CICADELLINAE : PART I. PROCONIINI 89 



related to Depanana from which it may be separated by the form of the 

 aedeagus and by the male plates, which are not fused as in Depanana. 

 D. sulcata (Signoret) has been taken in numbers from sugar cane 

 in Venezuela.

 punctata Germar, by monotypy. 



Length 11-16 mm. 



Head moderately produced, with median length equal to or exceeding 

 interocular width, anterior margin slighdy elevated and carinate; 

 ocelli located on a line between anterior angles of eyes, each slightly 

 closer to median line than to adjacent eye angle, with an M -shaped 

 elevation bordering posterior margin, with a short longitudinal carina 

 laterad of each ocellus, with a median fovea which is broadened 

 anteriorly, disc without pubescence; antennal ledges with a longitudinal 

 sulcus, in lateral aspect carinate dorsally and with anterior margins 

 steeply declivous; clypeus depressed beneath apex of head, muscle 

 impressions distinct; face finely pubescent below; clypellus not pro- 

 duced, its contour continuing profile of clypeus. 



Thorax with pronotal width less than or equal to transocular width 

 of head, lateral margins convergent anteriorly or parallel, posterior 

 two-thirds of pronotal disc transversely rugose and punctate, posterior 

 margin concave, with complete dorsopleural oblique rectilinear 

 carinae; scutellum usually transversely striate on posterior portion.
