Erythronetira abolla var. lemnisca new variety 

 Like E. abolla var. acccnsa yellow form, except that the scutelkim, 

 and disk of pronotum and vertex are occupied by a broad dusky vitta. 

 In the paratype, the coloration of tegmina anterior to crossveins has hardly 

 any reddish in it (in this respect resembling var. iconica) but this may be 

 due to incompletion of the coloring process. Length, 3 mm.

Meredosia, May 29, 1917; Dongola, May 10, 1917, May 12, 

 1916; Metropolis. Aug. 18, 1916; Forest City, April 3, 1917. This addi- 

 tional material reveals that this species has a red-marked form, the prin- 

 cipal vittae of tegmina, the markings on head and pronotum, and even the 

 scutellar triangles in some cases being red, usually of a bluish cast with 

 purer red edgings. 



Erythroneura rcpctita new species 



Belongs in Group 4 of my 1920 paper (Trans. Am. Ent. Soc, IC, pp. 

 269-271, Aug. 20, 1920), and is nearest to E. mallochi Mc.\tee in form, 

 venation, and coloration. Ground color of vertex pale yellow, with an 

 irregular vitta each side the median line deeper yellow ; pronotum pale yel- 

 low overlaid by olive-brown except for anterior margin, a spot on each lat- 

 eral margin, and three ovoid spots across disk ; scutellum yellow with the 

 basal triangles blackish, and two discal spots brownish ; tegmen whitish 

 hyaline with the base faintly dusky, a broad band from costal plaque, 

 across corium and clavus, widening slightly toward the commissure, and 

 apical cells except their extreme bases, a spot on costa in middle of cell 2, 

 and apices of cells 3 and 4, dusky. Front bordered laterally by dusky 

 stripes, and clypeus dusky basally as in E. mallochi. Under side of 

 thorax, a band across base of dorsum, and apex of ovipositor, black ; 

 apex of dorsum brownish; abdomen otherwise, and legs and under side 

 of head pale yellow. Length, 3 mm. 



The holotype female was loose in one of the boxes in which the col- 

 lection was received, so can be labeled only Illinois.
