54 Syrphidae. 



but generally black-haired at the incisures. Legs a little shorter-haired 

 than in the male, and femora and tibiæ all white-haired. Wings a 

 little more tinged, sometimes especially about the middle. Squamulæ 

 paler, whitish. 



Length 5,5 — 6,5 mm. 



Verrall's description, at all events of the male, is not quite agreeing 

 with my specimen ; it seems to differ by the almost quite black-haired

epistoma, the more long-haired abdomen and somewhat fringed anterior 

 tibiæ ; also the figure of the antennæ shows a rather short third joint, 

 though in the text it is said to be about one and a half times 

 longer than deep. One might almost be inclined to suggest, that it is 

 my Fenium duhiiim (se below) which Verrall has had before him. 



P. Heringi seems to be rare in Denmark, I only know three 

 specimens; Copenhagen in a garden (the author), and two specimens 

 from earlier time; the only date is ^^/e. The specimens are all females, 

 but according to Zetterstedt Stæger had sent him a male [geniculata] ; 

 it may however be noted that Zetterstedt may well have mixed the 

 species with Penimn duhium described below. 



Geographical distribution:— All Europe; towards the north to 

 southern Sweden; further it is recorded from the Ganarian Islands. 



4. Penium Phil. 



This genus is in most respects quite agreeing with PipizeUa. The 

 species are medium-sized or small, black or æneous. Frons in the male 

 arched, and in none of the sexes protruding; in the female it has no 

 transverse depression such as in Cnemodon. Antennæ somewhat short, 

 third joint short or somewhat elongated. Male genitalia rather large, 

 the ninth segment with its appendages stretching long in under the 

 venter. Legs as in PipizeUa. Wings with the upper marginal cross-
