PACIFIC SCIENCE, Vol. V, July, 1951 
Explanations 
In the period from 1946 to 1951, the follow- 
ing series of 10 papers was published on 
Philippine Aedes species (48 in all) contained 
in the NAMRU-2 collection: Knight and 
Ro 2 eboom (1946), Laffoon (1946), Knight 
(1946), Knight and Laffoon (1946), Roze- 
boom (1946), Knight (1947, 1947^, 1947^, 
1948), and Knight and Hull (1951). Be- 
cause of the limitations of space and to 
avoid extensive duplication, the descriptive 
and biological sections and the illustrations 
for all the species treated in the above series 
of papers are omitted from this present work. 
The specimens in the NAMRU-2 collec- 
tion of the remaining Philippine Aedes species 
are here reported for the first time. The bulk 
of the collection used for the previously pub- 
lished treatments is deposited in the National 
Museum and is listed in the distribution sec- 
tion for each species following the heading, 
U.S.N.M. The published records of this 
material are not included under "Literature 
Record" of distribution, except for the sub- 
genus Aedes. The material not previously 
published is given after the heading, R.K.L. 
The names of collectors and the number of 
specimens included have been omitted from 
those records which have been previously 
published. In a few other cases, the number 
of included specimens has been omitted be- 
cause it is no longer available. 
In general, the morphological descriptive 
terminology employed here is that used and 
explained by Carpenter, Middlekauff, and 
Chamberlain (1946). However, several de- 
partures from this terminology have been 
made. Chief among these are the following: 
the treatment of the paratergite as a pleural 
sclerite instead of a mesonotal structure, 
where it motphologically belongs (this has 
been done for convenience since it is more 
easily noted when an examination of the 
pleural sclerites is being made) ; the use of the 
term meteusternum for the area designated 
by them as the metameron; the use of 
Marshall’s (1938: 40) larval head hair numer- 
ical nomenclature; and the listing of the larval 
eighth abdominal segment hairs in dorsal- 
ventral order with Arabic numerals. 
Subgeneric synonyms are given only in 
those cases where they were first applied to 
a species that occurs in the Philippines. The 
subgeneric descriptions apply specifically 
only to Philippine species. 
Unless othefwise stated, the data included 
under bionomics are those gathered in the 
formulation of the NAMRU-2 collection. 
The figures in this paper were not drawn 
to scale. Illustrations marked with the initials 
WBH were made by the junior author. 
A dagger (f) in the synonymy sections 
denotes types that have been examined by us. 
The following abbreviations are used in the 
descriptions. Adult: apn — anterior pronotal 
lobe; ppn — posterior pronotal lobe. Larva: 
isc — inner or upper caudal hair of the anal 
segment; osc — outer or lower caudal hair of 
anal segment; Ih — lateral hair on anal plate. 
The following abbreviations are used in 
the species distribution sections to denote the 
present locations of specimens examined. 
A.N.S.P. — Academy of Natural Sciences of 
Philadelphia; C.A.S. — California Academy of 
Sciences; U.S.N.M. — U. S. National Mu- 
seum; B.M. — British Museum (Natural His- 
tory); C.C.— Cornell University; R.K.L. — 
specimens from the collection of Naval 
Medical Research Unit No. 2 on which 
nothing has been previously published and 
which are now deposited in the U. S. National 
Museum, the Johns Hopkins University, the 
Knight collection, the California Academy of 
Sciences, and the British Museum. 
To obtain uniformity in the listing of the 
distribution of each species, the Gazetteer to 
Maps of the Ehilippine Islands, second edition, 
1944, published by the Army Map Service, 
Corps of Engineers, U. S. War Department, 
has been used for the spelling of all place 
names. The islands of Luzon, Cebu, Panay, 
Negros, and Mindanao are divided into 
provinces, and in nearly every case distribu-
