 Haltica chalybea (grape flea-beetle), Monophadniis (Monophadnoides)

 aphid). Field crops were attacked by Macrosiphimi pisi (pea aphis), 

 Cirphis unipuncta, Crioceris asparagi, C. 12-puncta(a, Anasa tristis 

 (squash bug), Diabrotica vittata (cucumber beetle), Leptinotarsa decem- 

 lineata (potato beetle) and Pieris rapae. Black walnut trees were in 

 some cases almost defoliated by Datana integerrima, and the larvae of 

 D. ministra were found on American elm and basswood trees. Scotch 

 elms were attacked by Eriosoma {Schizoneura) ulmi and Tetraneura 

 vJmisacculi. Cyllene robiniae (locust borer) was very abundant during

Tent caterpillars \Malacosoma, sp.] were very abundant over the 

 entire province. Some of the pupae were attacked by a Hymenop- 

 terous parasite. Late in September, Datana ministra (yellow-necked 

 apple-tree caterpillar) was found defohating basswood trees. The 

 larvae of Pieris (Pontia) rapae were common wherever cabbages were 

 grown. Outbreaks of Cirphis {Leucania) unipuncta (army-worm) 

 were reported from two localities. Eucosma (Tmetocera) ocellana (bud- 

 moth) was prevalent in apple orchards and Rhagoletis pomoneUa was 

 abundant in several locahties. Lepidosaphes idmi (oyster-shell scale) 

 was found on the fruits of apple and plum and terrapin scale [Eulecanium 

 nigrofasciatuni] on Prunus americana and on the butternut. Typhlo- 

 cyba comes (grape leaf-hopper) was recorded from three localities. 

 Eriosoma lanigerum was prevalent in wounds and under cankered 

 areas ; the winged form was captured in large numbers by tanglefoot 

 bands. Ceresa bubalus (buffalo tree-hopper) caused serious injury to 

 young apple trees. Potatoes were attacked by flea-beetles and Colorado 

 potato beetles. Chrysobothris femorata (flat-headed apple-tree borer), 

 AntJwnomus quadrigibbus (apple curculio), Conotrachelus nenuphar 

 (plum curculio) and Anthrenus scrophulariae (buffalo carpet beetle)

The outbreak of Cirphis unipwuta in Ontario was first reported on 

 14th July in Brant County. Later reports showed that the pest was 

 generally distributed throughout Old Ontario, with the exception 

 of the eastern counties. An account of the life-history and feeding 

 habits is given. The following parasites 'were reared from this pest 

 during 1914 :• — Tachinidae : Phorocera (Euphorocera) claripennis, 

 Wagneria [Phorichaeta) sequax, Winthemia qiiadripustulata ; Ichneu- 

 MONIDAE : Ichneumon canadensis, I. jucundus, Paniscus geminatus,
