Lygus camjpestris, L., is widely distributed in North America, and is 

 common in Nova Scotia. It has been recorded from Europe and 

 America on Umbelliferae, and in New York on the poison hemlock 

 {Conimn maculatum). At Truro, Nova Scotia, it has been found on 

 wild parsnip [Heracleum lanatum) and the cultivated parsnip {Pastinaea 

 saliva). The adults first appear in late June and throughout July, 

 and oviposition begins about a week after emergence, the eggs generally 

 being laid in the grooves of the small stalks bearing the flower-heads. 

 Hatching occurs within a few days and the nymphal stage lasts between 

 four and five weeks, during which five moults occur. The adults, 

 after a short period of activity, seek a suitable shelter for winter 

 quarters, where they remain until the following spring. Details of 

 the life-history are given in a table and the various stages are described. 



The injury to the plant is of two kinds, the oviposition punctures 

 on the small stalks bearing the umbels causing the flower-heads to 

 droop, and secondly there is the damage resulting from the feeding 

 punctures of both adults and nymphs, both on the flower-heads and 

 on various other parts of the plant, including the kaf-petioles. In several 

 cases the death of the plants may be caused in this way. While the 

 insect is capable of doing considerable damage under certain con- 

 ditions, it is evident from the scant attention that has been paid to 

 it in the literature of economic entomology that this rarely occurs. 

 The best remedy is a strong spray of Black -leaf 40, 1 pint to 100 gals., 

 to which 4 lb. of soap have been added. This should be applied soon 

 after the insects hatch and with as high a pressure as possible.

 Another species is added to the Membracidae of Nova Scotia pre- 

 viously recorded [see this Review, Ser. A, vii, p. 177]. This is Enchenopa 

 binotata, Say, found on climbing bittersweet, locust and butternut ; on 

 the first-named plants eggs are deposited in the stems and covered 

 with a frothy secretion ; on butternut they are laid in the buds and 

 are not covered with froth.
