Further material will undoubtedly show others. It is possible that 

 we had originally two species, an Eastern (var. G) and a Western 

 (var. A) which have interbred to produce the intermediate forms; 

 but this is a mere guess. Careful and extensive rearings from known 

 parents will be necessary before we can determine the exact status 

 of any of the varieties. Until we have such, it would be very unwise 

 to make any new names or attempt any splitting of the species. 



Var. A (fig. 36). — Tegumen of male genitalia without posterior 

 projecting horns; aedoeagus with a long lateral spur reaching from 

 below middle almost to apex ; apex of spur bent over, broadened and 

 serrate. Color ranging from pale reddish brown to rosy gray broAvn. 

 Expanse : 13-20 mm. Distribution : California, Oregon, and Wash- 

 ington. Reared specimens from acorns. 



This is the typical Jatiferreanus. Kearfott's inquilina also goes 

 here. 



Var. B (fig. 32). — Tegumen without posterior horns; aedoeagus 

 with rather long spur, latter, however, not reaching to apex of 

 aedoeagus, smooth and pointed. Color as in variety A, but most 

 specimens rather pale. Expanse: 18-20 mm. Distribution: Utah. 

 None of specimens in collections reared. 



Var. C (fig. 33). — Tegumen developed posteriorly into two stout, 

 well separated, rather long, slightly roughened, partially curved 

 hornlike projections; aedoeagus simple. Color as in varieties A and 

 B. Expanse: 13-20 mm. Distribution: California, Arizona, New 

 Mexico. Reared specimens from acorns. 



Var. D (fig. 34). — Tegumen developed posteriorly into two very 

 short hornlike projections; aedoeagus with very short, pointed, 

 lateral sj)ur. Color, very dark red-brown; hind wing dark brown 

 with strongly contrasted white cilia; a rather strong black dusting 

 on forewing between the metallic cross bars. Expanse : 15-20 mm. 

 Distribution : Pennsylvania, Virginia, Connecticut. The only reared 

 specimens are a couple in the National Collection (Hopk. U. S. 

 No. 12106 Falls Church, Va., July 10 and 25, 1914, Heinrich) bred 

 from chestnut husks. 



The most distinct form so far as color is concerned. There is a 

 pale Nevada form, however, with similar genitalia. 



Var. E. — Tegumen as in variety A; aedoeagus as in variety B. 

 Color, reddish brown. Expanse: 11-13 mm. Distribution: West 

 Virginia, Pennsylvania, Illinois. Reared specimens from beech nuts 

 (Quaintance No. 7590, French Creek, West Virginia, F. E. Brooks). 

 Collected adults from Pennsylvania and Illinois intergrade between 

 this and the following variety and are difficult to place. 



Var. F (fig. 35). — Genitalia as in variety E except that posterior 

 projections of tegumen are straight and longer. Color yellow or
