Two New Parasitic Hymenoptera. 



By William H. Ashmkad. 

 Mr. Otto H. Swezey of the Ohio State University, Columbus, 

 Ohio, has recently bred three interesting hymenopterous para- 

 sites from a homopterous insect Ormenis septeyitrionalis , two of 

 which prove to be new and are described below at his request. 



Family BETHYLID^. 

 Dryinns ormenidis, new species. 

 Female. — Length 4 to 4.5 mm. Black ; clypeus, first five joints of the 

 antennae and the last joint (sometimes the last two joints) pale ferruginous, 

 the scape beneath pale, the intermediate joints black or blackish ; palpi 

 and tarsi pale or yellowish-white ; mandibles, a spot at the sides of the 

 pronotum posteriorly and the legs, except the middle and hind tibiae, 

 which are black or fuscous, rufous, the tarsi pale ; front wings fuscous at 

 base to the basal nervure except at the extreme base, and a broad fuscous 

 band from the apical half of the stigma across the wing but ending before 

 attaining the hind m^irgin, otherwise hyaline, the veins brownish or fus- 

 cous, the base of the stigma whitish ; abdomen shining black, the apical 

 segments especially along the venter, more or less and the sides and apex 

 of the pygidium testaceous.
