Phoridae. 



tinged, veins brownish yellow; costa short, aboiit 0,40 of the wing- 

 length; 1 aboiit double 2 + 3; costal cilia short; mediastinal vein 

 not observable; fourth vein shallowly ciirved in its first part and 

 slightly recurved towards apex. Halteres yellow. 



Female. Similar to the male; antennæ almost of the same size; 

 the hairs representing the anterior scutellar bristles generally stronger. 

 Abdomen with the first segment reddish, the next three black, but 

 the second reddish at the sides; the fifth segment orange, brownish 

 on the thinner apical part. Abdomen is of a curious construction; I 

 shall liere describe it as it presents itself for a simple examination, 



as regards the real numbering of the 

 segments referring to the above generic 

 description. The third segment has on 

 eacli side at the front margin a small, flat 

 papilla; the fifth segment is large, but has 

 no chitinized tergite, at the base it has 

 a large, quite membraneous area, which 

 is clear and translucent in the hving 

 specimens; the end of abdomen is long 

 and narrowed, ovipositor-like, the sixth 

 segment has long, erect hairs round the 

 hind margin; the last segment is chi- 

 tinized, its hind margin is obliquely cut 

 and has on each side a small, upwards 

 pointing, black tooth; the segment is 

 clothed with hairs below. 

 Length 1,6 — 2,5 mm, the latter size is for the female with the 

 ovipositor-like end of abdomen included. 



Ph. herolinensis is not rare in Denmark; Dyrehaven, Espergærde 

 (the author), Holte (Th. Mortensen), Geel Skov, Bogø south of Sea- 

 land (the author), on Funen at Veflinge (H. J. Hansen) and in Jutland 

 at Jelling and in Ry Nørreskov (the author); my dates are ^Ve — ^^Z?. 

 My material is taken from 1912 to 1921, but at Veflinge two spec- 

 imens were taken about 1883. The females are found on ulcerating 

 stems of trees and may be seen hovering in swarms round such 

 piaces; the male seems, like the male of fasciata, to be rare, I have 

 taken only three specimens on leaves of bushes. 



Geographical distribution: — Hitherto known only from Den- 

 mark and Germany. 



Remarks: As this species was detected there might, as also
