CICADELLINAE: PART 2. NEW WORLD CICADELLINI 247 
Species of Caragonalia occur only in southeastern Brazil. Caragonalia is 
similar to Chichahua, new genus, in the description of which distinguishing 
characters are treated. In color, C. carminata is similar to Pawiloma ancora, n. 
sp. 
My interpretation of C. carminata (Signoret) is based on an examination of a 
female in NMV determined by Signoret. There were no additional specimens 
from the type-series. A male in a series of specimens in MHNP agreed with 
the illustrations here. Specimens in the BM determined as rutilans Walker 
were conspecific. 
I have examined the female lectotype of Tettigonia monstruosa Signoret (fig. 
200) and the male lectotype (fig. 199) of 7. tarsalis Signoret, both in NMV. I 
have not seen a male of monstruosa, but females of tarsalis (fig. 1997) differ from 
the lectotype of monstruosa. Signoret, in the original description of tarsalis, dis- 
cussed the similarity to monstruosa, and I cannot separate the species other 
than by the female structures illustrated here.

Type-species: Chichahua stygiana, new species. 
Length of male 8.9-10.4 mm, of female 9.2-9.5 mm. 
Head not or only moderately produced, anterior margin broadly rounded, 
median length of crown from slightly more than one-half to almost three- 
fourths interocular width in male and from four-tenths to approximately one- 
half interocular width in female; median length from four-tenths to one-half 
transocular width in male and approximately one-third transocular width in 
female; with or without a carina at transition from crown to face (variable 
interspecifically), ocelli located on or before a line between anterior eye 
angles, closer to median line than to adjacent anterior eye angle in male, each 
equidistant from adjacent anterior eye angle and median line of crown in 
female; crown with a shallow median broad concavity and one on each side, 
the median one extending farther forward in the male, surface without 
pubescence; clypeus strongly concave medially and with muscle impressions
