INSECUTOR INSCITI^ MENSTRUUS 127 



Differs from Xanthomelanodes as follows : Apical cell nar- 

 rowed, closed in tip of wing. Apical crossvein bent in, not 

 parallel with hind crossvein. Face and front narrower, para- 

 facials narrower. Third antennal joint longer. Palpi longer 

 and larger. Macrochsetse absent from middle of first abdominal 

 segment in both sexes, and from anal segment of female. 



Erythrophasia, new genus. 



Genotype, Erythrophasia atripennis, new species. 



Differs from Trichiopoda as follows : Female. Face much 

 narrower, only a little widened from front. Frontalia but 

 slightly widened anteriorly, the front at base of antennae only 

 a little wider than at vertex. Facialia not broadened, no bris- 

 tles below vibrissae. Abdomen cylindrical, not widened at base. 

 Lobes of ovipositor terminating in a sharp clawlike spur. Hind 

 tibiae not ciliate. Wings narrow, apical cell petiolate, cubitus 

 arcuate, hind crossvein farther from cubitus. 



In general appearance and characters the genus agrees closely 

 with Xanthomelanodes , with which it is very apt to be con- 

 fused. It differs in the wider head, lack of macrochsetse on 

 abdomen, wider frontalia, and the spurlike termination of ovi- 

 positor lobes. 



Erythrophasia atripennis, new species. 



Length of body, 8 mm. ; of wing, G mm. One female. White 

 Springs, Florida, October 17, 1908, on flowers of Buthamia sp. 

 (Mrs. C. H. T. Townsend). It is practically certain that this 

 is the long-lost Phasia atripennis Say, 1829, Compl. Writ., II, 

 363-4 (nee Wahlbergia atripennis Towns., 1891, Proc. Ent. Soc. 

 Wash., II, 145-6, which see above). 



Differs from Say's description of Phasia atripennis only as 

 follows : The face, paraf rontals, and orbits are silvery-white 

 pollinose, laid over a pale yellowish ground-color except on 

 occiput, which is blackish. Say's specimen was very probably 

 greased, revealing the ground color and giving a golden sheen 

 to the pollen, as is the case at this date on the left side of head 

 of present specimen. The very narrow hind margins of all 

 the abdominal segments are distinctly whitish pollinose. The
