THE PHILIPPINE MOSQUITOES. 



By C. S. Ludlow, 

 Army Medical Museum, Washington, D. C. 



In April 1901, under the authority of the Medical Department, 

 U. S. Army, there was begun in INIanila, a research having for its 

 original object some anatomical study of mosquitoes, especially 

 those connected with the transmission of malaria. However, as 

 the mosquitoes of the Philippine Islands were entirely unknown it 

 became at once evident that systematic study of these insects 

 was necessary before any anatomical problem could be under- 

 taken, and the research then became purely entomological, only 

 the correlation of the appearance of certain species with the inci- 

 dence of these diseases being left of the work in preventive med- 

 icine. The anatomical work has since, for the most part, been 

 worked out by others. 



The collections are made by the Surgeons or Hospital Corps men, 

 and, with a statement of the number of cases of malaria, dengue 

 and filariasis present during the time of collection, mailed to me. 

 While many of the collections are received in excellent condition, 

 the identification of the specimens is often much hindered, or 

 rendered impossible by carel&ssness in collecting, in preparing for 

 shipment, and by accidents incident to transportation. On this 

 account some species must wait for additional collections, often 

 a matter of months, before accurate determination or description 

 is possible. 



The following forms have been determined from these collec- 

 tions and most of them previously reported, but it seems of pos- 

 sible interest that a complete list to date should be published, 

 and this with the descriptions of some new forms are given below.
