The adult beetles appear during the last week in May and first week in 

 June and feed on the upper surface of the leaves. Pairing takes place 

 during the last half of June, and larvae are found early in July. By 

 the first week in August all the larvae are in cocoons, in which they 

 hibernate among leaves on the ground. Pupation occurs the following 

 spring. Spraying the plants, especially the upper leaf surfaces, at the 

 end of May or beginning of June with lead arsenate is recommended. 



Corythitcha celtidis, O. & D. (hackberry lace-bug) was first observed 

 in New Jersey in June 1920, depositing eggs on the lower surface 

 of hackberry leaves. The eggs are laid in clusters of 4-18, and 

 hatch in about two weeks. Each of the five nymphal stages requires 

 from 2 to 4 days of very warm weather to complete its growth, cool 

 weather retarding development ; the adults emerge in 16-20 days. 

 Two generations occur in New Brunswick. Natural enemies include 

 spiders and predacious bugs. Spraying when the nymphs are first 

 noted on the lower surface of the leaves with 6 lb. whale-oil soap 

 to 50 U.S. gals, water is recommended.

P A VLO vs K Y (E . N . ) . Description of a Box for collecting and transporting 



living Insects, etc. — Parasitology, Cambridge, xiv, no. 1, April 

 1922, pp. 47-50, 1 fig. 



The box here described and illustrated has been used by the author 

 for four years and has proved most useful. The original inventor 

 is not known, and the description includes modifications adopted by 

 the author. The floor of the box is made of wire gauze secured by a 

 fillet of wood running round the lower edges of the box and screwed 

 to the lateral end walls. The rectangular compartments may be 

 subdivided by tin plates. The upper edge of each of these diagonal 

 division plates should be cut to fit the cork protruding through the 

 hd. 



This apparatus is very convenient for transporting Arthropods 

 with cannibal habits, and may also be used for sensitive insects such 

 as bumble bees and other Hymenoptera, which will survive in the box 

 much longer than in glass jars with gauze lids. As long as the gauze 

 bottom of the box is placed on the corks of another one, several may 

 be strapped together.
