scrobes are less uniformly densely pin-punctulate, the face also, the 

 latter with fine cross-striation. Otherwise the same. Thorax with a 

 median sulcus from aboat the center of the scutum to apex of scutel- 

 lum, thinner on the scutellum. Axillae rectangular and face to face 

 (forming a rectangular sclerite between scutum and scutellum). 

 Upper frons with a conspicuous obtuse tubercle on each side of the 

 scrobes; the eyes conical or like mammae. Petiole about thrice 

 longer than wide, coriaceus, its lateral margin carinated. Antennae 

 16-jointed, the club long solid, no ring-joints; funicle joints all 

 wider than long except 1, which is slightly longer than wide; pedicel 

 small, club ovate. Male antennae 11-jointed, the eight funicle joints 

 subequal, twice wider than long, each with a long branch of equal 

 length from the same side, tlie club quadrate, with a smaller branch 

 from its side and another from its apex. Pedicel cup-shaped, longer 

 than any following joint. 



From two males and two females on tags. Tampico, Mexico, 

 June; and a male from Guatemala (Schwarz and Barber). 



Types.— Cht. No. 20863, U.S.N.M., the first four specimens. 



Family EURYTOMIDAE. 



EURYTOMA PHOEBUS, new species. 



Female. — Like vagahunda but the propodeum on each side of the 

 median channel is densely silvery pubescent and the median basin 

 at about distal half is distinctly carinated at lateral margin but this 

 carina is straight not curved at its distal fourth as in vagahunda. 

 Also the tegula is reddish yellow only at apex. Types compared. 



From two females reared from Elymus canadensis May, Elk Point, 

 South Dakota (C. N. Ainslie). 



Types. — Cat. No. 20864, U.S.N.M., the specimens on tags. 



EURYTOMA PHOENIX, new species. 



Female. — Like stigmi Ashmead but at once distinguished in having 

 a distinct abdominal petiole which is over twice longer than wide, 

 as long as the caudal coxae (in stigmi, wider than long) and the 

 median channel of the propodeum is double except at apex (distad) 

 where it terminates in a large, quadrate fovea; also a fourth longer 

 than stigmi. Tibiae yellow, the caudal tibiae nearly so, more or less 

 dark. Abdomen above polished, the petiole densely scaly-punctate. 

 Compared with type of stigmi. Funicle 1 nearly twice longer than 

 wide. The male has the caudal tibia entirely black, the abdominal 

 petiole much longer than the caudal coxa, densely, finely punctate; 

 funicle 5-jointed. 



Described from several males and females taken from an orchid, 

 San Mateo, California (F. Maskew). 



Types.— C&t. No. 20630, U.S.N.M., two males, three females on
