1911. 

 Parafacialia of female about one and one-half times as wide as third 

 antennal joint, slightly narrowing below; those of male slightly widen- 

 ing below. Parafrontalia of female narrowest in middle, a little over 

 half the width of frontalia at that point. Cheeks of male less than 

 one-third eye-height, those of female not much over two-sevenths of 

 same. Palpi of both sexes only faintly thickened apically, not flattened. 

 Both sexes with only one pair of weak ocellars. Front of female 

 distinctly less than eye-width. Only one discal pair of scutellars in 

 both sexes. Penultimate joint of hind tarsi in both sexes hardly or 

 but slightly longer than broad, the tarsal joints in general shortened. 

 Male claws not heavy, strongly curved, slightly longer than last tarsal 

 joint. Vein M] hardly at all or only faintly bent in after origin. 



This genus has from one to two dozen ovarioles in each ovary. The 

 utero vagina is without copulatory vesicles, so far as known. The 

 eggs are large macrotype, subcylindrical, with long petiole. The whole 

 product of both ovaries, being one egg for each ovariole, is apparently 

 deposited at one oviposition period. Puparium white. 



Musca pattoni Austen, M. gihsoni Patton & Cragg, and M. convexi- 

 frons Thoms. appear to belong in this genus, either as typical or as 

 atypical forms.

Differs from Eumusca as follows: Parafacialia of female very broad, 

 equilateral, fully twice as wide as third antennal joint; those of male 

 much narrower above, broadening conspicuously below. Parafrontalia 

 of female in middle fully three-fourths the width of frontalia at same 

 point. Cheeks of male over one-third eye-height, those of female 

 about two-fifths same. Palpi of female much widened and flattened 

 apically, those of male distinctly enlarged at tip but not much flattened. 

 Female with three or four pairs of rather strong ocellar bristles, male 

 with weak ones behind the front pair. Front of female in middle 

 greater than eye- width. Two discal pairs of macrochaetae on scutel- 

 lum. Penultimate joint of male hind tarsi fully twice as long as wide, 

 the tarsal joints in general elongate rather than shortened. Male
