118 Orthorrhapha brachycera. 



slightly visible and both females having the bands quite similar. 

 Generally the feniale of paniscus is described as having no band on 

 the third segment, e. g. by Scholtz, Schiner and Kowarz (I. c); I have 

 always found this band present, but very narrow, not only in all 

 Danish specimens I have seen but also in specimens from other 

 regions. Though Schiner states in the generic description that the 

 abdomen has seven segments, he yet says with regard to the white 

 or yellow hair tufts at the apex in all three species: "am vorletzten 

 Ringe", but this is not correct as the hair tufts are sitting on the 

 seventh segment.

appearing yellowish on account of the pile; more rarely the pile is 

 more or less black. Head somewhat small, narrower than thorax 

 and situated somewhat downwards at the front end of thorax; it is 

 broader than high, and slightly arched behind. Frons and epistoma 

 somewhat, more or less, protruding. The eyes much narrower than 

 high, more or less reniform, touching in the male, well separated in 

 the female; in the male the upper facets are somewhat larger than 

 the lower. Antennæ inserted near to each other, somewhat above 

 the middle. Jowls small, not or very slightly descending below the 

 eyes. Antennæ five-jointed, the first joint long, cylindrical, the second 

 short, the third the longest, the two last forming a small style the 

 first joint of which is short, the last terminating in a short, bristly 

 part.^ Epistoma somewhat short; the mouth aperture large and 

 looking forwards. There is a distinct oral cone; clypeus broad, chi- 

 tinised above with a prolongation stretching down on each side, but 

 membranous in the middle below and thus horseshoe-shaped. On the 



') Schiner ascribes to Bombylius a thiee-jointed style, perhaps counting the bristly 

 apical part as a joint.
