Aphiochaeta. 269 



at the sides. Hypopygium of medium size, produced a little downwards 

 and higher than long; it is greyish black, but downwards more brown- 

 ish or blackish red, when fully exposed it is narrowly glossy above 

 just at base; on each side it has about three bristly hairs, one above 

 the other, the lowermost the strongest and sometimes only the latter 

 distinct; ventral plate dusky yellow or brown, broadest at the end 

 and here broadly rounded; anal tube longish, brownish or dusky 

 yellow, palest at apex. Legs yellow or light brownish yellow, hind 

 legs darkest; hind femora below the basal half with a row of short, 

 dense and somewhat strong hairs, densest towards the base; bristles 

 on hind tibiæ of medium size or nearly, about 14 — 16 in number. 

 Wings nearly always rather strongly brownish or greyish brown 

 infuscated, veins strong, brown, also the seventh; costa reaching to 

 the middle or generally beyond, costal divisions about as 14 — 8 — 5; 

 costal cilia moderately long, almost approaching the border between 

 short and long; fork longish, but the angle not large; fourth vein 

 distinctly curved in its basal part and a little S-like at origin. Hal- 

 teres black. 



Female. Similar; hind femora with usual, short, but somewhat 

 dense hairs below. 



Length 1,5 — 2,2 mm. 



I described 1. c. this species under the name of fiiscipennis, be- 

 cause it did not seem to me to agree with fungivora; later on I saw 

 specimens of jiingivora from Wood and I have no doubt that my 

 species is identical with fiingivora; the specimens of jiingivora from 

 Wood which I have seen have three bristly hairs on the sides of 

 hypopygium, Wood has only reckoned the largest of them, the spec- 

 imens have a yellow ventral plate, not black, the anal tube is not 

 specially large and not yellow, but as in my specimens brownish; 

 but Wood' s specimens have the wings rather less tinged than mine, 

 and especially in the female, while my females generally have the 

 wings even as brownish as the males, only a couple of females have 

 them less tinged, this is, however, no doubt only due to variation; 

 Wood says that in the female the first costal division is only 1^/2 

 times longer than the second, but this also is subject to variation 

 and generally the relative lengths are the same as in the male, Finally 

 I shall remark that Wood says "lower side of S hind femora projecting 

 in the middle as in humilis''^ ; under hiimilis he describes this in the 

 following way " about the middle where there is a sort of pro- 

 jecting or shoulder breaking the outline of the under-side"; such
