 (Figure 1.'.7. (); 15«, F; IMJ, M; KiO. K. I.) 

 Body larger tlmn in the spi-fics, wliitisli vfllow to Vfllowisli ; wings yellowish 

 wliiti', often l)rownisli hy dense spotting: wing inenilirarie less corrugated. Struc- 

 lurally there is very slight differentiation. 



Deserihed from many males ami fiMi;i!es eolleeled in Colorado liv ('. F. Maker; 

 determined liy K. A. Sehw.-irz as identie.'il to Kiley's nianuseript forms of Aph. 

 nnnustipennis.

Described from numerous males and females collected by ('. F. Baker at I'agosa 

 Springs. Colorado. Distribution: In the C. F. Baker collections as follows: 

 Colorado. .Vrizona. California. Nevada, Wisconsin, I.iuiisiana. .\Iabama ; Louisiana 

 (F. C. Bishopp); Wyoming (C. W. .Metz). 



This species is very closely related to Aph. nerrnia Forst., a European species. 

 The principal diflferencc is in the wing membrane; in the F.uropean species it is 

 conspicuously transversely wrinkled, subhyaline and not flavous; in the American 

 species it is distinctly flavous and scarcely transversely wrinkled. 



Aphalara communis metzaria n. var. 



This variety is separated chiefly upon the presence of brown dots or spots in 

 the distal portion of the forewing. somewhat as in Aph. angustipennit Crawf.. but
