metanotum pale brown ; pleura pale grey, dull white or pale green, 

 almost nude. Prothoracic lobes small, nude, pale brown. 



Abdomen deep rich chocolate brown to dull brown ; no banding or 

 lateral spots ; border-bristles pale ; venter dull ochreous. 



Legs deep brown, rather long, the coxse and bases of femora grey ; 

 ungues all equal and simple. Wings with the branches of the first 

 sub-marginal cell and the stem with rather long scales, those on the 

 first long vein typical, also the spiny upper costal border ; other lateral 

 vein-scales may appear linear, but when flattened are much broader 

 than in a true Culex ; fork-cells short, the first sub-marginal considerably 

 longer and narrower than the second posterior ; its base nearer the base 

 of the wing, its stem about half the length of the cell ; stem of the 

 second posterior as long or longer than the cell ; mid cross-vein longer 

 than the supernumerary, both united, posterior cross-vein longer than 

 the mid nearly three times its own length distant from it ; fringe dark 

 and dense. 



Halteres with pale stem and fuscous knob. 



Length 3*5 to 4 mm. 



$ Palpi (fig. 4) long thin, longer than the proboscis by the last and 

 nearly half the penultimate segments, with a few spines or hairs only 

 on the two apical segments, the two segments nearly equal, black, 

 remainder of palpi dull yellowish-brown. Fore ungues unequal, uniser- 

 rated ; hind equal and simple ; mid ? 



Antennal organs as figured (fig. 3 a, b.). Wings with short fork- 

 cells, the first sub-marginal considerably longer and narrower than the 

 second posterior ; its base a little nearer the base of the wing, its stem 

 about two-thirds the length of the cell ; stem of the second posterior 

 slightly longer than the cell ; posterior cross-vein longer than the mid, 

 sloping backwards and about two-and-a-half times its own length 

 distant from it ; with the exception of the apical portions of the veins 

 there are no lateral vein scales, only a narrow single row of median 

 ones. Halteres pale with fuscous knob. 



Length 4 mm. 



Habitat : Peradeniya, Ceylon. 



lime of capture : May (1902.) 



Observations. — Described from two <£'s and several 9 's. It generally 

 resembles L K fraudator, Theobald and L. fragilis, Theobald, but the 

 $ can at once be told by the different palpi and antennal organs.
