THE CANADIAN ENTOMOLOGIST 13 



found it at Echo Lake from June 30 to July 20. Dr. Allen took one 

 at Intervale on July 4 in the Saco meadows. 



37. Anax Junius Drury. 



July. I saw one at Streeter Pond, Franconia, on July 3. Mrs. Slos- 

 son reports one on the Gale River on June 20. 



38. Aeshna canadensis E. Walker. 



July and August. Recorded from the "'White Mts." by Shurtleff. 

 Dr. Calvert took it at the White Mt. House, at Franconia, and at 

 Fabyan's. I found it common at Mill Pond, Lyman, on July 29. 



39. Aeshna constricta Say. 



August and September. It was taken at Hermit Lake, and Fabyan's 

 by Dr. Calvert, and by Dr. Allen at Carter's Notch, and Intervale from 

 August 21 to September 18. It is probably that some of the latter 

 material should have been referred to A. umbrosa, a closely related 

 species since described. 



40. Aeshna cremita Scudd. 



August. The type was taken at Hermit Lake, Mt. Washington, by Dr. 

 Scudder, and it was also taken there by Mrs. Slosson, and a specimen of 

 her collecting is in the U. S. N. Museum. I took it at Profile Lake 

 August 12, 1916, and it was common at Lonesome Lake, Lincoln, on 

 August 1. L^ndoubtedly undetermined material collected in July to 

 September at Carter's Notch by Dr. Allen belongs here. 



41. Aeshna juncea Linn. 



August. It was recorded from the "White Mts." by both Scudder 

 and Hagen. Mrs. Slosson also took it at Franconia. 



42. Aeshna ccerulea septentrionalis Burm. 



It was recorded from the "White Mts." by both Scudder and Hagen. 



43. Aeshna umbrosa E. Walker. 



August. Mrs. Slosson took it at Franconia, and a specimen collected 

 by her is in the U, S. N. Museum. It was recorded from the "White 

 Mts." by Sprague, and from Hermit Lake by Scudder. I took a 

 specimen at Lonesome Lake, Lincoln on August 1, and one in Franconia 

 on the same day. 



44. Aeshna verticalis Hagen. 



July to September. Dr. Allen took it at Hermit Lake, Mt.^ Washington ; 

 at Carter's Notch; at Intervale and North Conway from July 22 to 

 Sept. 11. In view, however, of the southern range of this species it 

 would seem probable that his specimens were misdetermined. A. 

 canadensis, a very closely related species, undescribed in 1899, was- 

 probably the insect captured.

45. Macromia ilUnoiensis Walsh. 



June. Dr. Allen took a male at Intervale on June 18. 



46. Dorocordulia libera Selys. 



Mrs. Slosson took it in Franconia. 



47. Helocordidia iihleri Selys. 



June. I took a male on June 25 at Echo Lake, Franconia.
