120 THE CANADIAN ENTOMOLOGIST. 



America this species is considered as synonymous with A.freya, Thunb. 

 With us it occurs from Alaska to Labrador and westward to the Rocky 

 Mountains, which range it follows southward to Colorado, about lat. 39°. It 

 is probable that in southern Norway it is also confined to the mountain 

 regions, 



*A. frigga, Thbg. Dr. Schoyen's list restricts this to four provinces— 

 Akershus, Buskerud, Tromso and Finmarken. The first two are northern 

 coastal, the last two southern inland. The range is from 59° 56' to 

 70° 40'. With us it is recorded as inhabiting Arctic America and 

 Labrador, and from Alaska south along the Rocky Mountains to 

 Colorado. 



Erebia disa, Thbg. This is recorded as inhabiting but two pro- 

 vinces, Finmarken and Nordland, the former the northernmost and 

 the latter in the central portion of the country, the two being separated 

 by the province of Tromso. The range is limited to from 66° 50' to 70°. 

 In America, we have the variety mancitnis, Db-Hew, which appears to be 

 quite common in northern Alaska, whence it extends to the Rocky 

 Mountains in British America, with the southern limit not yet defined. 



The idea of giving the latitude of the occurrence of species is, it 

 appears to me, much better than giving the name of some out-of-the-way 

 place that is not included on even a small portion of our own maps, to 

 say nothing of those to which entomologists of other countries have 

 access. The name of the place is all well enough, but where the latitude 

 can also be given it will render the statement as to location much more 

 intelligible, both at home and abroad, and this too despite any variation 

 in the matter of isothermal lines. 



TRYPETA SOLIDAGINIS, FITCH, AND ITS PARASITES. 



BY REV. THOMAS W. FYLES, SOUTH QUEBEC. 



In April of last year I found on the banks of the Ottawa River, at 

 Como, Province of Quebec, a number of very fine stems of a species of 

 Golden-rod. These stems v/ere bare and dry, and bleached by the winter 

 storms. Their attraction for me lay in this — nearly every one of them 

 was burdened with a fine large Trypeta-gall, On some of them two such 

 galls were to be seen, I measured one of the excrescences, and found it 

 to be three inches and five-eighths of an inch in circumference. The 

 galls of the same kind that I have found at Quebec have not been nearly
