On comparing European specimens of this species with our 

 saratogensis, I cannot find any characters of specific importance 

 differentiating the two. This observation also has been made 

 l)y Loew.i^ However, there are some sHght differences in the 

 maculation of the wings, which may be individual, but which I 

 prefer to consider at present as of subspecific value, and so retain 

 Fitch's name for the American subspecies. 



This species, sensu latiore, may be briefly characterized as 

 follows: The costal cell almost completely and evenly infuscated; 

 the fuscous spots of the other cells do not transverse the cell, 

 but are interrupted by the longitudinal streak and are much 

 narrower than the intermediate clearer spaces. The mesonotum 

 has a Inroad median yellowish stripe between two broad gray 

 ones, and laterad of these a distinct brown stripe along the lateral 

 margins. Notopleural stripe gray. These stripes are most easily 

 distinguished from behind. 



I have not seen any specimens of the typical form in ovu' fauna. 

 It has the ej^es horizontally oval ; costal cell uniformly infuscated, 

 without any suggestions of darker spots along the second vein, 

 the infuscation however evanescing basally. Furthermore, the 

 infuscation of the entire wing becomes evanescent at or about 

 the small cross-vein.

In this form we have the following characters of differentia- 

 tion: 



cf , 9 . Eyes nearly round; second antennal joint as long as, or longer than 

 third. The fuscous spots and costal infuscation extend basally as far as 

 the auxiliary vein, whereas in the typical form these are evanescent at the 

 small cross- vein. The darkening of the fore legs sometimes extends nearly 

 to the base of the tibiae. Length. — 4 to 6 mm. 



Originally described from Saratoga, New York.
