The Longicorn borer [Phoracantha semipunctata, F.] in Eucalyptus, 

 introduced from Australia, is reported from various new localities. 

 It is largely spread by unbarked gum poles from infested plantations. 



The tobacco crop of the Kat River Valley is estimated at only 10 

 per cent, of that of 1921 owing to damage by the tobacco slug [Lema 

 bilineata, Germ.]. 



An exceptional abundance of crickets has been reported from 

 Bloemfontein, the species concerned being probably Brachyirypes 

 membranaceiis, Dru. 



A Nematode, Aphelenc/ms sp., is recorded from locally grown 

 chrysanthemums, and the Pyralid, Leucinodes orbonalis, Gn., from 

 Cape gooseberry {Physalis peruviana) and from P. minima. 



The Poplar Leaf-beetle, Melasoma populi, attacking Willows. —

 pp. 118-119. 



A copper-lime solution of f-1 per cent, strength with the addition 

 of • 15 per cent, of Urania green is advised as a spray against Melasoma 

 populi attacking willows in the Moselle region.

This is the first of a series of three papers on Cydia pomonella, L., 

 and contains an account of the nature of the injury done, the habits 

 of the moth, the measures employed against it in Germany, and advice 

 as to the best combative method. During winter the trees must be 

 cleaned of dead bark, moss, etc., and painted with a fairly thick lime- 

 wash containing 10 per cent, of fruit-tree carbolineum. A powerful 

 arsenical spray, directed so as to penetrate the recesses of the calyx, 

 must be applied immediately the petals fall. One application, properly 

 made, killed 99-01 per cent, of the larvae, and as three sprayings 

 only resulted in 99-42 percent, killed, their expense is not warranted. 



Lankester (C. H.). Coffee. — Uganda Protectorate, Dept. Agric, 

 Kampala, Circ. 7 [n.d.], 26 pp., 1 plate. [Received 7th June 

 1922.] 



In this report on the coffee cultivation in Uganda, with comparative 

 notes on Costa Rica, a chapter is devoted to the diseases and insect 

 pests occurring in the two countries. 



Apparently all pests existing in Costa Rica conjointly cause less loss 

 to the coffee industry than Antestia lineaticollis alone does in Uganda. 

 At present the only practicable method of controlling this bug appears 

 to be the encouragement of Hymenopterous parasites and hand- 

 picking ; when pruning is resorted to, the thinnings should be burned 

 so as to destroy the eggs. Other pests occurring in Uganda are 

 Pseudococcus sp., which attacks the roots, but is not sufficiently 

 injurious to necessitate remedial measures ; a moth, Metadrepana glauca, 

 causing widespread defoliation, and against which spraying with arseni- 

 cals and hand-picking is advised ; and Stephanodcres hampei (bean 

 borer), which was particularly abundant during 1921. Field control 

 of the latter is very difficult ; in the case of slight attack picking and 

 destruction of infested berries is advocated. Many individuals were
