stripe shorter than the caudal median stripe, running to the suture 

 and overspreading the lobes of the scutum, making the sclerite 

 bivittate; scutellum similar in color to the scutum; postnotuin

 stripes. Halteres light yellow, knob not distinctly darker. Legs : 

 coxae traversed by the ventral pleural band; trochanters light 

 yellow ; femora yellow darkened toward the tip ; tibiae and tarsi

 base of cell Sc, at three-fifths of the length of Sc, at origin of Rs; a 

 pale, circular hyaline-centered cloud at the stigma; in center of 

 cell 2nd R<, along cord, in centers of radial cells, at tips of the 

 veins, etc. Venation see fig. g.

 Rhipidia domestica angustifrons subsp. n. 



Like domestica Osten-Sacken, but coloration different. Eyes 

 large, in dried specimens light gray, not black, possibly not normal; 

 vertex between the eyes long and narrow; vertex with a large 

 brown spot in the center. Thorax with the median stripes con- 

 fluent forming a rectangular mark on the caudal portion of the 

 sclerite ; lateral prsescutal stripes very broad, triangular, the usual 

 dots in front of the median blotch are, as a rule, produced into 

 long, narrow streaks, with a third one between them in the middle, 

 making the cephalic half of the prsescutum appear trivittate; 

 lobes of the scutum mostly brown; scutellum very pale. ■ Pleural 

 stripes broader but ill-delimited. Wing, fig. f. 



Male: Length, about 5 mm. ; wing, 6 mm. Female: Length 

 about 6.8 mm.; wing, 6.8 mm.
