500 FAMILY VII. TETTIGOXIIDJE. THE KATYDIDS. 



dark slate color, about 6.5x2 mm. in size, very flat, pointed at 

 each end, and with the edges beveled off or emarginate. Caudell 

 (1906, 33) mentions a female that was found on Plumnier's Island, 

 Md., with the ovipositor inserted into the bark of a small elm tree 

 a few feet above the ground. Later (1918, 112) he records one 

 as ovipositing in the bark of the black walnut. 



226a. PTEROPHYLLA CAMELLIFOLIA INTERMEDIA (Caudell), 1906, 41. South- 

 ern True Katydid. 



Smaller than the average camellifolia. Color the same. Pronotum 

 with anterior transverse sulcus less deeply impressed. Tegmina of female 

 narrower, the hind margin, when spread, nearly straight, the tip narrowly 

 rounded. Cerci of male as described in key. Length of pronotum, $ , 5, 

 9, 5.5; of tegmina, .34, 9, 35.5; of hind femora, $ , 21. 9, 2021.5; of 

 subgenital plate $, 13; of ovipositor, 18 mm. Width of tegmina, $ , 18, 

 9 , 14 mm. 



Hollister, Mo., July 22 (Davis). Caudell's types were from 

 Biloxi, Miss., and Wellsboro, Texas. R. & H. (1916, 257) have 

 recorded a male from North Carolina and placed Intermedia as 

 the southern race of camellifolia, stating that their male is inter- 

 mediate between CaudelFs types and typical canicUifoUfi. The 

 Missouri specimen at hand is a female having the tegmina as de- 

 scribed by Caudell. A large series from the territory south of the 

 known range of camellifolia will be necessary to fix the true status 

 of intermedia. 



II. LEA Caudell, 1906, 42. I Without meaning. ) 



Larger, more elongate species than those of Ptcrofrtiyllci, hav- 

 ing the head narrower, vertex much the same; disk of pronotum 

 about one-half longer than the middle width, rugose, the prozona 

 one-fourth longer than metazona ; lateral lobes perpendicular, one- 

 third longer than high, hind margin straight, oblique, rounded 

 into the straight lower one; tegmina elongate-elliptical, two and 

 a half times as long as the middle breadth, both margins feebly 

 curved into the broadly rounded tips, the venation of the costal 

 field as in PteropJii/lla. All the femora armed below and the mid- 

 dle and hind tibiae above. Male with shrilling organ as in Pter- 

 opJii/Jhi ; supra-anal plate triangular, nearly twice as long as wide; 

 cerci widely forked, the base between the forks concave, branches 

 slender, tapering, the upper ones incurved and crossed, the lower 

 ones upcurved and subparallel ; subgenital plate long, slender, up- 

 curved, grooved above and beneath, deeply and narrowly forked at 

 apex, the tips acute. Female with ovipositor much as in Pter- 



i i/ll<i, slightly narrower and more upcurved; supra-anal plate
