14. Grapta interrogationis. — Common most years, some quite 

 abundant. Flies in early spring up to June 15th ; the larvae of the first 

 brood appear about the end of June, and the butterflies are on the wing 

 from July 10th to the end of the month ; a second brood of larvae is 

 found about that time, and these give butterflies from the iolh to the end 

 of August \ the third brood flies late in fall and hibernates. The hiber- 

 nating butterflies are mostly fabricii, while umbrosa is more abundant in 

 the summer broods. 



15. Grapta comma — Common. Flies from early spring to the first 

 of June, again, the form dry as, from July 1st to August 15 th. while the 

 second and hibernating brood appears late in the fall. 



16. Grapta progne. — Rather common. Early in spring, again in 

 July and August, and a second brood late in the fall hibernating. 



17. Grapta j-album. — Not common, though much more so than 

 formerly. Appears early in September, and flies throughout the fall and 

 again in early spring. Our hardiest butterfly, appearing at any time in 

 the winter that the weather is at all favourable. Under date of January 

 3rd, 1892, I have this note : " Coldest day of winter thus far, the 

 thermometer registering, at 7 a.m., n°, and though the sun shining 

 brightly all day, the snow only melting in sheltered spots. At 4 p.m. 

 took a G. j-album resting, wings erect, on the snow in the middle of the 

 sidewalk of a well-travelled street. Was chilled, but soon revived in the 

 house." All the Graptas, together with Van. antiopa, are common early 

 in the spring around trees from which sap is flowing. 



18. Vanessa antiopa. — Very common. Sometimes becoming a pest 

 by defoliating young elms. Usually three-brooded, the hibernators flying 

 from early spring to the end of May, the larvae of the first brood appear- 

 ing early in June, and the butterflies from the 10th of the month to the 

 20th of July ; the larvae of the second brood are found in the fore part of 

 July, the butterflies during August ; of the third brood, the hibernating 

 individuals, the larvae in September, the butterflies from September 20th 

 onward. 



19. Vanessa milberiii. — Common; inclined to be local. Three 

 broods, appearing as follows : The hibernating specimens from early in 

 spring to June 15th; of the first brood, the larvae during the latter part 

 of May and early in June, the butterflies from the end of June to July 

 15th; the larvae of the second brood in July, the butterflies during
