. Annual report. Entomological Society of Ontario; Insect pests; Insects -- Ontario Periodicals. Ffg. 46.—Sarcophaga earraceniaj.. Fig. 47.—A Muscid Fly. Among the Ortalidse is found that most remarkable and handsome fly, Pergata undata, Wied., which is figured on page 610 of "Insects Injurious to Vegetation" by Harris. I have taken several specimens of this fine fly in the Eastern Townships. Another beautiful insect belonging to this family is Chcetopsis oenea, Wied. It has a glossy blue body, and pretty banded wings. I have found its maggots preying upon Lepidopterous larvae, in the stems of bulrushes, and have raised the perfect insects from them. Of insects in the family Trypetidse I have taken at Quebec, Straussia longipennis, Wied., Eutreta sparsa, Wied., Eurosta solidaginis, Fitch, and Tephritis alhiceps, Loew. It is Eurosta solidaginis that inhabits the large, round pithy galls that are found on the Golden Rod. In the Piophilidae comes the well known Piophila casei, Linn., whose larvae are the "hoppers" found in cheese. There are some other families of Diptera to which it does not come within my present purpose to refer. I have endeavored to compress within the limits of this article such information as seemed to me likely to arouse an interest in the two winged flies, and to convey ideas of their number, variety and habits. Everj^ species has doubtless its peculiar life-history —known or unknown, to man. Every species fulfils its purpose in the economy of Nature. They all bear testimony to the marvellous resources of the Divine Creator, who in Wisdom hath made them all..
