184 THE CANADIAN ENTOMOLOGIST. 



equally divided, I am not aware that I have yet seen a Calgary $ of 

 niultilhiea. But I have compared a 9 from Cartwright, Man., kindly 

 loaned me by Mr. F. A. Merrick, of New Brighton, Pa., who also sent 

 me a $ from the same locality. The two specimens are practically 

 alike, and resemble the Calgary form in every detail. 



338. L. commoides, Gr. — Common. July and early Aug. Easily 

 separable from any of its allies known to me by the uniformly dark smoky 

 secondaries in both sexes. The darkest shadings on the primaries are 

 black, instead of brown as in multilifua, but some specimens are very like 

 the Calgary forms of that species and of anteroclara when the wings are 

 closed. A distinctive feature not mentioned in the " Revision," but well 

 shown in Dr. Holland's figure, is the narrow dark shading, sometimes 

 faint, but more usually rather prominent on upper margin of median vein. 

 Eastern specimens do not seem to differ. 



339. Z. anteroclara, Smith. — Described partly from Calgary material. 

 The types are from Calgary. The ^ is at Washington, and the $ at 

 Rutger's College. A pair marked " Co-type " are in my own collection, 

 but the ^ I have above referred to multilinea. Always common, some- 

 times very abundant. End June to Aug. On one or two mornings 

 during 1902 1 saw moths emptied out of the Calgary arc light globes 

 literally in pints. Quite ninety per cent, of them were this species. It 

 seems to be a close ally oi phragmitidicola, Guen. Under the description 

 Prof. Smith says : '' Comparing two series, their distinctness is obvious ; 

 comparmg selected individuals of each, the sexual characters might have to 

 be resorted to. It is suggestive of a local form that I have wo phragmiti- 

 dicola from the range given for this species, nor any example of this species 

 within the range given for phragniitidicola." Elsewhere he states : 

 '• Anteroc/ara 2i% s. \v\\o\t \% a little larger, a little broader winged, with 

 somewhat less pointed primaries. It is more yellow in colour, less streaky 

 in appearance, the black dot at the end of the median vein often wanting, 

 never prominent, transverse posterior line reduced to two small inter- 

 spaceal dots, and the upper margin of the pale median line not in any 

 way relieved. The secondaries, especially in the 9 , have a smoky 

 appearance, and altogether this seems a duller, more even species than its 

 ally." To the above I would add that the t. p. line is sometimes entirely 



wantmg.
