obtusely and blniitly aiifnilate; lateral lobes vertical, their lower border 

 very obtusely aii;;ulati' in tiie middle. Prosternal spine i>r(>minent, 

 subeylindrical, bluntly pointed, laterally eonipressj'd al the base, at 

 least in the nuile: in«;sostermil lobes narrowly separatetl in both «exes; 

 nietasternal lobes subattinjj^ent (nnilei or as distant as tlie mesosternal 

 lobes (female). Te^niiiia jind win«;s variable, but at least as \o\\^ as 

 the pronotuni. Hind femora reaching or fjenerally surpassing; the tip of 

 the abdomen, UKMlerately stout but taperinj; very regularly, unarnuMl 

 above, the inferior genicular lobes pnxluced but apically rounded, 

 nnirked at base with a transverse dark bar; spined margins of hind 

 tibiae smooth, scarcely dilated toward the tip, juovided on outer margin 

 with nine to thirteen, generally eleven, spines, the larger nund)er being 

 more common in the female. Subgenital plate of male short, transverse, 

 of subequal width throughout, more or less tumid, the lateral margins 

 nmpliato at the base; aiml cerci of male long, lannnate, subclepsydral 

 in shape, incurved; edges of inferior valve of ovipositor smooth. 



This genus bears a <;lo8e general resemblance to the geront(»geic 

 genus Oxya, but difl'ers strikingly frcmi it in the separated metasternal 

 lobes of the female, the blunt tips of the inferior genicular lobes of the 

 hind femora, the smooth edges of the hin<l tibiae and the absence of 

 the terminal spine of the outer series of the same. It is very narrowly 

 separable from Melanoplus, and I do not see how it could be distin 

 guished from it if we include in it, as Still did, his Pvzotettir plebejus 

 ijud nisticus. The combination of such peculiarities as the long 

 antennae and strongly transverse subgenital plate of the male with 

 the long and parallel sided i)ronotum of both sexes serves to distin- 

 guish it from Melanoplus, as here limited; while the strongly banded 

 sides of the body and the long and clepsydral cerci of the male in all 

 the species mark it as a peculiar type even if the.^e markings and form 

 of genitalia do occur in certain species of the diversified genus 

 Melanoplus. 



Three species are known and appear to be confined almost entirely to 

 our Atlantic and Gulf borders, though some of the species occur as far 

 inland as Indiana, Ohio, and Michigan. It is unknown west of the 

 ^Mississippi, except in Louisiana and Texas (though Professor Bruner 

 suspects its presence in Nebraska). They inhabit moist places. 



The type is P. /or*(?a»«. 



ANALYTICAL KEY TO THE SPECIES OF I'ARO.VYA. 



A'. Antennae and cerci of male relatively short; fnrcnla of male consisting of a 



pair of triangular plates; tegmina at least as long as body 1. aUauiha (p. 3S2). 



A-. Antennae and cerci of male relatively long; furcula of male consisting of a pair 



of subequal tingers; tegmiua variable. 

 6'. Furcula coarse, heavy, and depressed, generally straight; supraanal plate 



short triangular; tegmina much shorter than body 2. hoonvri (p. 382). 



ft-. Furcula relatively slender, cylindrical, often divergent; supraanal plate long 

 triangular ; tegmina normally as long as body but very variable. 3. Jtori(lana{\}. 3k3).
