BIOLOGY OF PHILIPPINE CULICID.15. 255 



Theobald has already taken this insect out of Culex and placed it in 

 the genus indicated/" basing his action upon palpal and other characters.

This species, like the other two of Mansonia reported from these 

 Islands, is evidently very obscure in its breeding habits, as nothing has 

 been recorded with reference to it. 



It is fairly common in certain localities in the Philippines, especially 

 near Manila, and it is only a question of time when its breeding places 

 and habits will be known. 



A female captured at night on September 12, 1906, laid eggs on the 

 same night on the edge of the water in the vessel in which she was con- 

 fined. 



Egg: The egg, when recently laid, is pale buff coloi'ed, measures 0.82 milli- 

 meter in length and at one end has a very narrow neck like a bottle. The 

 surface is finely granulated and at the neck end are numerous flat, circular air 

 chambers as shown on Plate X, fig. 3. 



These eggs float horizontally upon the surface of the water, near the side of 

 the vessel. 



The adults of this species have never been found by me to bite or act 

 as if desirous of biting, although the habit possessed by its near relative 

 Mansonia uniformis Theob. is probably to be attributed to this species 

 also.

Nothing is as yet Icnown of the life history of this very abundant 

 species, but some interesting observations have been made concerning the 

 females. They are rather sluggish in flight and are not easily alarmed 

 when seeking to bite a person. These mosquitoes begin to enter dwell- 

 ings which are situated near forests about dusk and may continue to 

 be annoying until 11 or 12 o'clock at night. In the field tliey begin to
