throughout the summer, apparently preferring Virginia creeper but 

 feeding also on grape-vines, honeysuckle, lettuce and other plants. 

 Isa Isabella, S. & A., was observed in normal numbers only, though 

 usually the more abundant of the two species. Pieris {Pontia) rapae, L. , 

 was an unusually abundant pest, especially during August. Danais 

 (Anosia) plexippus (monarch butterfly) was also present in large 

 numbers. Tinea pellionella, L. (clothes-moth) and the large Saturniids, 

 Samia cecropia and Telea polyphemus, were more than usually numerous.

A number of the usual pests of fruits and vegetables are recorded ; 

 no infestation of outstanding importance occurred during the year.

Insects recorded as injurious to field crops included Contarinia 

 (Itonida) tritici (wheat midge), which was abimdant in several localities 

 about mid-July, about 35 per cent, of the grain being shrivelled as a 

 result of the attack in the worst infested fields. Macrosiphum 

 granarimn (grain aphis) was abundant on oats in certain areas. 

 Haplothrips statices, Hal., and Cydia (Laspeyresia) inter stinctana were 

 numerous on alsike and red clover ; Perrisia (Dasyneura) legwninicola 

 (clover seed midge) destroyed as much as 44 per cent, of one crop 

 examined ; Pegomyiafusciceps (seed-corn maggot) was very destructive 

 to beans in Welland Coimty. Fruit pests that were numerous and 

 injurious included Hemerocampa leucostigma (white-marked tussock- 

 moth) on apples, Psylla pyricola (pear psylla) and Rhagoletis pomonella 

 (apple maggot). Miscellaneous insects included Chermes abietis 

 (spruce gall- louse) on Norway spruce, and C. pinicorticis on young 

 white pines.

 antiqua, Mg.) and its Control.— 45fA Ann. Rept. Entom. Soc. 

 Ontario for 1917, Toronto, 1918, pp. 30-33. [Received 16th 

 November 1918.] 



The experiments described in this paper, which supplement a previous 

 bulletin on Hylemyia antiqua, Mg. [see this Review, Ser. A, iv, p. 347], 

 have already been recorded from another source [see this Revieiv, 

 Ser. A, vi, p. 122]. Observations during the year have confirmed 

 the supposition that this fly hibernates in the pupal stage in Canada.
