tending slightly anteroventrally near pygofer margin. 
Most species of Caldwelliola are dull green except for the tan to yellow head, 
anterior portion of the pronotum, and the scutellum (exception: C. /utea 
(Signoret) which is entirely pale yellow). The crown usually bears some 
brown or black markings. 
Caldwelliola, new genus, occurs from Central America, Trinidad and Tobago 
Islands in the West Indies, and from Venezuela and Colombia to Bolivia. 
Most species of Caldwelliola are similar in appearance to Chlorogonalia ultima, n.- 
sp., and superficially to Crossogonalia hectica (Signoret). Males of Chlorogonalia, 
new genus, have greatly reduced sternal abdominal apodemes in contrast to 
Caldwelliola; and males of Crossogonalia species have long, fine setae on the 
male plates, in addition to symmetrical paraphyses, in contrast to Caldwelliola. 
The true relationship of Caldwelliola to other genera is problematical. I have 
placed it near Borogonalia, new genus, because of the similarity of the male 
genitalia in the two genera. The lobate aedeagal apex of Borogonalia and the 
uniseriate macrosetae of the plates of Caldwelliola serve to separate them. 
Caldwelliola andamira, n. sp., has been collected on Vernonia sp. in Venezuela; 
C. caucana, n. sp., on Soya in Colombia. 
I have not seen typical specimens of Tettigonia lutea Signoret. My identifica- 
tion of this species is based on the original description and Fowler’s illustra- 
tion. 
My interpretation of Tettzgonia reservata Fowler is based on specimens com- 
pared with the original illustration of that species. The anterior dorsum of 
reservata is like that described for C. caucana, n. sp., but there are no black 
spots on the scutellum. 
Caldwelliola, new genus, is named in recognition of the progress achieved by 
Dr. John S. Caldwell in the development of our knowledge of the 
auchenorrhynchous fauna of the tropics of the New World.
