Eurytomocharis eragrostidis Howard. 



Congeneric with minuta but the venation as in typical 

 Eurytoma; marginal vein a third longer than the stigmal, the 

 latter somewhat shorter than the postmarginal. A \aricoloured 

 species. Funicle 1 one-third longer than wide, wider distad, 

 2 quadrate. T\pe examined. 



Eurytomocharis triodii Howard. 



A species of Eurytoma. X'enaiion as in E. eragroslidis. Funicle 

 joints subequal, each a)iout two-thirds longer than wide, subequal 

 to club 1. Abdomen lanceolate, its petiole very short. Propodeal

Eurytoma minnesota, new species. 



Female — Ditters from illirwisensis in having the median 

 channel of the propodeum doul)le for nearly the proximal half, 

 the former is somewhat more slender and the abdominal petiole 

 is longer, approaching quadrate. The species solenozophericB 

 Ashmead has the abdominal petiole very short, the abdomen 

 subsessile and the median channel of the propodeum is bifoveate 

 at base only.. The three species are very close. The species 

 solenozophericp, however, has the median basin of propodeum 

 distinct caudad, there bounded by a V-shaped carina. Petiole 

 finely scaly, tricarinate. 



The male has the cephalic tibiie more or less black; funicle 

 o-jointed. 



Described from two males, six females reared from quack,
