24. PLEBFJUS SFKIES. 



In this somewhat homogeneous group, the prozona is distinctly 

 longitudinal in both sexes (the female of one species is not known) and 

 nearly or quite half as long again as the raetazona, the posterior margin 

 of which is subtruncate or truncate or sometimes very obtusangulate. 

 The interspace between the mesosternal lobes in the male is more than 

 twice, sometimes thrice, as long as broad. The tegmina are very vari- 

 able; one species is <limorphic, having either fully developed tegmina 

 and wings considerably surpassing the tips of the hind femora, or 

 ovate lanceolate overlapping tegmina, acuminate at tip and a little 

 longer than the pronotum; another is macropterous with subequal 

 tegmina, reaching the tii)S of the hind femora; the other species are 

 l)rachypterous, but the tegmina are variably shaped, — sometimes as 

 in the brachypterous form of the dimorphic species, at others either 

 rounded ovate and attingent, or widely sei)arated and lateral. 



The supraanal plate is triangular, with generally a tolerably jdane 

 surface; the furcula is obsolete, subobsolete, or reduced to mere brief 

 (lenticulatious; the cerci are long, constricted in the middle, but 

 expanding only a little apically, incurved, and bluntly rounded or 

 inleriorly subacuminate at tip; the subgenital plate is always small, 

 distinctly narrower than long, often narrowing apically, and sometimes 

 ends in a tubercle. 



There are five species, most of them widely separated from one 

 another: one occurs in the upper Mississippi valley from the Dakotas 

 to Kentncky, while the others are found respectively in Florida (two 

 si)ecies), Texas, and California.
