rinaB are yellow, and the band extends forwards to the vyc ; 

 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 carinse ; the medial band of the 

 wing-covers containing the square black spots is yellowish 

 brown as in *?. macuHpennis, and the extremity is pel- 

 lucid.

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

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 tiie 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 ; ilic wing-covers are brown with 

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