rinse are yellow, and the band extends forwards to the eye ; 

 the band behind the eye is quite narrow, and the sides be- 

 low it green, like the parts above, and the triangular dash 

 of black upon the top of the pronotum at the hinder an- 

 gles is much narrower than there, on account of the lesser 

 divergence of the lateral carinae ; the medial band of the 

 wing-covers containing the square black spots is yellowish 

 brown as in S. maculipennis, and the extremity is pel- 

 lucid.

Vertex of the head slightly swollen at anterior border of 

 the eye, but rounded as is also the apex ; edges not up- 

 turned ; foveolae only indicated by a very faint, scarcely 

 perceptible depression ; sides of the pronotum rather sud- 

 denly constricted in the middle, the lateral carinae broader 

 than the sharp medial one ; hind border of pronotum 

 slightly rounded ; wing-covers of the length of the abdo- 

 men. 



Brown, generally dark ; face yellowish brown, blotched 

 with black ; a narrow black band extends from the tip of the 

 vertex along each side, extending back on to the pronotum 

 by the side of the lateral carinae to the posterior border, 

 widening upon the pronotum ; the usual black band be- 

 hind the eye is rather broad, and there is another similar 

 one on the pronotum farther down the side, with a yellow- 

 ish streak between them ; the wing-covers are brown with 

 a medial row of darker spots ; the legs are brownish, with 

 the extremity of the hind femora and the base of the hind 

 tibise darker.
