CICADELLINAE: PART 2. NEW WORLD CICADELLINI 891 
Head with crown dull ivory, with a complex median dark brown to black 
design (fig. 705a), three black spots at apex and with faint brown marking 
along suture and giving off a branch towards apex of head and another 
toward inner eye margin; pronotum with a pair of broad longitudinal ivory 
bands that diverge posteriorly to humeral margins and a pair of narrower un- 
dulate ivory bands extending from anterior one-third to posterior margin near 
median line of scutellum, remainder brown, shading to black; scutellum ivory 
with basal angles black and a pair of narrow longitudinal brown stripes near 
median line; forewing pale brown with veins darker, a conspicuous 
longitudinal ivory band forming a continuation of each of the more lateral 
ivory bands of the pronotum, extending posteriorly diagonally across claval 
suture near its midlength, narrowing opposite claval apex and extending along 
margin of inner apical cell to wing apex, the band bordered with dark brown 
through most of its length, with a less conspicuous pale band along com- 
missural margin; face brown with yellow markings, apex of clypellus black; 
proepimeron brown with yellow markings; thoracic sterna black. 
Holotype male, Buena Vista, Guerrero, Mexico, K.340, October 23, 1941 
(DeLong, Good, Caldwell and Plummer) (DeLong collection, OSU). 
G. delongi, n. sp., is similar in form and male genital structures to G. teres 
(Fowler) from which it differs markedly in color pattern. G. delongi is also 
slightly more robust than teres. 
G. delongi, n. sp., is named in honor of Dr. D. M. DeLong whose collection 
of Mexican Cicadellinae has contributed very greatly to the present study.

FIGURE 709, PAGE 873 
Length of male 7.3-7.9 mm, of female 7.6-7.9 mm. Head moderately 
produced, median length of crown varying from slightly less than one-half to 
slightly more than one-half interocular width and from three-tenths to slightly 
more than one-third transocular width, ocelli located on a line between an- 
terior eye angles, each slightly closer to median line than to adjacent anterior 
eye angle, broad median area of crown punctate, the punctations lenticular or 
changing to longitudinal rugae on posterior half, dorsal surface of ocellocular 
area obliquely rugose anterolaterad of ocellus on each side; antennal ledges 
with anterior margins oblique and convex in lateral view; face without a len- 
‘icular sclerite bordering lateral clypeal suture on each side below eye, clypeus 
with muscle impressions not very distinct. Thorax with pronotal width equal 
0 transocular width of head, lateral pronotal margins convergent anteriorly, 
lisk transversely rugose, scutellum transversely rugose behind transverse 
iulcus; forewing with veins distinct, outer anteapical cell with one or a few 
‘supernumerary crossveins in some specimens, outer apical cell usually with 
yne supernumerary crossvein; hindleg with length of first tarsomere approx- 
mately equal to combined length of two more distal tarsomeres. Male pygofer 
noderately produced, with posterior margin as described above in G. delongi, 
1. Sp., without processes; plates extending posteriorly as far as pygofer apex,
