with a median dorsal flattened apical process which is slightly variable intra- 
specifically, with a broad flattened broadly truncate aedeagal process arising 
from ventral portion of atrium, extending parallel to and behind shaft to its 
apex. Paraphyses absent. 
Female abdominal sternum VII strongly produced posteriorly with apex 
broadly and regularly convex except medially (fig. 6787). Genital chamber 
without a median or lateral sclerites. Ovipositor with second valvulae each 
broadened beyond basal curvature, with broad quadrate sloping teeth occur- 
ring throughout broader portion almost to apex, with minute secondaries on 
the quadrate teeth and minute denticles on posterodorsal and posteroventral 
anteapical margins; apex subacute. 
Species of Manzutus occur in southern Arizona and as far southward in 
Mexico as Hidalgo and Michoacan. Oman (1949a:73) reported that M. 
huachucanus (Ball) lives on Arctostaphylos and (M. multilineata (Fowler)) = M. 
mexicanus (Signoret) on the Arbutus tree. 
Manzutus Oman belongs to the Jsogonalia complex of genera, discussed un- 
der the latter generic heading. Manzutus males are distinctive in the unpaired 
median symmetrical process of the aedeagus, and the females differ slightly 
from those of Jsogonalia, new genus, and Amphigonalia, new genus, in the form 
of the apex of the second valvulae which are less acute apically (fig. 678m) 
than in /sogonalia and Amphigonalia. The divergence of these characters may be 
related to the restricted food plants of the species of Manzutus. 
My interpretation of Tettigonia multilineata Fowler is based on a dissection of 
a male specimen compared with the Fowler type in the British Museum. The 
present interpretation of 7. mexicana Signoret is based on a dissection of the 
lectotype of that species. I have based my interpretation of Cicadella huachucana 
Ball on specimens determined by Oman, from the USNM. The male genital 
structures of Auachucana not illustrated are like those illustrated for mexicana.
