CICADELLINAE: PART 2, NEW WORLD CICADELLINI 1051 
I am indebted to Dr. James P. Kramer for suggesting changes leading to 
the present form of the key to species. 
Judging from the host plant labels attached to a number of specimens 
collected by entomologists of the Agricultural Program of the Rockefeller 
Foundation, in Colombia, and loaned to me through Dr. R. F. Ruppel, 
Borogonalia is an important economic genus. They collected B. impressifrons 
(Signoret) from alfalfa, beans, beets, carrots, corn, Dolichos sp., grass, 
potatoes, and strawberries. I have also seen specimens from El Junquito, 
Venezuela which were collected on Buddleja americana L. As noted below, some 
specimens of B. crinata, n. sp., were collected on an unknown species of 
Asclepiadaceae in Abancay, Peru. 
My interpretation of Tettigonia impressifrons Signoret is based on a compari- 
son of the genitalia of the male lectotype with illustrations made earlier from 
-a specimen from Colombia. I have reduced Tettigoniella perspicillatula Jacobi to 

FIGURES 852, 853.—852, Borogonalia impressifrons (Signoret) (see also fig. 851) 
(c, e, from specimen from Zipaquira, Colombia, 7: from lectotype of 
Tettigoniella perspicillatula Jacobi). 853, B. cruciatula (Breddin) (2 from lec- 
totype; remainder from specimen from Bafios, Ecuador).
