cherry slug", Eriocamjm cerasi, has been doing some little damage in 

 parts of South Australia, and the Minister of Agriculture has issued 

 a proclamation prohibiting the introduction into the colony of any tree, 

 plant, or fruit in any way infested with this insect. Announcement is 

 made of a public demonstration of the benefits to be derived from 

 spraying fruit trees for protection against fungous diseases and the 

 attacks of insects shortly to be held under the auspices of the Agri- 

 cultural Bureau. The Phylloxera agitation still continues, and the 

 officers of the Bureau are coming to the conclusion that in the use of 

 American resistant stocks the salvation of the vine-growing industry 

 of the colony is to be found. An a])plication has been made for the 

 removal of the restriction against the importation of oranges and 

 lemons affected with Mytilaspis citrieola, but in view of the fact that 

 this insect is not known in South Australia the application was denied. 



AN IMPORTANT MONOGRAPH. 



]\I. (1. V. Berthoumieu, in the first number of the current volume of 

 the Annales de la Societe Entomologique de France, has begun the 

 publication of what bids fair to be a very complete monograph of the 

 Ichneumouidiii of Europe. The first installment of 35 pages contains 

 only preliminary matter. He divides the family into six tribes, which 

 correspond to the five subfamilies given in Cresson's Synopsis, with the 

 addition of the Agriotypini, and gives at length the general habits and 

 characters of the typical tribe Ichneumonini. Im])ortant original obser- 

 vations are given upon the larval development of Ichneumon rubens, 

 and the statement is made that the insects of this tribe or subfamily 

 are exclusively parasitic upon the larvae of Lepidoptera. In this opin- 

 ion M. Berthoumieu follows Bridgman and other observers. Upon pages 

 151-152, vol. Ill, Insect Life, in recording the office rearings of para- 

 sitic Hymenoptera, we have given three cases in which species of this 

 subfamily have been reared from sawfly larvte, and we are inclined to 

 think that the general statement must be modified. 



COOPERATIVE WORK AGAINST INSECTS. 



On page 376 of the last volume of Insect Life we mentioned, under 

 the above heading, the result of the offering of prizes by the Genesee 

 Valley Forestry Association for the collection of cocoons of some insect, 

 which we concluded, from the context in the newspaper paragraph in 

 which we observed the statement, to be a Clisiocampa. 



Mr. M. Y. Slingerland, of Cornell University, seeing this item, has 

 put us in possession of the facts in the case, and we quote his interest- 

 ing letter in full: 



In 1892, while attending the Association of Economic Entomologists at Rochester, 

 aud passing to and from the meetings, along some of the beantifully shaded streets, I 

 saw immense numbers of the egg-masses of the w.hite-raarked tussock-moth (Xoto- 

 lo2)hus orgyia) on the trunks of the trees and in many angles of the dwelling houses
