abdominal segments showing dusky-golden marmorations in varying 

 lights. Scutellum with two lateral pairs and an apical decussate 

 pair of bristles, all equal; discal pair atrophied and indistinguishable 

 as a rule. First three abdominal segments with a median marginal 

 pair of bristles in both sexes, but those of first very small in female; 

 anal segment with marginal row. Legs black, claws very short in 

 both sexes. Wings clear, tegulae white.

Deposits maggots from a double-sac uterus. 



PH^ENOPSIS, new genus. 



Frontal characters like Metopia and Araba, but eyes thickly hairy. 

 Bend of fourth vein without stump or wrinkle and ending very close 

 to wingtip. Comes from wholly distinct stock from Metopia and 

 allies. The description is made from the male. 



Male front in middle about equal to eye-width, vertex about four- 

 fifths of eye-width. Two pairs of reclinate inner orbital bristles. 

 No oceUar bristles. Frontal bristles descending about to base of third 

 antennal joint, facialia strongly cUiate to lowest f rentals. Facial plate 

 cut off, epistoma not prominent, vibrissae at oral margin. Eyes de- 

 scending almost to vibrissae ; cheeks very narrow, hardly one-eighth of 

 eye-height. Parafacials bare, narrowed below to almost a line. Front 

 conical in profile, face strongly receding. Second antennal joint 

 very short; third in male very long, straight, perfectly equilateral, 

 reaching exactly to oral margin. Arista bare, thickened on basal 

 one-third or so. Male with burnished-silver crescent bounding eye • 

 anteriorly and taking up parafacial and oblique outer anterior part 

 of parafrontal, the two silver crescents almost meeting on the median 

 line over the frontalia. Two sternopleural and tliree postsutural 

 bristles. Tliree lateral scutellar bristles, the middle one much shorter 

 than the others; an erect slightly forwardly-curved apical pair 

 about same length as middle lateral; a weak separated discal pair. 

 Abdomen short subcorneal, first segment without median bristles, 

 second with a -median marginal pair, third with a marginal row, 

 anal with marginal. Hind tibiae of male sparsely delicately pectinate, 

 with a longer bristle near middle. Claws of male very short. Apical 

 cell narrowly open just before wingtip, fourth vein bent at obtuse 

 angle, hind cross vein about in middle between small crossvein and 

 bend of fourth vein. 



Reproductive habit unknown, but judged to be larviposition 

 from a double-sac uterus.
