 pp. 1535-1536. 



Anopheles brevipalpis, Roper, is described from Bangka, and the 

 characters differentiating Anopheles {Neomyzomyia) pimctulatus, Don., 

 from New Guinea, from A . annulipes {punctulatus) var. moluccefisis, Sw., 

 are given.

The antipsoroptic value of a remedy depends on a number of 

 factors including wetting power, harmlessness to the skin, cost and 

 acaricidal power. An investigation of 15 of the substances usually 

 employed against mites was made, all the information being tabulated. 

 Sulphurous anhydride, 2 J parts in solution in 100 parts oil, such as 

 ground-nut oil, is the best preparation obtainable for practical purposes, 

 while a tepid aqueous emulsion of cresyl of 1-2 per cent, strength is 

 the most effective disinfectant. The effect of heat on cresyl is remark- 

 able, a 1 per cent, emulsion at 37° C. [98-6° F.] being quite as effective 

 as pure cresyl at a normal temperature. The value of Helmerich's 

 ointment {R.A.E., B, vi. 111] seems to lie in its effect on the removal 

 of crusts and the consequent automatic cleansing of the skin.

The view is expressed that fleas are a sub-order, Aphaniptera, of 

 the Coleoptera. This sub-order, derived from the Staphylinoidea, 

 should be treated (as is the case with Stylopidae) as separate from 

 the true beetles. It comprises the one family Pulicidae.

The general structure of Ixodids is discussed, and the life-history and 

 habits of Boophilus (Margarop^is) [annulatus], the vector of bovine 

 piroplasmosis, are described. The most favourable period for 

 development in Argentina is from January to April ; the virulence 

 of the tick increases with succeeding generations, and the life-cycle 

 is then at its shortest. Particular attention should be given to cattle 

 at this time, lest native animals lose their natural resistance and 

 imported ones that have been artificially immunised meet with such 

 virulence that they lose their acquired immunity.
