EREBIA II. 



EREBIA DISCOIDALIS, 4-6. 



Erehia Discoidalis, Kirby, 5- Fauna Boreali- Americana, IV, p. 298, pi. 3, figs. 2, 3. 1837. 



Male. — Expands 1.8 inch. 



Upper side dark brown ; primaries have a large castaneous patch, which covers 

 half the sub-median and all the median interspaces, as well as lower outer part 

 of cell ; costa next base freckled gray and brown, towards apex two or three 

 small gray patches ; secondaries immaculate ; fringes gray, on primaries brown 

 at ends of nervules. 



Under side of primaries brown, the castaneous patch repeated ; some examples 

 have this patch diffused so that nearly the whole wing is red ; over the hind 

 margin a gray bloom, which becomes strong next apex ; the whole costa mottled 

 brown and gray-white ; secondaries brown over basal half, mottled and streaked 

 in light and dark, beyond to margin gray, with many transverse brown streaks 

 interiorly ; at outer angle a gray-white patch, a smaller one a little nearer base, 

 another on the inner edge of the gray area in discoidal interspace. 



Body brown, the abdomen underneath gray ; the fore legs brown, the femora 

 of the middle and hinder pair brown, other joints yellow-brown ; palpi brown; 

 antennae imperfectly annulated red and gray, gray beneath ; club brown, fer- 

 ruginous below. (Figs. 4, 5.) 



Female. — Expands 2 inches. 

 Similar to the male. (Fig. 6.) 



Discoidalis was described by Kirby from Cumberland House, lat. 54°, sev- 

 eral specimens having been taken. In 1863, I received perhaps twenty ex- 

 amples from Mrs. Christina Ross, wife of Bernard C. Ross, Hudson Bay Company 

 agent at Fort Simpson, Mackenzies River, and I do not remember having seen 

 the species since, though many collections on both the west and east coast of 

 America have been submitted to me. Mr. James Fletcher tells me that but a 

 single example has been brought in by the late Canadian Government Expe- 

 ditions, and that was from Fort Simpson.
