ORTHOPTERA. 



" Both the elytra, or wing-cases, and the posterior part of the thorax, are of a 

 fine delicate green ; the anterior part of the thorax yellowish brown ; with the head 

 and body still paler. The wing-cases, as usual in this tribe, bear no very distant 

 resemblance to the leaves of certain plants, not only in colour, but also in the outline, 

 and still more so in the conformation of the nerves which arise and branch off towards 

 the extremities, exactly in the same manner as the nerves arise, and ramify, from the 

 mid-rib in the leaves of the far greater number of plants. One peculiarity in the 

 structure of the elytra in our new species deserves remark : the scutel, or rather that 

 portion of the wing-case on the left side that folds over the back when the creature 

 is at rest, is of a much stronger texture than any other part of the insect, except the 

 thorax, and serves as an external covering or defence to the corresponding lobe of 

 the other wing-case, which is of a more delicate nature, consisting only of a thin and 

 pellucid membrane, the surface of which is hyaline or glassy. The wings are re- 

 markably tender, of a whitish colour, and semitransparent." — Donovan.
