In my own work with mosquitoes I have already been able to collect 
in hitherto unexplored regions several new species which will be added 
to the already long list, and I feel sure that others will be discovered in the 
material now on hand. Aside from the new species and one new genus, 
forms not indicated by any of the above-mentioned workers as occurring 
in these Islands have been collected, both in Manila and in the southern 
provinces, as will be seen by consulting the bibliography given with each 
species. No claim can be made for completeness of reference in all 
cases, but I believe that, with few exceptions, the works I have cited give 
original descriptions. Where such are not given it was due to lack of 
literature, a feature not always to be avoided in the Antipodes. 
In all, 83 species, subspecies, and varieties, including 7 as new species 
or varieties, are enumerated, embraced in 30 genera in 6 subfamilies. 
The Entomological Collection contains probably 8 as yet unidentified 
species, so that the total number will soon be not far from 95 per cent 
of the number of species found in the United States and, as very little 
work has been done in higher altitudes, the number of species will, 
within the next five years, probably be considerably further increased. 
An interesting and valuable feature of the work being done on Philip- 
pine mosquitoes is the study of their life histories and habits. A great 
diversity of habits, constant for members of a given species, is to be 
found among those so far studied. 
The form described in this paper as Stegomyia fasciata persistans 
Banks is of very great interest. It was at first supposed to be and 
identified as 8. fasciata Fabr., by me, the material in each case having 
been collected rather than reared. Later breedings developed a form so 
unlike the descriptions of S. fasciata Fabr., that doubt arose as to the 
previously identified specimens being S. fasciata Fabr., although Theo- 
bald and Ludlow had both reported S. fasciata Fabr., from almost the 
identical regions where the aberrant form was found. Great care was 
exercised in mounting, and all specimens collected or bred were subjected 
to examination, so that not less than 2,000 have passed beneath my lens. 
Not a single individual was found among the perfect specimens, namely, 
those in which the mesothorax was not in the least denuded, which did 
not display ornamentation quite different from the descriptions of 
S. fasciata Fabr. Unfortunately, it has not been possible for me to exam- 
ine in recent years a specimen of the true S. fasciata Fabr., so that I have 
been obliged to depend upon the very careful descriptions given by 'Theo- 
bald. Because of the character of his descriptions I feel all the more as- 
sured in taking the stand that the form found here, while closely approach- 
ing the type, differs from it sufficiently to be considered a subspecies, the 
constancy of ornamentation in the Philippine form being also a feature 
in favor of separating it as distinct. If this subspecies proves to be 
distinct from S. fasciata Fabr., and provided that 8. fasciata Fabr., can 
not be demonstrated as being in the Islands, the importance of its
