570 PROCEEDINOS OF THE NATIONAL MUSEUM. vol. 46. 



this, but differs in the points mentioned in the synopsis of the genera. 

 After an examination of the original specimens in the United States 

 National Museum, I would add the following to the above description: 

 Frons distinctly broadened above clypeus; median carinae forked a 

 little below apex of head. Calcar long, triangular-prismatic, faces 

 flat, acute at tip, finely pubescent; liind tibiae with four lateral spines. 

 Male genitalia resembling somewhat Eucanyra, but narrower and 

 longer.

Genus DICHONEURA Lethierry. 



Lethierry described this genuS as f oUows : 



Vertex triangular, as long as broad, produced in front before eyes, base and sides 

 carinate, elevated, apex obtusely angled; frons three times as long as broad, tricarinate ; 

 lateral carinse slender, sharp, median broad, convex. Antennae very short, joints 

 equal in length, each as thick as long, not extending beyond lateral frontal carina; 

 terminal seta long. Elytra long, much longer than abdomen, apex rounded. Hind 

 tibias trispinose and numerous setae and spines between; calcar double, inner one small, 

 trifid; the outer, simple and terminal. 



Type of genus. — Diclioneura simoni Lethierry. 



Accordmg to Lethierry this genus is "near Delphax Fabr," It 

 differs sharply m the hind tibiae, however, iromXihurnia, havuig three 

 lateral spines instead of two, and the calcar, according to the descrip- 

 tion, is quite unique. It is probably cultrate with three large teeth 

 on hind margin, giving the appearance of being trifid. For the 

 present, at least, I have related it to Proterosydne, another tropical 

 genus.

 lateral carinas straight; scutellum tricarinate; legs long; hind tibiae
