32 THE CANADIAN ENTOMOLOGIST. 



Museum register, it was collected by George Barnston in Hudson's Bay 

 Territory, the locality, " Albany River, St. Martin's Falls," being enclosed 

 in brackets, but as the entry applies to a number of specimens received in 

 the same lot, it is impossible to be sure of the locality of this particular 

 specimen. The specim.en had been placed with H. argetiteomaculatus. 



I also looked hurriedly over the drawers of North American Colias 

 and saw a number of errors. Interior was in one drawer, while the name 

 Laurentina was put, as originally described by Scudder, as a variety of 

 Philodice, but the specimens under this name were two albino females of 

 Fhilodice, from Philadelphia, a rather narrow-bordered Philodice from New 

 Brunswick and one set under side up. 



Two male specimens of Colias, which, according to the register, were 

 taken in the Rocky Mountains by a collector employed by Lord Derby, 

 about 1845 or 1847, ^"d which, if I am not mistaken, stood in 1897 over 

 a blank label, have now been labeled Astrcea, Edwards, but are certainly 

 not that variety. I may say that I have seen the type of Astrcea, but do 

 not consider it in the least entitled to a varietal name. It is a very 

 ordinary form of Christina, and intergrades with the typical form. I 

 noticed a number of other errors, some of which I pointed out to Mr. 

 Heron, but of which I made no exact notes. 



P. S. — Since writing the above I have received a letter from Sir 

 George Hampson, in which he says : 



" With regard to the specimens standing under rutila, they are 

 exactly as Mr. Butler placed them, as I have not yet come to that part of 

 the subject, and had not in any way studied them till I got your letter. 

 sauzalitce has the frontal prominence very distinct, it is a vertical flat 

 plate, shaped like the letter D, the others have no frontal prominence. 

 rutila has the postmedial line moderately bent outwards below costa, 

 then oblique to vein 6, then inwardly oblique, whilst Harrisii has it 

 strongly bent outwards below costa, then nearly evenly inwardly oblique 

 to inner margin. We have the type and two other specimens of typical 

 rutila, and the three types and two other specimens which I should put 

 under Harrisii, but I am bound to confess that these last two specimens 

 appear to be somewhat intermediate." 



The two specimens regarded by Sir George as intermediate appeared 

 to me to be merely Rutila. 



Mailed January 7th, 190^.
