anopheline mosquitoes have been extensively, but not intensively 

 and exhaustively, studied by Giles (1904), Banks (1906), Lud- 

 low (1908), and others. The following species have been 

 credited to the Philippine Islands:^ 



Myzomyia funesta Giles. Pyretophorus pitchfordii Giles. 



Myzomyia thorntonii Ludlow. Myzorhynchus barbirostris van 



Myzomyia mangyana Banks. de Wulp. 



Pseudoinyzomyia rossii Giles. Myzorhynchus pseudobarbirostris 



P8eudomyzo7nyia hidlowii Theo- Ludlow, 



bald. Myzorhynchus sinensis Wiede- 



Psuedomyzomyia indefinata Lud- mann.

Stethomyia pallida Ludlow. Nyssorhynchus fuliginosus Giles. 



Pyretophorus minimus Theobald. Nyssorhynchus philippinensis Lud- 



Pyretophorus freerse Banks. low.

 low. 



It is probable that a revision of the synonymy of these species 

 would reduce the number as well as change the names of some 

 of these species, and it is certain that a more intensive study 

 of the anopheline fauna of these Islands would disclose other 

 species. As they stand, only 6 of the 17 species are reputed to 

 be capable of transmitting malaria. Of these. Anopheles funesta 

 probably does not occur in the Philippines, the capability of 

 Anopheles rossii to transmit malaria is disputed, and the specific 

 validity of Atiopheles ludlotvii is doubtful. 



Of the 5 species considered in this paper, namely, Anopheles 

 febrifer Banks sp. nov., Anopheles rossii Giles, Anopheles bar- 

 birostris van de Wulp, Anopheles sinensis Wiedemann, and 

 Anopheles maculatiis Theobald emend. Stanton, 2 are not con- 

 tained in the above list and have not hitherto been credited to 

 the Philippine Islands and 1 is a new species. 



Anopheles febrifer was found very prevalent in Laguna 

 Province. We have been unable to identify it with any of the 

 hitherto described species of anophelines, although for a time 

 we were inclined to believe it was the same as that identified by 

 Ludlow in the Philippines as Myzomyia funesta. Mr. Banks, en- 

 tomologist of the Bureau of Science, to whom it was referred, 

 decided that it was a new species and named it Myzomyia febri- 

 fer.* The more distinctive characters of the female of this 

 species are as follows : 



A small anopheline mosquito. Head dark brown, with white 

 upright forked scales in the middle and a tuft of white hairs
