NEMATUS CURTISPINA. 121 



longer and more rounded in front, not contracted on 

 the outer side of antennae. Only the apex of scu- 

 tellum is black, and the body wants entirely the green 

 tinge. 



Thomson says that the scutellum in the $ is com- 

 pletely black, but in most of my specimens it is only 

 partly so as in the ? . 



The larva has the head pale brown, inclining to 

 orange ; on vertex is a large broad-black spot, and a 

 smaller one goes from the eye to the side ; mouth 

 dark brown. Legs pale green; claws pale brown. 

 Body with the upper half dark green, the sides white. 

 At the base the legs are marked with black, some- 

 times extended into an irregular interrupted band, but 

 faintly indicated over the thoracic legs. Oerci pale 

 red. 



This is a stouter larva than the others in the group. 

 It feeds on Salix pentandra, 8. cinerea, &c. 



Not uncommon. Clydesdale, Kingussie, Wor- 

 cester. 



Continental distribution : Sweden, Germany, France. 



Obs. According to Zaddach (I. c.),N. virescens, Htg., is a synonym of 

 the present species.

Pale greenish -yellow, a mark on vertex (narrowest behind), three 

 large, almost continuous spots on mesonotum ; a mark on scutellum, 

 usually narrowest at base, metanotum and a line of broad tranverse 

 marks on abdomen, black. Antennae scarcely as long as the body, 

 filiform, the basal four or five joints black above, the rest reddish- 

 fuscous, the third joint shorter than fourth. Spurs short, thick, 

 scarcely half the length of cerci. Frontal area long, the lower part 

 ending in a sharp angle, and enclosing the antennal fovea. Middle 

 furrow on vertex not very distinct. Wings hyaline, stigma greenish- 

 white. The apex of hinder tibiae and tarsi fuscous.
