The European Red Mite In California. The so-called citrus red spider, Tetrany- 

 chus citri Mc Gregor {T. mytilaspidis Riley), which occurs abundantly in the citrus 

 orchards of Southern California and in the deciduous fruit orchards of California, 

 Oregon and Idaho proves to be the Etu-opean red mite, Paratetranychus pilosus 

 C. & F., recently reported from Connecticut by Dr. Philip Garman. The western 

 species has been submitted to Dr. Philip Garman, Dr. H. E. Ewing and others and 

 there seems to be little doubt in the conclusions reached by the best authorities on 

 the subject. 



In the deciduous fruit orchards of the West this mite bids fair to be as serious as 

 it is in the citrus orchards. 



It probably has a very wide distribution throughout the United States because of 

 the ease of carrying the eggs on nursery trees. The small round red eggs are decidedly 

 flattened, minutely striated and usually furnished with a small stalk so admirably 

 illustrated on page 357, Vol. 14, No.4, Journal of Economic Entomology, Aug. 1921, 

 by Dr. Garman.

The Miller Memorial Beekeeping Library. The death of Dr. C. C. Miller of 

 Marengo, Illinois, made a gap in the beekeeping ranks in the United States and 

 throughout the world which will be hard to fill. With his high ability as a beekeeper, 

 Doctor MiUer possessed such rare qualities as a man that he was revered by beekeepers 

 as few if any have been. On his death there were many suggestions of ways to honor 

 his memory, and a volunteer committee of five has undertaken this. It was thought 

 best not to undertake anything which would involve the raising of a large sum. 

 The committee has decided to raise whatever could be obtained without too great 

 sacrifice and to establish a permanent endowment for a library of beekeeping in some 

 one of the leading colleges or universities in which beekeeping is taught, to supplement 

 the library purchases of the college itself. Such a memorial will in a sense go on doing 

 what Doctor Miller did so well diuing his life, namely to be of help to beekeeping. It 

 is greatly to be preferred to a pile of granite as a memorial fitting to a man of his type. 



Since there is as yet no library in the country in which there is sufficient of the 

 beekeeping literature to be fully helpful to the investigator.the establishment of such 

 a library will be an important addition to our facilities, wherever it may be established. 

 The purpose of this note is frankly to enlist the support of entomologists in this 

 movement, and to suggest that many wiU wish to add something to the fund. Con- 

 tributions of any size will be gratefully received, and should be sent to the chairman 

 of the committee, Mr. C. P. Dadant, Hamilton, Illinois.

Mealy Bug Control on Pear Trees. A considerable amotmt of work is being done 

 on the control of Baker's mealy bug, Pseudococcus marititnus Ehrh., which in some 

 orchards is a serious pest of pear trees, of which the Winter Nellis is most injiu-ed, 

 although other varieties are also attacked. During the dormant season the mealy 

 bugs and egg masses occur in quantities in crevices and under the rough bark and on 

 the imdersides of the smaller limbs. 



After first scraping away much of the loose bark on the trunks and bases of the 

 main limbs, the trees are thoroughly sprayed with miscible oil or crude carbolic 

 acid and distillate emulsion. The latter is no better than the miscible oil, but when 

 prepared at home is very much cheaper. The formula recommended is as follows
