580 A Monograph of Culicidae. 



black with slightly paler nodes, verticillate and internode hairs 

 black ; clypeus black ; proboscis black scaled. 



Thorax shiny black ; prothoracic lobes with flat silvery-white 

 scales ; mesonotum with very long bronzy-black narrow-curved 

 scales ; scutellum black with small flat black scales and with 

 black border-bristles ; metanotum shiny black ; pleurae black 

 with at least one spot of silvery- white scales. 



Abdomen black scaled with five lateral silvery-white spots, 

 the three apical ones very prominent, the two more basal ones 

 rather indistinct ; these spots are more apical than basal and the 

 scales of the apical three apparently stand out from the surface 

 of the body. 



Legs black except the bases, which are testaceous, and two 

 silvery spots on the coxae ; apices of femora and tibiae slightly 

 dilated owing to numerous scales ; the fore femora are somewhat 

 dilated. 



Wings with brown scales, the median of all the veins broad 

 and spatulate, those of the sub-costal, first long vein and also 

 the second except the lower branch double, the rest single ; the 

 lateral vein-scales long and either touching or overlapping, with 

 distinct lateral spines ; border- scales clavate ; fringe long, scales 

 of three series ; first sub-marginal cell longer and wider than the 

 second posterior cell, its base slightly nearer the base of the 

 wing, its stem rather more than half the length of the cell ; stem 

 of the second posterior as long as the cell ; the mid cross- vein 

 and the supernumerary not meeting, the former nearer the apex 

 of the wing, at a slightly acute angle to one another ; posterior 

 cross-vein nearly twice its own length distant from the mid ; the 

 second long vein carried past the marginal cross- vein and scaled 

 past it ; a very pronounced pseudo-vein between the fifth and 

 the sixth. 



Halteres with the testaceous stem, the knob dark, the stem 

 prominently elbowed at the base. 



Length. — 2 mm. 



Time of appearance. — June and October. 



Habitat. — Entebbe. 



Observations. — A series of four females sent by Dr. Aubrey 

 Hodges. They are very distinct and can at once be told by the 

 curious wing scales. No other species occurs in the genus, so 

 that no comparison is needed. Dr. Hodges writes me that he 

 has not seen it elsewhere than at Entebbe, and that it is 

 extremely difficult to capture undamaged, and that it is a blood-
