QQ [March, 



I describe this species from two males from " Haute Savoie," 

 France, sent to me by M. E. Autran, under tbe name unicolor, H.-S. 



C. GLAUCESCENS, Fieb. 



^ . Abdomen above black, narrowly yellow at the sides ; pygofer above pitch- 

 brown, with the hind margin narrowly yellow, beneath yellow-brown, with the hind 

 margin paler. 



Pygofer : upper and lower notches as in C. dorsata, its outline in the cephalad 

 aspect transversely elliptic, the aperture somewhat hexagonal, the lining and partition 

 whitish, the styles and anal tube brownish-yellow, the hind margin in the lateral 

 aspect somewhat convex. Styles feebly sinuate, gradually narrowed from the base 

 to the apex, where they are slightly produced into a shoi't blunt lobe on the upper- 

 side. Anal tube with the aperture transversely elliptic, the lower part much 

 widened with a wide angular notch reaching from side to side, and bearing at each 

 lower corner a very small, sharp, recurved tooth or hook ; the teeth proper straight, 

 parallel, and directed cephalad in a nearly horizontal position, not visible in the 

 cephalad aspect of the pygofer. 



This species is the unicolor of J. Sahlberg and myself ; I have 

 found it commonly on reeds in coast marshes in Norfolk and Suffolk.

C. PBASiNULA, Fieb. 



(J . Abdomen above black, narrowly yellow at the sides, the hind margin of the 

 last segment narrowly, the hind margin of the pygofer in its upper half, and the 

 anal tube, white ; pygofer beneath and the partition black ; styles pitch-brown, 

 becoming yellow beyond the middle. 



Pygofer : upper and lower notches as in C. dorsata, its outline in the cephalad 

 aspect transversely elliptic, the aperture irregular, owing to the infolding of a 

 bluntly triangular whitish piece on each side of the upper half, the hind margin in 

 the lateral aspect convex. Styles sinuate, gradually narrowed from the base to the 

 apex, where they are truncate. Anal tube with the aperture roundish, the lower 

 part not broader than the sides, the lower corners blunt right angles ; the teeth 

 curved, divergent, and visible in the cephalad aspect of the pygofer.
