bristles in the female, wanting in the male; antenn six-sevenths as 
long as the face, third joint one and one-half times as long as the sec- 
ond, rounded at the tip, arista bare, thickened to the middle, the 
penultimate joint slightly longer than broad; sides of tace bare, each 
at narrowest part scarcely one-tenth as wide as the median depres- 
sion; vibrisse strong, situated on a line with front edge of oral 
margin, two or three bristles above each; cheeks one-seventh as wide
