THE CANADIAN ENTOMOLOGIST, 219 



GRAPTA INTERROGATIONIS, ETC. 



This insect is not by any means abundant in my neighbourhood, and 

 for several years I only captured one or two of the pale variety 

 Fabricii. About four or five years ago I saw a worn female of that 

 variety depositing eggs upon a wild hop I had trained over the front of 

 my house. I did not subsequently see any other female near the plant. 

 I left the larvae upon it until they were nearly full grown, when I 

 collected about a dozen. I think they all hatched out safely, and the 

 result was about one-third of the dark form Umbrosa to about two- 

 thirds of the pale. The larvae were all of a size, and pupated within a day 

 or two of each other, so I think it reasonable to suppose they were all 

 from the eggs I saw being deposited, and from one and the same mother. 

 Never having before seen or taken the dark form, and not then having 

 any book upon Canadian butterflies, I was rather surprised at the result. 

 On looking over my notes for last year I do not see anything of special 

 interest, except that I took a specimen of Chionobas vartttia on 21st 

 June, and the only one that I saw. The occurrence here of Colias 

 ccesonia has already been noted. 



Owing to a conversation I had some time ago with Dr. Fletcher, I 

 paid particular attention to Colias eiirytheme and its varieties. I did 

 not detect a single instance of Eriphyle " in coitu," or even flirting with 

 other than its own female, though there were many flying about of the 

 early small yellow form of Eurytheme and also of Keewaydin, nor 

 vice versa. 



Neither did I notice any intercouse between Eriphyle and the large 

 orange form Amphidusa, Scudder, but the males of each variety 

 seemed to single out the corresponding females of that variety. I am 

 aware I am venturing upon dangerous ground, but so far as I am able to 

 judge from observation, I should certainly say that Eriphyle was a 

 species distinct from Eurytheme. Unfortunately, I am unable to give the 

 time required to the rearing of the large number of larvae necessary to 

 the determination of this question. What I want particularly to convey 

 is that I have never noticed promiscuous intercourse between the 

 different broods, if such they are, though they overlap each other, and 

 are flying at the same time. E. Firmstone Heath,
