Pseudoselandria oxalata, n. sp. — Female: Body black with 

 the following parts whitish ; the two basal segments of the antennae, 

 the labrum, the clypeus, the collar broadly, the tegulae, the upper 

 half or more of the pleurae, the legs, the wings at base, and the 

 abdomen except the saw-guides; median fovea deep, ovate, trans- 

 verse; ocellar basin distinct; third segment of the antennae as long 

 as four and five together; wings clear with the apex of radius , 

 strongly dilated and black. Length 7 mm. 



Habitat. — Wisconsin. Dr. S. Graenicher, collector. 



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

 vein, the medio-cubital cross-vein, the free part of Ro, and the 

 free part of R.4, present; 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 closed at 

 the wing margin and longer than the cell in front of it; media 

 coalesced with the radial sector for a short distance; claws with a 

 minute erect tooth at base; antennae with nine segments. Type, 

 Selandria floridana MacG. 



Closely related to Pseudoselandria, from which it differs in 

 having the first anal cell of the hind wings closed at the wing 

 margin and in having media of the front wings coalesced with 

 radius for a short distance. 



Dolerus tectus, n. sp. — Female: Body black; antenna 1 with 

 the third segment slightly longer than the fourth; head with the 

 vertical furrows obsolete, the front and vertex uniformly convex, 

 the entire surface punctured, the postocellar area more densely 

 and finely punctured than the posterior orbits, the posterior orbits 

 without ridges or depressions, the antennal furrows indicated only 

 near the antennal sockets; the scutellar appendage smooth, without 

 punctures or striations; the median lobe of the mesonotum and the 

 scutellum more closely punctured than the disk of the lateral lobes, 

 the disk of the lateral lobes almost polished ; the pleura closely, 

 coarsely punctured ; the impunctate area of the lateral lobes of the 

 mesonotum extending to the median lobe; the wings fuliginous, 

 the veins and stigma black. ' Length 10 mm.
