JiRT. 23 FLIES OF THE FAMILY SAPROMYZIDAE MALLOCH 13 



MINETTIA ZEBRA Hendel 



This species appears to me to be the same as tripuncticeps Malloch, 

 and though the description was evidently published prior to that of 

 the latter the fact that Minettia zebra Kertesz was described some 

 years before should bar zehra as the name for the American species 

 and validate tripuncticeps. 



MINETTIA ZEBROIDES Hendel 



The description of this species agrees with picticomis Coquillett 

 in most particulars but the palpi are given as entirely yellow, which 

 is not the case in that species. 



MINETTIA NIGROPUNCTATA, new species 



Male and female. — Pale testaceous yellow, with rather dense Avhit- 

 ish dusting; antennae and palpi yellow, the thorax with eight large 

 black spots as follows : One at suture laterad of each anterior dorso- 

 central bristle, one between each posterior dorsocentral and pre- 

 scutellar acrostichal, one on each side of scutellum occupying the 

 space between the lateral and apical bristle, and one on each meso- 

 pleura at base of the bristle. Abdomen with a black central spot on 

 one or two of the apical tergites. L^gs yellow. Wings yellowish 

 hyaline. Halteres pale. 



Frons a little wider than long, narrowest behind, the orbits hardly 

 differentiated, with the anterior bristle a little shorter than pos- 

 terior and very slightly incurved at tip, postvertical bristles a little 

 shorter than outer verticals, the latter about half as long as inner 

 pair; ocellars very short and hairlike; no surface hairs on frons; 

 face evenly convex; third antennal segment fully twice as long as 

 wide; arista with its longest hairs about half as long as width of 

 third antennal segment; cheek about half as high as eye. Thorax 

 with three pairs of postsutural dorsocentrals, six series of intra- 

 dorsocentral hairs, one pair of long prescutellar acrostichals, the 

 intra-alar quite weak, four long scutellars, and one sternopleural ; 

 scutellum flattened above. Hypopygium of male quite large, lateral 

 exposed portion about as wide and nearly as long as hind femur. 

 Legs normal, all tibiae with a preapical dorsal bristle, fore femur 

 wiSiout anteroventral comb. Inner cross vein a little beyond middle 

 of discal cell; apical section of fourth vein a little over twice as long 

 as preapical; outer cross vein at about its own length from apex of 

 fifth vein.
