The various stages in the life-history of the scab mite of the rat 

 are described as a result of careful observation of the isolated eggs, 

 larvae, nymphs and adults. The rat concerned is probably Mus 

 decunianus and the mite is probably Notoedres miiris, Megn., or perhaps 

 A'', muscidi, Oud., or A'', alepis, R & L.

 November 1920, 203 pp., 15 plates. [Received 21st May 1921.] 



The object of this monograph is to collate information on the develop- 

 ment and early stages of Tabanids, about which very little is known, 

 although the subject is an important one in view of the role played 

 by these flies in transmitting diseases of domestic animals. Previous 

 literature on the subject is not only reviewed, but the facts found 

 therein are quoted or reported, so that the work constitutes a valuable 

 compendium of information on the subject. The fact that the data 

 are all presented in English will, it is hoped, encourage English- 

 .speaking entomologists to make further investigations on the subject. 

 Short descriptions are also given of the larvae of 14 unidentified species 

 of Tahanus, with a list of the recorded parasites of flies of this family 

 and a complete bibliography.

Malaria prophylaxis, neglected during the War for increased sugar 

 production, must be vigorously prosecuted in Cuba, especially as regards 

 anti-mosquito work. Besides possessing the conditions found else- 

 where that are favourable to mosquitos, Cuba has a number of Brome- 

 liaceous plants of the genera Hohenhergia, Tillandria and Guzmania 

 that may serve as breeding-places owing to the water collected in 

 their leaves. Against the larvae, petroleum, lime (15f grammes per 

 cu. metre water), and carbide residue are recommended. Fumigation 

 with sulphur, pyrethrum, leaves of Stramonium, creolin and tobacco 

 are advised against the adults. A repellent for individual use is a
