Ganado. [General Information about Ticks and Bovine Piro- 

 plasmosis.] — Gaceta Rural, Buenos Aires, xv, no. 176, March 

 1922, pp. 931-937. 



The nature of piroplasmosis in South America and its effect upon 

 cattle are discussed. Much has been done in Argentina, where the 

 disease is endemic, by dividing the country into zones that are tick- 

 infested, intermediate and tick-free. This, however, is not sufficient, 

 as it merel}' prevents the extension of the disease ; the campaign 

 should be carried into the infested zones also until the tick is exter- 

 minated. Under the present system, the tick-free zone has scarcely 

 increased at all in the course of several years. More money is required 

 to carry out a successful campaign, the prejudice of many stock- 

 owners has to be overcome, and there must be better co-operation 

 between ranchers in the infested zones. The methods of the campaign 

 in the United States are reviewed as an example, and the necessity 

 for equal thoroughness in Argentina is urged.

The species that forni the subject of these notes are the different 

 types of Ceratopogon sens. lat. from Meigen's private collection, which 

 may therefore be held to be the types used for the original descriptions. 

 A number of errors are rectified. The synonymy is established for 

 several species, the characters of which were not sufficient]}^ elalrorated 

 in Meigen's descriptions. 



The species of which the nomenclature is changed include : — 

 Atrichopogon lucorum, Meig. {sylvaticus, Winn.), A. winnertzi, n. n., 

 {lucorum, Winn., nee Meig.), Bezzia annulipes, Meig. {solstitialis, 

 W^inn.), Clinohelea luteitarsus, Meig. {subsessilis, Goetgh.), Cidicoides 

 chioplerus, Meig. {amoeniis, Winn.), C. nubeculosus, Meig. {ptindati- 

 collis, Goetgh.), C. ohsoletus, Meig. [varius, Goetgh.), C. stigma, Meig. 

 {kiefferi, Goetgh.), Forcipomyia hipunctata, L. {disticta, Kieff.), Palpo- 

 fnyia arniipes, Meig. [rufipectus, Winn.), P. ferruginea, Meig. {fulva,

 and Psilohelea niveipennis, Meig. [candidata, Winn.). PcJpomyiapicta,

Macdonald (A. S). Observations on an extensive Human Infection 

 by Sarcoptic Mange of the Horse. — The Lancet, London, 15th 

 April 1922. (Reprinted in Vet. Jl., London, Ixxviii, no. 5, May 

 1922, pp. 166-169.) 



Of a number of veterinary students engaged in post-mortem 

 operations on a Korse strongly infested with Sarcoptes scabiei, about 

 53 per cent, became infected with the mite, while of those whose 

 hands and clothing came into direct and prolonged contact with the 

 carcase, 100 per cent, complained of subsequent symptoms. As the 

 morbid conditions were rapidly recognised only a few cases of a slight 

 dermatitis were the result. In this case the mites appear to have 

 migrated to human hosts, passing through the clothing with little 

 delay, and setting up irritation within a period of 2-24 hours.
