primaries. Add to this a distinct difference in the genitalia of the male, 

 and the specific separation proves inevitable." If the specimen was 

 placed with the Chicago and east coast series, and all labels removed, I 

 defy any man to pick it out, without recourse to the genitalia, by any one 

 of the characters mentioned. The type of tertialis is in Prof. Smith's 

 collection at Rutger's College. 



332. Leucania unipujicta, Haw. — Rare on the whole. Apparently a 

 migrant. Worn specimens end of June and July, fresh specimens in 

 October. Treacle. 



333. L. minor ata, Smith. — Not rare. July to middle Aug. The 

 name is the one given me to the species by Prof. Smith. The species was 

 described from three ^ ^ from California and Oregon, which were said to 

 resemble oxygale, Grt. " But are smaller throughout, the ground colour 

 reddish, the secondaries darker." The only locality given for oxygale in 

 either Dr. Dyar's List or Prof. Smith's Catalogue is Colorado, so I presume 

 it was described from there. In the Revision of the genus, however 

 (Proc. U. S. Nat. Mus., Vol. XXV., pages 159-209, 1902), both in the 

 table on page 164 and under the descriptions, Prof. Smith distinctly treats 

 of oxygale as having the darker secondaries of the two. He there 

 describes luteopallens from Canada and the eastern States as distinct from 

 both in being paler throughout, and claims that all three are separable 

 from European paliens, citing tninorata as its American representative. 

 Dr. Dyar in his Kootenai List records oxygale as common at Kaslo, and 

 refers all four names to one species, treating oxygale and luteopallens as 

 geographical races of pallens, and ininorata as a varietal and not racial 

 form of oxygale. I have a good series of luteopallens from several places 

 in the east, and specimens exactly like the Calgary form from Victoria, B. 

 C, and Manitoba, and a Kaslo series from Dr. Dyar also inseparable from 

 it. As a whole my eastern specimens are certainly paler and less streaky 

 throughout, and have less black on secondaries than the western speci- 

 mens, but the extremes overlap. The type of minorata is at Washington, 

 and is figured with the description. 



334. Z. albilinea, Hubn. — Four ^ $ only, June 30th to July 21st, 

 in three different years. They have the secondaries dark smoky through- 

 out, scarcely or not at all paler at the base. At light. 



335. L. diffusa, Walk. — Very rare. I have seven ^ ^ only. May 

 20th to July 22nd. Light. The primaries are paler in colour than the 

 preceding, and secondaries smoky in outer half only. I had the two 

 mixed until about a year ago, but a close examination brought me to
