extent the third, in the hind legs the banding is more pro- 

 nounced and extends to the last tarsal, which is dark apically ; 

 fore and mid ungues equal and uniserrate, hind equal and 

 simple. The leg banding is mainly basal, but to some extent 

 involves both sides of the joints — knee spots present. 



Wings with short fork-cells ; the first sub-marginal consider- 

 ably longer and narrower than the second posterior cell, its base 

 nearer the base of the wing, the cell about two and. a half times

the length of the cell ; stem of the second posterior two-thirds 

 the length of the cell ; posterior cross-vein parallel with the mid , 

 a little more than its own length distant from it. 



Halteres thick, with pale stem and fuscous knob. 



Length. — 5 to 5*8 mm. 



<£ . Head scales paler, almost white, with two black patches 

 and dark at the sides, scales and parting just as in J . Palpi 

 deep brown, with a trace of a pale band towards the base, the 

 two apical segments nearly equal and with dense brown hair- 

 tufts, also on the apex of the antepenultimate segment ; pro- 

 boscis black, thin, just a little longer than the palpi. 



Legs as in J ; fore and mid ungues unequal, uniserrate, 

 hind equal and simple. Claspers of the genitalia long with a 

 long thin apical segment, curved up over the bach. 



Length. — 5*5 mm. 



Habitat. — Para, Brazil (Dr. Goeldi). 



Observations. — Described from a perfect <£ and 9 sen t m a 

 collection by Professor Goeldi. 



It is a very marked species, easily told by the median 

 abdominal spots, which form a more or less pronounced median 

 pale line. 



The character of the $ genital claspers turning up also 

 seems characteristic, and the banded legs at once separate it 

 from the somewhat similar albifasciatus of Macquart.
