Aphiochaeta. 243 



Length 2,5 — 3 mm. 



In spite of its similarity to projecta the species will be known 

 by the coloiir, the siipraantennal bristles, the palpi and the hypopy- 

 gium; the description of the coloiir of abdomen by Schmitz shows 

 that the reddish abdomen may be darkened in varioiis ways. — As 

 mentioned under Giraudii I have studied the types to Zetterstedt's 

 hicolor and found that of the four specimens one was Giraudii^ the 

 others simulans. 



A. simulans is rare in Denmark as elsewhere, only two specimens, 

 a male and a female, have been taken, Holte Vs 1918 (Th. Mortensen) 

 and at Hejls south of Kolding V? 1919 (the author). 



Geographical distribution: ■ — Besides in Denmark the species 

 occurs in England, Holland and Germany and towards the north to 

 I middle Sweden.
