REPORT OF THE ENTOMOLOGIST AND BOTANIST. 205 
notwithstanding its name Canadensis, I had never before seen in Canada, nor have I 
heard of its injuries in any other part of the Dominion than British Columbia. 
In a very complete monograph upon this insect, published in 1896, by Prof. F. L. 
Harvey, of Maine, full details are given of the life history and habits. With the excep- 
tion of British Columbia, this insect is certainly nowhere common in Canada, although 
an he Apple Maggot it is abundant in some seasons in the State of Maine close to our 
orders. 
Tue Narive Currant Saw-Fty. (Gymnonychus appendiculatus, Hartig).—This 
insect which was formerly called Pristiphora 
grossularie, Walsh, is by no means common 
in Canada, but last spring the larve did con- 
siderable damage on Vancouver Island. The 
Rev. G. W. Taylor wrote fron Gabriola Island, 
B.C., on July 29 last :—“ The saw-flies of the 
gooseberry and currant appeared early this 
season and practically spoiled the bushes for the 
mas year. A second brood appeared at the middle 
of June, but the larve were much less nume- 
Pig. 13—The Native Currant Saw-fly—larva ous.” Several specimens of the mature insects 
a etule were bred by Mr. Taylor and forwarded for ex- 
_ amination. These were submitted to Mr. W. H. Harrington, who has made a special 
study of this class of insects and he has kindly provided me with the following report 
upon them :— 
“Gymnonychus appendiculatus, Hartig—I have made a carefui examination of 
the sawtlies received by you from Rev. G. W. Taylor, and find them to be Gymnonychus 
appendiculatus, Hartig. On my first examination the insects were referred to the genus 
Pristiphora, and seemed to answer very closely to Norton’s description of his P. relativa, 
the type of which was from Great Slave Lake, collected by R. Kennicott. On reference 
to Cameron (Brit. Phytophagous Hymenoptera, I1., p. 66) the description of Vematus 
appendiculatus was found to apply very closely to the Vancouver Island specimens, and 
a microscopical examination of the claws shows that the species belongs to the new 
genus Gymnonychus erected by Marlatt (Wematine of N. A., p. 122) for those species 
of Pristiphora having the claws entirely untoothed (gwmnos = naked, and onux = a claw). 
The species, therefore, is now named as above cited and is the currant saw-fly named by 
Walsh as P. grossularie, and treated of under that name by Walsh, Packard, Glover, 
Riley, Saunders and other writers (see Marlatt, Joc. cit.). Norton’s 2. relativa may pos- 
sibly be identical—| W. H. Harrington. | 
THE SAN JOSE SCALE 
(Aspidiotus perniciosus, Comstock). 
“Well, how about this San José Scale we hear so much about?” is a trite question 
which has been very frequently put to the Entomologist during the past season. 
Early in the present year undoubted specimens of the San José Scale were received 
for examination from orchards near Chatham, Kent Co., and from near Niagara, Lincoln 
Co., in western Ontario. 
In 1894, in anticipation of the spread of this most injurious pest of the orchard 
from infested States to the south of us, and so that our fruit growers might be warned 
beforehand, articles were prepared and published in the report of this Division, the 
Annual Report of the Entomological Society of Ontario for the same year, and the 
Farmers’ Advocate of London, Ont., an influential agricultural journal with an extensive
