NO. 2281. A REVISION OF CHALCID-FLIES— PHILLIPS AND EMERY. 445 



Male (pi. 47, fig. 6). — Praescutiim same as in female and bears 

 numerous broad and very shallow impressions. Pronotal spots 

 minute but visible from above. 



Pro})odeal groove complete with numerous cross rugae; rugose 

 laterad of groove. 



Petiole broader than coxae and one and one-half times as long as 

 broad. 



Legs black except at knees which are testaceous; front tibiae fus- 

 cous. 



Antennae: Flagellum and pedicel shorter than head and thorax 

 combined; hairs on first joint of flagellum shorter than apical joint 

 of antennae ; scape distinctly broadest at center and nearly three times 

 as long as broad exclusive of base ; 1 or 2 annulations at each articu- 

 lation of the flagellum; prominent spur at end of apical joint of an- 

 tennae. Scape slightly broader than first flagellar joint. 



Redescribed from five females and two males reared from galls in 

 the stems of blue grass collected at Richmond, Indiana, by the senior 

 writer and from the types in the United States National Museum. It 

 is also recorded from Norman, Illinois, and La Fayette, Indiana, by 

 Dr. L. O. Howard and Prof. F. M. Webster. 



This species makes inconspicuous galls near the base of the seed 

 stalks of blue grass and has been reared only from this grass {Poa 

 pratensis). Males normally occur. 



HARMOLITA POAE. new species. 



Plate 39, fig. 10; plate 43, fig. 6; plate 45, fig. 18; plate 47, fig. 1. 



Female. — Length 2.5 mm. Praescutum reticulately lineolate with 

 occasional small, very shallow impressions. Pronotal spots very 

 small, scarcely visible from above. 



Propodeum with a narrow, deep, continuous, margined, median, 

 longitudinal groove, which has numerous cross rugae; slightly rugose 

 or occasionally granulose laterad of groove. The groove is sometimes 

 shallow and not always well defined; there are sometimes several lon- 

 gitudinal carinae within the groove; spiracular carinae usually promi- 

 nent; fimbria not prominent. 



Abdomen usually distinctly shorter than thorax; segment 2 one- 

 third to one-half as long as the entire abdomen (dorsally) exclusive 

 of segment 1. The greatest vertical diameter of abdomen is some- 

 times at fifth segment; abnoniinal segments vary greatly in length. 



Legs black except at knees and anterior face of front femora which 

 are testaceous. 



Antennae: First funicle plus ring-joint almost twice as long as 

 pedicel; none of funicle or club joints quadrate; flagellar joints about 

 the same width throughout; the club joints are sometimes slightly 

 narrower than the other joints; scape shorter than first funicle joint 

 and pedicel combined ; scape black.
