410 THE CANADIAN ENTOMOLOGIST 



types from the collection of Mr. and Mrs. Reynolds. The speci- 

 mens were caught by Mr. Nunenmacher at Blue Lake, Humboldt 

 Co., California. Other slightly less typical specimens are in Dr. 

 Calvert's collection from Seattle, Washington. This variety is 

 probably a member of the fauna of the narrow, very humid coast 

 strip extending from northern California to southern Alaska. 

 Various other species have dark forms in this humid belt. In 

 the collection of the U. S. Biological Survey in Washington, D. C, 

 are a male and a female Agrion cequahile collected on the Owyhee 

 River, at Rome, Malheur Co., Oregon, which are intermediate 

 between var. yakima and var. calif ornicum . These are from south- 

 eastern Oregon. The writer had thought at first that the var. 

 calijornicum might be a Pacific Coast extension of var. hudsonicum, 

 but since the Malheur Co., Oregon, specimens have come to light 

 it seems more closely related to var. yakima.

NOTE ON AGRION .EQUABILE HUDSONICUM (HAGEN). 



Mr. Kennedy has asked me to add any remarks to his paper 

 on Agrion cequahile that I might think desirable. I have only the 

 following note to make concerning the race hudsonicum. 



I have four much broken males of A. cequahile from the Keno- 

 gami River, Ont., on the Hudson Bay slope, north of Lake Superior, 

 taken by Mr. W. J. Wilson in 1904. They were all taken within 



December, 1918
