M0.22S1. AREVISIONOFCHALCID-FLIES— PHILLIPS AND EMERY. 443 



Male (pi. 48, fig. 6). — Praescutum same as in female; pronotal 

 spots large, occupying about one-half anterior dorsal margin of 

 prothorax and bright in color. 



Propodeal groove incomplete and propodeum rugose. 



Petiole about two-thirds length of hind coxae and about one and 

 one-half times as long as broad. 



Legs black, except knees, which are testaceous. 



Antennae: Flagellum and pedicel together shorter than head, 

 thorax and petiole combined; hairs on first joint about same length 

 as apical joint of antennae; prominent spur at tip of apical joint 

 which is about four times as long as broad. Scape broadest near 

 center, about twice as broad as first flagellar joint and one-third as 

 broad as long, exclusive of last. Three to five annulations at the ar- 

 ticulation of all flagellar joints except at distal extremity of the first 

 and second when there is one. 



Redescribed from many specimens from cage rearings, from speci- 

 mens reared from rye collected in Indiana, Ohio, and Pennsylvania, 

 and from the type in the United States National Museum. It is also 

 known to occur in California and Illinois. 



This species inhabits the center of the stem and breeds only in rye. 

 It is normally thelyotokous, males very rarely occurring.

Female. — Praescutum reticulately lineolate and withoiit broad im- 

 pressions, except occasionally a few small shallow ones. Pronotal 

 spots large, occupying one-half to two-thirds anterior dorsal margin 

 of prothorax. 



Propodeum with or without groove. If groove is present there are 

 prominent rugae within and it may be either rugose or granulose 

 laterad of groove. Spiracular carinae prominent. If groove is not 

 continuous there is a beginning anteriorly and the prominent carinae 

 curve around to the spiracles. Propodeum may be granulose or ru- 

 gose and may be slightly depressed down center; there is often a 

 median carina. Fimbria rather prominent. 



Abdomen equal to or shorter than head and thorax combined and 

 rather stout. Segment 2 about equals 3 and 4 combined; 3, 4, 5, and 

 6 subequal ; 3 usually shortest and 7 longest. 



Legs black except at knees which are testaceous. 



Antennae: First funicle joint plus ring-joint plainly longer than 

 pedicel ; all the funicle joints distinctly longer than broad ; club joints 

 slightly longer than broad and distinctly broader than funicle. Scape 

 black. Species ranges from very small to medium.
