Species medium in size. 



Male (pi. 47, fig. 1). — Length 2 mm. Praesciitiim same as in 

 female. Pronotal spots minute, not visible from above. 



Propodeal groove may be complete or incomplete; propodeum 

 either granulose or rugose. 



Petiole about one and one-half times as long as broad. 



Legs black except at knees, which are testaceous; front tibiae are 

 fuscous. 



Antennae : Fiagellum and pedicel shorter than head and thorax 

 combined; hairs on first joint or flagellum as long as the last joint 

 of antennae; end of apical joint of antennae has a conspicuous broad 

 and long spur; scape is distinctly broadest near the distal extemity 

 and is one-half as broad as long exclusive of base; 2 to 4 annulations 

 at the articulation of all flagellar joints except at the distal extremity 

 of the penultimate where there are none. Scape nearly twice as 

 broad as first flagellar joint. 



Type-locality. — La Fayette, Indiana. 



Type.— Cut. No. 21755, U. S. N. M. 



Described from many females and males reared in cages under 

 artificial conditions and from specimens reared from stems of blue 

 grass collected at Eichmond and La Fayette, Indiana, by the senior 

 writer. 



This species inhabits the center of the stem and has been reared 

 only from the seed stalks of blue grass {Poa pratensis). It probably 

 occurs wherever blue grass grows normally. Males normally occur. 



HARMOLITA DACTYI.ICOLA, new species. 



Plate 40, fig. 7 ; plate 43, fig. 7 ; plate 45, fig. 16 ; plate 48, fig. 4. 



Female. — Length 3.0 mm. Praescutum reticulately lineolate with 

 numerous broad, irregular, shallow impressions, rarely without them. 

 Pronotal spots large, occupying one-half to two-thirds anterior 

 dorsal margin of prothorax. 



Propodeum with a distinct, continuous, medium, longitudinal, 

 margined groove, which is slightly broader posteriorly and contains 

 numerous strong cross rugae ; there is often an indication of a central 

 carina; area laterad of groove usually rugose though sometimes 

 granulose; spiracular carinae usually prominent; fimbria rather 

 prominent. 



Abdomen usually longer than head and thorax combined ; segment 



2 usually longer than 3 and 4 combined ; 3, 4, 5, and 6 subequal, though 



3 usually shortest and 7 usually longest; abdomen quite pointed as 

 seen laterally. 



Legs black except at knees which are testaceous.
