Derivaux (R. C). a Note on the Predaceous Habits of Dineutes 

 (" Whirligig Beetles ") toward Anopheles Larvae. — Public Health 

 Repts., Washington, D.C., xxxi, no. 20, 19th May 1916, 

 pp. 1228-1230. 



In the course of a sanitary survey conducted in Maryland during 

 the summer of 1915, observations were made on a Gyrinid beetle, a 

 species of Dineutes, an aquatic insect enemy of Anopheline larvae. 

 In many instances even where the beetles were numerous, Anophehne 

 larvae were not particularly difficult to find and a number of areas 

 occurred where their presence had no appreciable influence. 



It was, however, found that in an artificial container, such as a 

 basin filled with clean water, Anophehne larvae were quickly captured 

 and eaten, but the addition of surface debris, twigs, etc., gave very 

 different results, only a few of the larvae being captured, and these, 

 apparently, accidentally. The beetles seem to have great difficulty 

 in discovering the larvae when concealed. It is therefore probable that, 

 under natural conditions, these beetles are of little practical importance. 



Rat-prooflng Ordinance held valid. — Public Health Repts., Washington, 

 D.C., xxxi, no. 22, 2nd June 1916, p. 1359. 



The Supreme Court of Louisiana has upheld the Rat-proofing Ordi- 

 nance adopted by the Commission Council of the city of New Orleans 

 in June 1915. This ordinance requires the rat-proofing of all structures 

 in the city, and makes it unlawful to construct or maintain any 

 structure which is not rat-proofed as provided by the ordinance. 



Kellog (V. L.). The Transportation of Insects, with Special Reference 

 to Disease Carriers. — J/. Socialogic Med., Pittsburg, Pa., xvii, 

 no. 3, June 1916^ pp. 149-162. 



Almost any insect that associates at all closely with man is a 

 potential disseminator of germ-caused human disease and the majority 

 of such insects are cosmopolitan, owing to transportation by man. 

 As the distribution of disease-carrying insects is therefore chiefly due 

 to human action, it should be possible to control it successfully.
