 specimen on a tag, the head, caudal legs and a fore wing on a slide.

 Arkansas (T. S. Wilson).

Hahrocytus cerealellce (Ashmead). 



Parasite of Sitotroga cerealella, Philadelphia, Pennsylvania. 



Types. — Catalogue No. 6115, U. S. National Museum, tags 

 and a slide. 



Catolaccus anthononii Ashmead has 3- and 4-dentate- mandibles 

 but I am not sure how many ring-joints, apparently three (but 

 female type has lost antenute). 



The species obscuripes has an obscure cross-carina on the 

 scutellum near apex, despite what I have said in the Annals of the 

 Entomological Society of America, IX, 1916, p. 292. It does not 

 belong here (tridentate mandibles).
