CORRESPONDENCE. 



CARABUS AURATUS. 



Deal- Sir : Mr. Grote's reference, in your June issue, to Dr. Harris's 

 observation on Carabiis atirattis, deserves some attention. The " Insects 

 Injurious to Vegetation" was one of my early helps to an introduction to 

 Entomology, and in reading the passage referred to, I was led, in my in- 

 experience, to speculate upon the probability of meeting with the beauti- 

 ful beetle mentioned. 



Many years ago Mr. P. S. Sprague showed me the specimen itself in 

 Dr. Harris's collection, now in the care of the Boston Natural History 

 Society, and told me that he had been led to surmise that this was Dr. 

 Harris's first insect capture, and that it had been the means of turning his 

 attention to the study and observation of insects, with the excellent result 

 so familiar to us all. It is hardly necessary to say that the identification 

 was correct, but the specimen was an entirely accidental introduction, and 

 did not perpetuate its species. 



It seems to me that it would be very desirable if those having a 

 knowledge of the accidental occurrence of foreign insects in our country 

 would publish the particulars.

PAPILIO CRESPHONTES. 



Dear Sir: On May 8th, I observed four caterpillars of Papilio 

 Cresphontes about two-thirds grown feeding on the Lombardy Poplar 

 ( Populus dilatata). The Cresphontes has been increasing rapidly since 

 its first appearance in this locality in 1878. Its caterpillar has hitherto 

 seemed to be restricted to plants of the Rue family. Leaving the Orange 

 of the Southern States, it came north to feed upon the Prickly Ash 

 (Xathoxyhim Americanum) and Hop-tree ( Ptelea trifoliata). Both 

 these being scarce in this locality, it has taken to the Lombardy Poplar. 

 It may be remarked that Populus is botanically widely separated from the 

 Rutacece. W. P. Shannon, Greensburg, Indiana.

THE ANNUAL MEETING. 



The Annual Meeting of the Entomological Society of Ontario will be 

 held in London during the month of October. The exact date is not yet 

 decided upon, but it will be announced in our next issue.
