70 THE CANADIAN ENTOMOLOGIST 



8 — " thanatologia,waiV. sordida,(^ . Calgary. The colour is 



dark red brown, and the specimen has been com- 

 pared with the 9 type, and is very like it, but the 

 type is more ochreous, and has sharply defined s. t. 

 dashes. It is the largest & I have taken. 



9 — " thanatologiay var. perfida 9 type High River, Alta. 



(Baird.) The specimen is characterized by lack of 

 any contrasts. 



10 — " thanatologia Dyar, var. sordida, 9 . Calgary. Like 



some perfida in colour with the addition of numerous 

 fine black markings. This is one of the actual 

 specimens named "terrealis" for me by Smith, and 

 referred to in my All)erta List under that name. 

 (Can. Ent., XXXVI 1, 51, No. 225, Feb. 1005.) 



11 — '* thanatologia, var. 9 . Calgary. Rather pale grey, 



with black and sienna brown lines and shadings. 

 This has been compared with the 9 type of boretha, 

 and is not unlike it, but greyer. It was also com- 

 pared with type thanatologia. See remarks under 

 fig. 2. The actual resemblance of No. 11 is to some 

 forms of aiixiliaris. I have another Calgary speci- 

 men almost exactly like it, but with longer sub- 

 terminal black dashes. Mr. Cockle has specimens 

 very like this. 



It is strange that out of nine imagines bred from No. 1 

 four of them w^ere rather sharply distinct in appear- 

 ance from any previously taken at Calgary, viz., 

 Nos. 2, 3, 5, and one like 7. 

 12 — Copablepharon viridisparsa Dod. cf type.
