Tettigoniella inca Distant of which the male lectotype has genitalia like the 
present illustration, has been compared with the female lectotype of T. 
rosenbergi Distant. 
A female specimen from DEI is here designated lectotype of Tettigonia incula 
Breddin. It bears labels: ‘‘Napo/(Ecuad.)/ R. Haensch S.” and ““Type” and 
“Tettigonia/incula/n. spec.” and ‘‘Coll. Breddin” and ‘‘Tettigoniella/incula/ 
Bredd./Q Edm. Schmidt/determ. 1910” and the lectotype label. A. incula 
(Breddin) is the commonest color of the female of A. opulenta (Walker). Most 
males are colored as in typical opulenta, but a male in USNM, colored like 
most of the females, has genitalia identical to typically colored males of 
opulenta. A male, compared with the female holotype of Tettigonia opulenta 
Walker has genitalia like the present illustration. Tettigonia resecta Signoret, a 
nominal species of which the type is unknown to the writer, is placed in syn- 
onymy on the basis of Signoret’s (1853b: pl. 8, fig. 5) original illustration. 
No specimens of Amblyscarta lignea (Fowler) have been seen. The species is 
placed in the genus on the basis of the original illustration. 
The teneral female lectotype of the type-species, Cicada modesta Fabricius, 
the only specimen seen by the writer, is undoubtedly congeneric with the 
other species here included in the genus. 
The present interpretation of Cicada pulchra Fabricius is based on similarity 
of the anterior dorsum of the female lectotype with the specimen illustrated 
here. 
Amblyscarta ruftceps (Walker) and A. resolubtlis (Fowler) are very closely 
related, differing chiefly in markings of face and form of the female ab- 
dominal sternum VII (only one female of resolubtls was at hand). 
Tettigonia schaumi Signoret is known only from the female lectotype. 
T. stillifera Stal is known only from the female lectotype. It is close to A. 
invenusta, n. sp. in size and facies, but differs in the shape of the posterior 
margin of the abdominal VII, in that it lacks an apical black spot on the 
crown (present in all specimens of invenusta at hand), and in lacking the sub- 
hyaline anteapical area of the forewings. 
The female lectotype of Tettigonia melancholica Fowler has the abdominal 
sternum VII like the present illustration of A. cervicula (Jacobi). The color of 
the wings is similar to that of A. invenusta, n. sp. I have seen an additional 
male, too late to include an illustration here, but the characters in the follow- 
ing key should suffice for identification purposes. 
The present interpretation of A. venosa (Signoret) rests on a pair of 
specimens in the Signoret collection in Vienna, both of which are from 
Colombia. The type locality is Bolivia. No additional specimens have been 
seen, and the species is without a type-specimen.
