THE CANADIAN ENTOMOLOGIST. 85 



pus on 3rd, 4th May (1887) at lilac blossoms, and that at the date of 

 writing, June 27th, fresh males of the first brood of the imago were flying. 

 Mr. Marsh says that at Randolph, Vt., far to the north, a fresh male was 

 seen a week later, on 4th July. 



On 1 6th August, Miss Morton wrote that a new brood of the butterfly 

 was flying in abundance. Mr. Marsh says that at Randolph, 2 °. , 1 $ , 

 perfectly fresh, were taken 1 1 th August. 



On 20th Sept., Miss Morton wrote : " Fresh examples are emerging 

 every day now, and there are numbers of them in the clover field." Mr. 

 Marsh says : " From 30th Sept. to 15th Oct., butterflies from pupae bred 

 from said larvae emerge, and besides, many pupae were found in the fields 

 and the imagos came from them." So running parallel to Miss Morton's 

 account. 



On 9th Oct., Miss Morton again wrote : " On 6th and 8th of this 

 month, we saw numbers of perfectly fresh examples of Archippus. We 

 caught several, and in some the wings were still quite fresh, showing their 

 recent advent from chrysalis. On none were there any signs of age." And 

 she adds : " These are doubtless the hibernators." Mr. Marsh had 

 imagos out of bred pupae so late as 29th Oct. and 4th Nov.; and saw but- 

 terflies on the wing on 5th and 13th Oct. The history is identical in New 

 England and eastern New York. 



Years ago I followed up the life history of Archippus carefully in West 

 Virginia, and in Psyche, vol. 2, p. 169, 1878, and Can. Ent., xiii., 211, 

 1882, I showed that the hibernators of this species came out of winter 

 quarters as early as other hibernating butterflies, and with them gathered 

 about the first blossoms of the year, which here are on the wild plum and 

 cherry trees ; that eggs were to be found, and old females were to be seen 

 ovipositing on milkweeds but just out of ground ; that in a very short time 

 the old hibernated individuals had totally disappeared, undoubtedly dying 

 soon after laying their eggs, as is the invariable rule with butterflies ; that 

 within a month a generation fresh from pupae was flying ; and that so, 

 certainly three, possibly four, generations of the butterfly followed the 

 hibernators. In fact, that the habits of Archippus were in no way abnor- 

 mal, nor was the species so long lived as others where there is but one 

 brood per year in descent from the hibernators (as for example, in Grapta 

 Faunus). 



I made observations myself here at Coalburgh last season, to some 

 extent, on this species. I found an egg 10th May, on an Asclepias but
