282 NEARCTIC ERYTHRONEURA (hOMOPTERA) 



Erythroneura obliqua var. fumida Gillette, yellow form 



Like variety fumida Gillette, except that the color vittae of tegniiiia are 

 golden yellow, and those of anterior parts yellow more or less overlaid by red; 

 veins and margins of tegmina beautifully pencilled in red; costal plaques 

 opaque whitish. 



Length, 3.1 mm.; vertex: LM 6, LE 3, WA 12, WP 20; OA 7, OP 14, 

 OH 16; pronotum L 12, W 21.5; tegmen 14-65. Measurements from a fe- 

 male; Maywood, Alexandria County, Virginia, Jan. 2, 1916, (W. L. McAtee). 

 Other sjiecimens were collected near Benning, District of Columbia, and 

 Branchville, Maryland, all on Pvnus virginiana, (W. L. McAtee), [W. L. M.]. 



Erythroneura obliqua var. electa new variety 



The vitttie on head and pronotum of this variety lack the usual high colors 

 and vary from dull greenish yellow to slaty; the tegminal vittae are about 

 typical in form, but are duller red than in variety obliqua, and are somewhat 

 obscured by the general duskiness of tegmina, to which however the follow- 

 ing areas are exceptions: whitish costal plaques (when developed), two long, 

 triangular areas on inner margin of clavus; and separated very sharply, the 

 clear third and fourth a]:)ical cells. General color of body slaty, margins 

 of abdominal s(>gments pale greenish yellow. 



Length, 2.54 mm.; vertex: LM 7, LE 3, WA 10, WP 15.5; OA 4.5, OP 8, 

 OH 13; pronotum L 9, W 12; tegmen 11-50. 



Type — 9 ; Maywood, Alexandria County, Virginia, March 12, 

 1916, (W. L. McAtee), [W. L. M.]. Allotype- - c^ ; same local- 

 ity, February 20, 1916, (W. L. McAtee), [W. L. M.]. 



This form differing from all the varieties of Erythroneura ob- 

 liqua in having two of the apical cells hyaline, and sharply mark- 

 (h1 off fi-om the remainder of tegmen, may be a distinct species. 



Erythroneura rubroscuta Gillette 



Typhlocyba rubroscuta Gillette, C. P. Am. Typhlocybinae, 1898, p. 755. 



[Onaga, Kansas.]. 



Ground color of head and thorax pale yellow, of tegmina whitish hyaline; 

 with the following pinkish red markings: scaitellum (i)aler medianly), an 

 oblique narrow band on each tegmen across apical third of clavus and running 

 to or nearly to costal plaque, lines on some of the veins especially the cross- 

 veins and on base of costa, flecks on pronotum and head, in the form of in- 

 verted V-shaped marking, the rami of which are broad on (about one-third 

 the width of) pronotum uniting to solidly occupy all of pronotum except a 

 small semicircle on anterior margin; face sometimes with pinkish-red mark- 

 ings tending to be transverse; costal plaques whitish to j'ellowish. 



Length, 3.2 mm.; vertex: LM 7.5, LE 3.5, WA 14.5, WP 22, OA 6.5, 

 OP 13, OH 18; pronotum L 12, W 23; tegmina 14-70.
