anteriorly, meeting as faint impressions in a shallow pit about two- 

 thirds the distance from the anterior edge of the mesonotum; mese- 

 pisternum with a clearlj^ defined intumescence in the upper anterior 

 angle, this apparent intumescence being really due to an arcuate 

 impression of the mesepisternum which forms the boundary between 

 the anterior superior and posterior inferior portions of the mesepi- 

 sternum: labrum conspicuous, the mandibles when flexed not meet- 

 ing the edge of the clypeus.

Type. — Konigliche Zoologische Museum, Berlin. 



Female. — Length, 2 mm.; black and polished; face indistinctly 

 punctured, clypeus castaneous, mandibles stramineous with dark 

 tips, malar line a little shorter than the mandibles are wide at base, 

 scape and pedicel stramineous, flagel 31-jointed, aU joints at least 

 nearly three times as long as thick and dark brown excepting the 

 sixteenth to nineteenth joints, inclusive, which are whitish; occipital 

 carina interrupted above, the space between the upper ends of the 

 carinae approximately at least twice as wide as the distance between 

 the lateral ocelli, oceUi nearly equidistant, the lateral ocelli distinctly 

 nearer to each other than to the nearest point on the eye margin; 

 pronotal furrow interrupted medially, laterally foveolate, tegulse, 

 wing base, and legs, including the coxae stramineous, except the 

 hind tarsi which are dark, wings with a brownish tinge, costa dark 

 brown, stigma and veins brownish stramineous; propodeum with a 

 median longitudinal carina, longitudinal carinae wanting between the 

 basal transverse carina and the base of the propodeum, lateral longi- 

 tudinal carinae virtually complete, basal and apical transverse cari- 

 nae present, petiolarea with a transverse carina; metapleurae wrinkled; 

 first dorsal segment narrower at base than at apex, a little longer 

 than wide at apex, longitudinally striate, brownish stramineous, sec- 

 ond segment stramineous, abdomen stramineous apicaUy and ven-

Paratopotype. — June 7, K. Fiebrig S. V. 



Genus EUPHORIDEA Ashmead. 



Euphorideo Ashmead, Proc. U. S. Nat. Mus., vol. 23, 1900, p. 116. 



Type. — EupJioridea claripennis Ashmead, not described. 



This is an undoubted Ancylocentrus Foerster, the type of which is 

 regarded by Marshall as a synonym of the genotype of (Leiophron, 

 Authors not Nees, Halideij^) = Ancylocentrus Foerster .^ 



1 The first species to be included under Leiophron Nees is conspecific with the genotype of Pygostolis 

 Haliday which latter thus becomes a synomyn of the former. 



2 In Foerster's classification (Verb, natur. Ver. preuss. Rheinland, vol. 19, 1862, p. 254), line 3 from the 

 bottom of the page, should read nicht gespalten and the last line gespalten.
