first week in August, Natural enemies included Coccinellid larvae 

 during the early part of the season and Dipterous larvae at a later 

 period. Return migrants were found on 2nd October ; males were 

 observed on 8th and a mature oviparous female on 13th October. 

 The beginning of egg-laying was not determined. Viviparous apterous 

 forms occurred on Plantago major and P. lanceolata until 4th December. 

 On the apple viviparous and oviparous forms remained until the 

 middle of that month. 



A. pomi is found on the 3^oung growth of nursery and young orchard 

 trees. This species was first observed on 6th April and hatching 

 extended over at least three weeks ; it was not common until the 

 middle of June and began to decrease in numbers during the second 

 half of July. Mature males were first seen on 22nd September and 

 mature oviparous females a week later. Oviposition began during 

 the first week in October and continued until December. Eggs were 

 deposited on the first year's wood, near the ends of the twigs, in the 

 axils of the leaves. 



A list of recent Hterature bearing on this subject is given.

This paper describes the same outbreak of Galerucella cavicollis, 

 Lee, as that recorded in a paper previously abstracted [see this Review, 

 Ser. A, iv, p. 309]. 



The most suitable control measure is to spray cherry and peach 

 trees as soon as the adults appear, with nicotine sulphate (40 per cent.), 

 ^ pt. in 60-80 U.S. gals, water. For cherry trees, lead arsenate 

 solution (8 lb. paste to 100 U.S. gals, water or Bordeaux mixture), 

 or arsenate of lime (6 lb. paste to 100 U.S. gals, water) may be used. 

 Shaking the beetles from the trees into sheets is recommended when 

 the infestation is serious.

The duties of the Entomologist during 1915 included the inspection 

 of nurseries, etc., the distribution of information concerning, and the 

 identification of, injurious insects, the control and prevention of crop 

 pests and the regulation of the sales and shipments of nursery stock. 

 Owing to the exhaustion of funds, adequate measures could not be 

 taken against citrus canker and consequently the disease spread 

 rapidly. The cottony cushion scale [Icerya purchasi] was abundant 

 in and near New Orleans and prohibited the planting of many shade 

 and ornamental trees. Demonstration sprayings against this and 

 other insects were conducted on several occasions.
