DIPTERA. 

 By W. Hague Harrington, Ottawa. 



Scant attention is given to the members of this order by our collectors, and no papers 

 have been published recently regarding our flies except that of Mr. Chagnon upon the Syrphidae 

 of the Province of Quebec which first appeared in the Naturaliste Canadien for 1901, but 

 is now issued as a pamphlet of 75 pages in which he describes 33 genera and 71 species. Mr. 

 Chagnon seems to be the only Canadian collector specially studying diptera. A few are taken 

 occasionally by other members, but in most collections these insects are probably unnamed. 

 Lists have been received from Mr. Harvey, of Vancouver, and Mr. Mcintosh, of St. John, N. 

 B. These will be reported at a latter date. Dr. Schmitt, of Anticosti Island, has forwarded 

 some from that unworked locality, but many of the species have yet to be determined. Since 

 the discovery of the carrying of fever germs by mosquitoes, special attention has been directed 

 to these forms in America and elsewhere, and many new species have been described, and 

 much has been learned of the larval habits of different species which was formerly unknown. 

 The wave of investigation has however been but slightly felt in Canada. 



The following eleven species of diptera have been added to our fauna at intervals ; 



Sciophila subccerulea, Coq. n. sp. Proc. U.S. Nat. Mus. Vol. xxiii, p. 595 — Canada, New 

 Hampshire and Pennsylvania. Ottawa (Harrington).

 ( Harrington).

 boia (Fletcher). 



Simulium fulvuni, Coq. n. sp. Proc. U.S. Nat. Mus., Vol. xxv, p. 96 — Montana, Colo- 

 rado, Alaska and British Columbia. Calgary, Medicine Hat, N. W. T. and Mt. Cheam, B. C. 

 (Fletcher). Laggan, B. C. (Wickham).

 Canada. Rouville, Q. (Chagnon). 



Tephronota Canadensis, Johnson, n. sp. Ent. News. Vol. xiii, p. 144 — Rigaud, Que. 

 (Chagnon). 



Fsilocephala grand is, .Johnson, n. sp. Can. Ent. Vol. xxxiv,p. 241 — Rouville, Que. (Chagnon). 



Pyrgota Chagnoni, Johnson, n. sp. Can. Ent. Vol. xxxii, p. 246— Montreal. (Chagnon). 



Tipuladccora, Doane, n. sp. Journ. N.Y. Ent. Soc. Vol. ix, p. 125 — Montreal (Chagnon). 



Mr. Chagnon writes : My most important capture among the Syrphidae is a specimen of 

 Merodon eqiiestris, Fab. This is new to North America and is an interesting addition to our 

 fauna. Mr. Mcintosh has also added many new species to the Canadian list, all of which have 

 passed through Mr. Coquillett's hands. 



fe A KEY TO ORCHARD INSECTS. 



^^k- By W. Lochhead, Ontario Agricultural College, Guelph. 



^^^ Signs are not wanting that our fruit growers desire more definite information about the 

 insects commonly met with in the orchards. They want to kn(ho the insects which they are 

 constantly fighting. They want to spray intelligently and with a definite purpose in view, and 

 not by a blind rtde-of -thumb, as set forth in some spray calendar.
