 at Eastham in June, 1904. Since the species was described in 

 1895 by Dr. Morse from Sherborn, Mass., its range has been 

 extended to Meredith Neck, Lake Winnepesaukee, by the 

 author in 1916; to Eastham and Manomet, Mass., by Mr. 

 Johnson in 1904 and 1905; Mt. Desert, Echo Lake, Maine by 

 Mr. Johnson in 1918, where it was again taken by Mr. D. 

 Merrill in 1919. Until this summer no female had ever been 

 captured. In sweeping the marginal grass swale along the pond 

 I captured one female which may be described as follows: 

 Cuneiform bluish post ocular spots not completely connected. 

 Vertex, a mid-dorsal thoracic, and a humeral stripe iridescent 

 black, rest of thorax bluish. Abdomen bluish with dorsum of 

 segments 1 to 10 with a broad iridescent black stripe widening 

 into distal semi-rings on segments 1 to 7. Legs black above.
