on primaries instead of two, longer and rather niuie heavily pectinated 

 antennae, and much less black on secondaries. Of my ^ Mr. Gibson 

 said, "May be Bolaiideri., but may simply be a variety oi deten/ii/iata." I 

 hardly think it is the latter. 



123. A. Nevadensis, G. &: R. , var. incorrnpia, Hy. Edw. — So far I 

 have only taken two $ ^ and two 9 9 > .Uily 7'1'> to Aug. 6th. The $ ^ , 

 on Aug. 6th, were taken at Calgary town lights. A third 9 , June 28ih, 

 1899, has primaries marked as incorrupta, but has pure black secondaries 

 and a black" body. I have two ^ Nevadensis froni Glenwood Springs. 

 Colo., which look quite a dififerent species. In fact, they come very much 

 nearer to Blakei, from the same localit'^', than to Calgary incorrupta, 

 sjiecimens of which have been seen by both Dr. Dyar and Mr. Gibson. 



124. A. Wi/liamsii, Dodge, var. determinata, Neum. — Common. 

 End of June and July. In one specimen there is no trace of the 3rd 

 transverse band ( = typical IViilianisii ?), and the 4th and \V marks are very 

 faint. I have no 9 ? > unless those mentioned above under Bolixnderi 

 belong to this species. The ^ antenna; are sometimes variegated, black 

 and cream. 



125. A. celia, Saund. — Banff, June i6th (Sanson). On the authority 

 of Mr. Gibson. I have never to my knowledge seen a specimen. 



126. A. sp. — A series of nine specimens have been a puzzle alike to 

 Mr. Gibson and Dr. Dyar. Seven (^ ^J and one 9 vvere taken near 

 Billings's lumber mill on June 19th and 26th, 1898, and a $ is from Black- 

 falds, taken by Mr. Gregson on Aug. 9th, 1902. I believe the series to 

 represent one extremely variable species. Four ^ ^ somewhat resemble 

 IVil/iamsii in maculation, but are smaller and much blacker. Two ^ ^ 

 and two 9 9 ^^e like miniature virguncula. I have not taken the species 

 for several seasons. 



127. Farasefnia p/aniaginis, Linn. — Not common on creek bottoms 

 on the hill-prairie. Common in the spruce and vvestv/ard to the mountains. 

 End June and July. I have specimens like all the varieties listed in Dyar's 

 and Smith's lists except Geddesi. An interesting article on Laggan 

 petrosa, by Mr. Bean, will be found in Can. Ent., XXVII., 87, and Fl. II. 



128. Halisidota maculaia, Harr. — A single $ at light, June 25th, 

 1898, was all I ever saw of this species until last year (1903), when I found 

 the decidedly conspicuous larvae common on different species of poplars in 

 gardens in Calgary. These pupated in September, and moths emerged in 

 the house at the end of February of the present year,
