15. A. pygmaeoides n. sp. $. 
Frons a little broader than high, black, a little greyish and 
with an indication of being shining; inner bristle of lower row be- 
low the outer and about in the middle between it and thé upper 
supraantennal; supraantennals unequal, the lower-considerably smal¬ 
ler than the upper; the upper supraantennals approximated, a little 
nearer together than the inner bristles of middle row, the lower a 
little more approximated. Antennæ brownish black, arista short- 
pubescent. Palpi yellow. Thorax black, very slightly shining. Meso- 
pleura bare. Abdomen black, duli. Legs yellowish brown, hind 
femora a little dark at apex, with a little longish hairs below the 
basal half; bristles on hind tibiæ distinet and of medium size, 
not numerous. Wings colourless, veins yellowish; costa about 0,34 
of the wing-length, costal divisions about as 11—3 — 2; third vein 
a little strong; costal cilia moderately short, fourth vein very slightly 
and evenly curved, a little interrupted at the base. Halteres yel¬ 
low. — Length 1,5 mm. 
Ry in Jutland 12 /i 1918 (the author), one female. 
This species evidently belongs to the pygmaea -group and is very 
near pygmaea and brachyneura ; from the latter the colour distin- 
guishes it and from pygmaea it is distinguished by the normal ab- 
dominal tergites; I have described this single female as it is evid- 
enlly an undescribed species, but how the male will be distin¬ 
guished from pygmaea I cannot say, unless the darkest, clear- 
winged forms of pygmaea should prove to belong to the present 
species.

The original description of this species is given in common 
terms, the immense inerease in the number of species in later 
years makes it impossible to identify the species after the description, 
1 shall therefore here give some supplements: The species belongs 
to the group with two scutellar bristles, uniform bristles on meso- 
pleura, a long and long ciliated costa and dilated front tarsi. As 
said in the description the species is black with black antennæ.
