mosquitos and the adoption of measures confined to those species 

 that carry the disease are the chief Hnes along which progress has 

 been made.

 In Bohemia, the beetles found in the hutches of domestic rabbits 



are nearly the same as those occurring in the burrows of wild ones. 



A list of these is given.

This review contains no new information, but gives an outline

and the measures adopted against them. It also deals with the 



transmission of disease by ticks and the prophylaxis of piroplasmosis.

 The authors agree with the view that in Germany Anophelines 

 chiefly occur in cattle sheds. The district near Halle, where their 

 previous work had been done [R. A . E., B, ix, 68], was chosen for further 

 investigations, a shed being visited on one afternoon each month from 

 March 1919 to March 1920. At first a horse was the sole occupant, 

 but in October it was replaced by rabbits, goats, pigs and domestic 

 birds. In this particular shed Anopheles maculatns was the only 

 species found. In some others a few specimens of A. hifurcatus also 

 occurred, while in others again A. bifurcatiis only was taken. 



Anophelines like dry, warm sheds, with dark corners, where numerous 

 cobwebs give facilities for settling. This may point to the value, 

 already mentioned by the authors [loc. cit.], of hygienic conditions as 

 a means for reducing the number of mosquitos in sheds. It is in sum- 

 mer, when Anophelines are most numerous, that they are least exacting 

 in their choice of shelters, so that they may then be found in well-lit 

 sheds, especially if the latter are near suitable breeding-places. Some 

 Anophelines suck blood even in the winter, which is not the case 

 with Culicines, which hibernate in cellars. This is probably due to 

 the greater activity, and consequent need for food, of Anophelines in 

 sheds as compared with Cnlex in cool cellars. Anophelines in sheds 

 could not be got to bite when intentionally disturbed, but captive 

 Anophelines readily sucked blood from a finger offered to them, even 

 in winter. The desire to bite was most marked in December, and the 

 early evening hours were those in which bites were most frequent. 

 Males occurred with the females, but in smaller numbers and only in 

 summer, from June to September. Even in warmed rooms the females
