are twice as broad just beyond the base, on a lateral view, as at tip, 

 giving a foliaceous appearance. The foramina of the fore legs are 

 conspicuous, about as large as the terminal joint of the fore tarsi, but 

 are larger at the distal than at the proximal end. All the abdominal 

 appendages are very short. Male only examined.

 backward from the middle of the eyes across the side of the head 

 reddish or pink; labrum white, edged laterally at base with pink; 

 lateral carinae of prothorax with minute and dull denticulations, fol- 

 lowed on sides below by a longitudinal, narrow, brownish stripe. 

 Cerci curved upward and inward, with a slight hook at the tip; pro- 

 cesses of subgenital plate formed of slight extensions of incurved 

 lateral ridges, each with a minute apical bead-like joint. 



Length of prothorax, 7 mm.; breadth of same, 5.75 mm.; length of 

 elytra, 46 mm.; breadth of same, 12.5 mm.; length of hind femora, 

 20.5 mm.; of wings, 49.5 mm.; of cerci, 2.75 mm. 1 cf, Peruvian

7. Orophus peruvianus nov. sp. 



Uniform green, the anal area of the tegmina pale brownish fuscous, 

 the tips of the femora and of the tibiae, and the tarsi infuscated. 

 Tubercle of vertex very full and rounded, the sides abrupt only at 

 the tip, with a scarcely perceptible longitudinal carina above, and a 

 distinct, but not conspicuous, transverse carina between the antennae. 

 Pronotum only one-third longer than broad, the hind edge regularly 

 convex, and furnished with a row of very short hairs ; posterior half 

 of the disc flat, with distinct and abrupt lateral carinas ; anterior half 

 convex, with rounded carinae ; a pair of distant impressed lines cross 

 either side of the middle transversely, curving backward as they ap- 

 proach the median line, which they do not reach but fall into a slight 

 shallow double pit a little behind the centre. Tegmina subfusiform, 

 broadest before the middle, the apex produced somewhat but 

 rounded, the inner edge scarcely convex. Wings extending some- 

 what beyond the tegmina in repose. Spines of tibiae black-tipped. 

 Cerci clavate, and bearing at the tip an appressed, triangular, black- 

 pointed tooth, directed inward ; subgenital plate produced, subtrian- 

 gular, bifid, the two points bearing rather long compressed subspat- 

 ulate styles. 



Length of body, 29 mm. ; of tegmina, 41 mm.; of hind tibiae, 27.5 

 mm. ; distance of tip of wings beyond the hind edge of prothorax,
