490 FAMILY VII. TETTIGOXIIDJE. THE KATYDIDS. 



small, subglobose; antenna? very slender, reaching beyond middle 

 of tegmina ; disk of pronotum slightly concave, narrowed in front ; 

 lateral carinae distinct, obtuse in front, higher, sharper and cren- 

 ate on basal third; front margin feebly sinuate, hind one very 

 broadly rounded or subtruncate ; humeral sinus narrow, deep; 

 lateral lobes much deeper than long, their lower margin broadly 

 rounded into both the hind and front ones; tegmina subcorneous, 

 broadly lanceolate, their anal fields flat, forming a right angle 

 with the median one, dorsal margin behind the anal field slightly 

 sinuous and at apical fourth abruptly decurved to the narrowly 

 rounded apex ; lower margin broadly curved from base to middle, 

 thence nearly straight to apex (Fig. 163, a) ; wings with folded 

 tips acuminate, distinctly longer than tegmina; front and middle 

 femora terete, unarmed, hind ones armed beneath with a number 

 of small distant spines; lobes of knees bispinose; hind tibise four- 

 sided, the upper, inner and outer sides rather wide, flat, feebly con- 

 cave, the lower one narrow, the four margins raised and armed 

 with numerous teeth ; rneso- and metasterna with large triangular 

 lobes. Male with supra-anal plate triangular, sulcate; cerci ex- 

 cavated above, abruptly incurved ; subgenital plate as in Microcen- 

 tnim. Ovipositor very small, narrow, gradually curved upward, 

 its apex obtusely pointed. 



This American genus of giant katydids has been recently 

 (1917) reviewed by Rehn, who recognized eight species as belong- 

 ing to the faunas of South and central America and the West In- 

 dies, one of which is known to extend into Florida as far north as 

 Gainesville.

Eustis, Fla., April 6, one female; Cape Sable, Fla., Fob. 20, one 

 female (W. 8. B.}. The Eustis specimen was taken with the fin- 

 gers as it was resting on a leaf along the border of a cultivated 

 field, while the Cape Sable one was beaten from the foliage of a 

 saffron-plum, BiniicJia <ni</itKtifoli<i Nutt., growing along the edge 

 of a salt marsh hammock. The other Florida localities recorded
