reaching its maximum. As the cotton-growing region of Texas is 

 not very different chmatically from the Laguna district, and in view 

 of the fact that P. gossypiella is already present in some counties of 

 Texas, it is urged that every step possible should be taken to eradicate 

 the pest in those counties where it already exists and that every 

 precaution be taken to prevent its re-establishment in Texas.

 pp. 48-53. 



Much of the work reviewed in this report under the headings of 

 insect pests and useful insects has already been noticed in detail 

 [R.A.E., A, ix, 72-80, etc.].

 Record and Jl. Var., London, xxxiii, no. 4, 15th April 1921, p. 77. 



Attention is drawn to the occurrence of Eriosoma lanigerum on a 

 shrub [Cotoneaster sp.). This is apparently the first record of this 

 food-plant.

 Species.— £■«/. Mthly. Mag., London, 3rd Ser., no. 75, March 1921, 

 pp. 61-64. 



The thrips dealt with include Physothrips propinquus, sp. n., on 

 Pinus, which is apparently P. latus, Williams (nee Bagn.), and P. 

 consociata, Targ., {ulmifoliorum, Uzel, nee Hal.). The common species 

 on elm is Scirtothrips ulmi, Bagn., which the author now considers 

 to be a synonym of 5. ( Thrips) ulmifoliorum, Hal.

This is a popular article on the wax moth, Galleria mellonella. This 

 pest only attacks weak colonies of bees and never approaches combs 

 covered with bees ; it can be destroyed by fumigation with carbon 

 bisulphide, which is equally useful against the bacon beetle [Dermestes 

 lardarius], which feeds on wax left in dark places.

A popular account is given of the mole-cricket, Gryllotalpa gryllotalpa 

 (vulgaris), and of the measures usually adopted against it, including 

 subterranean fumigation with carbon bisulphide, napthaline, or lump 

 calcium carbide ; poison-baits ; shelter-traps and light-traps ; and 

 destruction by hand.

The authors state that their investigations on the chemical com- 

 position of lime-sulphur sprays, to which their variability of action is 

 undoubtedly due, were nearly finished when their attention was drawn 

 to Tartar's work on this subject [R. A.E., A, ii, 543], and to an earlier 

 (1910) paper by Van Slike, Bosworth and Hedges, "Chemical Investi- 

 gations of the best Conditions for making the Lime-Sulphur Wash."
