Aphiochaeta. 331 



As my male specimen is in no good condition the above descrip- 

 tion is partly drawn from a Diitch specimen, kindly sent me from 

 Pater Schmitz. 



A. involiita seems to be very rare in Denmark, I possess only 

 one pair, a female taken at Ry ^^Z? 1918 (the aiithor) and a male taken 

 at Hulsig ^V? 1921 (Th. Mortensen); further I possess a female, which 

 I have taken on Bogø V? 1917, but it is less typical and has yellow 

 legs, so tliat perhaps it does not belong here. 



Geographical distribution: — Besides in Denmark occurring in 

 England and, according to the above, in Holland. 



81. A. manicatella Lundbk. 



1920. Lundbk. Vidensk. Meddel, fra Dansk naturh. Foren. 71, 132. — 

 A. suhmanicata Lundbk. (nec Malloch, Ent. News 1914) 1. c. 71, 20, 23. 



Male. Frons considerably broader than higli, greyish, diill; inner 

 bristle of lower row a little below the outer and slightly nearer to it 

 than to the upper snpraantennal ; supraantennal bristles nearly equal, 

 the upper in the same distance from each other as the inner bristles 

 of middle row and the lower direct below the upper, not more ap- 

 proximate (in one female specimen the upper supraantennals are a 

 little more distant than the lower). Antennæ small, black or brownish 

 black, arista distinctly pubescent. Thorax black, very slightly shining, 

 with brownish pubescence. Mesopleura witli uniform bristles. Abdomen 

 black, dull, the short hairs almost only visible at the hind margins 

 of the segments and very slightly longer on sixth segment. Hypopy- 

 gium small and withdrawn, there is a couple of small bristles down- 

 wards on the sides; ventral plate yellowish, flap-like, rounded at the 

 end; anal tube small, dirty yellowish. Legs brownish, front legs paler; 

 the front tarsi somewhat stout, metatarsus only a little narrower 

 than tibiæ, the other joints more slender; hind femora with long hairs 

 below the basal part; bristles on hind tibiæ distinct though not large, 

 about 12 in number. Wing white, a little milky, thick veins brown 

 the others colourless; costa 0,40 of the wing-length, costal divisions 

 about as 9 — 4 — 3; costal cilia long; fourth vein evenly curved. Halteres 

 black. 



Female. Similar; front tarsi of the same shape and the hairs 

 below hind femora likewise long. 



Length 1,2 to nearly 1,5 mm. 



The stout front tarsi remind one of involuta, but this species has 

 other costal divisions.
