^videning in same proportion, face at lower angle of eyes about one and 

 three-fourths times eye-width. Frontal bristles more or less decus- 

 sate, female with two proclinate orbitals, and two reclinate ones 

 inside them, strong pair of proclinate ocellar bristles. Parafacials 

 wide, about one-half width of space between crests of facialia, the 

 latter bristly from one-third to nearly one-half way up, - Oral margin 

 cut off but quite produced, the vibriss^e distinctly removed from it. 

 Cheeks nearly one-fourth eye-height, eyes descending a httle short of 

 vibrissse. Proboscis short and fleshy; palpi elongate, bowed, slightly 

 thickened apically. Second antennal joint moderately short; the 

 third in female elongate and narrow, giving a hnear effect ; arista long, 

 bare, thickened on basal one-third. 



Three sternopleural bristles, the middle one weaker and approxi- 

 mated to the anterior. Four postsutural bristles. Three strong 

 lateral pairs of scutellar bristles, the posterior longest; a long but weak 

 decussate apical pair, a slightly shorter weak discal pan*. First seg- 

 ment without median macrochsetfe; second Avith a median discal short 

 pair and a median marginal long pair, sometimes an adventitious 

 weak bristle or two between these two pairs; third segment with a 

 discal short pair and a marginal row of eight strong ones, not counting 

 others below; anal segment with a discal row of shorter ones and a 

 marginal row. Hind tibiae with a sparse row of short bristles, a longer 

 one or two among them. Claws of female about as long as last tarsal 

 joint, appearing moderately elongate. Wings moderately elongate; 

 anal cell very narrowly to widely open, sometimes appearing almost 

 closed, ending well before mngtip. No wrinkle or stump at bend of 

 fourth vein, hind crossvein nearer to bend. 



Reproductive habit, leaf-oviposition ; uterus long and slender, with 

 yellow honeycomb-reticulate microtype eggs. 



Type-species. — Ophirosturmia cincta Townsend. 



Tliis genus bears some afEnity with Pseudatractocera, but second 

 antennal joint is not very elongate, tliird joint is about three or more 

 times as long as second, faciaha are ciliate on lower two-fifths, and 

 discal bristles are present on intermediate abdominal segments. 

 It bears a strong resemblance to Siphosturmia in coloration of 

 abdomen, latter being fasciate black and white with yellowish-red 

 anal segment.
