Body short, black, shining, inner orbits of the eyes, tegulae, pronotum 

 and abdomen at the sides, yellowish-white ; the third, fifth, and part of 

 sixth abdominal segments above, and legs reddish. Antennae as long 

 as the abdomen, above black, underneath pale testaceous. Head pilose 

 in front. Trochanters yellowish-white; extreme apex of posterior tibiae 

 and tarsi black ; anterior tarsi fuscous. Wings hyaline, costa testaceous ; 

 stigma fuscous; the third cubital cellule not much longer than the 

 second. 



The $ has the face from below the antennae, the belly, and thorax 

 beneath, yellow, with a black mark on the pleurae, and the legs are lined 

 above with black. Sometimes, too, the orbits of the eyes are pale behind. 

 The third cubital cellule seems to be shorter than in the ? . I have one 

 specimen from Braemar with the costa and stigma yellowish -white, and 

 the dorsum of abdomen of the same colour, with a pale brown mark on 

 each segment. The line on the legs too is very narrow. 



Length 3| lines. 



A common species in May and early in June, gene- 

 rally among herbage. I have often seen it on Veronica. 

 I have examined specimens from Clydesdale, Man- 

 chester, Gloucester, Worcester, Glanvilles' Wootton, 

 Devonshire, London district, and Norwich. Stephens 

 records it from Bristol. 



It abounds in Scandinavia, Germany, Holland, 

 France, Switzerland, Hungary, Italy, and Russia.
