preliminary list, which will appear in a future number of the Ottawa 

 Naturalist. The large families of Aphididce and Coccidae, which em- 

 brace a large proportion of the species of this order, have not so fiir 

 been much studied and must for the present b_- omitted. The study 

 of some families of the Hymenoptera has been so far advanced that 

 the leaders hope soon to begin the publication of the list of this order 

 which was promised in a previous report; but the printing of which has 

 been postponed, owing to the great number of new species constantly 

 turning up and the difficulties attending their accurate determination. 



Mr. McLaughlin has collected several new species of dragon fl!es, 

 but they are not yet identified. 



In the order Lepidoptera several rare species have been collected. 

 A few specimens of Nisoniades Horatius, not previously recorded from 

 this locality, were taken at Beechwood by Mr. Fletcher, ovipositing on 

 Aquilegia Canadensis. 



A small but interesting collection of moths was taken at the 

 dynamo house of the Electric Light Co. This contamed two speci- 

 mens of Hepialus argenteomaciilatus, Sphinx Kalmitz, SmerintJius 7110- 

 destiis, S geminatus, S. exccecaius and Tolype velleda. Two of the large 

 sphinx caterpillars, Philampelus Achemon and Sphinx Chersis, were 

 injuriously abundant on tlie Experimental Farm, the former on grape 

 vines and the latter on ashes. 



A serious attack on the wheat crop by a small fly {Osdnis vari- 

 abilis) has to be recorded. It is being specially studied by Mr. 

 Fletcher,
