Dept. Agric, Washington, B.C., Farmer's Bull. 801, August 

 1919, 30 pp., 14 figs. [Received 3rd March 1920.] 



This is a revised version of a bulletin previousl}^ noticed [R.A.E., 

 B, vi, 14]. 



In place of the sulj)hur ointment suggested for the treatment of 

 poultry infested with the mite, Cnemidocoptes gallinae, Raill., a dip 

 consisting of 2 oz. of flowers of sulphur and |- oz. of laundry soap to 

 1 U.S. gal. of water is advocated. 



The birds should be completely submerged and the feathers ruffled. 

 The dip must be stirred during the treatment to keep the sulphur in 

 suspension. The addition of f oz. of sodium fluoride makes the dip 

 equally effective against lice. 



In dipping pigeons in sodium fluoride about | oz. to 1 oz. of laundry 

 soap should be added to each U.S. gal. of water to ensure penetration 

 of the dip.

 November 1919, 76 pp., 22 fios., 2 plans. [Received 10th March 

 1920.] 



Various districts of the Federated Malay States, including Kuala 

 Lumpur and Gemas, have been surveyed with the object of ascertaining 

 the prevalence of Anophelines and the practicabihty of anti-malaria 

 work. 



The following species were found : — A. maculatiis, A. hanvari. 

 A. subpictus (rossi), A. kochi, A. tessellatus, A. aconitus, A.fuliginosus, 

 A. barbirostris , A. hyrcanus [sinensis), A. leucosphyrus, A. aitkeni, 

 A. umbrosus, A. hunteri, A. novumbrosus, and A. alhotaeniatiis var. 

 montanus. 



A. maculatus proved to be the most abundant species ; A. aitkeni 

 and A. leucosphyrus' were generally found in the jungle and secondary 

 growth ; the other species usually infested the open floors of the 

 ravines. The larvae of A. maculatus were chiefly found in the fresh 

 spring or seepage waters which occur in the cuttings, embankments 

 and cross drains of the railway. This is probably the permanent source 

 of infestation in Kuala Lumpur from which other sources of fresh 

 water become infested. This species does not breed under the shade 

 of secondary growth or jungle, but as the slightest opening will give rise
