Description. — A rather laijie unifonuly blackish l)rown 

 species with soft whitish pubescence laterally, and covering 

 the whole ventral surface. 



Male. — Eyes approximate; ocellar triangle with some 

 rather long- black hairs; antennal triangle black, with black 

 hairs and some light tomentum, especially along the eye mar- 

 gins. The face is covered with shining white tomentum that 

 is slightly stained yellow near the antennae, which have 

 abundant black hairs on the basal segment. The dorsal sur- 

 face of the thorax is covei-ed with bi'own tomentum; thei'e 

 are traces of white tomentum at the sides. About six 

 bristles are situated anteriorly to the insertion of the wings, 

 and a group of about six more are on the postalar callus, 

 but the presence and number of these bristles depend largely 

 upon the condition of the specimen. The abdomen is uniform- 

 ly brown, with a tx'ace of a margin of white hairs at the apex 

 of each segment, but more intensified on the first. The legs 

 are reddish brown. The wings are uniformly suffused brown 

 with reddish brown costal margin and veins. There are only 

 two submarginal cells, and the upper branch of the cubital 

 vein has a stump-formed appendix. 



Female. — The characters of the female are similar to 

 those of the male, from which it difi'ers in the sepai'ated eyes; 

 the front is similar to the frontal triangle of the male in col- 

 our and pubescence, and the face shows more yellow, tending 

 to golden, hairs below the antennze. 



Levf/th : 12-15 mm. 



Hub.— New South Wales; Blackheath, November, 19 It), 

 and Como, October, 1921. 



Type. — The type, according to White's manuscript, is 

 not to be found in the British Museum, and presumably it is 

 lost. The specimens described above, a pair in my own col- 

 lection, were taken at Blackheath on the 21st November, 

 1919. There are four other pairs taken in copula, and i fur- 

 ther seventeen specimens in the series examined. 



Note. — This species is similar to C. extensa, but differs 

 in having white instead of yellow pubescence; the loop of 

 the radial vein is not quite so long, and the presence of the 

 appendix on the cubital vein will also serve as a more or less 

 reliable distinguishing character. From C. dacena and C. 

 sobria, it differs in the absence of the cross vein between the 

 radial and cubital veins as well as in colour and other de- 

 tails.
