CICADELLINAE: PART 2. NEW WORLD CICADELLINI 107 
The anterior dorsum of the lectotype of Cicada fastuosa Fabricius is like the 
accompanying illustration. 
One of two female specimens from the Taschenberg collection from Martin 
Luther University, Halle an der Salle, East Germany, is presently designated 
lectotype of Tettigonia frenata Taschenberg and has been so labeled. There are 
no labels on the pin bearing the specimens, but pinned separately was the 
label: “‘frenata m/Venezuel.”. The specimen agrees with the illustration pub- 
lished here. 
The genitalia of a male specimen, compared with the female holotype of 
Tettigonia gaudens Walker, agrees with fig. 94. 
The identity of Tettigonia hexaptera Burmeister is unknown to me, as it was 
to Signoret (1850b: 288). 
A male, from Panama, compared with the female type of Cicadella hyalinatula 
Osborn, from Colombia, is the basis for my interpretation of that species. 
The lectotype of Tettigoniella jemima Distant agrees with the illustrations 
published here. 
Signoret (1850b: 287) described Dilobopterus klugi from a male. In the 
museum in Vienna, there are three specimens on a single pin, two of them fe- 
males, the third without abdomen, bearing a ‘‘Cayenne”’ label and Signoret’s 
determination label. These specimens belong to D. dispar (Germar) as inter- 
preted here, and the determination label may be an error. The original des- 
cription of klugi fits dispar well enough, but in the absence of a type specimen 
it seems advisable to retain it as an unknown species until it becomes clear 
that no other museum has the type. 
The present interpretation of Tettigonia laeta Walker rests on the female 
holotype and a male compared with that specimen. The interpretation of 7. 
fervens Walker is based on an examination of the female holotype and a com- 
parison of this specimen with the holotype of daeta. 
A male compared with the female lectotype of Tettzgonia lineosus Fowler has 
genitalia much similar to the illustrations of D. pardalinus (Fowler) but with 
slight differences in paraphyses and with styles slightly longer. A male com- 
pared with the female lectotype of 7. pardalina has genitalia like the illus- 
trations published here except that the aedeagus is like the present il- 
lustration of the lectotype of Tettigonia instrata Fowler and like a male of a 
specimen compared with the lectotype (which is without an abdomen) of Tet- 
tigonia quinquestgnata Walker. Dilobopterus instratus, D. quinquesignatus and D. 
pardalinus appear to be distinct externally. Tettigonia multivirgata Stal is placed 
in synonymy under D. quinquesignata (Walker) on the basis of the close simi- 
larity of drawings of the anterior dorsum and forewing of the lectotype of the 
Stal species (abdomen and legs missing; hindwings damaged) to the lecto- 
type of the Walker species. This Central American complex of species is a dif- 
ficult one, and long series of specimens are needed for study, but only short 
series are available. 
Dilobopterus mosaicus (Fowler) is unknown, except from the illustration ac- 
companying the original description. The writer found no specimens in the 
Naturhistorisches Museum in Vienna, and no specimens from Mexico have
