Erythroneura pyra McAtee 



Erythroneura pyra McAtee, W. L., Proo. Biol. Soc. Wash., 37, p. 133, Dec. 29, 1924 

 [Berwick, Iowa]. 



Closely allied to E. hartii Gillette, and copying it in markings, except 

 that the red markings surrounding the pale saddle-spot are confined to 

 clavus anteriorly and extend no farther posteriorly than costal plaque, 

 whereas in E. hartii they cover the corium also, and extend to the cross- 

 veins or beyond. 



Inner clasper angulate inwardly, then outwardly, the angles more or 

 less acute, the inwardly angling apical process slender and acute ; process 

 of 9th segment long, slender, bowed outwardly subapically, where it is 

 armed below by a large aciculate process, ape.x also aciculate; aedeagus 

 stout, shaft shorter than the basal cavity. Length, 3 mm.

 ander. Yellow-marked forms, Urbana, III, April 23, 1919, April 29, 

 May 1, 1920 ; in copula the latter date. 



The following comparative statement about the genitalia of E. hartii 

 may be made : Inner clasper rather the shape of a human lower leg, 

 with the knee, heel, and toe more or less acute; process of 9th segment 

 simply decurved, falcate, thinner apically as viewed from above ; aedeagus 

 slender, recurved apically, shaft much longer than the basal opening. 



Erythroneura mitclla new species 

 In venational characters this species belongs in the same group (IV 

 of my paper on the genus. Trans. Am. Ent. Soc. 46, 1920, pp. 269-271) 

 as E. pyra, but the coloration is much like that of some varieties of E. 

 comes Say, as a heavily marked specimen of var. vitifex Fitch. Ground 

 color of head and thorax pale yellow, of tegmina hyaline whitish. Vertex 

 with yellowish to reddish curved lines near eyes, and forming a more or 

 less ovate marking in middle ; pronotum with an irregular Y on disk, and 

 a heavy triangle on each anterior angle orange-red; basal triangles of 

 scutellum yellow, outlined by red, apex red ; tegmen with a broad band 

 from costal plaque to commissure, narrowing on clavus over about the 

 middle of which it forms an oblique marking, and a narrow band on 

 clavus only at a point one-fourth from apex, pinkish red ; a longitudinal 

 vitta along outer margin of clavus basally is yellowish red ; a triangle on 

 costa near base of corium, orange-red and a band from posterior end of 

 costal plaque to crossveins scarlet, a more or less inclosed oval area, and 

 the costal border whitish. A dark spot in hind end of costal plaque, and 

 in base of fourth apical cell.
