PRELIMINARY LIST OF THE MACRO-LEPIDOPTERA OF 

 ! ALBERTA, N.-W. T. 



BY F. H. WOLLEY DOD, IMILLARVILLE, ALTA., N -^V. T. 



(Continued from Vol. XXXVL, p. 355.) 



150. Hadena (Xylophasia) remissa, Hbn. — Nine ^ $ ^i light in 

 1903, and a few of both sexes at light and treacle during 1904. Not 

 previously met with. July 15th tcr Aug. 2nd. Prof. Smith says they are 

 " somewhat paler in ground colour than New England examples." In a 

 general way the species resembles a pale ferens, with which species Mr. 

 Hudson and I at first confused it whilst collecting. 



151. H. (X.) sufusca, Morr. — Fairly common at treacle. End June 

 and July. 



152. H. (X.) rorulenta, Smith. — (Psyche, June, 1904, p. 55). De- 

 scribed partly from Calgary material. Allied to and contemporaneous with 

 suffusca, but less common. I had the forms standing in two series in my 

 collection for some years, and there always seemed to be a sharp contrast 

 between them, nothing intermediate ever turning up. Prof. Smith does 

 not state whether he compared the type of suffusca when naming this 

 species, but says : " 1 have separated out as suffusca those examples 

 in which the ground colour is of an even lilac-gray, the reddish 

 suffusion is uniform, and neither the ordinary spots nor the terminal 

 space contrast strongly. In the new species either the reniform or 

 terminal space, or both, contrast strongly, and are violet or lilac gray. 

 The s. t. line is more sharply defined, the preceding marks blackish and 

 more contrasting, as well as more numerous. The lower half of the wing 

 tends to a gray, which is best marked on the inner margin. The upper 

 half of the wing is reddish, pulverulent, and is darkest on the costa." I 

 would add that the ground colour of the newly-named form is of a reddish 

 ochreous, much like the pale ground of vultuosa, and that the reddish 

 shading in upper half of wing contrasts strongly, and is much more con- 

 spicuous than it is against the dark lilac-gray ground of suffusca. Prof. 

 Smith has specimens also from Winnipeg, Denver, Colo., and New York 

 State, so the two species, if such they really are, would seem to have much 

 the same range, and are probably mixed in many collections. The type 

 is at Rutgers College, and a perfect pair of co-types are in my own 

 collection. 



153. H. (X.) vultuosa, Grt. — Rather rare. End June and July. 



; 154. J5^ (X.) contradicta, Smith. — Generally very rare. Described 



January ,1905.
