truncated, smoky black, with triangular silvery-white lateral 

 basal spots, the two last segments with basal white bands (under 

 the microscope the lateral spots look pale blue) ; border-bristles 

 black ; the first segment densely black scaled, large, the black 

 scales forming two backwardly-projecting patches and with black 

 bristles ; venter with broadish basal white bands. 



Legs black, the fore and mid pairs unhanded, the hind with 

 the base and underside of femora yellow ish-white, a small snowy- 

 white apical spot • the first, second and third tarsals with a basal 

 streak of white on the upper surface, giving a banded appearance 

 when viewed from above ; ungues all equal and simple. 



Wings with brown-scaled veins, the costa dark, fork-cells 

 small, the first sub-marginal longer and narrower than the 

 second posterior, its stem nearly as long as the cell ; stem of the 

 second posterior as long as the cell ; bases of the fork-cells nearly 

 level ; posterior cross-vein rather more than its own length 

 distant from the mid • median vein scales small and spatulate, 

 dark ; lateral ones short and rather thick on the first and second 

 veins, others longer and thinner. Halteres short and with con- 

 torted yellow stems, the knobs broadly expanded with black scales. 

 Length. — 4 mm. 



Habitat — Kuala Lumpur (Dr. Leicester). 

 Observations. — Described from a single female. It bears, at 

 first sight, a close resemblance to Stegomyia scutellaris, Walker, 

 but the median white thoracic stripe is wider, and the markings 

 of the abdomen and legs are different ; moreover, it cannot be 

 placed in the genus Stegomyia. I am not sure if the narrow 

 waist of the abdomen is natural or due to subsequent contraction 

 in drying. 



The fact that the white abdominal lateral patches appear 

 blue under the microscope and yet not under a hand-lens is 

 peculiar. I have not observed this in any other mosquito.

This common Australian mosquito was provisionally placed 

 in Stegomyia. It is now found to belong to this genus.
