contained in the 3rd volume of Theobald's Monograph which 

 appeared whilst Blanchard's work was in the press. 



Miss Ludlow's paper on the connection between malaria and 

 the occurrence of various species of mosquitoes in the Philippines 

 contains very extensive information respecting their distribution. 



Many of the species appear widely distributed. Mvzomyia 

 iudlowii being reported from no less than 42 different localities 

 in these Islands, M. indefinita from 26, M rossii, vanus, pseudo- 

 barbirostris , funestus and barbirostris from ten or more localities 

 each, besides other species from a lesser number of localities each. 



She notes that it is probable that some species may pass 

 through the dry season as adults, hibernating amongst the dry 

 vegetation, and also notes that in localities where the rainy season 

 advances graduall}^, the Anophelinae are more numerous and exist 

 in considerable numbers throughout a good part of the dry season, 

 whereas in localities where the rainy season is introduced b}^ very 

 excessive and constant deluges they are markedly less in numbers, 

 presumably by the breeding places of the insects in their earlier 

 stages being washed away. 



'' Four Anophelinae, funesta, barbiroslris, fuliginosus, and 

 Iudlowii . . . seem likely to be acting as hosts for the malarial 

 parasite in the Philippines, and concerning .S/eo-o^/ym calopus Mg.(:= 

 S. fasciata F.), Culex fatigans W., and Mansonia unifonnis Theob., 

 there are too few data to judge if they be carriers of disease" 

 (Ludlow). Regarding Stegomvia fasciata, the acknowledged sole 

 carrier of yellow fever, this author significantly remarks : " Yellow 

 fever has so far never been present in the Philippines. The wide 

 distribution of S. calopus (= S. fasciata F.) is, however, very 

 suggestive taken in connection with the building of the Panama 

 Canal, as to the result likely to follow, should yellow- fever-infected 

 mosquitoes or patients in the proper stage of the disease reach the 

 Islands." 



Mr. G. F. Leicester in his important and extensive paper on 

 • The Culicidae of Mala3''a " devotes over 250 pages to fully redes- 

 cribing the mosquitoes of this region, including nearly a hundred 

 new species. In his preface he notes that the 3rd volume of 

 Theobald's Monograph appeared just before the publication of his 

 own work and that an appendix will be necessary, involving some 

 changes of nomenclature, and that a further paper on the larval 

 characters may eventually follow. 



In this paoer he devotes 14 piges to the breeding grounds of 

 mosquitoes with some notes on collecting and preserving them, 

 but although he seems to have bred a great number of the species 

 and fully described numbers of them from long series of fresh 

 specimens he gives no definite dates of appearance. 



A further report by Theobald on the Indian Museum Culicidae 

 (th'e 2nd) has recently been issued ' in which four new genera 

 and twenty-one new species are described. It has appeared 



' Rec. Ind. Mus., iv, i — 33 (19 10).
