 received on a banana plant from Brazil. Egg-masses of Orgyia 

 (Notolophns) antiqua, the tussock moth, have been taken on various 

 plants from Denmark, Holland, France and Belgium. Cocoons of the 

 Limacodid, Cnidocampa flavescens, were found on Japanese stock. 

 The citrus leaf-miner, Phyllocnistis citrella, has been detected on 

 Citrus and Atalaniia from the Phihppine Islands ; this species 

 is especially injurious to nursery stock in India. Puparia of Toxo- 

 trypana curvicaitda, the papaya fruit fly, were received in a package 

 containing an unknown plant from Mexico. The following Coccids 

 have been reported frequently : — Aspidiotns destructor, Sign., on

Headlee (T. J.). The Essentials of Insect Control. — Jl. Econ. Entom.^ 

 Concord, vii. no. 2, April 1915, pp. 271-276, 



This subject is treated from the standpoint of the official concerned 

 with insect control, and deals with the routine work of preventing 

 foreign insect pests from becoming estabhshed within the official's 

 territory, as well as of preventing insects already established from 

 assuming the character of serious pests. In order to prevent 

 undesirable insects from becoming established, it is necessary to close 

 the channels through which they naturally enter. In the author's 

 opinion, the most efficient protection of any territory will not come 

 through increasing the complexity of certification, but rather through 

 co-operation of officials, which will give the information sought. As 

 the protection of the territory depends upon the more or less complete 

 examination of stock coming into it, a very valuable factor is advance 

 information of the source, nature, extent, destination, probable date 

 of arrival, and consignee of each of the various shipments. The 

 prevention of the establishment of new pests is far more effective than 

 is the control of outbreaks of insects already estabhshed.
