TETRASTICHOMYIA, new genus (Tetrastichini). 



No groove on. scutmn; one groove (the lateral) on scutellum. 

 Four ring-joints, the third very short, tliree funicle and clnb joints. 

 Petlicel and funicle 1 subolongato. 



Genotype. — Miotropis disiocampae Ashmead. 



PSEUDIGLYPHOMYIA AMERICANA, new species. 



Female. — Length, 1.60 mm. 



Legs and abdomen golden yellow, the head and thorax sanguineous, 

 the wings hyaline, the venation yellow. Variegated with dark 

 metallic green as follows: Ocellar area, upper fourth of occiput, 

 cephalic apex of pronotum, cephalic half of scutum, the area frus- 

 tum-shaped (narrowing caudad, thus leaving the lateral margin more 

 and more) its caudal margin incised obtusely at meson; caudal mar- 

 gin of pronotum rather narrowly, scutellum, propodeum (and the 

 thorax dorsad just laterad of postscutellum and distal scutellum), a 

 moderate stripe across base of abdomen, its caudal margin with a 

 broad obtuse projection at meson, a very broad stripe across beyond 

 middle of the abdomen (equal to over one-third the surface) its 

 margin deeply excavated proximo-laterad at lateral margin and 

 less deeply from lateral margin a little before its caudal end, which 

 is as far from the apex of the abdomen as the proximal margin is 

 from the green stripe at base. Tip of ovipositor valves black. Mid- 

 dle tibia with a rather broad cinctus just below the knee for 

 some little distance. Propodeum with a median carina and no 

 others, the thorax scaly, Scutellum with four bristles which are 

 just laterad of the grooves. Antennae dusky yellow; funicle 1 some- 

 what longer than wide, 2 a little shorter, subequal in length to the 

 pedicel. Nipple of club short, distinct; mandibles 5-dentate. A 

 spot laterad at base of the hind coxae. That portion of the broad 

 stripe of abdomen proximad of the latero-caudal excision passes 

 over the venter. 



Described from one female labeled '^ Clrrospilus flmncincfus Riley, 

 1729, Ohio." 



Type. — Cat. No. 19625, U.S.N.M., the above specimen on a tag, 

 the head, forewing and hind tibiae on a slide. 



ENTEDON OCCIDENTALIS, new species. 



Female. — Length, 3,50 mm. Robust. 



Like E. ligeloviae Ashmead but much more robust, the post-marginal 

 vein is slightly shorter than the stigmal, which is longer than wide, 

 the club lacks the small terminal spine or it is a mere tubercle; 

 funicle 1 is distinctly longer than the pedicel, two and one-half times 

 longer than wide, longer than the club. The abdominal seg- 

 ments after 3 are scaly and 2 is not quite a fourth the length of
