cells dusky. The principal variations are that narrow slaty-drab vittac and 

 edgings may mark the places where more extensive pale areas are present 

 in variety obliqua, or the tegminal vittae may be well separated as in typical 

 form; the inner apical cells are quite black sometimes, continuing the dorsal 

 stripe to apices of tegmina. 



Length, 2.57 mm.; vertex: LM 7, LE 3.5, WA 12, WP IS, OA 6, OP 10, 

 Oil 14; pronotum: L 10, W 18; tegmen 12-53. Measurements from a fe- 

 male; Hutchinson, Kansas, Oct. 23, 1914, [U. S. N. M.]. 



Other specimens examined are from Plummer's Island, and l^ranchville, 

 Maryland; Mount Vernon, Virginia; Oxford, Indiana, and Clarksville, 

 Tennessee, [W. L. M., U. S. N. M.]. 



Erythroneura obliqua var. dorsalis Gillette dark form 



Like dorsalis except that the ilorsid stripe is black on head, jironoluni and 

 scutellum, remaining red or reddish, at least in part, on tegmina. This is a 

 very pretty variety as the black anterior part of the stripe is strongly con- 

 trasted with pale j^ellow margins from humeri forward, while the tegmina 

 exterior to stripe are whitish hyaline, the costal plaques denser white; apical 

 cells or a little more of apical parts of tegmina dusky. Face sometimes 

 with a median dark vitta expanded into a triangular mark on lower sitle of 

 vertex. 



Length, 2.97 mm.; vertex LM 7, LE 3, WA 12.5, WP 19.5, OA 6, OP 12, 

 OH 16; pronotum L 12, W 21; tegmen 13-62. Measurements from a 

 female; Branchville, Maryland, April 2, 1915, on Pinus virginana, (W. L. 

 McAfee). 



Other specimens examined are from Montgomery County, Maryland, 

 and Mt. Vernon, Virginia, all from the same species of pine, (W. L. M.). 



Erythroneura obliqua var. stolata new variety 



Dorsal stripe continuous, not obviously made up of distinct vittac, entirely 

 dusky to black, darkest anteriorly; in the type all other parts of dorsal sur- 

 face are pale yellow, more or less overlaid by pruinosity, densest around 

 margins of costal plaques; the pruinosity in dilute form extends even on the 

 dorsal stripe; apical cells wholly dusky; other specimens are less pruinose 

 and show some tendency toward a dark vitta on face. 



Length, 2.87 mm.; vertex: LM 8, LE 3.5, W.V 12, WP 19, OA (i, OP 10.5, 

 OH 16; pronotum, L 11, W 20; tegmen 13-59.

Erythroneura obliqua var. aucta new variety 



Dorsal stripe bright red along edges, fading to pale red or dusky within 

 and more or less evanescent posterior of clavi; vittae the fusion of which
