Tribe MELANOMYmi. 

 PHASIOPHYTO, new genus. 



Genotype. — PJiasiopliyto fumifera, new species. 



General Melanomyine characters. Facialia about half as wide as 

 parafacialia. Arista rather thickly short-plumose. Eyes practically 

 bare. Frontals stopping at base of antennae. Parafacialia wide; 

 inner half bare, outer half thickly set with bristles. Cheeks over one- 

 fourth eye length. One lateral scuttelar; two sternopleurals, postin- 

 traalars, preacrostichals, and postacrostichals; three postsuturals; 

 long decussate apical scutellar pair. Third vein bristled only at base, 

 others bare. Apical cell nearly closed in tip. Hind crossvein nearer 

 to small crossvein. No median marginals on first segment, but a pair 

 on second, marginal row on last two segments. 



PHASIOPHYTO FUMIFERA, new species. 



Length, 5 mm. One male, Rio Charape, Jaen Province, Peru, 4,500 

 feet, September 13, 1911 (C. H. T. Townsend). 



Soft blackish-brown. Frontalia and bare parts of face with testa- 

 ceous or lighter tinge. No distinct thoracic vittae. Abdomen largely 

 brownish-golden pollinose; the bases of last three segments silvery, 

 widening laterally. Wings fuscous on costa. Tegulae fuscous. 



Type.—Csit. No. 22253, U.S.N.M. 



Tribe OEMITNI. 

 ORMIA BREVICORNIS, new species. 



Length, 7.5 mm. One female, Texas (Belfrage). 



Differs from punctata Robineau-Desvoidy as follows: Third anten- 

 nal joint no longer than second. Front almost equal to eye width. 

 Parafacialia wider. Vibrissae weak and indistinct. Cheek grooves 

 reaching half way up face. Facial plate narrowed on lower half. 

 Cheeks nearly two-fifths eye length. 



The first-stage maggot has the cephalic spine-clusters, but the 

 spines are arranged in a longitudinal series; in punctata they are 

 arranged in a transverse series. 



Type.— Cat. No. 22268, U.S.N.M. 



ORMIA DOMINICANA, new species. 



Length, 6 mm. Three females, San Francisco Mountains, Santo 

 Domingo, September, 1905 (A. Busck). 



Differs from punctata Robineau-Desvoidy in the face widening 

 evenly from front, the inner border of eyes thus straight in front 

 view, the parafacialia thus noticeably widening above. 



The first-stage maggot has one large talon or spine on each side of 

 head, instead of a cluster. 



Type.— C&t. No. 22269, U.S.N.M.
