CICADELLINAE: PART 2, NEW WORLD CICADELLINI 933 
than one-half interocular width, and from one-fourth to almost one-third 
transocular width, clypeus broadly and slightly convex, slightly flattened 
medially. Pronotum not or indistinctly transversely striate, scutellum without 
transverse striae behind transverse sulcus; forewing with membrane including 
inner three apical cells; veins distinct. Pygofer with posterior margin very 
broadly convex above and below a very slight apical concavity, with numerous 
macrosetae parallel to posterior and part of posteroventral margins, in ventral 
view each side with a short apical process which is convex anteriorly, its 
posterior portion acute, directed posteriorly, and appearing parallel to its 
complement on the other side, each side also with a shorter angular process 
arising subapically and directed mesally and slightly posteriorly; style not ex- 
tending nearly as far posteriorly as apex of connective, apex oblique and 
slightly concave; aedeagus with shaft long for the genus, with a slender apical 
process arising ventrally, directed ventrad, gradually narrowed and acute 
apically, atrium without processes; paraphyses represented by a very small 
minute median trilobate sclerite very close to apex of connective. Other struc- 
tural characters as in A. krameri, n. sp. 
Color of crown, pronotum, and scutellum yellow, heavily marked with black 
delineating the following major yellow areas: on the crown a broad median 
stripe bisected by a narrow black stripe except apically, and a broad area bor- 
dering each inner eye margin; on the pronotum a median stripe surrounding 
a narrow longitudinal median black stripe in part of its length, and an inter- 
rupted arcuate band on each side converging anteriorly towards the median 
stripe; on the scutellum three basal spots in a transverse row, and a median 
spot behind transverse sulcus; forewings reddish purple, with three spots be- 
tween claval veins, three spots in base of corium, a spot at apex of cell M and 
two spots in apical half of costal cell, yellow, and each at least partially bor- 
dered with black; fourth apical cell black with a pale spot on inner and outer 
margins, apex of membrane smoky-black; face and propleura yellow, variously 
marked with black; legs varying from yellow with variable black markings to 
almost completely black; abdomen dull red. 
Holotype male, El Vergel, Chiapas, Mexico, May 19, 1935 (collector un- 
known), eight males, two females and one specimen without abdomen, all 
labeled “Vergel” or ‘‘Finca Vergel’’, all collected between May 11 and May 
30, 1935, a few bearing label ‘““A. Dampf” or ‘A. Dampf Coll.”; one female, 
“Finca Victoria”, San Luis Potosi, Mexico, June 28, 1935; one female ‘Finca 
Peru”, Chiapas, Mexico, Novernber 7, 1931 (J. Parra), all in DeLong collec- 
tion (OSU); three specimens, environs of Guatemala City, 1908 (R. Guerin) 
and one specimen, Costa Rica, 1921 (Paul Serre) (all MHNP); one specimen, 
Puente Macuilapa, Chiapas, near Los Amates, May 22, 1964 (SPBF); two 
specimens, Piedras Negras, Costa Rica (Schild and Burgdorf); one specimen, 
Higuito, San Mateo, Costa Rica (Pablo Schild); and one specimen labeled 
““Cordova”’ (all USNM). 
Externally, A. dampfi, n. sp., is similar to A. blanchard: (Signoret), but it may 
be separated readily from the latter by its (usually) smaller size, 8.4-10.4 mm, 
compared with 10.4-11.2 mm in blanchardi. The male pygofer processes (fig. 
750p) differ from those of any other species in the genus. Fowler’s (1899d, pl. 
15, figure 27) illustration of A. granulata (Walker) appear to belong to the
