THE HOP LOUSE IN OREGON. 



Mr. F. L. Washburn, the entomologist of the Oregon Experiment 

 Station, has just issued a circular asking for information regarding 

 this insect. He asks of the growers whether there are cultivated plums 

 or prunes or any wild plums or plum seedlings near their hops, and 

 also requests information as to the exact distance of such plants from 

 the hop fields. He prefaces his questions by the following remarks: 



Siuce the presence of the Hop Ijouse {Phorodon htimiiU) in Oregon has been reported, 

 careful examinations of aliected yards have been made and the results apparently 

 corroborate the results of observations made in Europe and America contempora- 

 neously by the Department at Washington. These results are summarized in the 

 statement that "the eggs of the Hop Louse are laid in the autumn on plums and 

 prunes, more particularly the former." 



This is now borne out by personal observations in this State, thousands of eggs 

 having been found on seedling thicketo of plums near an infested hop yard, while 

 cultivated prunes in the vicinity were not affected. 



It is for the purpose of gathering statistics upon this matter, i. e,, the varieties of 

 plums preferred, and situation of plums with regard to hop yards that this circular 

 is issued, in order to record such facts in bulletin report, to be shortly issued, treat- 

 ing of remedies, etc. 



It is hoped and expected that every progressive hop-grower will interest himself in 

 answering the following questions. The greatest accuracy in the replies is necessary. 



COLLECTIONS OF COLEOPTERA — A RECENT IMPORTANT SALE. 



We are indebted to a well-known English entomologist, and valued 

 correspondent, for the following information, which will be of great in- 

 terest to all of our readers who are students of the Coleoptera: 



An important collection of one of the chief families of insects has re- 

 cently changed owners. Dr. Sharp, of Dartford, England, having ceded 

 his collection of Lamellicorns to his friend M. Rene Oberthur, of Rennes, 

 France. The collection of beetles, now in the possession of Mr. Ober- 

 thur, is richer than any other, and resulting as it does from the amal- 

 gamation of several important collections, contains so many types and 

 authenticated specimens that we have no doubt the following particu- 

 lars as to some parts of it will be found of interest to savants as well as 

 to those who are not aware of the great numbers of species of insects 

 that have been already described, and which it is necessary to accumu- 

 late as the foundation of a general collection of insects of the world. 



For many years the collection of the late Count Mnizech, of Paris, 

 was the most renowned private accumulation of Coleoptera in the world. 

 This collection shortly before the death of the Count passed into the 

 possession of Meinheer von Lansberge, governor-general of the Dutch 

 East Indies, who added very largely to it by purchases and by collec- 

 tions formed under his supervision in the East Indies and has now 

 recently parted with it to M. Oberthur. 



The latter gentleman was also fortunate in obtaining the collection 

 of CarabidsB of the late Baron Cbaudoir, containing the greater part of 

 the types resulting from a lifetime of work in descriptive entomology.
