Graphocephala. The group is chiefly Central American, although there are a 
number of North American species, and Graphocephala has representatives in 
Colombia and French Guiana. There are also records of Jsogonalia from Peru 
and Santarem, Brazil, as noted above. All have abdominal sternum VII of the 
female produced, and a similar chaetotaxy of the female pygofer. There is 
much similarity, also, in the second valvulae of the ovipositor, except in some 
species of Graphocephala and in Manzutus and Plummerella of which both of the 
last appear to have diverged in restricted habitats. 
In some species in this complex, the hind knees do not reach the posterior 
proepimeral margins in repose, as discussed in part 1 of the present reclassifi- 
cation (Young, 1968a:16), a condition probably derived within the 
Graphocephala generic group. 
The complex may be related to Trichogonia Breddin (cf. discussion above) as 
indicated by similarities in the females of Graphocephala nigrifascia (Walker) and 
G. appropinquans (Fowler) with species in the Trichogonia complex. 
I. sexlineata (Signoret) was collected at the mouth of the river in the city of 
Vera Cruz, on Pluchea odorata Cassini, by N. L. H. Krauss, and in Fortin, Vera 
Cruz on Eupatorium adenophorum Sprengel by the same collector. A series of 
specimens was collected in Guatemala on Cinchona by N. L. H. Krauss. A 
series of specimens was also collected on Geranium in San Pedro de Montes de 
Oca, Costa Rica, by C. H. Ballou. 
There is a great deal of variation in the markings of the anterior dorsum in 
sexlineata. In some specimens the black markings are narrower, or narrower 
and less complete than in fig. 661a. There is also variation in the degree to 
which the aedeagal processes are separate at their bases (figs. 661r-t).
