Black; the base of antennae and legs yellow-testaceous; the head 

 sometimes piceous, especially on the lower side ; wings hyaline, ciliated, 

 the nervures pallid fuscous. Antennae as long as the body ; in the $ 

 longer, and with joints three to five weakly curved. Radial cellule short, 

 about one-half longer than broad ; the first abscissa of the radius a 

 little more than two- thirds of the length of the second, which is curved ; 

 cubitus obsolete. Pubescence on the median segment and base of abdo- 

 men sparse. 



Length 1 mm. 



The colour of the legs varies ; they may be pure tes- 

 taceous, or they may have the femora infuscated. The 

 head and thorax, again, may be piceous, and the head 

 even reddish. The size of the radial cellule varies 

 slightly, and in some specimens the cubitus is traced 

 to the middle ; further, the base of the abdomen may 

 be reddish. 



Not uncommon. Clydesdale, Gloucestershire.
