stigma, the second is oblique and looks like the con- 

 tinuation of the radial nervure. The cubital nervure 

 issues close to the middle of the costa ; it is much 

 longer and narrower than any of the others and at the 

 bottom is curved, loop-shaped, extending to the base 

 of stigma, the first transverse cubital nervure being 

 received at extreme base of first radial cellule and con- 

 tinuous with the radial nervure. The three other 

 cubital cellules are of the normal shape and are angled 

 where the recurrent nervure s are received (in the 

 second and third). The transverse basal nervure is 

 received in the basal third of its cellule ; the transverse 

 median near the end of the lanceolate cellule, the third 

 discoidal cellule being small, six-angled, not much 

 longer than broad.

Fuscous or black; the mouth, palpi, orbits of the eyes, and some 

 irregularly denned spots on thorax, legs and terebra, pale yellow, a line 

 on the femora fuscous ; the sides and ventral surface of abdomen often 

 fuscous; basal joints of antennae fuscous. Wings hyaline, nervures 

 milk white. The transverse basal nervure is received in the first 

 cubital cellule ; the median cellule is much longer than broad, and 

 has the transverse median nervure received close to apical third of 

 cellule. The terebra is slightly curved, and is about as long as the 

 abdomen. 



Length 1 2 lines. 



In the lighter coloured examples the head is pale 

 yellow save two or three marks on front and vertex ; 

 in the darker coloured specimens the vertex and front 

 may be almost entirely black, as may be also the 

 thorax. The other European species differ from
