half their length, white at the apex, more marked on the hind legs; tibiae all dark; 

 first tarsals have a small basal white spot, larger on the hind legs and the remainder 

 of the forelegs is dark; second tarsals on mid and hind legs with a basal white 

 spot, the remainder of the mid-legs dark; third and fourth joints broadly white 

 banded in the hind legs, the last joint pure white; fore and mid ungues uniserrate. 



Wings clear, brown scaled; the cells long, 1st submarginal longer and slightly 

 narrower than the 2nd posterior, double the length of its petiole, its base inside 

 that of the 2nd posterior; root of the 3rd longitudinal vein and the mid cross- 

 vein about equal in length and meet, posterior cross-vein a little longer, and more 

 than twice its length distant; halteres have the stem light and knob dark. 



Length 6.5 mm. with proboscis, 5.75 mm. without the proboscis. 



Habitat. Mindanao, P. I. Taken. Nov.-Jan. 



In general coloring and marking this suggests some of the 

 Stegomyia, but besides the differences in cephalic scales, those on 

 the scutellum are broader, and round-ended like those found 

 in Kingia. 



For only a few of these insects have the life-habits been worked 

 out in any country, and in the Philippines only M. Liidlowii has 

 been carefully studied. Banks found this Anopheline breeding 

 indifferently in fresh or brackish water, and lately some interest- 

 ing data as to M. indefinita have been received. It has been bred 

 from larvae taken from muddy puddles, quite at variance with 

 our usual idea as to Anopheline habits and the latest collections 

 have the memorandum, "from larvae taken from an open drain, the 

 water comes from bath houses and is of course more or less soapy." 

 So far as I know this is the first instance reported of Anophelines 

 breeding in dirty drain water.
