4. B. berolinensis Villen. 



1912. Villen. Ann. Mus. Nat. Hung. X, 612,4. — ?/S. pygmaea Zett. 1845. 

 Dipt. Scand. IV, 1302, 24 et 1859. XIII, 6181, 24. 



Male. Again tliis species is similar to the foregoing, but the 

 frons is broader, about one third of the eye or more, and the palpi 

 are red in apical part. Third abdominal segment has no bristles. 

 Hind femora witli only anterodorsal and anteroventral bristles but 

 no anterior. Claws on anterior tarsi shorter than in gladiatrix. The 

 genitalia I have not been able to examine, according to the descrip- 

 tion the forceps is a little shorter than in the foregoing, broad at 

 base, granulated, with the end a little hook-formed. 



Female. Like the two foregoing females of more yellowish 

 colour with weak markings. Palpi more yellow than in male. Sixth 

 abdominal segment quite hidden. Ovipositor small with the apex 

 protruding backwards and downwards. 



Length 4 — 5,5 mm. 



Villeneuve has suggested tliat the species is identical with pijg- 

 maea Zett., and Ringdahl, who has seen Zetterstedt's type, has com- 

 municated to me, that he can confirm this opinion. 



B. berolinensis is rare in Denmark, I possess only one specimen, 

 a male, taken in Dyrehaven on -^/g (the author). The above descrip- 

 tion of the female is drawn from a Swedish specimen. 



Geographical distribution: — Northern and middle Europe 

 down into France; towards the north to middle Sweden.

 broader in female, only slightly protruding. Jowls about one fourth 

 or third of the height of the eye; cheeks not very broad. In male
