deeply trilobed, the mid lobe with dense flat silvery white scales, 

 the lateral lobes with black flat scales ; there are also a few black ones 

 bordering the posterior edge of the mid lobe, which has Ave brown 

 bristles; metanotum black and shiny; pleurae brown, with silvery 

 white spots. Abdomen narrow, basally broadening to tlie apex, which 

 is 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, with black scales forming 

 two backwardly projecting patches, and with black bristles ; venter 

 witli broadish basal white bands. Legs black, the fore and mid pairs 

 unhanded, the hind with the base and venter of the femora yellowish- 

 white, a small snowy white apical spot ; the metatarsi and first two 

 tarsi with a basal streak of white on the dorsal sides, 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 submarginal longer and narrower than the second posterior, 

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

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

 cross-vein rather more than its own lengtli distant from the mid ; 

 median vein-scales small and spatulate, dark ; lateral ones sliort and 

 rather thick on tlie first and second veins, others longer and thinner. 

 Halteres short and with contorted yellow stems, the knobs broadly 

 expanded, with black scales. Length i mm. 



Time of capture. — June. 



Habitat. — Kuala Lum.pur (in jungle, six miles away). 



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

 first sight a close resemblance to Stegomyia scutellaris, Wlk., 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 Stegonu/ia. 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 the same in any specimen 

 before. 



Genus Danielsia, nov. gen. 



Head covered with small flat scales, with truncated ends, loosely 

 and rather raggedly placed on the head, a few long narrow-curved 

 ones behind, and small upright forked ones with them. Scutellum 

 with small narrow-curved scales ; mesothorax with narrow-curved 

 scales. Palpi short in female, densely scaled ; in the male as loug as 

 the proboscis, the two apical joints short, the apical rather shorter than 

 the penultimate, hair-tufts scanty ; fork-cells rather short. 



A single species only occurs at present. It comes near 

 Macleaya and the former genus, but can at once be told by the 

 narrow-curved scutellar scales, and from Catageiomyia by the 

 long male palpi.
