This Mexican species, described from Yucatan, has been taken 

 at Miami, Fla., by both Davis and Hebard. The former (1914, 

 197) records the taking of a single male after night, Sept. 22, 

 while "shining the road" that leads through Brickell's Hammock 

 with a lantern. Hebard (1915b, 457) mentions the taking, on 

 March 5, of a nymph by beating heavy shrubbery in a dense jungle 

 at the same place; these two records being the only ones of both 

 genus and species from the United States. 



Like the small mantis, Muntoida may a S. & Z., also originally 

 described from Yucatan, P. may a is a tropical introduced form 

 which Avill probably be found only sparingly in the southern third 

 of Florida. 



Subfamily II. PSEUDOPHYLLIN^:. 



THE TRUE KATYDIDS. 



Our eastern species of this subfamily are insects of large size, 

 having the head very broad, fastigium of vertex short, triangular, 

 acute, grooved above, crowded by the prominent, widely margined 

 anteunal scrobes; eyes small, subglobose, very widely separated; 

 antennae reaching far beyond the closed tegmina; pronotum saddle- 

 shaped, its disk with faint lateral carinse, rounded into the perpen- 

 dicular lateral lobes, front margin truncate, hind one broadly 

 rounded ; prosternum armed with two slender tapering spines ; 

 tegmina very broad, ovate, leaf-like, usually strongly concave 

 within, wholly enclosing the abdomen, their anal field short, trian- 

 gular, overlapping, the sutural margin beyond straight or feebly 

 curved into the broadly rounded tips, the costal field crossed by 

 numerous straight parallel vein lets; wings shorter than tegmina; 

 membranous, very thin, rarely used in flight; meso- and inetas- 

 terna not lobed; all the femora sulcate and armed beneath; fore 

 tibia? without apical spines, hind ones 4-sided with all the margins 

 spined; first two joints of hind tarsi with sides sulcate. Males 

 with stridulatiug organ very highly developed, the transparent 

 speculum of each tegmen depressed or sunken and set in a strong 

 half-oval frame, the left or upper one with a strong stridulating 

 cross-vein near the base; cerci broad at base, widely forked, the
