Bodkin (G. E.). Rice Pests in British Guiana. — Jl. Bd. Agric. British 

 Guiana, Demerara, xii, no. 4, October 1919, pp. 248-250. 

 [Eeceived 2nd February 1920.] 



Rice pests include:— The moths, Mods {Remigia) repanda, F., of 

 which the larvae destroy the foliage of mature plants ; Laphygma 

 fnigiperda, S. & A., which chiefly infests the foliage of young nursery 

 plants ; Maenas laboidbenei, Bar, the aquatic larva of which destroys the 

 foliage ; Dialraea saccharaiis, L., the larvae of which bore in the stem ; 

 an ant, Solenopsis pylades, For., which hollows out the stems of full- 

 grown plants ; a froghopper, Tomaspis flavilatera, Urich ; the 

 JPentatoraids, Mormidea ypsilon, L., which destroys the developing . 



ears, and Tibraca limhaliventris, Stal ; and a locust, Conocephaloides \/^ 

 maxillosHS, F., which destroys the foliage [see also R.A.E., A, ii, ^ 

 568, etc.]. 



The Wild Birds Protection Ordinance.— JL Bd. Agric. British Guiana, 

 Demerara, xii, no. 4, October 1919, pp. 288-290. [Received 2nd

Lime-Sulphur Spray following Bordeaux.— iV. Z. Jl. Agric, Wellington, 

 xix, no. 6, 20th December 1919, pp. 371-374. 



Experiments show that lime-sulphur following Bordeaux mixture, 

 has not reduced the apple crop in any way ; on the other hand the 

 foliage is much healthier than when Bordeaux mixture only is used, 

 the efficacy of both the sprays being the same. 



McGregor (E. A.). The Red Spiders of America and a few European 

 Species likely to be introduced. — Proc. U.S. Nat. Mus., Washington, 

 B.C., Ivi, no. 2303, 1919, pp. 641-679, 6 plates. 



A key is given to the following genera of red spiders : — Anychus. 

 iwen. n., containing A. banksi, Meg., from Florida, and A. rusti, Meg., on 

 Carica papaya in Peru ; Neotetr anychus, Trag. ; Schizotetr anychus. 

 Trag. ; Tetranychus, Duf. ; Septanychus, gen. n., containing S. tumidus, 

 Banks, and S. quinquenychus, Meg., from Florida ; and Paratetr anychus, 

 Zach. 



Keys are also given to the species of each of these genera to the 

 number of 32 including Tetranychus pacificus, sp. n., on mock orange 

 {Philadelphus gordonianus), Vicia spp., and wild currant (Ribcs s-pp.) 

 m Oregon, and on chinaberr}^ in California. 



Tragardh in 1915 [R.A.E., A, iii, 253] placed bicolor. Banks, and 

 inodestus. Banks, in Neotetranychis, but these species are now trans- 

 ferred to Paratetranychus. The author differs from the views of 

 Ewing [R.A.E., A, iii, 63] as to the synonyms of Tetranychus telarius. 

 L. He treats T. bimaculatus, Harv., and T. sexmacidatus, Riley, as 

 distinct species, and T. gloveri. Banks, as a synonym of T. bimaculatus. 

 It is doubtful whether the true T. telarius occurs in North America 

 -at all.
