The larval period probably lasts for ten or twelve days, as a larva in 

 the penultimate stage did not pupate for five days after capture and 

 those in the last stage required three days before pupation. 



Pupa: The pupa of this species resembles those of Stegomyia very closely 

 with the following points of difference: the pinnurte are circular in outline. 

 The seventh abdominal segment has at its postero-lateral margin a 5-parted bristle 

 while the eighth has one of nine parts. 



The urochaette are straight and as long as the pinnurae. The pupal stage lasts 

 about three days. 



Adult: The Philippine specimen corresponds in every respect with the de- 

 scription and drawing '° by Giles, including the basal white patch on the costa. 



HABITS OF THE ADULT. 



Giles states that this mosquito is found in the lower Himalayas, 

 Naini Tal and Bakloh, at 7,000 feet. In the Philippines, the altitude 

 at which they occur is scarcely more than 35 meters. Giles further says. 

 "I found them in a small collection of clean rain water, with some green 

 confervcB in the cemented gutter round a house." " 



I do not know whether these insects are addicted to sucking blood as 

 I was not attacked by them during a week's stay in the region where they 

 breed. All the specimens I obtained are from bred material. 



Theobald ^- remarks that Giles' diagnosis with respect to the banding 

 of the tarsi will not hold good for Australian specimens of the same 

 species. This is likewise the case with Philippine specimens, the white 

 bands involving both the bases and the apices of the joints. 



This species has been found thus far in only a single locality in the 

 Philippines, namely, at the Montalban gorge in the Mariquina Eiver 

 where the dam for the new Manila watenvorks is being constructed.
