14 THE REPOET OF THE No. 36 



into the soft flesh of apples in autumn to hibernate is shown in figure 1. In one 

 apple examined in September last two larvae were found. The holes where the 

 larvae had entered were conspicuous. Several apples were examined and, in one, 

 three holes occurred close together. An examination of these indicated that the 

 larva evidently has the habit of boring several holes before finally closing one up 

 in which to pass the winter. In one case the cavity in the apple was five-eighths 

 of an inch long by one-eighth of an inch wide. The end was closed up with the 

 " chewings " made by the larva, no f rass being present. In another instance the 

 larva had entered to a distance of nine-sixteenths of an inch and in still another 

 eleven-sixteenths of an inch. In every case the head of the larva was towards the 

 skin or outside of the apple. The larva was one-half inch in length, dark green 

 in colour, the sides and centre whitish green; head pale brown, darker brown at 

 vertex, on either side a conspicuous dark brown spot. In the December, 1915, 

 number of the Proceedings of the Entomological Society of Washington, Eohwer 

 places the name we knew the insect by, viz., Taxoniis nigrisoma Nort., as a synonym 

 of the European species, Ametastegia glabrata (Fallen). 



Greenhouse and Gakden Plants. 



Garden plants of many kinds suffered seriously from the attacks of plant lice, 

 and in early spring newly set out annuals were cut off by cutworms, the Striped 

 Cutworm being the most destructive of the species which occurred in 1915, 



The Four-lined Leaf Bug {Pcecilocapsus Uneatus Fab.) was abundant in 

 the district, attacking freely such garden plants as asters, dahlias, etc. 



The Eed-headei^ Flea Beetle (Systena frontalis). As already mentioned, 

 this common flea-beetle was found this year in August attacking asters and 

 chrysanthemums. 



The most interesting greenhouse insect of the year at Ottawa was the oc- 

 currence of the Chrysanthemum Midge, (Diarthronomyia liypogcm H.Lw.) in one 

 of the large houses. This insect had doubtless been recently introduced with the 

 plants from the United States, where it has become recently established. The 

 Ottawa occurrence is the only record we have of the midge in Canada. Dr. Felt,* 

 the ISTew York State Entomologist, in writing of the. species in April, 1915, recom- 

 mends the destruction of badly infested plants by burning. Where the leaves only 

 show slight infestation many of these may be removed. Fumigation with hydro- 

 cyanic acid gas would, of course, destroy the midges but would have little or no 

 effect on the larvae, which work within the leaf tissues. 



Division No. 3, Toronto District — A. Cosens. 



So far as the writer is concerned, the Entomological season of 1915 opened 

 April 7th with a trip to the Etobicoke, a small stream that enters Lake Ontario 

 a few miles west of the city. The banks of this creek are still wooded in many 

 places, and even yet the Indian significance of the name, " the place of the Alder," 

 is peculiarly applicable. The locality was choice, hut a delightfully warm sun 

 and the lethargy incident to the first tramp of the year made energetic collecting 

 almost an impossibility. This and the early date serve as an explanation of the 

 confession that the only insects captured were specimens of Aphodius femoralis 

 Say., many of which were on the wing. 



The excessive rainfall and the low average temperature of the past summer 

 do not appear to have reduced materially the production of the various forms
