a marginal row on third, discal row on anal segment beMnd which are 

 apical bristles and hairs. Legs blackish, the tibise faintly tinged with 

 reddish-brown, the front femora pollinose on outer surface. Wings 

 clear, tegulae whitish.

Deposits white maggots, probably on host. 



Genus AZYGOBOTHRIA Townsend. 



AzygobothriaTowyssEi^D, Ann. Ent. Soc. Amer., vol. 4, 1911, p. 142. 



General approximation to external characters of Sturmia. Eyes 

 quite thickly clothed Avith short hairs, wliich however, are inconspicu- 

 ous and easily overlooked. Front of female at vertex hardly width of 

 one eye, at anternisB greater than eye- width; face of female occupies 

 three-sevenths of head-width below. Facialia ciliate nearly to lowest 

 frontal bristles. Female with two proclinate and two recluiate orbital 

 bristles on each side. A strong proclinate pair of ocellar bristles. 

 Second antennal joint short, third in female four times as long as 

 second. Arista long, thickened on basal half, basal joints incon- 

 spicuous. Cheeks hairy and about one-fourth eye-height. Face 

 gently receding, front not prominent, epistoma subprominent, pro- 

 boscis short and fleshy, palpi elongate and club-shaped. Vibrissse 

 almost on level with oral margin. 



Four sternopleural bristles, the anterior and posterior strongest, the 

 two middle ones situated a little lower. Four postsutural bristles, not 

 counting a fifth one posteriorly a little outside the line of the others. 

 Scutellum with three strong pairs of lateral bristles, a weak apical 

 pair (not decussate in the single specimen showing them), and a 

 stronger widely separated discal pau*. Female with no median bris- 

 tles on first segment, a median marginal pair on second, about ten 

 strong marginal ones on third, weaker ones on anal. Hind tibise of 

 female quite strongly ciliate, with a noticeably longer bristle near 

 middle. Claws of female quite long, about same length as last tarsal 

 joint. Apical cell open, ending well before wingtip. No stump or 

 wrinkle at bend of fourth vein, hind crossvein nearer bend and normal 

 in character. The genus is evidently allied to Achsetoneura. 



Reproductive habit, larviposition ; uterus short strap-like, developing 

 white maggots.
