Genus LEUCOMYIA. 



no v. gen. 



Head covered with narrow-curved scales and some irregular 

 flat lateral ones and upright forked scales ; mesothorax and 

 scutellum and prothoracic lobes with narrow-curved scales ; a tuft 

 of elongated, outstanding flat scales at the root of the wings ; 

 palpi short in the $ , composed of five segments, the apical one 

 minute, the penultimate longer than the rest, antepenultimate 

 broadest, the two basal ones small ; long in the $ , composed of 

 three segments, acuminate, slight hair-tufts. Male genitalia 

 with very broad flat short claspers ; harpes 

 short and blunt ending in spines ; harpogones 

 blunt and also short. 



Wings with rather dense broad linear 

 lateral vein-scales ; median vein-scales rather 

 large and spatulate, especially prominent over 

 the first, third, and fourth veins and the fifth, 

 not on the branches of first fork-cell. 



The structure of the male genitalia bring 

 it near both Janihinosoma and Grabhamia. It 

 may be related to the latter but is very 

 distinct from the former genus. 



Two well marked species come in this 

 genus, namely, Culex gelidus, Theobald, and the new species 

 described here — the former is taken as the type of the genus. 

 The wing scaling is accentuated in plegepennis. 



Culex quasigelidus, Theob. (Mono. Culicid. III. p. 181) also 

 probably comes here. 



The species all have densely silvery-grey scaled areas in front 

 of the mesonotum.

 segment, which is acuminate, the penultimate segment shorter 

 than the antepenultimate, both segments with long brown hairs 

 on each side, but not forming noticeable tufts, a series of long 

 hairs also on one side of the slightly swollen apex of the ante- 

 penultimate segment. Antennae normal, grey with brown verti-
