Female. — Thorax, abdomen, eyes, vertex, occiput and tips of mandibles black; 

 orbits of eyes, entire anteuuse and legs and tegulse yellow, the legs being espe- 

 cially pale. Head minutely sculptured with broad, shallow punctures. esi)ecially 

 abundant and distinct about the ocelli, mandibles tridentate, the terminal tooth 

 being long and pointed ; antennae 14-.jointed, and as long as the entire body, 

 second joint rather long, third and fourth joints of about equal length, the ter- 

 minal joint but little longer than the preceding. Thorax finely, trans%'ersely 

 rugoso-punctate. but not distinctly transversely wrinkled, the parapsidal grooves 

 are very distinct throughout their entii'e course, the two parallel lines from the 

 anterior dorsal margin of the mesonotum are distinct, but short; scutellura 

 coarsely rugose and with two small and approximate and very distinct fovese ; 

 mesothoracic pleurse entirely finely aciculate. Abdomen alwut as broad as long, 

 rounded off (not pointed) posteriorly, the hind thii-d microscopically punctured, 

 ventral valve prominently projecting, the ovipositor sheaths directed upwards 

 and slightly projecting. Legs, including the coxae, pale yellow. Wings hyaline, 

 veins slender and pale, areolet large and nearly obsolete. Length 3 mm. to the

Described from one female bred by the writer from a gall of 

 Acraspis erinacei Walsh at Ames, la., and from thirteen females 

 and two males bred from galls of the same insect sent me by Mr. 

 F. E. Moeser, of Buffalo, N. Y. 



The specimens are all remarkably uniform in size and coloration.
