Family TACHINIDJE 



Tribe Miltogrammini 



Genus Senotainia Macquart 



Senotainia rubriventris Macquart. — The writer retains Senotainia, 

 of which this species is the type, as distinct from Miltogramma in 

 having a more evenly rounded facio- frontal profile, narrower cheeks, 

 bare parafacials, distinct vibrissa?, and longer antennae. 



Miltogramma and Senotainia, with certain other forms yet to be 

 described, constitute a tribe by themselves. The writer can not fol- 

 low Brauer and von Bergenstamm in grouping Metopia, Araba, 

 HilarcUa, etc., with them. The latter genera have the vibrissal 

 angles close to oral margin. 



Tribe Myiophasuxi 

 Genus Myiophasia Brauer and von Bergenstamm 



Myiophasia of Brauer and von Bergenstamm has the eyes bare ; 

 cheeks in female more than one-third eye height in width, in male 

 scarcely one-fourth eye height ; both sexes with short but strong 

 claws, the front claws of male being the only ones that are somewhat 

 longer than last tarsal joint; no macrochsetse on first and second 

 abdominal segments ; arista thickened only at extreme base, second 

 joint short. 



It is hardly possible that the Uruguayan and United States forms 

 that have been referred to this species are identical. Several other 

 well-marked forms have been confused here. M. cenea has the 

 apical cell distinctly though narrowly open 



Myiophasia setigera, sp. nov. 



Differs from M. cenea in having a median marginal pair of macro- 

 chsetae on second abdominal segment in both sexes. Male with rows 

 of hairs on parafacials, female with same rows somewhat less de- 

 veloped. 



Texas, New Mexico, Nevada, Oregon. 



Type.— Cat. No. 11,647, U. S. N. M. (Male, Beulah, New Mex- 

 ico, 8,000 feet, August, Cockerell.)
