Cnephalomyia floridana Townsend. 



Length of body, 11 mm. or over; of wing, scant to full 8 

 mm. Two females, White Springs, Florida; 11 females and 

 19 males, Miami, Florida; October and November, 1908, on 

 flowers of Solidago and on foliage (Townsend). One male, 

 Tifton, Georgia (Morrison-Riley coll.), labeled Spallanzania 

 hesperidarum by Coquillett. 



Dififers in coloring from Acroglossa hesperidarum only in 

 the brassy pollen of front being rather fainter, wholly absent 

 from anterior third or fourth of parafrontals, not reaching 

 base of antennae but falling well short of same in both sexes ; 

 males as a rule without any red on anal segment, females with 

 very narrow rim of dark reddish behind roots of macrochjetae. 

 The black of abdomen shows through the thin covering of 

 pollen producing to the naked eye a soft color effect of dark 

 and tawny-silvery that is peculiar to the species.
