Pipunculus. 33 



clear, stigma slightly coloured, distinctly longer than next costal 

 segment, middle cross-vein at about the first third of the discai cell 

 or a little beyond. Halteres brownish. 



Lengtti 2,7 mm. 



Female. I possess only the male, and Becker was not sure with 

 regard to the female; he describes {P. sp.? 1. c. 1897, 56, 22; clavatus 

 39, Taf. II, Fig. 7; P. sericeus Q 1. c. 1900, 223, 22) a female, which 

 in all respects is similar to the male, but rather larger, 4 mm; it has 

 a hypopygium of the type present in melanostolus, the basal part 

 tapering evenly into a somewhat long, curved apical part or ovi- 

 positor; the author is inclined to consider it the female of sericeus, 

 it was from the same locality as this latter. In 1921 (1. c.) he declares 

 this female to be the female of the present species. 



P. sericeus is very rare in Denmark, I have taken only one male 

 at Lohals on Langeland ^"/e 1909. 



Geographical distribution: — The species is otherwise known 

 from Transsylvania and Italia. 



Remarks: I consider my determination as sure, only in two 

 points my specimen seems to differ a little from Becker's description, 

 and they are, I think of no consequence; Becker describes the frons 

 as black with a small shining point in the middle, in my specimen 

 the frons is grey, but has the black, shining point; next Becker says 

 that the humeri are brown as the disc, while in my specimen they are 

 a little yellowish; for the rest my specimen is in every point fully 

 agreeing with Becker's description.
