median and t. )). lines seem more sharply Junulate inwards and toothed 

 outwards than in tri/o/ii, the s. t. line and terminal shade are hardly 

 discernible, and the secondaries lack the pearly sheen of that species. By 

 the hairy eyes it is certainly Mameslra rather than Scotogramma, but it 

 was its dark luteous tint and smoky suffused maculation which made me 

 place it tentatively with//;^m. Prof. Smith has recently seen the specimen 

 and, calling it tri/olii, adds, " I can't say anything else, unless you prefer 

 to label it Oregonica. In my series the primaries become almost black.'' 

 It stands waiting for something like a connecting link. Dr. Dyar in 

 recording a specimen of Oregonica in Mr. Cockle's collection at Kaslo, 

 adds, "I am inclined to regard this form as distinct from trifolii" 

 ( Kootenai list). 



300. J/, obesula. Smith. — (Can. Ent., XXXVI, 151, June, 1904). 

 Described from a ^ and three $ 9 : one from Denver, Colo., the rest 

 from here. The lyi)e is in Prof. Smith's collection at Rutgers College. 

 Two pair, one a 9 co-type, are in my own. Six specimens altogether 

 have been taken, all at light^ July 20th to i\ug. 5tli, 1903. The descrip- 

 tion says, " It is in a way intermediate between Farnhami and trifolii, 

 having the colour contrasts of the former, with the build and maculation 

 of the latter." I endorse those remarks, though before the description 

 was published I had not noticed its resemblance to Farnhami, and had 

 placed it next irifo/ii, than which, as its name implies, it is a stouter, 

 heavier built insect, broader winged, and with less acute apices. It seems 

 to be a well-marked species. 



301. M. rosea, Harr. — Common. End May to early July. 



302. Af. rubefacta, Morr. — Very rare. Four or five specimens only. 

 Middle June and early July. 



303. M. picta, Harris. — A single specimen, ^J , on Aug. i6th, 1903, 

 by Mr. Hudson. It is slightly smaller, but otherwise not separable from 

 Chicago examples. 



304. M. assimi/is, Morr. — Not met with previous to 1896, when a 

 few were taken. Since 1901 it has been rather common. End June and 



305. /)/. ingravis. Smith. — Described from Calgary, and figured with 

 the description. Fairly common at treacle and light, May and June. 

 From what Prof. Smith says, this seems to have no very near allies in the 

 genus. Some specimens show a decided tendency to melanism. The 

 type is at Washington.
