in length in case of type, thickened just beyond middle, but 

 less swollen than in certain other species of Cadicera, clothed 

 with black hair; proboscis clove-brown; first and second 

 joints of antenna clove-brown, clothed with black hair (third 

 joint missing in case of type). Thorax: dorsum shining, 

 pleurae and pectus dull. Abdomen purplish black, somewhat 

 less shining than dorsum of thorax owing to surface being 

 more coarsely punctured at base of each hair, and also scored 

 with fine transverse striae. Wings : costal cells darker than 

 remainder of surface, anal and axillary cells paler, remaining 

 cells each with a more or less pronounced paler central area 

 or streak ; veins clove-brown. Squama and halteres clove- 

 brown. Legs : front legs and middle tibiae and tarsi dark 

 chestnut-brown.

From all species of Cadicera already described except 

 C. crassipalpis, Macq., C. nigricolor is at once distinguished 

 by its uniform black colour, which is unrelieved by lighter 

 markings of any kind. The less elongate and relatively 

 broader abdomen, and the coloration of the antennae, wings, 

 tibiae, and tarsi differentiate the new species from C. crassi- 

 palpis.

 cream-buff pollinose, smoke-grey on vertex ; antenna relatively 

 short ; thorax yellowish-grey pollinose, dorsum in front with 

 two narrow, admedian, buff-coloured longitudinal stripes, widely

 suture ; abdomen ochraceous-buff at base, dorsum of second to 

 seventh segments inclusive each with a clove-brown transverse 

 band, hind borders of these segments yellowish grey or yellowish 

 pollinose, last three segments and hind borders of third and 

 fourth segments thickly clothed above with ochre-yellow hair ; 

 legs, except middle and hind coxa and tips of tarsi, cinnamon, 

 hind tibia fringed on outer side with ochre-yellow hair. 



Head : frontal callus shining black, transversely elliptical,
