Hydrotaea meteorica, L., has been found on cattle in Montana and 

 North Dakota. In the former State this species is abundant and 

 troublesome, as it enters the eyes and ears of cattle to feed on the 

 moisture present. Lynchia maura, Bigot, a common parasite of the 

 domestic pigeon in the Mediterranean region, occurs also at Key West, 

 Florida, in Georgia, Cuba, Brazil and Venezuela. The same species 

 has recently appeared in Hawaii. In Florida the presence of this 

 parasite was accompanied by a fatal disease. The Borborid, Leptocera 

 sylvatica, Meig., was taken from a compost heap at Arlington, Virginia. 

 The remaining species, Pegomyia hyoscyami, Panz., occurs on various 

 food-plants.

Supply of Dipping Material. — Rhodesia Agric. Jl., Salisbury, xiii, no. 2. 

 April 1916, pp. 178-181. 



Owing to the shortage in the supply of cattle dip, arrangements have 

 been made by the Government for the distribution of arsenite of soda 

 for the preparation of the Natal Laboratory Dip, at the rate of 100 lb. 

 for £2 IO5. Od. This arsenite contains about 60 per cent, arsenic, 

 or 20 per cent, less than that generally used for preparing the dipping 

 fluid. The following formulae are therefore given for the preparation 

 of the three-day dip and seven-day dip respectively :■ — (1) 5 lb. 5 ozs. 

 arsenite of soda, 1 gal. paraffin, 3 lb. soft soap, 400 gals, water ; 

 (2) 10 lb. 10 oz. arsenite of soda, 2 gals, paraffin, 5|- lb. soft soap, 

 400 gals, water. The soap is dissolved in a sufficient quantity of hot 

 or cold water and the paraffin is added to the solution, the whole being 

 stirred until an emulsion is formed. A solution of the arsenite of soda 

 is then added, and the quantity made up to 400 gals.

Persons in search of game in the southern part of the Sebungwe
