THE BIOLOGICAL REVIEW. IO5 



proposed names appeared on the list of Canadian insects pub- 

 lished by the Society. In the following year I got six cocoons 

 from Mr. Miller Christy, collected between Carberry and 

 Brandon ; the imagoes which emerged were of the pure Columbia 

 nokomis type. 



In the fall of 1885 I received from Mr. H. Leigh a lot of 

 Columbia cocoons, collected somewhere near Birtle, Manitoba, 

 from twigs of the " Wolf Willow," one of the common names 

 given to E. argentea, but sometimes given also to Shepherdia 

 argentea. Several imagoes emerged, and they were all of the 

 nokomis type. 



In the spring of 1886 I received a small box by mail con- 

 taining three specimens of this moth collected by W. A. 

 Ducker, D.L.S., near Pilot Mound, Southern Manitoba. There 

 were two 9 and one c?' ; one of the 9 had been put in the box 

 alive, and had ovaposited, but so slow had been the transit 

 that the larvae had emerged from the ova, and had died of 

 starvation before reaching me. Although very much rubbed 

 they were evidently of the nokomis type. 



In March, 1887, I received a parcel of galls and cocoons, 

 collected from twigs of the " Wolf Willow " by W. D. Ducker, 

 D.L.S., in the Souris district, and at a point near Moosomin on 

 the line of the C. P. R. These cocoons also gave imagoes of the 

 nokomis type. 



Early in 1894, I received from Mr. E. Heath, of the 

 Hermitage, Cartwright, Man., a package of cocoons of the 

 usual nokomis type, and was informed by that gentleman that 

 the species was not uncommon in his section, and that the larvae 

 feed on the leaves of E. argentea. No imagoes emerged from 

 this lot ; they were all destroyed by parasites. 



It would appear, then, from these records that the nokomis 

 type is generally distributed over the Province of Manitoba, and 

 that the common food plant is Eleagnus argentea, and that 

 probably Shepherdia argentea (Wolf Willow ?) may also be a 

 food plant. I do not know the northern nor the western limit of 

 E. argentea, but Mr. Jas. M. Milne, who was on the Government 

 survey, has informed me that he found the shrub on the eighth
