403. A. excelsa Ottol. — I have no local captures in my collec- 

 tion, but several from Banff, July 30th-August 19th (Sanson). 

 Under the description Dr. Ottolengui mentions having three speci- 

 mens from Laggan, and claims to have seen many more from there. 

 I have one from Field, B.C., and a few from Kaslo. My series are 

 all much alike, and one or two agree concisely with Ottolengui's 

 figure. I have angulidens from Colorado, and, though closely 

 allied, I believe they are distinct. The difference was pointed out 

 by Ottolengui. I would say, in addition, that whilst in angulidens 

 the outer stroke of the U portion of the sign is evenly out-curved, 

 the outer stroke of the V in excelsa is either direct or in-curved for 

 the lower two-thirds of its length. In both it has generally a 

 slight inward hook at the tip. Vaccinii appears to be another very 

 close ally. There was a series of that in the Washington collection 

 from the White Mountains, N.H., in which the sign seemed to me 

 very variable. Also associated with them, justly as far as I could 

 judge, was an unset Kaslo specimen, recorded by the name in the 

 Kaslo list. I have suspicions that this specimen was really excelsa. 



I have what I feel sure is another slightly larger closely allied 

 species from Kaslo and Nelson, B.C., which was recorded in the 

 Kaslo list as ''u-aurenm Guen." but which was sent me subsequently 

 by Mr. Cockle as "u-aureum of the Kaslo list, but excelsa by Dr. 

 Barnes, compared with Ottolengui's naming." I feel sure that 

 excelsa is wrong for this form, and I am by no means satisfied 

 that it is u-aiireum. Compared with both excelsa and angulidens, 

 it has a wider open sign; in fact, more rectangular than V or U- 

 shaped. I may call it a more octoscripta-Vike sign, more resembling 

 that of arctica than of any other of Ottolengui's figures. The 

 outer spot is in every specimen larger than in excelsa, and some- 

 times hollow — that is to say, dark filled centrally, and more often 

 touches the outer line of the larger sign at varying points. It is a 

 slightly larger species, but as regards the rest of the maculation 

 and color of the primaries, there is really very little difference. 

 The secondaries differ, however. In excelsa the secondaries may 

 be described as dull fuscous, with a broad but ill-defined yellowish
