iSgy.] Report of Entomological Branch. 15 



recent Bulletin (No. 7, New Series) of the Division of Entomo- 

 logy of the U' S. Dept. of Agric. The author, Mr. L. O. How- 

 ard, under the title " A Case of Excessive Parasitism," relates 

 the fate of some scale-insects, Lecanium fletcJieri QocV&x€\\, which 

 had been obtained in June upon one of the cedar hedges at the 

 Ottawa Experimental Earm. From 80 scales there were obtained 

 127 parasites ; others, however, had previously issued so that 

 97-| per cent, of the scales were infested. Six species of intruders 

 werere presented, viz. : — Coccophagus co^jiatus How., C.fletcJieri 

 n. sp. , Aphycus piilvinaria Hew., ^'//.//'/jii- flavus How., Cliilo- 

 neurns albicornis How., and Blastothrix longipennis How. Other 

 scale-insects, such as the Elm Lecanium, have also been found 

 very much infested by similar tiny foes, by which the balance of 

 Nature is kept finely adjusted, and the spread of the very in- 

 jurious scales is rapidly checked. A very interesting little 

 Braconid has again been rared from pupariaof asmall fly named 

 Pkytomysa geanidis Loew. The larvae of this fly are miners in 

 the leaves of our common Columbine (Aquilegia Canadensis) 

 and much disfigure them by causing large white irregular streaks 

 and blotches. Mr. Anhmead, who found the parasite to be un- 

 described has named it Mesora phi/tomyza and will publish its 

 description in his forthcoming monograph of the Braconidse. 



Mlscellaneou.S. — In other orders little or no work, at least 

 of a systematic nature, has been done, but the Leaders have en- 

 deavoured to make arrangements by which these, at present, 

 neglected groups may receive more attention and may have the 

 species belonging to them gradually collected and determined. 

 This must be done. if the Club desires to fulfill the object for 

 which it was specially organised, viz., the accumulation and 

 publication of a full knowledge of the geology, flora and fauna 

 of the district. 



Injurious insects in the Ottawa district were not particularly 

 noticeable during last year. Cabbage and radish maggots were
