Descriptions of New Cynipidce 205 



Described from a single female foruierly in the private col- 

 lection of Mr. C. A, Hart and bearing accessions number 547. 

 Taken in southern Illinois. Male unknown. 



Genus Eucoilidea Ashm. 



E. rufipes n. sp. 



Fema'e. — Black; feet, mandibles, and antennae rufous, 

 mesonotum with parapsides converging and uniting in a broad 

 sculptured area; length, 1.8 mm. 



Head: face between eyes and mouth somewhat aciculate, 

 about six aciculations on each side, front smooth, polished, and 

 convex, vertex and occiput smooth and polished, head with 

 scattering gray hairs. Antennae 13-jointed, joints 3 and 4 

 equal in length, gradually incrassate towards the tip, hardly 

 shorter than the body and freely set with short gray hairs. 

 Thorax: mesothorax smooth and polished and along the suture 

 bordering the collar, both dorsally and laterally, is a margin of 

 deep pit-like sculptures ; a row of these sculptures beginning 

 at the outer posterior angle of the mesonotum, runs past the 

 base of the wing and then along the lateral border of the mes- 

 onotum to the place where the parapsidal furrow usually ter- 

 minates ; from this point the row of sculptures extends over 

 the mesonotum in the usual direction of the parapsidal groove 

 and, after running a little more than one half of the distance 

 to the scutellum, suddenly broadens out and, with the similar 

 sculpturing of the other side, forms a broad deeply sculptured 

 area reaching to the scutellum. There is a narrow median car- 

 ina, forked at its posterior extremity, separating this sculptured 

 area of the mesonotum into two equal parts. The sculptured 

 lines divide the smooth surface of the mesothorax into three 

 nearly equal areas. The elevated central portion of the scu- 

 tellum has its large pit or depression centrally located, and there 

 are about six punctures along either lateral border. The edge 

 of this central area extends on all sides in a thin knife-like mar- 

 gin. The depressed border of the scutellum is coarsely rugose 

 and punctate. Abdomen smooth, polished, and without show of 

 hairy girdle at base ; 2i segment occupying the entire surface 

 of the abdomen. Wings fringed and rather coarsely ciliate, 

 radial area closed.
