Empria conferta^ n. sp. — Female. Clypcus wiih a median carina, 

 emarginate without a tooth, lobes rounded ; ocellar basin a broad, deep 

 depression extending to the median ocellus, extending between the antennae 

 and not limited by a transverse carina ; the median fovea a rounded pit 

 near the middle of the ocellar basin and connected by a linear furrow with 

 the median ocellus; antennal furrows interrupted; ocellar furrow indicated 

 at middle, the interocellar furrow distinct ; the third segment of the 

 antennae longer than the fourth ; the saw-guides convex above, and below, 

 convexlyj obliquely truncated to a point above at apex ; body black with 

 the collar, tegulse, knees, and front and middle tibiae white. Length, 7 mm.

Empria concreta, n. sp. — Female. Clypeus with a median carina, 

 roundly emarginate with a broad, rounded tooth, lobes broadly rounded ; 

 ocellar basin broad and shallow, reaching the median ocellus, extending 

 nearly to the ventral margin of the antennal fovese, a deeper linear de- 

 pression between the median fovea and the median ocellus, the median 

 fovea a rounded pit situated above a line drawn through the dorsal mar- 

 gin of the antennal foveae ; the antennal furrows interrupted ; the ocellar 

 and interocellar furrows distinct ; the third segment of the antennse longer 

 than the fourth ; the saw-guides straight above, slightly concave below, 

 broadly and somewhat obliquely rounded at apex ; body black with the 

 collar, tegulse, knees, front and middle tibiae and tarsi, tarsi somewhat in- 

 fuscated, white. Length, 8 mm.

 angularly emarginate, the median tooth small and po'nted, lateral lobes 

 angularly rounded ; antennal furrows not interrupted ; the ocellar basin 

 extending from the median ocellus to the middle of the antennal foveae, 

 broad with sloping sides, abruptly elevated at its ventral end, with a fiat, 

 polished shelf at ventral end, a broad crater-like pit in front of the shelf, 

 the median fovea ; ocellar and interocellar furrows distinct ; the third
