144 Orthorrhapha brachycera. 



Female. I do not know tlie feinale; it is described as liaving 

 the yellow tlioracic stripes luuch broader tlian in tlie male, tlie case, 

 I tiiink, being the same as m the two sexes of scolopacea. 



Length 9.5 — 10 mm. 



This species is of a soinewhat robust shape; it and the preceding 

 one are easily distinguished from the other species by the divided 

 stigma; when the inner part of the stigma is indistinct, as in the 

 present species, the species is still distinguished by tlie small stigma 

 from the species with undivlded stigma. The species maculata and 

 immaculata are easily distinguished from one another by the colour 

 of thorax and abdomen. 



L. immaculata is very rare in Denmark, only two specimens have 

 been taken many years ago, and no particular locaiity is recorded. 



Geographical distribution: — Northern and middle Em-ope, but 

 rare in the iiorthern parts; its northern limit lies in southern Sweden.
