 the overhanging sides of the pronotum; basal costal aiea stiongly and thickly punctate and somev.hat 

 coriaceous; five apical and two discoidal cells; third apical cell nearly circular and petiolate; apical Um- 

 bus narrow. Hind wings with four apical cells and no discoidal cell. Legs simple ; posterior tarsi 

 longest.

Polyglyptodes Fowler, B. C. A. H : 128 (1896). 



Characters : Medium sized, more or less triangularly shaped insects with elevated, flattened 

 bodies, compressed frontal horn, strongly ridged pronotum and with tegmina only about one-fourth 

 exposed. Head subtriangular; base arcuate; eyes ovate; ocelli large, prominent, equidistant from each 

 other and from the eyes and situated on a line drawn through centers of eyes; inferior margins of genre 

 sinuate; clypeus extending for half its length below inferior margins of gense with its lateral maigins 

 continuing the facial line made by the margins of the genae. Prdnotum strongly elevated, considerably 

 compressed. tectiform; porrect laterally flattened frontal horn arising from in front of humeral angles and 

 extending forward and upwaid, with the tiprounded; metopidium keeled, about as broad as high; humei- 

 al angles strong, short and blunt; median carina strongly percurrent ; dorsum depressed behind frontal 

 horn, then arcuate. then gradually sloping to the posterior apex which is acute andextends a littlebeyond 

 the tips of the tegmina; sides of the pronotum strongly, longitudinally ridged. Tegmina three-fourtlis 

 covered by the overhanging sides of the pronotum; hyaline or slighlly clouded; basal costal area punc- 

 tate; iive apical cells; one discoidal cell; apical limbus moderaie. Legs simple; hind tarsi longest.
