492 FAMILY VII. TETTIGONIID.E. THE KATYDIDS. 



in their slightly larger size and more divergent lateral carina? of 

 pronotnm. These are probably what Rehn considers 8. quadrata 

 Scudder (ISGOc, 331), as that is the only species he mentions as 

 inhabiting Mexico. This species he also separates from inorgin- 

 ella and coulon'uuut only "by the greater breadth of the male teg- 

 minal field, with margin more obtuse-angled and the more elong- 

 ate stridnlating vein," and states that Florida females of coulon- 

 iana "are almost indistinguishable from Mexican individuals." 

 i. e., females of what he considers (/uadrata. 



An examination of a series of males of the three forms, mcir- 

 gincUfi, conloniana and quadrahi, in the Philadel])hia collections, 

 shows that the free margin of the left teginen I in. Fig. 163, b, c) is 

 slightly more obtusely rounded in qnadratti than in couloniana, 

 and slightly less so in niargincllii than in couloniaiui. A large 

 series would probably show that quad rat a is a synonym of cou- 

 IOH i(i)ui and that the latter is at the most only a race or form of 

 marginella. 



VII. TURPILIA Sti\I, 1874, 16. 



This genus is closely allied to Microcentrum, its species differ- 

 ing mainly by their smaller size and the characters given in the 

 generic key. They have the fastigium much narrower, but slight- 

 ly decurved; disk of pronotum proportionally longer and nar- 

 rower, much more strongly punctate; tegmina relatively more lan- 

 ceolate and more densely reticulate ; lobes of meso- and metasterna 

 longer, triangular, their tips acute. 



224. TURPILIA ROSTBATUM (Rehn & Hebard), 1905, 43. Narrow-beaked 

 Katydid. 



Size medium, the sexes subequal. Bright green, more or leso suffused 

 with yellow; in dried specimens the apical half or more of tegmina and 

 protruding tips of wings usually alone green, the remainder dull brown- 

 ish-yellow. Fastigium as described in key, distinctly sulcate, its apex 

 rounded. Disk of pronotum with lateral carinse evident but rounded, 

 more distinct on basal half, front margin broadly and shallowly concave, 

 hind one strongly rounded; humeral sinus rather broad and shallow. 

 Tegmina ovate-lanceolate, apex narrowly rounded, surpassing tips of hind 

 femora about one-third their length. Wings protruding 4 5 mm. beyond 

 the tegmina. All the femora feebly spinulose beneath. Male cerci very 

 long, tapering, nearly straight, surpassing the subgenital plate, their tips 

 armed with a pair of minute apical teeth, and a third ventral subapical 

 one; subgenital plate broad, tapering, its lateral carina? faint, apex sub- 

 truncate, with a minute median rounded notch; styles short, feebly taper- 

 ing. Ovipositor with both ventral and dorsal margins of apical half finely 

 crenulate, the apex broad, bluntly rounded. Length of body, $ , 20 21,
