received at the base of parastigina ; the transverse median shortly before the 

 middle of the cellule ; cubitus obsolete beyond the 1st transverse cubital ncrvure. 

 The only complete cellules are the 1st cubital and the 1st discoidal ; the trans- 

 verse median nervure is thickened and only present in front, the sul)mediau and 

 the 2nd discoidal cellules being thus not completely separated. Apex of wings 

 ciliated.

OXYURA. 



Z«*lotypa .xaiilliopii;^ sp. nov. 



Black, smooth and shining, the head, thorax and petiole covered with glis- 

 tening white hair; the mandibles and basal two joints of antennae rufous; the 

 legs rufo-testaceous, tinged with yellow; wings hyaline, the nervures dark testa- 

 ceous. 9 • Length 2.5 mm. 



Flagellum of antennae covered with a white i>ile; its first joint fully twice the 

 length of the pedicle, the 1st to 9th distinctly longer than broad, the others not 

 much longer than broad. Angles of collar rounded. Metauotum stoutly keeled 

 in the middle ; the sides bordered by thinner keels. Petiole about 3 times longer 

 than wide, stoutly keeled down the centre and with 2 thinner keels on either 

 side. Marginal vein not half the length of marginal cellule and twice the length 

 of the 1st abcissa of radius. Tegulte rufo-testaceous. Abdomen not much longer 

 than the head and thorax united, sharply pointed at the apex and to a less ex- 

 tent at the base of the 2nd segment.

Epyris varideus sp. nov. 



Black, densely covered with white pubescence, wings hyaline, the nervures 

 whitish testaceous. %, Length 7-8 mm. 



Antennae as long as the thorax and abdomen united, the joints of flagellum 

 clearly separated, densely covered with white pubescence. Head strongly ru- 

 gosely punctured ; the punctures more widely separated and smaller on the ver- 

 tex than on the front, where they run into each other. The keel on the clypeus 

 is dilated and opaque at the apex, which is slightly roundly incised. Mandibles 

 large, curved ; their basal tooth is larger than the others, red, triangular, and 

 does not point, like the others, towai'ds the apex ; the middle pair are the shortest 

 and bluntly rounded ; the apical is long, stout and becomes gradually narrowed 

 to the apex. The mandibles are strongly punctured, the punctures elongate and 

 clearly separated; the outer edge is fringed with long white hair. Pronotum 

 strongly punctured, the punctures round and clearly separated ; the mesonotum 

 is more sparsely and less strongly punctured, and the scutellum still more weakly. 

 Metanotum with a stout keel down the middle ; this is v?"eaker at the base where 

 two keels run into it from the sides; the area thus formed is stoutly striated, the 

 2 inner keels being stouter and widely separated from the thin central keel ; the 

 apical portion of this is closely bordered by striae, which become gradually nar- 

 rowed ; the sides above and the apical slope above are irregularly rugose and 

 thickly covered with white hair. Central depression of propleurae irregularly 

 striated ; the raised lower part with a deep oblique furrow beyond the middle. 

 On the basal half of the mesopleurse is an irregular longitudinal furrow, wide, 

 shallow and striated at the base, narrowed beyond the middle, its apex deep,
