been found corresponding with the illustration which is closer to the species 
described below as D. fenestratus than to any of the other species in the genus. 
Tettigonia multicolor Walker is known only from the female lectotype. It may 
be synonymous with D. demissus (Fabricius), but the scope of the variations of 
the latter were not realized at the time the Walker type was studied, and re- 
study is needed. 
I have studied the lectotype (NMV) and one additional female (OSU) of 
Tettigonia segmentalis Signoret. The female lectotype of Tettigonia approximata 
Stal agrees with figure 68. 
The present interpretation of Tettigoniella oliquatula Jacobi is based on a 
comparison of the female lectotype with a number of females from Peru and 
Bolivia. 
Dilobopterus stolli Signoret, as here interpreted, is based on the female lecto- 
type and Signoret’s (1853a, pl. 2, fig. 7) illustration of this distinctive species. 
Dilobopterus syrphoidulus (Jacobi) is a species with a great deal of variability 
in color pattern. The accompanying illustrations of the male genitalia agree 
with the genitalia of the male lectotypes both of this nominal species and of 
Tettigoniella lenea Distant. 
The present interpretation of Dilobopterus trinotatus (Signoret) rests on a com- 
parison of the female lectotype with the male of which the genitalia are il- 
lustrated here. Two specimens from Martin Luther University belonging in dif- 
ferent genera, were examined. Each was accompanied by a label: *‘Tettigonia 
flavofasciata Taschenberg’”’. Only one of the specimens agreed with the original 
description. I placed a “holotype” label with that specimen. It is conspecific with 
D. trinotatus (Signoret). 
The identity of Dilobopterus vicinus (Signoret) rests on a comparison of the fe- 
male lectotype with the illustration of the anterior dorsum published here, 
and similarity between the illustrated male and Signoret’s (1853, pl. 2, fig. 9) 
illustration.
