Chromogonia Melichar (1926a:342) is represented by two females in MMB. 
These were not at hand as this was written. The type-species listed by Evans 
(1947a:160) is a nomen nudum. 
Derogonia Melichar (1926a:353), type-species: Tettigonia pilipennis Signoret 
(1854b:342), by subsequent designation of Evans (1947a:161), is unknown to 
me except from a single female specimen in the NMV. It is from Colombia 
and therefore not eligible to be lectotype (the type-locality is Bolivia). It is 
probably correctly identified, for it has the peculiar lobes of abdominal ster- 
num VII that Signoret mentioned in the original description. It was not at 
hand as this was written. 
The genus Ectypus Signoret (1853e:263) is known to me only from the 
original description, based on a single female of the type-species, E. cortaceus 
Signoret (1853e:265), a brachypterous specimen without ocelli, and from the 
colored illustration which accompanied the description. Signoret thought it 
might be related to Aulacizes, and the illustration had the appearance of a 
proconiine leafhopper. 
The monobasic genus Homalogoniella Melichar (1925a:341), type-species: 
Tettigonia pubescens Signoret (1854d:721), has been placed in the group now 
known as Cicadellinae by Signoret, Melichar, and Evans. I have seen one 
specimen without abdomen and with no locality label (fig. 887) and one 
female from Rio de Janeiro, both in the MMB. The lateral clypeal sutures ex- 
tend onto the crown and attain the ocelli, but otherwise the specimens are 
more like ledrine leafhoppers than like Cicadellinae in appearance. The body 
is dorsoventrally flattened, the disk of the crown concave, the femoral setal 
formula of the hindleg is 2:0:0, there is a keel separating the crown from the 
face, the forewings are reticulate, and the entire dorsum is beset with black 
pubescence. 
Metascarta Melichar (1926a:341), type-species: Tettigonia flavipes Signoret 
(1854a:22), by subsequent designation of China (1938d:183), is unknown to 
me. I found no specimens of flavipes in Signoret’s collection in Vienna. There 
were two specimens under this name in the MMB, but they were without 
locality labels, and possibly Cicadella viridis (L.). Signoret gave Bolivia as the 
type-locality. 
Paragonalia Evans (1947a:163) was proposed as a new name for Paragonia 
Melichar (1926a:342), preoccupied, type-species: Tettigonia sanguinicollis 
Latreille (1811a:191), by subsequent designation of China (1938d:183). Only 
the type-species and its synonym (fidé Signoret) Tettigonia farinana Amyot and 
Serville (1843a:570) have been included in Paragonalia. | have not seen a deter- 
mined specimen of either of these nominal species, nor a specimen conforming 
to Signoret’s (1853b, pl. 12, fig. 12) illustration. 
Species of Uncertain Position 
Tettigella alba Metcalf (1955a:264, new name for Tettigonia concinna Walker, 
1851b:755, preoccupied) is known to me only from the holotype in the BM 
with missing forewings and from an unknown locality.
