number of these species names were never published. Others were doubtfully 
attributed to Breddin (see Osborn, 1926b, pp. 209, 226, 227, 248). 
In a dorsal view of the crown, the dorsal portion of the face is readily visi- 
ble and this has been shown in the accompanying illustrations as an aid in 
showing the presence or absence and the extent of the carina which separates 
the crown from the face. 
Except for the structures illustrated here, the genitalia of the male lectotype 
of Tettigoniella apulia Distant are like the present illustrations of M. semicinctula 
(Osborn) (fig. 409). Species misdetermined as apulla in MMB have been 
correctly placed in the Neocoelidiinae by subsequent students of the collec- 
tion. 
The male lectotype of Tettigonia atramentatula Breddin has genitalia like the 
specimen from Pozuzo, Peru illustrated in figure 423. The male genitalia of 
the lectotype of Tettigoniella tractatula Jacobi, of the male lectotype of 
Tettigoniella cruentula Breddin, and of the male holotype of Tettigoniella thea 
Distant are also like the same illustrations. 
The genitalia of the male holotype of Graphocephala attenuata Osborn are like 
figure 404. 
The male lectotype of Tettigoniella azeka Distant is closely related to M. 
ferrugatula (Breddin). The genitalia of this specimen are like the present illus- 
trations of the specimens of ferrugatula from Itaituba, Brazil (fig. 397), except 
that the paraphyses are slightly longer, acute apically, and symmetrical. 
The genitalia of the male lectotype of Tettigoniella braccatula Jacobi are like 
the illustrations in figure 402. 
I have not seen either the type or the paratype of Mesogonia_ brevisula 
(Osborn), nor any determined specimens of this species. There is a possi- 
bility that it may preempt the new species, M. suspecta, described below. 
The genitalia of the male holotype of Graphocephala cardinula Osborn are like 
figure 425. 
Mesogonia ferrugatula (Breddin) is an extremely variable species both in color 
pattern and the degree to which the pygofer processes of the male are 
developed. The latter vary from fairly well developed as in the specimen from 
Archidona, Ecuador (fig. 3979-t) to completely absent in a specimen from 
Yungas de Palmar, Bolivia (not illustrated). The genitalia of the male lec- 
totype of this species are as in the present illustrations of the specimen from 
Coroico, Yungas, Bolivia (fig. 397c, h). The form of the aedeagus is the most 
important character for the identification of this species. The holotypes of 
both Graphocephala simillima Osborn and G. contractula Osborn have male 
genitalia falling within the range of variation of ferrugatula. 
The holotype of Graphocephala involuta Osborn has male genitalia which 
agree well with figure 416, as does the holotype of G. separata Osborn. The 
holotype of G. affinula Osborn is identical to the holotype of separata in exter- 
nal characters. 
The male lectotype of Kolla ithra Distant has genitalia like the present il- 
lustration of the specimen of M. ferrugatula (Breddin) from Itaituba, Brazil. 
The specimen was compared with the lectotype of M. azeka (Distant), with 
closely similar genitalia. The head of ithra is much more produced than azeka,
