CICADELLINAE: PART 2. NEW WORLD CICADELLINI 849 
apically, paraphyses with bases of rami not separated and with the rami ap- 
proximately the same length. Female with apices of second valvulae of 
ovipositor slightly more acute than in A. smithi, n. sp. 
Color of crown, anterior portion of pronotum, and scutellum black, remain- 
der of pronotum brown, crown and pronotum with a number of irregular 
yellow spots, scutellum with a pair of diagonal yellow lines, convergent an- 
teriorly, and a median yellow spot behind midlength; forewing brown with a 
number of irregular yellow spots; face brown with lateral areas of clypeus 
black, and with large yellow spots on clypeus and clypellus, genae and 
propleura brown marked with yellow, remainder of thorax black beneath, 
with few yellow markings, legs brown with irregular yellow spots. 
Holotype male, Real de Arriba, Temescaltepec, Mexico, May 24, 1933 (H. 
_E. Hinton and R. L. Usinger) and one female, same data except date which is

May 31, 1933 (CAS). 
The species is named in honor of the late Dr. Robert Usinger who made 
major contributions to the taxonomy of Hemiptera. A. usingeri, n. sp., differs 
from A. smithi, n. sp., in the characters used in the key. Also, the disk of the 
crown is not concave, as it is in smithi, and the punctures on the disk are 
round.

Length 4.2-9.4 mm. 
Head weakly to well produced, anterior margin subangulate to broadly 
rounded in dorsal view, without a carina at transition from crown to face (ex- 
ception: G. nigrifascia (Walker)), ocelli with location variable interspecifically, 
crown varying from slightly convex to slightly concave, seldom variable intra- 
specifically, with a transverse concavity before ocelli, without a median fovea, 
surface usually with shallow lenticular impressions near middle of disk, or at 
least behind ocelli, punctate also in some species, without setae, lateral 
clypeal sutures extending onto crown and attaining ocelli; antennal ledges not 
protuberant, in lateral view with anterior margins varying from vertical to ob- 
lique and from convex (most often) to rectilinear; median clypeal area 
granular to punctate, usually without a lenticular facial sclerite bordering 
lateral clypeal suture on each side (extremely narrow when present) below 
eye, clypeus convex medially or nearly flattened, muscle impressions distinct 
or not, transclypeal suture usually obsolete medially, clypellus with its con- 
tour continuing profile of clypeus.
