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 

 like the Apple Maggot it is abundant in some seasons in the State of Maine close to our 

 borders. 



TuE Native Currant Saw-fly. {Gymnonychus appendiculatus, Hartig). — This 



insect which was formerly called Pristiphora 

 grossularice, Walsh, is by no means common 

 in Canada, but last spring the larvae did con- 

 siderable damage on Vancouver Island. The 

 Rev. G. W. Taylor wrote from 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 

 year. A second brood appeared at the middle 

 of June, but the larvae were much less nume- 

 Fig. 13 — The Native Currant Saw-fly — larva rous." Several specimens of the mature insects 

 and adult. 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 careful examination of 

 the sawflies received by you from Rev. G. W. Taylor, and find them to be Gymnonychus 

 appendiculatus, Hartig. On my first examination the insects were referred xo 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, II., p. 66) the description of Nematus 

 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 {Ifematince of N. A., p. 122) for those species 

 of Pristiphora having the claws entirely untoothed igtcmnos = 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. grossularice, and treated of under that name by Walsh, Packard, Glover, 

 Riley, Saunders and other writers (see Marlatt, loc. cit.). Norton's P. relativa may pos- 

 sibly be identical. — [W. H. Harrington.] 



THE SAN JOSE SCALE 

 (Aspidiotus perniciosus, Comstock). 



"Well, how about this San Jos^ 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 Jos^ Scale were received 

 for examination from orchards near Chatha«a, 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 i^rowers 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 tlie same year, and the 

 Farmers' Advocate of London, Ont., an influential agricultural journal with an extensive
