IXSfiCUTOR INSCITI^ MENSTRUUS 99 



of head only one-half of antennal axis. Ocellar area very 

 restricted, ocellars quite strong. No proclinate fronto-orbitals. 

 Frontals descending below base of third antennal joint. Facialia 

 with bristles about one-third way up. Very weak discal pair 

 of scutellars, and a hairlike nondecussate short apical pair. 

 Abdominal macrochsetse discal and marginal on last three seg- 

 ments, a median marginal pair on first segment. Legs longer, 

 claws short. Apical cell open, ending immediately before exact 

 wingtip ; cubitus subangular, somewhat rounded ; third vein 

 bristled halfway to small crossvein. Costal spine small, but 

 distinct. At once distinguished from Phytomyptera by the 

 large eyes and small cheeks. The genus is related to Oxynops. 



Elephantocera greenei, new species. 



Length of body, 3 mm. ; of wing, about 3 mm. One male, 

 Wenonah, New Jersey, October 3, 1910 (C. T. Greene). 



Shining brownish-black. Antennas, f rontalia, and palpi dark 

 brown or blackish ; face, cheeks, and para frontals lightly sil- 

 very, the rest of mesoscutum and scutellum more shining but 

 still with thin bloom in certain lights. Abdomen very shining, 

 with faint bloom in oblique light. Legs dark brown or black- 

 ish. Wings clear. Tegula; watery-whitish. 



Holotype, No. 19612, U. S. Nat. Mus. Labeled "Hypostena 

 magnicornis Coq." in Coquillett's hand but evidently never pub- 

 lished. 



Named in honor of Mr. Charles T. Greene. 



Hypertrophomma, new genus. 



Genotype, Hypertrophomma opaca Townsend, new species. 



Female. Form short and broad. At once distinguished from 

 all other muscoid genera known to me by the combination of 

 hypertrophied eyes and almost naked pollinialike p^lpi, the 

 latter character being shared by Lispidea. Head much broader 

 than high, nearly half again as broad as height, its profile sub- 

 semicircular, the vibrissal axis little over one-half the antennal 

 axis. Front and face absolutely equal in width throughout, 

 the vibrissge inserted at extreme edge of the cut-ofT epistoma, 

 the eyes extending exactly from vertex to vibrissal angles, and 

 the antennae inserted just halfway between these two points.
