be willing to send either as donations to the British Museum or as a 

 loan for study. 1 shall be glad if those having duplicates for exchange in 

 this genus will correspond with me. The above Catalogue is of special 

 use to Lepidopterists of the whole world, and as we now know that 

 Canadian specimens will be acceptable, I have little doubt that many 

 Canadians will help in building up the collections in the British Museum, 

 which is a safe dej)Ository for insects, and where every facility for study is 

 given to students from all parts of the world. Good specimens of all 

 Noctuids, particularly from Eastern Canada, will also be acceptable, but 

 at the present time the .\cronyctini« arc most desired. Letters and 

 l)arcels of specimens can be sent to me free of postage if addressed officially.
