of yellowish ones on their latero- ventral surface ; the lateral projections bearing the 

 usual leaf-like appendage, together with a spine and two hairs ; claspers very large 

 and broad, bent almost at an angle about the middle. Basal parts somewhat 

 resembling those of C. trifilatus, Edw., the harpagones being divided into three 

 untoothed parts. Legs black, tarsi not ringed ; under side of hind femora pale ; 

 small patches of pale ochreous scales at the tips of the femora and of the front and 

 middle tibiae, and a larger patch forming a very distinct pale spot at the tip of the 

 hind tibiae. Claws of the front and middle legs each with a single tooth. Wings 

 with blackish scales, those in the lateral series linear. Base of upper fork-cell nearer 

 the base of the wing than that of the lower ; cross- veins separated by nearly twice 



the length of the lower. 



Halteres brownish.

5. Much resembles the male, apart from sexual differences, but there is practically 

 no sign of a pale ring on the proboscis, even on the under side. There is the usual 

 variation in the abdominal markings, the pale bands sometimes appearing to be absent ;. 

 when present their posterior edges are straight, not rounded. 



Length (without proboscis) about 4-4*5 mm. 



New Hebrides : Port Vila, Zagabe, and at the French Hospital. 



About 60 specimens sent by the French Government to the Imperial Bureau of 

 Entomology, who have presented a series to the British Museum. 



The species differs from C. fatigans in the general black colour and smaller size, 

 in the presence of a more evident pale ring on the proboscis of the male, in the much 

 more distinct pale spot at the tip of the hind tibia, and in the very different male 

 genitalia. The general appearance is suggestive of C. sitiens or C. jepsoni, but the: 

 tarsi and the female proboscis are without pale rings.
