42 THE CANADIAN ENTOMOLOGIST. 



in the middle of May ; does the larva hibernate ?" He also says, '* it is very 

 rare in Mass" (1863). I with many others had been in anxious search for 

 this beautiful butterfly up to 1866 without success, except in the extreme 

 southern part of the State, now all of a sudden in this year (1866) they were 

 found in their special localities, low and swampy meadows, quite plentiful, 

 and have continued still more plentiful (from June 17 to July 8) to the 

 present time. Dr. Harris collected in this vicinity from about 1825, and 

 with a few exceptions never had met with it. 



It is possible that in some instances they may be double brooded, but I 

 have never met with it out of its special season. — Philip S. Sprague, 141 

 Broadway, South Boston, Mass. 



Occurence op Deilephila lineata in England. — In the September 



and October numbers of the Entomologists' 3IontMy Magasine (London, 



Eng.) there are numerous accounts of the capture of this handsome sphinx 



in various parts of England. Is this the same species as that taken in this 



country, or is it the European D. livornica, the D. lineata of Fabrieius' 



later works, and of Stephens ?

EXCHANGES. 



CoLEOPTERA. — I am desirous of exchanging Coleoptera, as I am forming 

 a collection of North American Coleoptera, and wish to get every species 

 from every part of North America in which it may be found. If you can 

 put me in the way of any Canadian collectors who wish to exchange I should 

 be very much obliged. I have at present a collection of about 2,000 species, 

 mostly from New England, N. Y., Penn., D. C, and Mich., — very few 

 Northern or Western species, and am desirous of making arrangements to 

 get such. — E. P. Austin, Cambridge, Mass. 



Htmenoptera. — Mr. E. T. Cresson, of Philadelphia — whose valuable 

 paper, containing original, hitherto unpublished descriptions, of new Canadian 

 species of this order, we print on a previous page — begs to inform the Ento- 

 mologists of Canada that he will be glad to determine specimens of Canadian 

 Hymenoptera for any one who will send a duplicate set, duly numbered to 

 correspond with their cabinet specimens, to the care of Johnson Pettit, 

 Esq., Grimsby, Ont., who will forward them to him. He will describe all 

 the new species thus received in the Canadian Entomologist. There is a 

 peculiar fauna in this country of which he would like to get a good collection 

 so as to make the species known to science. 



We trust that all our Canadian readers will send on what undetermined 

 Hymenoptera they have, and make a point of collecting diligently in thig 

 interesting order next year. — Ed. C. E.
