OMPHALENTEDON new geuiis. 

 Pcmale: — Like Mesiocharis Foerster Ijut Ihe auteiniaj with three ring-joints. 

 1. OMPHALENTEDON LONGUS new species. Genotj^je. 



Female: — Length, 1.50 mm. Abdomen conical, somewhat longer than the thorax. 



Dark metallic teenons green, the broad fore wings hyaline, the legs (except cephalic 

 ■coxffi) and the scape white. Petiole of abdomen brownish, wider than. long. Thorax very 

 coarsely polygonally reticulate, the lines raised, finer on cephalic scutum, the pronotum scaly.

 which occupies somewhat less than a fourth of the surface. Postmarginal and stigmal veins 

 short, subequal. Hind tibial spur normal. Parapsidal furrows along caudal half, obtuse. 

 AxillfE much advanced but only about half projects cephalad of scutellum. Pronotum trans- 

 verse-linear. Marginal vein twice the length of the submarginal. Pedicel subequal to funicle 1 

 which is one and a half times longer than wide, slightly longer than 2, 3 still shorter; terminal

 I'.ind leg on a slide. 



MESTOCHAROMVIA new genus. 



Genotype, Mestocharis lividiis Girault. Includes Mestocharis veternosus and silv^ensis. 

 Each species bears a paired median carina on the propodeum; lividus has a middle short one 

 at base, also sUvensis but the short carina is longer and sjjlit. In ixtemosus, the short third 

 middle carina is absent, the propodeum at meson witli two separated carinEe. Types re-examined.

 diverging only at apex.

 tip, the tarsi white, their distal joint black. Also the hairs on scutum are black, funicles 2-4 

 are quadrate and subequal, each much larger than the pedicel, 1 only slightly longer than wide, 

 dub distinctly longer tlian any of the funicle joints. Type antennie of Entedonomyia 

 compared.
