Female (unknown in concinnula) abdominal sternum VII elongate, with 
posterior margin convex. Ovipositor with second valvulae each expanded in 
portion beyond basal curvature, with widely spaced triangular teeth in basal 
portion of expanded portion, teeth slanting and quadrate more distally, apex 
acutangular. Pygofer narrowed and acute or narrowly rounded postero- 
dorsally, macrosetae occurring dorsally and anteapically. 
Specimens of Allogonia, new genus, have been studied from southern 
Arizona, central and southern Mexico, Honduras, El Salvador, Costa Rica, 
and Panama. Allogonia belongs to the Jsogonalia (q. v.) complex of genera. 
Females differ from others in the complex in the more elongate abdominal 
sternum VII which is also. more slender than in other genera. In the males the 
paraphyses consist of a short, usually symmetrical sclerite near the base of the 
aedeagus which may or may not have processes like those of Amphigonalia, new 
genus, and Manzutus Oman. There are no pygofer processes in males of 
Allogonia, and the male plates are shorter in relation to the pygofer, both 
features differing from Amphigonalta. 
Tettigonia completa Fowler is identified here on the basis of a female specimen 
I compared with the lectotype in the British Museum. 
My interpretation of Tettigonia concinnula Fowler is based on an examination 
of the male lectotype and a dissection of a male (fig. 674a, c-e, p) compared 
with this specimen in the British Museum. 
Tettigonia flavivitta Fowler has been identified in the sense of a male com- 
pared with the male lectotype (fig. 671). The male lectotype of 7. induta 
Fowler has genitalia much like the present illustration (fig. 675). 
I studied the female lectotype of 7. luculenta Fowler in BM, and made draw- 
ings of the anterior dorsum and of abdominal sternum VII. The only 
specimens I have seen that appear to be conspecific are a pair from the Santa 
Catalina Mountains, Arizona, from the Ball collection (USNM). Other 
specimens similar in éxternal appearance and from Mexican localities belong 
in Graphocephala. 
My identification of Tettigonia superflua Fowler is based on a dissection of the 
male lectotype (fig. 673) of that species. Although I have seen the lectotype of 
T. robustula Fowler, my interpretation of this species is based largely on 
specimens examined later and compared with Fowler’s original illustration.
