•THE CANADIAN ENTOMOLOGIST. 257 



Early July to middle Aug. A very variable species. I am not aware 

 that I have taken more than one female. 



510. E. Ha?ihami^ Hulst. — Fairly common in the hills, but I have 

 not so far met with it on the Red Deer prairies, where most of the other 

 " waves " occur. Middle June to middle July. Described from Winni- 

 peg. " Closely allied to ^linearia and persimilis, but with much more 

 rounded wings, and the two outer lines different in direction." It is a 

 whiter species than my ^-linearia, and beneath it is far more smoky, 

 lacking the -conspicuous yellowish costa of that species. It also differs 

 considerably in wing form. I have compared Kaslo specimens of the 

 species recorded by Dr. Dyar in the Kootenai list as rotiindopennata. 

 Pack., for which I am indebted to IMr. Cockle, and am unable to 

 distinguish them from this species. 



511. Arifiemoria bistriaria. Pack.— A male at light at the Red 

 Deer River locality, on July 5th, 1905. 



512. Eucrostis viridij)e?inata, Hulst. — Rather common some 

 years. Middle May and June. Mouth of Fish Creek and head of Pine 

 Creek. Fresh specimens are of a beautiful dark emerald, but it is the 

 most fleeting green I know. It soon fades in life, and it is quite impos- 

 sible to relax a good specimen without its turning to a dirty yellowish 

 green or brownish yellow. If set fresh it keeps its colour fairly well. It 

 was described from Colorado, but Hulst had a Calgary specimen from 

 me, and called it viridipetinata more than a year before the description 

 was published. I obtained ova in 1905, and find a note that they hatched 

 on June 2nd, and that the larva fed on Salix. They produced moths the 

 following spring, but none were i)reserved. A day flier. 



513. Syfichlora glaucaria, Gn., = aerata, Fabr. — Not common. 

 Head of Pine Creek, end June and July. I have not seen it elsewhere. 

 Weather bleaches it from green to pale luteous, but the colour is not as 

 fleeting as in the preceding species, nor does relaxing injure it. A 

 specimen that Mr. Taylor has from me differs, he tells me, from all other 

 described species of the genus in having a considerable portion of the 

 usual green on secondaries replaced by white. None of my other speci- 

 mens, however, show this variation. 



514. Aplodes Hudsonaria, Taylor (Can. Ent., XXXVIII., 206, 

 June, 1906). — Seven males, at dusk and light, on the Red Deer 

 River, north-east of Gleichen, whence the species was described, 

 and named after Mr. Arthur F. Hudson, its first and prmcipal
