pair directed almost vertically, and a pair of discals directed posteriorly. 
Abdomen short, ovate, first segment black, sub-shining, second segment 
sometimes with brown spot on sides. All segments except the first 
with discal macrochaetz, pollinose at base, and dark reflecting spots on 
the dorsum. Wings hyaline, faintly yellow at base, all veins yellowish. 
Third vein with one to three bristles at the base. First posterior cell 
open, ending well before wing tip. Legs black, middle tibia bearing 
a single stout macrochaeta on the front side near the middle. Hind 
tibia ciliate. 
Male.—Similar to female, differing as follows: Front slightly 
narrower, no orbital bristles, facial ridges usually bristly on at least 
the lower half, third joint of antenne seven times length of second. 
Front pulvilli as long as last tarsal joint. 
Habitat.—College Station, Texas. Described from 10 female 
and 14 male specimens, reared from Loxostege svmilalis Gn., by 
the author, June, 1920. 
This species is readily referable to the genus Evxorista. 
According to Coquillett’s table—Revis. Tachinid, p. 92—it 
runs out under caption 2, where no provision is made for 
forms with four or more macochaete. In general appearance 
it somewhat resembles futilis O. S., but differs essentially from 
this and its other congeners by the presence of discal 
macrochaete and four sternopleurals. 
Houghia baccharis n. sp. 
Female.—Black, gray pollinose. Front at vertex one and one- 
fourth times as wide as either eye, white pollinose, frontal bristles in 
two rows, descending to the base of the third antennal joint, two pairs 
of orbital bristles, vertical and ocellar bristles robust, the latter directed 
obliquely forward. Frontal vitta rather narrow, opaque, dark-brown, 
extending from base of antennz to ocelli where it is divided and extends 
on either side to the vertex. Facial depression shallow and large, 
not carinate, white pollinose. Antenne as long as face, first two joints 
and base of third yellow, third joint nearly four times as long as second; 
arista black, microscopically pubescent, thickened on basal half, penulti- 
mate joint twice as long as wide. Sides of the face bare, narrow, con- 
colorous with facial depression; facial ridges diverging below, with a 
few bristles above the vibrissee. The latter on a level with oral margin, 
the front border of which is projecting; proboscis ridged, shining, black, 
labella fleshy, yellow; palpi normal, yellow, with only a few short 
bristles. Cheeks white pollinose, with short bristles and stout mac- 
rochaetz, along oral margin; width about one-fifth the eye-height. 
Eyes bare. Thorax gray pollinose, marked with four narrow black 
vittze on dorsal surface, the outer pair widening in front of suture. 
Four postsutural and four sternopleural macrochaete. Scutellum 
black, yellow at the apex, gray pollinose except along the base; three 
pairs of robust marginal macrochaete and a smaller apical pair; dorsal
