of the length of the second joint. Wings greyish tinged; veins blacklsh; 

 the convexity on the last part of the discai vein not darkened; 

 posterior cross-vein in or almost anterior to the middie, the part of 

 the discai vein from the small to the posterior cross-vein distinctly 

 shorter than the second part. Squamulæ yellow, with a brown or 

 blackish fringe. Halteres yellow. 



Female. Epistoma somewhat broader than in the male, yellowish 

 or greyish yellow, palest above. Antennæ with the third joint shorter 

 than in the male, roundish triangular. Legs quite simple; middie 

 tibiæ besides the dorsal bristle with two ventral bristles. 



Length 1,5— 1,7 mm. 



Remarks: I have no doubt that pumilio Zett. and pectinulatus 

 Loew are identical; the specimens in our collection are from Stæger, 

 and probably the determination has been confirmed by Zetterstedt, 

 but they quite agree with Loew's description. Verrall (Entom. 

 Month. Mag. XVI, 1905, 195) already suggests this Identification, but 

 has doubt on account of Zetterstedt's remark: "femoribus posteriori- 

 bus . . . parce ciliatis" ; no doubt this is an error of Zetterstedt. 



C. pumilio is very rare in Denmark; we have only seven specimens, 

 taken by Stæger on Amager many years ago. 



Geographical distribution: — Northern and middie Europe dovvn 

 into Bohemia; towards the north to southern Sweden.
