nosity ; the narrow upper margin and vertical suture of pleurte, as well 

 as the usual patch below wing base, yellowish. Squam*, their fringes and 

 the halteres yellow. Abdomen black, rather glossy, the segments without 

 pale margins ; ovipositor gloss^y black. Legs l^lack, shining, the apices of 

 the femora and the bases of the tibife rather broadly clear yellow. Wings 

 clear, veins V)lack. 



Frons over one third the head wddth ; orbits wdth 4 pairs of bristles, 

 which are not very strong and slightly decrease in strength anteriorly ; 

 antennge rather small, third joint rounded, very slightly pilose ; arista 

 about as long as frons, the pubescence very short ; face slightly receding, 

 concave in profile, the cheek short and not over one sixth as high as eye ; 

 marginal bristles weak, vibrissa not strong. Mesonotum with four pairs 

 of dorso-centrals, the anterior two pairs slightly weaker than the posterior 

 two pairs; 5 — 6 rows of setuhe between the anterior dorso-centrals; no 

 distinguisha))le bristles between the posterior pair of dorso-centrals. Ab- 

 domen elongate, narrow ; surface hairs rather numerous and soft ; hypo- 

 pygium thick, not elongate nor flattened. Legs normal in shape, their 

 surfaces short-haired; no bristles on mid tibife. Costa to the end of fourth 

 vein ; inner cross vein at slightly before the end of first vein, and at very 

 slightly before the middle of the discal cell; veins 8 — 4 divergent on their 

 last sections ; last section of fourth vein about 6 times as long as the penul- 

 timate section ; last section of fifth vein about 1 ^ times as long as the 

 penultimate section. 



Length : 2*25 mm. 



Locality : Kosempo. One specimen, November. 



This species is very closel.y alhed to longifermis Loew, l)ut the color

 wings in hrimnifrons are also not so narow, while the venation also presents 

 some considerable differences.

Female: Black, shining. Prol)Oscis, squamae and their fringes, and 

 the halteres yellow. Legs black, fore til)iae, and all the tarsi, except their 

 apices, yellowish. Wings slightly grayisli, the veins very distinct, black- 

 browii. 



Frons not quite one third the head width, opaque, only the ocellar 

 region and the orbits at the bases of the bristles shining; orbits poorly defined, 

 their inner margin hardly discernable from the central stripe ; four pairs 

 of orl)ital liristles present, which decrease much in length anteriorly, anterior 

 pair only incurved ; orbits without hairs in addition to the bristles, the
