Genotype. — Neometachaeta polita, new species. 



Dijffers from description of Metachaeta as follows: Male only 

 described. Third antennal joint three and one-half times as long as 

 second. Arista thickened on hardly over basal half, basal joints 

 short. Ocellar bristles present. Parafacials about one-fifth as wide 

 as facial plate. Face only shghtly receding, profile of parafacials 

 a httle convex. Cheeks about one-third eye-height or somewhat 

 less. Palpi subcyhndrical, but sUghtly thickened at tip. Proboscis 

 short. Male front at vertex about one and one-third times eye- 

 width. Male with two reclinate inner fronto-orbitals ; two verticals; 

 five or six weak short proclinate outer fronto-orbitals, the posterior 

 one approximated to the posterior inner orbital, the anterior one just 

 in advance of the lowest frontal; five or six downwardly directed 

 facio-orbitals in fine with frontal row, not in exact hne with outer 

 fronto-orbitals. Two sternopleurals and three postsuturals. Scutel- 

 lum with apical pair, and two lateral pairs of which the posterior is 

 very strong. Abdomen elongate-conical. Abdominal macrochae- 

 tae weak ; segments one and two with a lateral, two and three with a 

 median marginal pair, three with a lateral marginal pair, four with 

 marginal row. Claws of male a little shorter than last tarsal joint. 

 Costal spine vestigial. First vein bristly on its proximal half, third 

 bristly nearly to small crossvein. Petiole of apical cell about as long 

 as hind crossvein; latter crooked and nearer to small crossvein than 

 to cubitus, which causes last section of fifth vein to be over half as 

 long as preceding section. Cubitus angular, with pronounced wrinkle ; 

 apical crossvein deeply bent in at base. Third vein ends halfway 

 between second vein and wing tip.
