to Miami and Punta Gorda, and probably occurs everywhere 

 throughout peninsular Florida. North of that State it is definite- 

 ly known only from Tybee and St. Simon's Islands, <ia., though 

 Brunei 1 has recorded it from Nebraska and Bolivar from Mexico. 

 No examples of a short-winged form have as yet been noted. 



Subfamily II. BATRACHIDIN^E. 



The members of this subfamily are distinguished mainly by the 

 characters given in the key, p. 153. In addition lliey have the 

 size large and form robust for the family; frontal costa narrow, 

 its ridges obtuse, subcontiguous, subparallel and continuous with 

 the median carina of vertex; eyes large, oval or subtriangular, not 

 strongly convex, their upper inner border encroached upon by a 

 small crescentic lobe of the vertex; antenna? inserted between the 

 lower halves of eyes; pronotum strongly tectiform, usually with 

 more or less obvious lengthwise ruga?, its median ridge never 

 strongly carinate or cristate; first joint of hind tarsi not longer 

 than third. Two genera are represented in the Eastern States. 



KEY TO EASTERN GENERA OF BATRACHIDIN.E. 



a. Body robust, subglobose (Fig. 64.) ; lateral carinse in front of should- 

 ers wanting; pronotum convex above, feeble punctate. I. PAXILLA. 

 aa. Body narrower, more slender (Fig. 66); lateral carinse present; pro- 

 notum between the carinse more or less concave and rugose, granu- 

 lose or wrinkled. II. TETTIGIDEA. 



I. PAXILLA Bolivar, 1887, 294. (Lat., "A small peg.' 1 ) 

 Form robust, compressed. Head broad ; vertex short, curved 

 in front, transversely carinate each side, disc with a prominent 

 lengthwise median carina projecting in front of eyes and rounded 

 into the frontal costa, the latter narrowly sulcate above the me- 

 dian ocellus; antenna? 22-jointed; eyes rather small, subtriangu- 

 lar, the apex above ; pronotum compressed, its front margin acute- 

 angulate, extending over head to median carina of vertex; pos- 

 teriorly subacute, its apex reaching end of abdomen, male, base 

 of ovipositor, female, falling short of tips of hind femora in both 

 sexes; tegmina narrow; wings abbreviated; hind femora rather 

 stout, broad; hind tibia? with numerous spines; first joint of hind 

 tarsi sulcate above, as long as the next two united. One species 

 only is known. 



76. PAXILLA OBESA (Scudder), 1877b, 34. Obese Grouse Locust. 



Chocolate-brown, shining; the dorsal surface and lower third of lat- 

 eral lobes of pronotum and lower part of face often pale brown. Prono-
