wlien predaceous enemies began to attack them seriously, Coccinella 

 sanguinea and the Syrphid, Baccha davata, being the most important. 

 Numbers of parasites were reared from the larvae and pupae of the 

 predators, among tliem several undescribed species of Hymenoptera.

Canadian Entomologist, London, Ont., xlvii, no. 3, March 191.5, 

 pp. 97-98. 



A description is given of Megastigmus jnceae, sp. n., a Chalcid which 

 has been reared in Colorado by Mr. J. M. Miller from the seeds of 

 Picea engelmanni (Engelmann spruce), from P. silcliensis (Sitka spruce) 

 and from P. parrgana (Colorado blue spruce).

 ^Ont., xxxviii, no. 3, March 1915, p. 69. 



The common asparagus beetle {Crioceris) injures young shoots of 

 the asparagus. The beetle passes the winter in the mature stage. 

 Poultry, if allowed to run over the beds in spring, will eat large numbers 

 of the larvae. The most effective remedy is dusting the plants every 

 three or four days with fresh, air-slaked lime. 



The Control of Orchard Pests. — Canadian Horticulturist, Peterboro,Ont., 

 xxxviii, no. 3, March 1915, pp. 88-89. 



The tarnished plant bug {Lygus pratensis) appears early in spring 

 and attacks the young fruit of apple and pear trees. The best control 

 is a spray of Black Leaf 40, | lb. to 100 gals, water, when the blossoms 

 are falling. The campaign against the San Jose scale {Aspidiotus 

 perniciosHs) has had very satisfactory results and has shown the value 

 of the legislation against the importation of infested stock. The green 

 apple aphis {Aphis pomi) has been found to produce 14 generations 

 in one season, the life-cycle covering an average of 28 days. The 

 best spray is a mixture of lime- sulphur, 28° Be., Black Leaf 40 

 (1 1,500) and flour paste apphed at the time of the opening of the 

 flower buds.

 Columbia.^^(/ric. Gaz. Canada, Ottawa, ii, no. 3, March 1915, 

 pp, 216-217. 



Wireworms, cutworms, root-maggots, weevil larvae, etc., are readily 

 devoured by the common field mole. Scapanus townsendii. Bach, 

 (To^^^lsend's mole) and Neurotrichus gibbsii, Baird, (Gibb's mole) are 

 the two species which occur in the Lower Fraser Valley of British 

 Columbia. The latter is the commoner and is the species referred to 

 in this note. During the investigation into the hfe-history of the straw- 

 berrv root weevil in the Lower Fraser Valley in 1912 and 1913 [see 

 this^ Review, Ser. A, i, p. 92], it was considered that the mole was 

 probably its most important predatory enemy. During an outbreak 

 of Lycophotia margarilosa (Pcridroma saucia), the variegated cutworm,
