CICADELLINAE : PART I. PROCONIINI 43 



a median fovea, without pubescence, antennal ledges not fovcate, 

 clypeus flattened or very slightly depressed medially. Pronotum without 

 conspicuous coarse rugae, scutellum minutely, transversely striate on 

 posterior half. Forewings opaque, without a network of veins in clavus 

 and basal half of corium. Male pygofer deeply emarginate basiventrally ; 

 plates not extending as far posteriorly as pygofer apex ; style extending 

 about as far posteriorly as connective, apex curved slightly laterad, 

 rounded at tip; connective Y-shaped; aedeagus with shaft short, widest 

 at midlength, ventral margin slightly concave in apical half, without 

 processes other than long ventral processes which arise basiventrally, 

 extend in an arc posterodorsally, gready exceeding apex of shaft, 

 and are fused through more than the basal half their length. Female 

 abdominal sternum VII with posterior margin produced only slightly 

 more at middle than laterally, slightly concave medially, the posterior 

 margin appearing sinuate. Crown, pronotum, and scutellum dull 

 yellow, with indistinct dull brownish submarginal bands along lateral 

 pronotal margins. Foi'ewings opaque white, with a few black points 

 in corium. 



Holotype male with label "F 33031912; Barro Colorado C.Z./ 

 Ill 18 1933" (AMNH). A number of additional specimens of both 

 sexes have been examined from the Panama Canal Zone; British 

 Honduras; Ecuador; and from Callanga and Tingo Maria, Peru. 



This species is named in honor of Dr. F. S. Blanton whose collecting 

 activities in Panama have done much to increase our knowledge of the 

 fauna of Central America.

Figure 20 



Length of male 18.5 mm.; of female 20 mm. Head with clypeus 

 slightly depressed medially. Male with style not curved apically; 

 aedeagal shaft short, broad, truncate apically but with dorsal portion 

 of apical margin produced slightly posteriorly. Female abdominal 

 sternum VII as in D. schmidti Melichar but longer. Other structural 

 characters as in D. blantoni, new species. Color as in blantoni, but with 

 lateral pronotal brown markings extending onto head along inner 

 margin of each eye and including the antennal ledges, the lateral 

 pronotal coloration in some specimens joined in basal half of pronotum 

 by a concolorous transverse band and joined along posterior pronotal 

 margin delimiting a circular median pronotal yellow spot; forewings 

 with a few black points in basal half of corium and an oblique black 

 line near midlength of corium.
