SIPHOSTURMIOPSIS PHYCIODIS CoquiUett 



Sturmia phyciodis C!oqtjiixett, Revis. Tachin., p. 109, 1897. 



Coquillett's description fits the species very well, except that the 

 estimate given of the frontal width, especially that for the male 

 sex, is too narrow. Several additional items not mentioned in the 

 original description are included below: 



Front in male 0.274, in female 0.306, of the head width (10 speci- 

 mens measured in both) ; parafrontals yellow to golden pollinose, 

 sides of face and cheeks paler in color. Thoracic chaetotaxy : Acros- 

 tichal, 3, 3; dorsocentral, 3, 4; intraalar, 3; supraalar, 3; postalar, 

 2; notopleural, 2; presutural, 2; posthumeral, 2; humeral, 4; ptero- 

 pleural, 1 (small) ; sternopleural, 2, 1. Abdomen with a pair of 

 median marginals on first and second segments (small on first) ; 

 third bearing a marginal row of 10 to 12; fourth with a discal row 

 and numerous irregularly placed smaller bristles behind. In the 

 male genitalia the inner forceps are united at the base, divided but 

 not divergent at apex, on the hind side with a large brownish pad 

 thickly covered with soft short pale hairs, rather striking; outer 

 forceps nearly as long as inner pair, yellow at base, moderately 

 slender beyond middle, tips black, acute, curving forward more 

 abruptly than inner ones; fifth sternite reddish, with a broad U- 

 shaped incision, the lobes bearing a few fine black hairs. 



The species ranges from Texas to Ohio and Massachusetts. In 

 my collection there are 86 specimens from College Station, Tex., 

 taken from April to November. The palpi are usually black but 

 sometimes entirely yellow, and there is an occasional specimen with 

 the front wholly gray.
