found in May and June, spin the edges of young leaves together in 

 which they live for some time ; later they may be seen among the 

 shoots feeding on the foliage. They pupate amongst the twisted 

 leaves and the adults may be seen on the wing from the end of June 

 to July. Remedial measures advocated are hand-picking and spraying 

 with lead arsenate.

Attention is drawn to the occurrence of Hylemyia antiqua {Antho- 

 myia ceparum) at the base of leek seedlings of the Champion and 

 National varieties, whilst Musselburgh leeks were untouched.

The thripe here recorded include Orothrips kelloggi yosemitii, Moult., 

 on Amelanchier in July; Aeohthrips fasciatus, L., on Lithospermum 

 pilosum, Elymus condensatus, clover, Crataegus, cherry, Prunus 

 demissa and Amelanchier, during May, June and July, and also found 

 in association with Thrips tabaci (onion thrips) on which it is probably 

 predaceous. It is recorded as predaceous on Kakothrips pisivortts, 

 Westw., in Europe, although it also feeds on the pollen and juices 

 of plants. Aeohthrips annectans. Hood, has been taken during May, 

 June and July on a variety of plants, including Acer glahrum, Ribes 

 viscosissimum, Sambucus racemosa, Ilex europaeus, apple, alder, 

 Lithospermum pilosum and Amelanchier florida. It is associated with, 

 and probably predaceous on Thrips tabaci. Aeohthrips auricestus, 

 sp. n., was found on western wild rye grass {Elymus condensatus). 

 Taeniothrips inconsequens, Uzel (pear thrips) is also described, and 

 other species mentioned are : Thrips physapus, L., on dandelion in 

 April and May and Rubus parviflorus during June ; Thrips tabaci, 

 Lind. (onion thrips), of which the larvae of the first generation appear 

 early in June ; Haphthrips statices, Hal,, found on apple, plum. Spiraea 

 discolor and other native shrubs, and possibly also injuring red clover ; 

 Leptothrips mali, Fitch, taken during May, June and July from the 

 foHage and branches of Acer glabrum, alder, Amelanchier, apple, 

 peach and Crataegus ; and Chirothrips manicatus, Hal., on many 

 roadside grasses.

 lionidae). — Canadian Entomologist, London, Ont., li, no. 8-9, 

 Augus1>-September 1919, pp. 199-201, 1 plate, 1 fig. 



Pelenomus sulcicollis, Fhs., of which all stages are described, was 

 foimd in large numbers infesting fringed loosestrife {Steironema 

 ciliatum) in New York State. The eggs are laid singly beneath the 

 lower epidermis of the leaves near the veins as a result of which that 

 area dies and becomes brown. The larvae feed on the lower surface 

 of the leaves and when mature spin a small cocoon on the imder 

 surface or axil of the leaf, in which they pupate. The weevils emerge
