CICADELLmAE : PART I. PROCONIIISri 157 



Thorax with pronotal widtli less than transocular width of head, 

 lateral margins parallel, disc punctate, without conspicuous pubescence; 

 scutellum obscurely striate in posterior half; otherwise as in Abana. 

 Forewing with membrane including all of apical cells, clavus incom- 

 pletely punctate, with more than four apical cells, the base of the fourth 

 slighdy more distal than base of third, otherwise as in Abana. Hindwing 

 as in Abana. Hindlcgs with femoral setal formula 2:0:0; otherwise as 

 in Abana. 



Male genitalia: Pygofer with a dorsal projection near midlength of 

 dorsal margin, with a number of small macrosetae extending from base 

 of plate to pygofer apex, without processes. Plates separate throughout 

 their length, extending as far posteriorly as pygofer apex, triangular, 

 with a number of small macrosetae on disc and a number of microsetae 

 laterad of these. Style extending farther posteriorly than apex of 

 connective, with distinct preapical lobe, apex somewhat foot-shaped 

 with the toe directed mesally, with a few lateral anteapical microsetae. 

 Connective Y-shaped, with arms not widely divergent, stem expanded 

 at apex. Aedeagus symmetrical, with a pair of elongate conspicuous 

 dorsal processes between which is an unpaired process, gonopore very 

 large. Paraphyses elongate, slender, symmetrical. 



Female abdominal sternum VII abruptly narrowed near midlength 

 and produced in a quadrate process which is tidlobed at its apex. 



This genus is known only from the type-species, which is very rare 

 in collections. Specimens have been examined from French and British 

 Guiana and "Amazonas." Omagua is related to Deselvana, new genus, 

 from which it differs in its less produced head and its shorter aedeagal 

 shaft with the very large gonopore. 



55. Genus RHAPHIRRHINUS Laporte 



Figure 148 

 Rhaphirhinus Laporte, 1832d:413. Type-species: Fulgora adscendens Fabricius, 



which is a junior synonym of [Cicada] phosphorea Linnaeus, by original 



designation. 

 Rhaphidorhinus St^l, 1869a:62 (invalid emendation). 



Length 12-17 mm. not including process of head. 



Head strongly produced, median length (without process) exceeding 

 transocular width, gradually or abruptly narrowed apically and with 

 a slender, elongate, curved apical process extending anteriorly and 

 dorsally, disc with a narrow full-length median fovea; antennal ledges 

 with a longitudinal fovea, in lateral aspect carinate dorsally; clypeus 

 convex except for slight concavity below base of process, muscle 

 impressions not conspicuous; otherwise as in Deselvana, new genus.
