Black ; covered with a short pubescence ; labrum, clypeus, mandibles, 

 orbits of the eyes, save a small bit above the antenna, and legs pale 

 testaceous ; tegulse, the edge of pronotum, a spot on hinder edge of 

 tnesopleura, and the edges of all the abdominal segments, white. The 

 greater part of coxai and femora black. "Wings hyaline; costa and 

 stigma dull testaceous. Antennae not much longer than thorax, the 

 third joint not much longer than fourth, the rest about equal. The 

 second cubital cellule is not much longer than third, and receives the 

 recurrent nervure not far from the middle; the second recurrent is 

 received in the basal third of cellule; transverse median nervure is 

 received a little before middle of cellule. The accessory nervure in 

 hind wing is shortly appendiculated. ? . 



Length 3| lines. 



The larva is dull yellowish- white, yellowish on the 

 head, except the mouth and eye spots which are darker. 

 It lives boring in the pith of rose branches during 

 the second half of May, June, and sometimes on to the 

 first half of July. Towards the middle of April or com- 

 mencement of May the fly appears, and lays her eggs 

 singly in the point of the young branches. The larva 

 soon bores into the pith, whereby the leaves become 

 withered, and then damage is done to the plant. It 

 eats about an inch and a half into the branch, and 

 when it reaches maturity, bores a round hole in the 

 side of its habitation and drops to the ground, where 

 it spins a cocoon. 



Apparently a rare species. The only British locality 

 I know is Oxford where it has been taken by Prof. 

 Westwood. Cf. Van Vollenhoven, I.e.
