280 EMrHYTUS TENER. 



abdomen, tliickish, the third joint nearly a quarter longer than the 

 fourth, the four apical joints become abruptly shorter. Head faintly 

 punctured, as broad as the thorax, densely pilose ; labrum whitish ; 

 thorax smooth, shining, slightly pubescent; scutellum almost opaque, 

 punctured ; cenchri small. Abdomen longer than the head and thorax ; 

 the segmental divisions distinct, sometimes pale; a fourth of the sheath 

 projects ; pilose. Legs whitish-yellow, the posterior femora above, at 

 the sides, and sometimes beneath, black or fuscous black ; extreme base 

 of cox83 and apex of posterior tibise and tarsi more or less fuscous. 

 Wings hyaline or subhyaline; nervures blackish; tr. radial nervure 

 received a little past the middle of the second cellule ; the second 

 recurrent is received a fourth in front of the cubital. Tegulse clear 

 whitish-yellow. Costa fuscous at base. 

 Length 2 3 lines. 



The amount of black on the legs varies. The labrum 

 is as often black as white. 



The larva is stated by Bouche (see Hartig, I.e.) and 

 other authors to feed on Ribes grossularia, and by the 

 first-mentioned author also on willows. It is greyish- 

 green with the three first and three last segments 

 "pomeranzen gelb;" and over the body are three 

 rows of black tubercles, each ending in a bristle. The 

 head is black. It is said by Bouche to pupate in the 

 ground. 



It appears to be not uncommon in many places 

 in the south of England. I have never seen it in 

 Scotland. 



Continental distribution : Sweden, Germany, France, 

 Russia. 



Ob s. Em. gilvipes, King, is probably a variety of grossularice.
