 they will hve many days without food.

The cattle tick, Margaropus annulatus, occurs in torrid and subtorrid 

 zones having a low altitude and has been reported from the United 

 States, Mexico, South America, Asia, Africa and Austraha. The loss 

 •caused by it, which in the United States alone amounts to one hundred 

 million dollars annually, results from the actual deaths from Texas 

 fever in native and imported animals, the stunting of growth in those 

 which survive, damage to hides from tick bites, and the restrictions 

 to trade and transportation of animals to the most suitable feeding 

 grounds. Regions infested by the parasites are especially adapted 

 to the economic production of beef and dairy products, so that the 

 tick becomes a serious factor in the cost of living. A description of 

 the life-history of the tick is given. An efficient method of kilhng the 

 ticks consists of forcing the cattle to swim through a vat containing 

 a solution of arsenic ; the dipping must be repeated periodically if 

 the animals return to an infected pasture.

Four ticks are recorded, apparently new to Mozambique. They 

 have been identified by Dr. Nuttall as Rhipicephalus falcatus, R. 

 ?naculatus from pigs, R. pulchellus from a mule, and R. neavei from a 

 bush-buck. Theileriasis (East Coast fever) is reported as very 

 prevalent and causing great loss, and attempts have been made to 

 extend the use of dipping tanks, but with no great success. Cases of 

 trypanosomiasis in cattle having been detected on two farms, search 

 was made for Glossina, but none could be found, and transmission by 

 some other insect is suspected.

Detailed descriptions of both male and female of Myzomyia fehrifera 

 are given in this paper. This species has been ascertained by Drs. 

 Walker and Barber [see this Review, Ser. B, iii, p. 65] to be capable 

 of transmitting malaria. 



[As stated on p. 65, this species has already been described by 

 Theobald as Anopheles minutus and the name here proposed cannot 

 stand.— Ed.]
