of the medio-cubital cross-vein and the free part of M3+4 in the 

 front wings and from the Fenusinae, another small group of 

 genera included in the Blennocampides by Konow, by the form 

 of the cell R1+2 of the hind wings. The cell Rj+o being closed 

 throughout and appendiculatc at apex and with vein R3 reaching 

 the margin of the wing distinctly before, the apex in the Scolio- 

 neurinae and the cell R1+2 rounded at apex and open and the 

 vein R3 reaching the margin of the wing at or be^^ond the apex 

 in the Fenusinae. 



Konow^ describes the larvae of five species, all are leaf- 

 miners, two are found on Betula, one on Tilia, one on Getim, and 

 one on Ruhus. In addition to the record of Forbes of Metallus 

 rubi as a leaf-miner on Ruhus as given above, Houghton^ has 

 reported a species on Ruhus from Dela^ware of which specimens 

 were named by the writer as Scolioneura capitalis Nort. 



This subfamily can be differentiated from its congeners as 

 follows : 



SCOLIONEURINAE . 



Head transverse ; the clypeus long, never deeply emarginate ; 

 the antennae with nine segments; the eyes oval in outline, the 

 inner margin straight or uniformly convex, adjacent to the base 

 of the mandibles; front wings with the radial cross- vein, the 

 radio-medial cross- vein usually, and the free part of R^ and R5 

 present; the medio-cubital cross-vein joined to Sca + R + M at or 

 near the origin of the free part of media ; the medio-cubital cross- 

 vein and the free part of M3+4 strongly divergent behind; the 

 free part of M^ + Cui arising at or near the middle of the cell 

 M^; the free part of media and the radial sector straight or 

 gently curved near their origin, not strongly bowed; the medio- 

 cubital cross-vein strongly bowed and joining cubitus about 

 midway between the origin of cubitus and the point of separation 

 of M3 and M^; the hind wings with the cell R1+2 closed and ap- 

 pendiculate at apex, very rarely open; the vein R3 reaching the 

 margin of the wing distinctly before its apex; the free part of 

 R4 and the transverse part of Mj wanting; the second anal cell 

 distinctly petiolate; the claws appendiculately toothed.
