$8 ILLUSTRATIONS OF TWO NEW SPECIES OF GRASSHOPPERS. 
anterior femora and tibiz, are slightly foliaceous, especially in the 
female; but the hind femora in the males are furnished near the 
tips with a large thick black leaflet on the outside, the hind tibiz 
having two rows of serratures (fig. 1 c), whilst in the female the 
femora have two nearly equal-sized leaflets*, and the tibiz 
are furnished with dilated, dentated portions, which give them a 
very curious appearance (fig. 1 d.) The terminal ventral segment 
of the male is emarginate at the tip, and the anal appendages elon- 
gated, acute, slightly recurved, and furnished within with a strong 
tooth (fig. 1 4.) The ovipositor of the female is broad and bent 
upwards from the base.

This extraordinary insect has the tubercle between the eyes 
developed into a strong acute compressed spine, which with two 
others rising from the pronotum serve to defend the front of the 
body; these horns have a black line extending along them. The 
tegmina are varied with pale and darker green with black patches, 
the veins being elevated and pale-coloured, giving them the 
appearance of being throughout deeply punctured; the same 
appearance is also presented by the exterior apical portion of the 
wings; the anterior femora and tibiz have a few short spines, but 
the hind feet are armed, both within and without, with long and 
acute spines, placed at the distance of about a line apart, which 
decrease in length towards the extremity of the tibize ; these feet 
are marked with bars of green and black, and the spines of the 
femora (which are curved) are black along their front edge. The 
terminal ventral segment is emarginate, and extends beyond the 
two anal appendages, which are incurved, pointed, horny, and 
bifid (fig. 2 a.) 
This fine insect is unique, in the collection of the Rev. F. W. 
Hope, F.R.S., &c. 
The plant represented in this Plate is the charming Rigidella 
flammea of Lindley, from Mexico.
