outwardly than in his figure, and arc scarcely darker than in some of my 

 ptcrptirissata. 



287. M. colianbia, Smith. — Originally described as a Tceniocampa, 

 but referred by its describer to this genus in Trans. Am. Ent. Soc, XXIX., 

 199 (June, 1903). The types are in the Museum of the Brooklyn Institute 

 of Arts and Sciences and in U. S. National Museum, and were taken by 

 Capt. Geddes in 1884 in "North-west British Columbia." The locality 

 thus vaguely recorded may in this instance be intended for Alberta, 

 N.-W. T., where Capt. Geddes seems to have done a good deal of collecting, 

 and where the species is rather common at treacle, and sometimes on 

 flowers in the daytime, during July and August. Some years ago Prof. 

 Smith named the species for me as mcditata, under which name I suspect 

 that it still stands in many collections, and of which it is, I suppose, the 

 Western representative. I have compared a good series of both sexes from 

 Calgary vvith 2 ^ ^ and a ^ from CarLwright, Man., and with a series of 

 meditata from Chicago and the extreme North-eastern States. The U. S. 

 specimens run much darker in colour than our Western form, being dark 

 reddish-brown, sprinkled with gray scales, Columbia, as a rule, varying from 

 a pale rusty yellow to an almost pinkish red. The three Manitoba speci- 

 mens, however, which come from Cartwright, from Mr. Heath, though 

 certainly Columbia, rather than meditata, seem to suggest an intergrade. 



288. M. cervina. Smith. — Described from Winnipeg, Man. The type 

 is at Washington. Formerly confused with lustralis, under which name I 

 used to send it out. The description states, "It is a narrower vvmged 

 species, coming nearer to meditata in this respect and with less well pecti- 

 nated antennte. The markings, while much the same in all essential points, 

 are less distinct." There also seems to be a difference in the genitalia. I 

 have only one $ lusti-alis, coming from Dr. Barnes, locality not stated. 

 Besides being paler, it differs in the points mentioned, except that I can 

 see no antennal difference, even with a lens. Not rare. End June and 

 July. Dr. Holland's figure oi lustralis is legitima, Grt. 



289. M. segregata. Smith. — Described from Laggan (B. C. in error). 

 Taken at light, May 13th and 17th (T. E. Bean). Figured with the de- 

 scription. 



290. M. gussata, Smith. — ) Not rare at Sallow blossoms near mouth 



291. Jlf. negussa, Smith. — j of Fish Creek, Bow River, at end of 

 April and early May. Both described from Calgary. Both are figured 

 with the description, and a good figure of negussa is shown in Dr. Holland's
