 anterior margin of front, laterally entirely separated from eye margin. Front dark brown,

 depressed downward and twice as broad as length down middle, posteriorly five-eighths as broad 

 as head width. Frontal hairs absent. Clypeus black. Face greyish brown, laterally black, 

 parallel-sided. Carina high, long, ending before buccal margin, mediolongitudinally pale grey, 

 laterally black. Cheeks greyish white, one-fifth as broad as the greatest diameter of eye. 

 Occiput black. Postverticals very slender. Anterior reclinate orbital just outside proclinate, 

 two-thirds as long as proclinate, more than twice as distant from posterior reclinate as from 

 proclinate ; proclinate slightly shorter than posterior reclinate. Second oral slightly shorter 

 than vibrissa ; succeeding orals gradually shorter.

 distance between anterior pair of dorsocentrals twice distance between anterior and posterior 

 pair. Legs yellowish grey ; femora and fore and mid tibiae brownish black ; fore femur 

 ventrally and apicodorsally with a few long black setae. Preapicals on all legs ; apicals on mid 

 leg. Front metatarsi slightly shorter than next two segments together, mid and hind metatarsi 

 subequal to next two segments together. Wings hyaline, veins yellow ; wing base and tip of 

 second costal section black. ^? 2 +3 nearly straight ; i? 4+s and M parallel. C-index about 1-5 ; 

 4V-index about 20 ; 4C-index about 15 ; 5x-index about 1-5 ; Ac-index about 3-0. Ci-

It is noticeable that the egg-guide resembles that found in the genus Micro- 

 drosophila.

(J, $. Body about 1 mm., velvety black. Head black, as broad as thorax. Eyes dark red, 

 finely pilose. Antennae with second segment dark brown ; third black, one and a half 

 times as long as broad, rounded at tip. Arista with about four dorsal and two ventral long 

 branches and a large terminal fork. Palpus black, with a strong apical and a weaker ventral 

 setae. Ocellar triangle convex, large, black, somewhat grey pollinose. Periorbit dark greyish 

 black, pollinose, anteriorly somewhat broadened and ending near the anterior margin of front. 

 Front velvety black, anterior margin deeply concave, anteriorly narrowing and slightly narrower 

 than length down middle, posteriorly half as broad as head width. Clypeus black, somewhat 

 glossy blue. Face greyish black, medially somewhat broadened. Carina dark brown, long, 

 high, almost reaching buccal margin. Cheeks narrow, black, grey pollinose, about one-seventh 

 as broad as the greatest diameter of eye. Occiput black. Postverticals moderate in size. 

 Mouth-parts greyish brown. Anterior reclinate orbital just outside proclinate, twice as distant 

 from posterior reclinate as from proclinate, slightly shorter than proclinate, which is about two- 

 fifths as long as posterior reclinate. Vibrissae strong ; second oral weak, half as long as vibrissae ; 

 other orals shorter. 



Mesonotum deep black, somewhat glossy, setigerous. Scutellum velvety black. Thoracic 

 pleura black. Two humerals. Prescutellars five times as long as anterior dorsocentrals. Aero-
