Black, the space between the antennse, labrum and clypeus, tegulse 

 and pronotum white ; legs and belly luteous ; the second to fourth 

 joints of hinder tarsi fuscous. Antennse as long as abdomen, filiform, the 

 third and fourth joints subequal; black, reddish underneath and at the 

 apex above ; eyes bordered with testaceous behind. Vertex punctured, 

 pentagonal area well defined, deep, clypeus deeply incised. Mesonotum 

 more deeply punctured than the vertex, scutellum gibbous, more deeply 

 punctured than the mesonotum. Femora stout, calcaria a little more 

 than one-third of the length of metatarsus ; fifth tarsal joint double the 

 length of second ; cerci pale, a little longer than the spurs ; claws bifid. 

 Wings hyaline, stigma pallid yellow, darker at apex, costa pale. 



The (^ has the antennae shorter than the abdomen and thorax, 

 reddish, except at the base above, and the apex of the abdomen is 

 reddish above, sinuated, and with a black broad carina in the middle. 



Length 2 2 lines. 



Similar in coloration to N. vesicator, but narrower, 

 antennse shorter, legs stouter, tarsi shorter compared 

 to tibiae, the fifth joint double the length of second, 

 mesonotum more distinctly punctured, and scutellum 

 more gibbous. 



The amount of luteous colour on thorax and abdomen 

 varies considerably. As with N. rumicis, Continental 

 specimens are much lighter in colour (often for the 

 greater part fulvous) than British. 



If this species be identical with N. pineti, Zad. (which 

 I doubt much, for no mention is made of the punc- 

 tured scutellum, and the $ is said to have the antennae 

 of the length of the whole body), then the larva has 

 been described and figured by Brischke. In habits it 

 agrees with N. xanthogaster, in rolling down more or 

 less the edge of the leaves of Salix alba and S. fragilis. 

 It is bluish-green, darker along the back and white at 

 the junction of the segments. Skin wrinkled, shortly 

 haired. On the two anal segments are a variable
