302 Phoridae. 



distinct hairs at the sides; ventral plate yellowish, roiinded at the 

 end, reaching about to the end of the hypopygium; anal tube some- 

 what small, brownish, a little paler at apex, the apical hairs small. 

 Legs brown or light brownish, front legs a little paler; hind tibiæ 

 only slightly longer than the two first tarsal joints; the hairs below 

 the basal part of hind femora distinct, but not long; bristles on hind 

 tibiæ small and numerous. Wings brownish tinged, veins brown, thin 

 veins somewhat strong, but seventh vein somewhat finer, the third 

 vein rather strong; costa not reaching to the middle, 0,47 of the wing 

 length, costal divisions about as 11 — 5 — 3; costal cilia long, longer 

 than usual; fork longish and the angle acute; fourth vein evenly 

 curved, only slightly more in the basal part. Halteres black or brown 

 to yellowish brown. 



Female. Quite similar to the male; costa a little longer, reaching 

 nearly to the middle. 



Length. 1,6 — 2 mm. 



This species cannot be confused with superciliata Wood which 

 may sometimes have the costa midway between short and long; 

 besides the longer costa and dark halteres also the unequal supra- 

 antennals, the long fork with the acute angle and the larger size 

 distinguish it; especially the fork is characteristical, almost reminding 

 of jiiscinervis. 



Remarks: As I first described the species, I had got it divided 

 into two on account of the halteres, taking a specimen with rather 

 pale halteres for a separate species, and I failed to be aware of the 

 identity; since then I have got more material which pro ves that the 

 halteres vary from blackish to yellowish brown; in all other respects 

 the species are, as also seen from the descriptions, quite agreeing, and 

 the species is for the rest rather characteristic. The new material in- 

 cluded also females which sex was not known hitherto. The name 

 longiciliata under which I first described the species, 1. c. p. 11, I 

 later, 1. c. p. 132 altered to perciliata on account of preoccupation, 

 but I had then already described the species, 1. c. p. 14 as indifferens 

 which name it thus must keep. 



A. indifferens is somewhat rare, but has been taken in several 

 localities; Holte (Th. Mortensen, the author), Bogø south of Sealand, 

 Lohals on Langeland and in Jutland at Hejls and Skamling south of 

 Kolding and at Ry (the author); the dates are V?— Vio in 1917 to 1920.
