Mesochonis vitreus ; Braconidae : Apanteles militaris, Apanteles sp., 

 Meteorus communis ; Chalcidoidea : Eupteromalus sp. In the dis- 

 cussion following the paper, Mr. King stated that, in Missouri, army- 

 worms were abundant in 1913 and 1914, appearing especially early 

 in the wheat crops ; they were always preceded by large numbers 

 of bobolinks and red-winged blackbirds. In the post-holes dug for 

 the control of the pest, many Cahsoma beetles were found and were 

 sent to New Mexico for the control of the range caterpillar. According 

 to Mr. Gibson, the sudden increase in the numbers of the army-worm 

 is probably correlated with the numbers of parasitic enemies and 

 weather conditions. So far as is known, the winter is passed in an 

 immature larval stage.

 in Eastern Canada.— 45//i Ann. Rept. Eniom. Soc. Ontario, 1914. 

 Toronto, 1915, pp. 97-102, 1 fig. 



In the discussion following the paper [see this Review, Ser. A, iii, 

 p. 368], the President mentioned that experiments were being carried 

 on in the use of Coccobacillus as a means of control for locusts in Canada. 

 Up to the present no definite results had been obtained ; failure was 

 due to the fact that the culture had to be taken from Quebec to Ottawa 

 and did not remain in a viable condition for more than 48 hours. 

 This method of control has been successfully used in the Argentine 

 and in North Africa. Prof. Caesar stated that the Kansas remedy 

 had been satisfactory ; the use of 2 gals, water instead of 3 gals, had 

 seemed preferable. Twenty pounds of the bait was sufficient for five 

 acres. In Manitoba, no results had been obtained when the tempera- 

 ture was below 50° ; in the same province the use of sawdust and salt 

 instead of bran was being tested.

 Leaf-Bug {Poecilocapsus lineatus, Fabr.).- — Canadian Entomologist, 

 London, Ont., xlvii, no. 6, June 1915, pp. 181-183, 4 figs. 



On 26th July 1913, the eggs of Poscilocapsus lineatus, F., deposited 

 in stems of Weigelia were found to be attacked by a Chalcidoid larva, 

 Cirrospilus orisugosus, sp. n. The larva burrows through the pith of 

 the host plant until it reaches a row of eggs and then proceeds to 

 destroy them. About 50 per cent, of the egg-masses in the clump of 

 Weigelia examined were attacked by the parasite. The larvae reach 

 maturity before winter, but do not pupate until the following spring. 

 To secure adults, egg-masses were collected on 28th February 1914 ; 

 the larvae attacking these pupated about a week later and adults 

 emerged on 23rd March. A description of the species is given.

In studying Graptolitha {Xylina) bethunei (apple worm) in Nova 

 Scotia in 1913, it was found that the best place to collect 5th and 6th 

 stage larvae was in the leaves about the cocoons of Malacosoma disstria.
