NEW GENERA AND SPECIES OF TENTIIREDINID.-fc: 

 A FAMILY OF HYMENOPTERA.* 



BY ALEX. D. MACGILLIVRAY, UNIVERSITY OF ILLINOIS. URBANA, ILL. 



The following descriptions of new genera and species are a 

 continuation of those of a previous paper: 



Empria costata, n. sp. — Female: Body black with the collar, 

 teguhe, the legs beyond the knees for the most part, and the caudal 

 margin of the abdominal segments, white; head with the post- 

 ocellar area uniformly convex, the interocellar and ocellar furrows 

 distinct; the clypeus tridentate, the median tooth as long as the 

 lateral angles, broadly, shallowly emarginate at middle, the lateral 

 angles rounded, the median ridge low, not reaching the dorsal 

 margin of the clypeus; the third segment of the antennae longer 

 than the fourth; the sawguides slightly convex above, broadly, 

 convexly rounded below at apex to a blunt point above, wings 

 hyaline. Length 6 mm. 



Habitat. — New Haven, Connecticut. B. H. Walden, collector. 



This species falls near cava, from which it differs in lacking 

 the broad, convexly rounded median ridge of the clypeus and from 

 calda in having the clypeus tridentate with the median tooth as 

 long as the lateral angles. 



Pseudoselandria, n. gen. — Front wings with the radial cross- 

 vein, the media-cubital cross-vein, the free part of Rs, and the free 

 part of R 4 present; the free part of the second anal vein wanting; 

 media not strongly angularly bent, the first abscissa of cubitus 

 distinctly longer than the free part of M4; costa dilated at apex; 

 hind wings with the first anal cell distinctly petiolate and shorter 

 than the cell in front of it; media separating from radius distinctly 

 before the origin of the radial sector; claws with a minute erect 

 tooth at base; antennae with nine segments. Type Pseudoselandria 

 oxalata, n. sp. 



Related to the genus Selandria, from which it differs in that 

 the claws have an erect tooth at middle and the media is not angu- 

 larly bent at base.
