Mitchell at Victoria, Texas, from pecan probably on an Acroi 

 species; at Dallas, Texas, under Hunter No. 1486; and in Massa- 

 chusetts from lepidopterous larvae on cranberry. Ashmead's type 

 was reared from Euryptcliia saligneana in District of Columbia. 



PRISTOMEEUS (PKISTOMERUS) MINUTUS, new species. 



Female. — Length, 4 mm.; antennae, 3 mm.; ovipositor, 2 mm. 



Much smaller than agilis and differing otherwise principally by 

 the key characters. Compared with the above description of oceUatus 

 differs as follows: eyes broader, not a third longer than wide; malar 

 space nearly as long as basal width of mandible; clypeus rounded at 

 apex; diameter of lateral ocellus and postocellar line subequal; 

 mesoscutum subpolished and densely punctate throughout; meso- 

 pleurum polished, punctate below, the striation perpendicular; 

 areola broad; hind femur hardly stout, tooth very small and far 

 beyond middle, denticles absent; second tergite distinctly shorter 

 than first, nearly three times as long as wide at base; thu'd not 

 striate at base. 



Head piceous, orbits ferrugmous; clypeus, mandibles, and scape 

 and pedicel yellowish; thorax, mcluding propodeum, largely piceous, 

 pronotum, mesoscutum, and scutellum ferruginous; wmgs hyaline, 

 venation brown; legs stramineous, hind femur dull testaceous, 

 tibia fuscoue at base and apex, tarsal jomts fuscous, pale at base; 

 abdomen largely reddish piceous, paler at sides. 



Type locality. — Los Angeles County, California. 



Type.— C&t. No. 22864, U.S.N.M. 



Described from one female reared by D. W. Coquillett from a 

 cecidomyid gall on juniper.

PRiSTOMERUS (NEOPRiSTOMERlIS) MELLEUS, new species. 



Female. — Length, 6 mm.; antennae, 4.5 mm.; ovipositor, 2.5 mm. 



Head broader than long; face slightly narrower than frons, pol- 

 ished, sparsely punctate; clypeus strongly rounded at apex, malar 

 space slightly longer than basal width of mandible, ocelli distmctly 

 narrower than either ocell-ocular or postocellar Ime; temples convex, 

 opaque, as is also the vertex; mesoscutum opaque, coarsely punctate; 

 pronotum polished, punctate in lower angle; mesopleura, metapleura, 

 and propodeum punctate, last striate posteriorly; areola hexagonal, 

 slightly more than one and one-half tunes as long as wide, costulae at 

 about anterior two-fifths ; stigma rather narrow, barely half as wide 

 as long; hind femur slender, tooth at apical third, denticles obsolete, 

 longer calcarium more than a third as long as basitarsus; abdomen 

 polished; second tergite much shorter than first, about two and one- 

 half times as long as wide at base, only slightly wider at apex.
