Brunetti (E.). Review of Progress in our Knowledge of Oriental 

 Diptera during the last two Decades. — Proc. Asiatic Soc, Bengal, 

 Calcutta, xiv, no. 9, April 1919, pp. 358-371. 



The Diptera of economic importance referred to in this paper in- 

 clude a number of Simuliidae, some species of which bite viciously, 

 especially m the hills, where they are sometimes fairly common. 

 S. indicmn, Becker, the fir~t species to be described from Assam, is pro- 

 bably the commonest, while S. striatum, Brunn., occurs as far south as 

 Ceylon, and S. nobile, Meij., in Java. Some 360 species of Oriental 

 CuLiciDAE have been recorded, though these are probably not all valid. 

 Comparatively few additions have been made to the knowledge of the 

 family Tabanidae, which is abundantly represented, close on 200 

 species having been catalogued. 



In the small family Oesteidae, the species known in .1896 have not 

 been added to. About 20 Oriental species of Muscinae have been re- 

 corded, though some appear to require corroboration. The common 

 European dung fly, Scatophaga stercoraria, L., has not previously been 

 recorded frcm the East, though it has been found quite commonly by 

 the author m Mussoorie and Darjiliag. About a dozen species of 

 Hippoboscidae and eight Nycteribiidae have recently been described. 



The Construction of Dipping Tanks for Cattle. — RJwdesia Agrio. Jl., 

 Salisbury, xvi, no. 2, April 1919, pp. 131-139. 

 Drawings and descriptions are given for guidance in the erection 

 and use of dipping tanks, and while these may be taken as generally 

 applicable, they are meant to serve only as an indication of dimensions, 

 specifications and accessory requisites of a serviceable and economical 

 dipping tank and are subject to modification to suit individual ideas 

 and circumstances. A schedule gives the approximate capacities 

 of a tank built to the dimensions shown on the drawing and many 

 hints on dipping and the maintenance of the strength of the dip are 

 iacluded. 



Sinclair (J. M.). Management of Dipping Tanks. — Rhodesia Agric. 

 Jl., Salisbury, xvi, no. 2, April 1919, pp. 139-141. 



Notes are given on the management of the dipping solution and 

 dipping tanks generally, which it is hoped will be of assistance to stock 

 owners, particularly in the matter of maintaining the exact strength 

 of the liquid in the tanks [see this Review, Ser. B, vi, p. 218].
