THE CANADIAN ENTOMOLOGIST. 103 



38. Thecla titus. — Common. Appearing about the middle of July 

 and flying a month or so, frequenting particularly the butterfly-weed. 



39. Chrysophanus thoe. — Common, especially in tracts of blue flag 

 from June 10th to the 1st of July, and from August 15th to the middle of 

 September. 



40. Chrysophanus epixanthe. — Very common at Lamberton Lake, 

 flying over tracts of shrubby cinquefoil (Potentilla fruticosa). I have 

 taken it from June 10th to September 19th, and it is common at all times 

 between, though I think there are two broods in reality. 



41. Chrysophanus hypophloeas. — Common. Flies from May 10th to 

 June 15th, from July 15th to August 15th, and again from September 20th 

 to October 9th, when I have seen worn specimens. It is thus apparently 

 three-brooded, but I believe that of the larvse from the summer brood 

 some mature and give imagos in the fall, while others go over to spring, 

 and that it is really two-brooded. 



42. Lyccena lygdamus. — Rare. Late in April and early in May along 

 muddy cow-paths. Very local. 



43. Lyccena pseudargiolus. — Form violacea is not common, appear- 

 ing in April and early May, while neglecta is a common form from June 

 10th to the latter part of August, and seems in some specimens to ap- 

 proach var. pseudargiolus. 



44. Lyccena comyntas. — Common in May on willow blossoms. Again 

 found from July 15th to August 15th, delighting in wet, muddy places in 

 woods. In 1890, fresh specimens were taken again September 20th, but 

 I believe these were disclosed from chrysalides which should have gone 

 over till the next spring. 



45. Pieris protodice. — Very common in fall from August 10th to the 

 end of September, but the spring form, verua/is, is rather rare, appearing 

 from the end of April to the middle of June. 



46. Pieris oleracea. — Not common. Low ground ; in May and again 

 in July and August. 



47. Pieris rapce. — Very common. Several broods, appearing con- 

 tinually throughout the season. The earliest of my dates is April 7th, 

 the latest October 13th. The species was here when I began collect- 

 ing in 1883 and I have taken it ever since. Am unable to give the date 

 of its first appearance. 



48. Meganostoma cce.sonia. — Formerly found here, I am told, but rare. 



49. Colias eurytheme. — Once seen, July 20th, 1886.
