area elevated; median fovea broad, shallow, almost obsolete; ocellar 

 basin oval, not deep; head including postocellar area polished; 

 median and lateral lobes of the mesonotum polished, mesocutellum 

 in part punctate; wings slightly infuscated, stigma and costa yel- 

 lowish infuscated, veins black; saw-guides with dorsal margin 

 straight, ventral margin convex, converging toward distal end, dis- 

 tal end truncately rounded. Length 7 mm. 



Habitat: Ithaca, New York. No. 129-1-2. 



The male differs only in having the clypeus more deeply emar- 

 ginate, limited on each side by slight projections and the bottom 

 of the emargination straight. 



Unitaxonus rumicis spec. nov. 



Female. Body black with the following parts rufous: lab rum, 

 mandibles, distal two-thirds to one-half of coxge, trochanters, fe- 

 mora, tibia^, protarsi, mesotarsi, and abdominal segments two to 

 four ; third segment of antennae nearly twice as long as the fourth ; 

 clypeus only slightly emarginate; median fovea wanting; ocellar 

 basin oval, deep, surrounding median ocellus, limited at ventral 

 end by a round flat area between antacorise ; head polished ; median 

 and lateral lobes of mesonotum polished; mesopleurae densely seta- 

 ceous aud finely punctate; wings infuscated, costa pale, veins and 

 stigma black; saw-guides with margins straight and distal end 

 broadly bluntly rounded. Length 8 mm. 



Habitat: Ithaca, New York. No. 91-2-1. 



The length of the third antennal segment and the shape of the 

 saw-guides will separate this species from repentinus MacG. De- 

 scribed from a single specimen in poor condition. 



Empria cetaria sp. nov. 



Female. Body black with the following parts white: labrum, 

 tegulse, and legs except proximal two-thirds of coxae, distal third of

 head polished, densely setaceous, punctate with numerous fine cal- 

 ices; clypeus flat, squarely shallowly emarginate, lateral projecting 

 angles bluntly pointed ; ocellar basin a shallow shield-shaped depres- 

 sion including median ocellus; median fovea very minute, slight 

 pit-like depression at ventral end of ocellar basin; antennis with
