its pale colour, but perhaps the female will show foiir scutellar bristles. 

 — I described it 1. c. as a new species, but since then I have seen the 

 type of iistulata Schmitz and find my species quite identical with it. 

 The chief difference in the description is in the hypopygium, which 

 Schmitz describes without bristles; on the type, however, one long, 

 bristly hair is distinct, it is the hindmost, those anterior to it seem 

 to be smaller than in my specimen; the colour of the frons and the 

 position of the bristles in the lower row in Schmitz's specimen is no 

 doubt due to exsiccation. In my description of pallida the anal tube 

 by a misprint has been cailed reddish yellow instead of whitish yellow; 

 the brownish patch in the fork-cell, mentioned by Schmitz, is less 

 distinct in my specimen.

Male. Frons considerably broader than high, greyish black, dull; 

 inner bristle of lower row in about the same height as the outer and 

 nearer to it than to the upper supraantennal ; supraantennal bristles 

 unequal, the lower about half as large as the upper; the upper supra- 

 antennals as distant as the inner bristles of middle row, or a little 

 more distant, the lower slightly more approximate. Antennæ above 

 ordinary size, black or brownish, arista short-pubescent. Palpi yellow, 

 ordinary, with ordinary bristles. Thorax black, slightly shining, with 

 brownish pubescence. Mesopleura bare. Abdomen black, a little grey- 

 ish, dull, the short hairs a little more visible at the hind margins of 

 the segments and at the sides, at the hind margin of sixth segment a 

 little longer. Hypopygium of medium size, greyish, with short hairs 

 below on the sides, among which one a little longer near the base; 

 there is a dark, flap-like and rounded ventral plate below; anal tube 

 short, yellow. Legs yellowish brown, the front legs a little paler and 

 the hind legs a little darker; hind femora somewhat dilated, with 

 long hairs below the basal half; bristles on hind tibiæ few in number, 

 about 10, somewhat strong. Wings almost colourless, veins brownish 

 yellow, thin veins fme; costa reaching to or nearly to the middle, 1 

 about equal to 2 + 3 and 2 nearly thrice as long as 3; costal cilia 

 moderately short ; fork generally small with the angle somewhat large, 

 but varying; fourth vein curved at its base, for the rest nearly straight. 

 Halteres yellow.
