THE CANADIAN ENTOMOLOGIST. 53 



tells me that the larvi« were very dark brown, with rather short hairs, and 

 that they pupated in the spring after hibernation. He reports the larvae 

 as having been almost abundant during 1903, but says that he failed in 

 an attempt to hibernate some of them. 



446. Notolopluis antiqua, Lin. — Very rarely met with, indeed. I 

 have only two records, both males. One was taken by myself near the 

 mouth of Fish Creek in 1893, and the other by Mr. Hudson, head of Pine 

 Creek, at rest on a binder, Sept. 3rd, 1903. I have not infrequently 

 found empty cocoons, sometimes with hatched ova on them, on trunks of 

 Populus tremiiloides, which I believe to have been those of this species. 



447. Oiene plagiata, Walk. — Two tine males. One taken by Mr. 

 Hudson in 1903, labelled (? July 27th), probably at light : the other July 

 9th, 1904, at light. 



448. Mdlacosoma Americana, Harr. — A single 9 , bred on xA.ug. 

 6th, 1905, from a larva taken on the Red Deer River, north east of 

 Gleichen. A large number of larvae were collected there during the first 

 week in July by ]\Ir. Hudson and myself, as they appeared obviously to 

 differ from those we were so used to seeing in the Pine Creek district. 

 Owing to an accident only one was brought to maturity. They were 

 found commonly feeding on rose, saskatoon and wolf-willow, but I cannot 

 recollect that we found them on true willow ( Salix). They differed from 

 the larva of the following species in the predominance of pale gray mark- 

 ings, especially in the lateral area, at the expense of black and yellow. I 

 refer the species here, though with some doubt, owing to the resemblance 

 of the specimen bred to a series kindly sent me under the name from 

 Toronto by Mr. Gibson. , 



449. Af./ragiiis, Stretch. — The name was first given me by Prof 

 Smith, and Dr. Barnes has seen my series and not questioned its correct- 

 ness. I cannot state positively that I have not more than one species in 

 the series, but can draw no line. The males are normally darker than the 

 females, and vary from pale luteous (? var. constrictifia, Neum. and Dyar) 

 to dark red-brown, with luteous transverse lines. The central band is 

 nearly always darker, especially in luteous specimens, and the edges of the 

 band usually darker than the centre. Thus, in luteous specimens the dark 

 edges show up as lines when tiie luteous lines are dissolved in the pale 

 ground. The lines are generally even. I must admit that I have speci- 

 mens which I can hardly separate from some of my Ontario series of 



Americana, which seem to differ mainly in being browner, with less of the 

 reddish tinge. The females show similar variation to the males, but run
