THE CANADIAN ENTOMOLOGIST 239 



" I can't distinguish them from vaccinii,''oi which there was a 9 from 

 Mt. Washington. About this specimen I wrote: "Darker than 

 the u-aureum series, but seems to me exactly like it." My sketch 

 of the sign of the three specimens shows that it was exactly like 

 some in my unknown species, which I call ''u-aureum of the Koc- 

 tenai list." But in February, 1912, I compared a Nelson, B.C., 

 specimen with them and do not seem to have found that they 

 matched it. This time my notes read: "The u-aureum of this 

 collection is not improbably zeta Ottol., judging by the figure of 

 the type of that, though the t.a. (in u-aureum) seems less even, 

 and in none does the outer spot join top of sign. Secondaries are 

 alike exactly, but basal area of primaries seems paler in zeta." 

 The description of the latter was made from a single 9 from" North 

 West Territory" and came from Mr. Jacob Doll's collection. I 

 have nothing to match it exactly, but it appears to be of this group. 



406. A . falcif era Kirhy — Dr. Ottolengui's remarks on this 

 species appear correct. Kirby described the grey form from Nova 

 Scotia, and simplex, of which the type is a female in the British 

 Museum, from Trenton Falls, N.Y., is a very dark brown specimen. 

 I have tried hard to recognize two species in these forms, noticing 

 that most falcifera seemed to have a smaller and more slender sign. 

 This difference is not constant, however, and I must admit that 

 I can discover no other means whatsoever of separating them 

 except by color, in which they grade easily through. 



It seems hard to believe that simplicima Ottol., described from 

 a single female from the State of Washington, is anything more 

 than an unusually small simplex, with a sharp-pointed sign. His 

 remark that the sign is "always knobbed in falcifera and simplex'' 

 is not correct. I have a Calgary falcifera in which it is sharp, though 

 not quite as sharp as in the right wing of his figure of simplicima. 



407. A. orophila Hamps. — Sir George Hampson, in Can. Ent. 

 XL. 105, March 1908, thus named the Rocky Mountain form pre- 

 viously passing as diasema. The description was made from six 

 males and a female from Brobokton Creek, Alberta Rockies, and 

 one male from Early Winter Creek, Washington Forest Reserve, 

 all taken by Mr. Nicholl. The type is a male from the former 

 locality, and is marked as taken at 5,500 feet, on July 10th, 1907.
