HOMOPTERA 



the face. Pronotum elevated in a dorsal crest which consists of two distinct lobes, a rounded anterior 

 lobe and a lower, angulate posteiior lobe ; metopidium convex and sloping, broader than high ; median 

 carina strongly percurrent; humeral angles broadly flattened and produced into trianguiar, auriculate 

 extensions; sides of pronotum punctate, feebly and irregularly ridg«d, extended downward to cover 

 about half of the tegmina; posterior process strong, heavy, tectiform, gradually acute, reaching just 

 about to thetips of the tegmina. Tegmina hyaline; about half exposed; basal and costal areas strongly 

 punctate; five apical and two discoidal cells; apical limbus well developed. Legs simple, subcylindrical ; 

 hind tarsi longest.

124. Genus TELONACA Ball 



Telonaca Ball, Pioc. Biol. Soc. Wash. XXXI : i. 27 (1918). 



Characters : A genus of the Telamona group, distinguished from the type genus of the tribe by 

 the high, sinuate, somewhat foliaceous crest arising directly above the metopidium. Head subovate, 

 much wider than high ; base arcuate and strongly sinuate; eyes ovate, twice as wide as high; ocelli large, 

 conspicuous, nearer to each other than to the eyes and situated about on a line drawn through centers 

 of eyes ; inferior margins of genas weakly sinuate ; clypeus extending only a very little below the inferior 

 margins of the genae and continuing the rounded apical outline of the face made by the genae. Prono- 

 tum elevated in a strong, high crest arising from the metopidium, its frontal margin anterior to the humer- 

 al angles; metopidium triangular; median carina percurrent; humeral angles produced into broad. 

 sharp, auriculate extensions; sides of pronotum punctate, the posterior half bearing longitudinal ridges, 

 and extended downward to cover about one-third of the tegmina. Tegmina hyaline; about two-thirds 

 exposed; basal costal area weakly and coarsely punctate; five apical and two discoidal cells; apical limbus 

 well developed. Legs simple; hind tarsi longest.
