treatment, including plana for a dipping plant. Arsenical dips, coal-tar creosote 

 dips, and nicotin solutions may be used for dipping cattle to destroy lice, two 

 or more treatments with one of which should be given 15 to 16 days apart. 



Methods of control of the clothes louse (Pediculus humanus [vestimenti]), 

 W. MooRE {Jour. Lab. and Clin. Med., 3 (1918), No. 5, pp. 261-268). — The 

 author's investigati9ps here reported, conducted at the Minnesota Experiment 

 Station, show that sachets (small bags) of naphthalene, camphor, sulphur, 

 paradichlorbenzene, and various other chemicals, worn about the neck or the 

 waist, are not successful in eliminating the body louse. 



" Talc 20 gm., creosote 1 cc, sulphur 0.5 gm. is six times as effective a louse 

 powder as NCI [naphthalene 96 per cent, creosote 2 per cent, and iodoform 2 

 per cent], •causing less irritation to the skin and, being dry, is easier to apply. 

 Impregnation of the underwear does not appear promising, but a cheesecloth 

 suit impregnated with saturated solution of sulphur in creosote could be suc- 

 cessfully worn outside the underwear. Chlorplcrin can be used as a funiigant, 

 penetrating the clothing and killing the lice in all parts of the clothing in 15 

 minutes and the eggs in 30 minutes. By increasing the heat in tlie fumigation 

 chamber, the time required to kill the eggs could be reduced."

The pink bollworm of cotton, E. E. Scholl (Farm and Ranch, 36 (1917), 

 No. 50, p. 2, figs. 4)- — -A- brief account of the appearance of this pest in Texas 

 and measures taken for its eradication. A law enacted by the Texas legis- 

 lature which became effective December 28, 1917, makes it possible for the 

 governor to quarantine any county or area where the pink bollworm is found 

 and he may, upon the advice of the U. S. Secretary of Agriculture, restrict and 

 regulate the growing of cotton in the border counties when the pink bollworm 

 is found in Mexico within 50 miles of the Rio Grande. 



Report on the pink bollworm in the cotton districts of northeastern 

 Brazil, A. M. da Costa Lima (Relatorio sobre a Lagarta Rosea do Capulho 

 {Pink Bollworm) nos Algodoeiros do Nordeste. Rio de Janeiro: Govt., 1917, 

 pp. 50, pis. 4; rev. in Rev. Appl. Ent., Ser. A,. 5 (1917), No. 12, p. 537).— This 

 is a report to the Brazilian minister of agriculture on the pink bollworm 

 ([Gelechia] Pectinophora gossypiella) in Brazil, accounts of which pest in 

 that country by Hunter (E. S. R., 37, p. 358), Busck (E. S. R., 37, p. 564), and 

 Green (E. S. R., 38, p. 562) have been previously noted. 



Notes on its natural enemies and on other cotton pests in northeastern Brazil 

 are included, as is a bibliography of 28 titles. 



Outbreaks of the elegant looper (Philtrsea elegantaria) on privet in Loui- 

 siana, E. S. Tucker (Ent. News, 28 (1917), No. 9, pp. 394-396) .—These u5tes 

 relate to the occurrence of the elegant looper on Amoor privet (Ligustrum 

 amurensc) at Baton Rouge, La., in May and June, 1913. There was a high 

 percentage of parasitism by Chalcis ovata, and specimens of Eutelus sp. and 

 Phorocera (Euphorocera) claripennis were also reared.
