* 2. P. ROTUNDiFOLiA, nov. sp. (Fig. 4), figured as P. ob- 

 long-ifoHa, Harris' Report, 3d ed., fig. 75. 



This species agrees with the preceding in coloration in 

 every respect, unless the color of the ovipositor of the fe- 

 male be different in fresh specimens. The wings and 

 wing-covers are much shorter than in P. oblong- if alia, the 

 wing-covers, in consequence, being more ovoid. It differs 

 from that species, also, in the shape of the prothorax, which, 

 in P. oblongifolia, is much narrower at the anterior than at 

 the posterior border, and has the angle formed by the de- 

 flexion of the sides quite sharp, while in P. rotundifolia 

 the posterior border is scarcely wider than the anterior, and 

 the angle of the sides is rounded. It is a smaller species 

 than P. oblongifolia. 



Length of body, .8 in. ; of wing covers, 1 in. ; of wings, 

 (when closed,) 1.17 in. ; of hind femora, .87 in. ; of ovipos- 

 itor, .37 in.

3. P. CAUDATA, nov. Sp. 



Similar in general appearance to P. oblongifolia, but 

 having a larger body, with slightly longer wings, much 

 longer legs, and a very long ovipositor. The prothorax is 

 narrowed anteriorly, as in P. oblongifolia, while the lat- 

 eral angles are rounded as in P. rotundifolia. The spec- 

 imen I have examined is old and discolored, but faint 

 tinges of green are left upon some parts, indicating that 

 the general color was as in the preceding species.
