A female specimen from Hampton, N. H., collected by Mr. 

 S. A. Shaw is 4 mm. long; thorax with indications of three 

 pale brown confluent stripes; fore metatarsus one-fifth shorter 

 than the tibia; subcostal vein ends nearly opposite base of the 

 radial sector; the subcostal crossvein is situated about the 

 length of the humeral crossvein beyond the latter; the tip of 

 Ri+5 and costa very faintly tinged with brown ; coalesced part 

 of media about half as long as its petiole ; anal vein prolonged 

 to the margin. Excepting for the brown tinge near tip of wing 

 these characters are also possessed by the type In the museum

A female specimen from Blue Hills, Mass., collected by Mr. 

 C. W. Johnson, in July is similar but thoracic stripes are more 

 distinct, the brown on the abdomen more extended, and without 

 a suggestion of brown near tip of wing. 



Some defective specimens from Wisconsin, Oregon and 

 Ithaca, N. Y., seem also to belong here.
