Bibliographical citation same as for species. 



In this description the "color markings" of the key are assumed to be 

 the ground color. In variety vulnerata this varies from greenish brown to 

 fulvous and is relieved by the following pale areas and color markings; an- 

 terior margin of vertex, a vitta bordering each eye, and a median vitta ex- 

 panded in front which is more or less continuous over vertex, pronotum and 

 scutellum; pronotum with a curved pale vitta and interior pale spot on each 

 side, scutellum often j^ale yellowish or reddish laterally, clavus with a large 

 irregularly lunate whitish In'aline sjwt on inner side at base, sometimes divided 

 and a smaller one beyond middle; corium whitish hyaline between sectors, 

 a well defined spot near posterior claval si^ot; costal i:)laque ojjaque whitish, 

 marked off at each end by an oblique dark line; middle part of costal margin 

 narrowly yellow, a pale area behind costal plaque and of about the same color 

 interrupted posteriorly by red streaks on the first cross- vein and first sector; 

 other cross- veins, apical veins and the sectors more or less pale; apical cells 

 and adjacent tegminal surface the other side of cross-veins, smoky to black, 

 crossed near apex by an oblique hyaline band, second cell with an additional 

 hyaline spot near base, and the first chiefly hyaline within. Underside 

 chiefly slaty, upper part of face livid to yellowish, legs stramineous to yellow, 

 edge of abdomen pale yellow.

 OH 15; pronotum: L 10, W 20; tegmen 12-58. Measurements from a 

 female, Plummer's Island, Maryland, Nov. 4, 1906, (W. L. McAtee).

Specimens from the west, which may prove, ultimately, to deserve .sub- 

 specific recognition, have the pale areas of the tegmina notably more extensive, 

 and the color markings yellowish to orange-red; underside much paler, iaco 

 and genitalia sometimes entirely pale yellow.
