Aedes metalepicus, sp. n., from the Italian Alps is closely related to 

 the Canadian A. jmllatus. It may possibly be the same as A. 

 jugorum, Vill, or Aedes alpinus, L., but the descriptions of these two 

 species are not full enough for a certain conclusion to be drawn. It 

 is considered that Aedes nigripes, Zett., is a synonym of A. alpinus.

This group extends throughout the tropics and into the warmer 

 temperate regions in North and South America. Thirty-nine species

 corentynensis, C. (Ch.) vapulans, C (Ch.) comminutor, C. {Ch.) castor, 

 C. (Ch.) maxinocca, C. (Ch.) tosimus. C. (Ch.) vaxus, C. (Ch.) bibidus, 

 C. {Ch.) jonistes,C. {Ch.) idottus, and C.{Ch.) xmyZis, all from Surinam. 

 A key, based on characters of the genitaUa, is given of the species 

 noticed.

The lessons of the war, and the steps taken by the various nations 

 to combat insect-borne diseases, are reviewed. 



The four most important groups of insects are : — Lice, carrying 

 exanthematic typhus, recurrent fever and trench fever ; mosquitos, 

 carrying malaria, and yellow fever ; fleas carrying plague ; and 

 flies, which may be concerned in the spread of typhoid, dysentery, 

 cholera, dipthheria, ophthalmia, infantile paralysis, tuberculosis, and 

 leprosy.

In this article on Brazilian leeches the suggestion is made that in the 

 genus Haementaria may be found the vectors, perhaps the exclusive 

 vectors, of the trypanosomiasis in equines known as Mai de Caderas.
