THE CANADIAN ENTOMOLOGIST. 171 



mote its general health, or whether the diet of Colorado larvae was too 

 overpowering, I do not know ; but after eating about half a dozen larvae, 

 my bug seemed to lose his appetite. So I at once killed him, and sent 

 him for identification to Mr. Rilev, who named it for me. Both the draw- 

 ings of these two new insect friends are from the clever pencil of Mr. 

 Riley, who kindly permitted me to obtain electrotypes of them. 



I shall be glad to hear from any of the members of the Society residing 

 in Ontario, whether the Colorado beetle has done much damage in their 

 neighbourhood. In many places, I am aware, some mischief has been 

 caused, but the potato crop generally seems to have been an unusually 

 good one, even in those districts where the beetle was prevalent. 



I would also ask the members to keep a sharp look out for any para- 

 sites or other enemies which they may discover attacking the Colorado 

 larvae. We know already of sixteen, and we hope that the number may 

 largely increase. Any communications on this subject will be gladly 

 received. 



CHICAGO FIRE— APPEAL TO ENTOMOLOGISTS. 



Mr. J. Q. A. Warren, of England, recently residing temporarily in 

 Chicago, writes to us from St. Paul's, Minn., as follows : — " Having lost 

 my entire collection, by the fire in Chicago, of Entomological and other 

 Natural History specimens, the work of the past year in the West, as well 

 as of years abroad, I beg to solicit correspondence and specimens from 

 American. Entomologists for a new collection, for which I will send Euro- 

 pean duplicates as soon as I reach Europe,. My loss is heavy, over $3000, 

 and the patient labour of months. 



''Help me all you can, and I will appreciate it fully, and do all I can 

 in return. Address me at New York after Nov. 1st., care of Adams' Ex- 

 press Company, for parcels, and by mail to New York post office." 



Mr. Warren, we understand, had a very large collection in Chicago, 

 which he was intending to take back to England this winter, but it was 

 entirely consumed in the great fire. He is anxious to replace it, as far as 

 possible, before his return, which will be in December. We trust that all 

 our readers, who have it in their power, will assist Mr. Warren with speci- 

 mens, and enable him to take back a goodly representation of the Insect 

 life of this countrv.
