base. Black; line on clypeus, angles of pronotiim, tegulse, spot on 

 mesepisternum, scutellum, posterior half of propodeum, apical margins 

 of five apical dorsal segments, trochanters, bases of femora (the pos- 

 terior ones broadly), four anterior tibiae and tarsi beneath, base of 

 posterior tibiae, and post-basitarsis yellow; wings hyaline, slightly 

 brownish, iridescent; venation pale brown. 



The paratype differs in having a yellow spot on the labrum.

MACROPHYA MELANOTA, new species. 



Superficially like M. albomaculata Norton, but that species, as 

 determmed by MacGillivray, has the antennal furrows present, while 

 melanota has the antennal furrows obsolete. Related to tibiator 

 Norton, especially varieties of this species with black hind tibiae. 

 From the typical form of tibiator it may be separated by the following 

 characters: Postocellar area nearly quadrate, and bounded by fine 

 furrows; antennae cylindrical and more slender, with joints less dis- 

 tinctly defined; clypeus, postocellar area entu'ely, anterior femora 

 beneath, propodeum and hind tibiae black; coxae pale apically and 

 without a pale lateral spot on the hind pair; sheath sharply obliquely 

 truncate. 



Female. — Length 8 mm. 



Northern Illinois. One female from the Ashmead collection.

MACROPHYA NIGRISTIGMA, new species. 



Allied to MacropJiya formosa (Klug), but may at once be separated 

 by the black stigma and other characters. From Macrophya zabriskei 

 Rohwer it may be separated by the yellow scape. 



Female. — Length 10 mm. Labrum broadly rounded apically; 

 clypeus deeply, squarely emarginate, lobes truncate; antennal 

 foveae narrow, elongate; antennal furrows obsolete; head below the 

 supraorbital line confluently punctured; above the supraorbital Ime 

 shinmg, with scattered punctures; postocellar area not defined; 

 postocellar line much shorter than ocellocular line; third antennal 

 joint about one-third longer than the fourth; stigma rather narrow, 

 rounded below, obliquely truncate at apex; sheath nearly parallel- 

 sided, obtusely rounded at apex. Black; clypeus, labrum, spot oil 

 mandibles, scape, angles of pronotum, tegulae, apex of prescutum, 

 scutellum, scutellar lobe, minute spot on mesepisternum, propodeum 

 and terminal dorsal segment, yellow; legs yellow, bases of four ante- 

 rior coxae, spot on hind coxae, apex of hind femora, base and apex of
