but is most often short and without processes, and without the basal portion 
found in Campecha Melichar. The occurrence of rugae on the antennal ledges 
and of macrosetae on the female pygofer in Graphocephala will separate it from 
Decua Oman. The genitalia of the females of nigrifascia and appropinquans (fig. 
712) are similar to those of Stehlikiana, new genus (see discussion of Trichogonia 
Breddin). 
I have been unable to find a sufficient gap between Proconia confluens Uhler 
and other species treated below to justify retaining Neokolla Melichar as a dis- 
tinct genus. Hordnia Oman and Marathonia Oman have been reduced for 
similar reasons. Neokolla Melichar, which Oman (1949a:73) used to include 
species with symmetrical male genitalia, has for its type-species Tettigonia 
hieroglyphica Say, of which the type-specimen no longer exists. I have examined 
a specimen determined as hueroglyphica by Ball, and agreeing with Ball’s 
(1901e: pl. III, fig. 1) illustration, which has asymmetrical genitalia identical 
with those of Oman’s lectotype of Tett:gonia dolobrata (Ball). The resulting 
specific synonymy (see list of species) resulted in the reduction of Neokolla 
Melichar to synonymy under Graphocephala. 
A series of Graphocephala apicata, n. sp., was collected by N. L. H. Krauss on 
Lantana camara L. in San Blas, Nayarit, Mexico, July 29, 1953 (USNM). 
G. atropunctata (Signoret) was taken from leaves of Lantana in Casa Colorado, 
Nicaragua, November, 1959, by N. L. H. Krauss. This species (as circellata 
Baker) has been collected on a number of plants (see summary by Nielson, 
1968c:117) and is an important vector of Pierce’s disease of grapes and alfalfa. 
Additional biological studies are also cited by Nielson (loc. cit.). 
Specimens of G. aurora (Baker) in the USNM were collected on Eupatorium 
adenophorum Sprengel. 
G. coccinea (Forster) has been shown to feed on a number of plants in the 
U.S.A., including milkweed, and on several ornamental plants. DeLong 
(1948a:145) gave Rubus and Forsythia as examples of such plants on which eco- 
nomic damage may be inflicted. The species occurs in numbers on ornamen- 
tal plantings of Pittosporum on the campus of North Carolina State University. 
Ballou (1935a:193) reported having collected coccinea on 23 species of plants in 
Costa Rica, and on 36 species in 1936 (1936b:463), the total list including a 
number of economic species. In Missouri, Mason and Yonke (1971b:115) 
reported adult coccinea feeding on Silphium perfoliatum L., S. integrifolium Michx., 
Rosa multiflora Thunb., Cirstum sp., Asclepias sp.; and last instar nymphs were 
collected on Rhus aromatica Ait., Rosa multiflora, and Solidago sp. 
A series of G. clepsydra (Fowler) in the USNM was collected on Pelargonium 
<onale Aiton, February 10, 1935 in San Rafael de Coronado, Costa Rica, by 
C. H. Ballou. 
G. cythura (Baker) has been reported as a vector of Pierce’s disease of grapes 
(Nielson, op cit., p. 120) but not an effective one. 
Sefiora Graciela Serrano Limon, in an unpublished thesis, reported G. 
nigrifascia (Walker) to have Buddleia humboldtiana Roem and Schultz as a host 
plant. 
Three specimens of G. pectoralis (Fowler) in USNM were intercepted on 
Tillandsia sp.
