1921] Reinhard: New Species of Texas Tachinide 331 
Four postsutural and four sternopleural macrochaetz. Scutellum con- 
colorous with thorax, bearing four pairs of long marginal macrochaete, 
the posterior pair reaching base of the third abdominal segment, also 
a shorter apical and discal pair, directed almost horizontally backward, 
the former is cruciate. Abdomen gray pollinose on bases of last three 
segments, narrow apical borders shining black, first segment black, sub- 
shining, with no macrochaete, sides of segments two and three faintly 
yellow, second with a pair of dorsal and lateral marginal macrochaete, 
third with a marginal row, fourth with an irregular row of discals and 
a row of marginals. Wings hyaline. Third vein with a single bristle 
at the base. First posterior cell widely open, terminating far before 
wing tip. Bend of fourth vein decidedly angulated, forming a right 
.angle for some distance before it bends posteriorly, destitute of an 
appendage. Calypteres white. Legs black, middle tibia with three 
bristles on front side near the middle, hind tibia evenly ciliate outwardly. 
Habitat.—College Station, Texas. Described from two 
female specimens collected by the author October 6, 1917, and 
September 18, 1920. 
This fly is very closely allied to Coquillett’s species byralidis 
but differs from the description of that form as follows: Third 
antennal joint twice the length of second; facial ridges bristly 
on lowest one-fifth. Scutellum with four pairs of long marginal 
macrochaetz. Cheeks equal one-fifth the eye-height. The 
four sternopleural macrochaetz will serve to separate it from 
P. argentifrons Coq. 
Exorista loxostegez n. sp. 
Length 4.5 to 6 mm., rather compact, black, thorax and abdomen 
gray pollinose, sub-shining. 
Female.—Head slightly wider than thorax. Front at vertex as wide 
as either eye; sides cinereous pollinose, vitta one-third width of front, 
black, opaque; two pairs of orbital bristles, ocellars present, directed 
obliquely forward; frontal bristles in two rows, descending slightly 
below base of arista. Antenne almost as long as face, second joint 
fuscous, one-fifth the length of third joint, the latter black, covered 
lightly with gray pubescence; arista microscopically pubescent, thick- 
ened on basal half, penultimate joint as broad as long. Facial depres- 
sion, sides of face, and cheeks cinereous pollinose on a fuscous ground. 
Facial ridges bristly on little less than lower half ; vibrissee situated on 
level with front border of oral margin. Palpi black, sometimes yellowish 
at tips, proboscis short, fleshy, labella large, yellow. Eyes distinctly 
hairy. Dorsum of thorax with five black vitte, the inner pair ending 
midway between the suture and base of scutellum, the median vitta 
linear in front of suture, almost as wide as outer pair post-suturally, 
Four postsuturals. Sternopleural macrochaete variable, usually four, 
sometimes with five or six on either side. Scutellum black, sometimes 
faintly yellow on apex, three pairs of marginal macrochaete, an apical
