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

 longifolia^ 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. oblongifolia, 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.
