Female abdominal sternum VII with a median posterior projection that is 
narrowly rounded apically. Ovipositor with second valvulae each broadened 
beyond basal curvature, with quadrate teeth extending from base of broad- 
ened portion almost to apex, the anteapical teeth progressively smaller, apex 
narrowly rounded, without anteapical denticles on dorsoapical or ventro- 
apical margins. Pygofer with a group of macrosetae on apical third and ex- 
tending anteroventrally near margin. 
The female second valvulae and pygofer are not illustrated. The shape of 
the second valvula is near the illustration of Acrulogonia sparsa, n. sp. (fig. 
535m) but the apex is more acute in Ambigonalia varicolor (Signoret). 
Signoret described Tettigonia varicolor from specimens from Honolulu. I dis- 
sected the male lectotype and illustrated the genitalia, but noted that the 
genitalia might be abnormal because of the membranous apex of the 
aedeagus. Dr. Kramer identified specimens, using Signoret’s figure, from 
Olmos, Lambayeque, Peru as varicolor and sent them to me, recently. The 
male genitalia were nearly identical with my illustrations of the lectotype. I 
have seen no other specimens from Hawaii. If the two specimens in NMV are 
not mislabeled, the distribution of the genus is very puzzling. 
Ambigonalia is close to Macugonalia, new genus, but is not closely mottled as 
are species of the latter. The head is more produced in Ambigonalia than in 
Macugonalia and the males lack macrosetae on the plates, but have para- 
physes, differing in these characters from Macugonalia.
