The following species are described : — Phytoscnphus dissimilis, sp. n., 

 attacking young shoots of tea in Assam. Corigetus hidentulus, Fst., 

 a serious pest of tea in Assam. Rhynchaenus (Orchestes) mangiferae, 

 sp. n., bores the leaves of the mango tree. It is described by Bainbrigge 

 Fletcher as a minor pest of local importance. The eggs of Pachytychms 

 mungonis, si^. n., according to Bainbrigge Fletcher, are laid in a hole 

 bored in a seed of green gram [Phaseolus mungo) or cow-pea, the female 

 having previously eaten her way inside the pod. Three eggs are usually 

 laid in one pod, one at each end and the third in the middle of the pod. 

 The grub, on hatching, feeds on the seed, devouring three or four seeds 

 before it is full-fed, when it emerges from the pod and drops to the 

 ground in which it pupates. It is a local pest, which may at times do 

 considerable damage, and is said to occur more commonly on areas 

 of black cotton soil. 



YoTHERs (W. W.). Spraying Scheme for tlie Control of Insect Pests 

 on Citrus Trees in Florida. — Jl. Econ. Entom., Concord, vii, no. 2, 

 April 1915, pp. 161-164. 



The greater portion of the damage caused by insects to citrus trees 

 in Florida is due to the following species :■ — Aleurodes citri, the citrus 

 whitefly, Lepidosaphes beckii, the purple scale, Eriophyes oleivorus, 

 the rust mite, Chrysomphahis aonidum, Aleurodes nubifera, and 

 Tetranychus sexmaculatus, the red spider. Pests of secondary impor- 

 tance are Aleurodes howardii, the woolly whitefly, and Tetranychus 

 mytilaspidis, the purple mite. The pests should be killed before they 

 have done much harm to fruit or tree, i.e., in the young stage. The 

 following sprays have as a rule given satisfactory results. Paraffin-oil 

 emulsion (1 per cent, of oil) kills whitefly, scale-insects, and to some 

 extent rust mites. Spraying should be performed after the adults of 

 the first brood of whiteflies have disappeared and before the appearance 

 of the second brood. Lime-sulphur solution, appUed in June and July, 

 kills rust mites. A second spraying of paraffin oil emulsions in October, 

 kills whitefly larvae of the last brood. Soda-sulphur 1-50, added to
