 Qiova-g. Entlei"!. (2), p. 476. 



2 ■ Frons finely rugose, laterally more transversely ; vertex 

 transrugose ; occiput short and rugose, with distinct central 

 apical sulcus ; postei-ior margin of head bordered. First flagellar 

 joint as long as second. Fro- and meso-notum coarsely rugose, 

 neck short and broad. Scutellum only centi-ally smooth. Meso- 

 pleurse dull, densely aciculate, with large, diffuse punctures. 

 Median segment rather smooth, with large punctui-es. Petiole 

 densely trans-striate, shorter than rest of abdomen. Terebra 

 little shorter than body, sheaths black. Hind legs with cox^e 

 coarsely ti-ansrngose ; femora densely and finely alutaceo- 

 punctate, tridentate. 



Black ; head except vertex, base of antennpe, anterior tibiae and 

 all tarsi yellow-red ; anterior femora brown. Wings hyaline, 

 nervures brown ; stigma centrally yellow, tegulee black. 



Length 10 mm. 



Habitat : Stephansort, New Guinea. Type in Hungarian 

 National Museum. 



Szepligetti states that in his F. nova-guineensis, biroi, similis, 

 and nigrijjes the median nervure is prolonged outside the basal 

 nervure. Enderlein (2) gives as the definition of his subgenus 

 Diastephcmus : " external submedian cell entirely wanting, there 

 being at most a tiny remnant of the a.uterior bounding nervure," 

 while, in Feenatopus, this nervure extends to the full extent of an 

 external submedian cell. There might thus be some doubt as to 

 the position of the above species ; as, however, Enderlein places 

 them in Diastephcmus, I follow him,

 femora tridentate, teeth yellov/.
