Black, shining ; knees, tibiae and tarsi white ; the apex of posterior 

 tibiae and joints of tarsus fuscous. Antennae as long as the abdomen, 

 moderately thick, a little thickened towards the apex ; the third joint 

 one and three quarter times longer than the fourth ; the rest a little 

 shorter. Wings almost hyaline ; the second cubital cellule is small, 

 with a round horny dot ; the third large, not very much dilated at the 

 apex ; the radial nervure is received a little past the middle of the third 

 cubital cellule. The saw projects largely, and the blotch is large. $ 

 and (f. 



Ab. Tibiae lined internally with black. 



Length 2 2| lines. 



The colour of the legs, subhyaline wings and the 

 position of the marginal nervure serve to discriminate 

 this common species. 



The larva, according to the observations of Kalten- 

 bach and Yollenhoven, feeds on the leaves of Ranun- 

 culus rep ens and acris. It is sea green throughout, 

 except on the head which is pale-yellow on the face, 

 brownish or blackish on the vertex. When fully grown 

 the head is shining black. Sometimes, according to 

 Vollenhoven, the larva is more or less orange ; and 

 when very young, Kaltenbach says that it is whitish 

 and pilose, the head yellow, with the mouth and eye 

 spots black to brown. It pupates in the earth, where 

 it remains till the following spring. 



A very common species, found all over the country. 



Continental distribution : Sweden, Germany, Hol- 

 land, France, Switzerland, Tyrol, Russia.
