Rare. A small brownish species with a weak jiyramidal crest. The 

 crest is darker than the remainder of the pronotum. The species has 

 been taken on white oak and on basswood. Nothing is known of its 

 habits or of its life history. Commoner in higher parts of the basin than 

 elsewhere, in regions where older trees abound. 



Technical description. — Small; mottled greenish brown; crest low and rounded; posterior 

 process not reaching tips of tegmina; tegmina smoky hyaline, tips broadly clouded. 



Head much wider than long, greenish, finely punctate, sparingly pubescent, sutures well 

 marked; base regularly sinuate; eyes very prominent, protruding, brownish; ocelli small, 

 pearly, distinct, slightly protruding, much nearer to each other than to the eyes; clypeus 

 small, sinuately rounded above, tip extending only slightly below inferior margin of face. 



Pronotum very irregularly punctate, some punctures coarse and deep, others fine and 

 shallow, sparingly pubescent; metopidium low, greenish, median carina very prominent 

 and brown, yellowish depre.ssion above each eye; humeral angles not prominent, rounded; 

 dorsal crest low, not so high as its width at base, darker in color than remainder of pronotum, 

 posterior margin pale; posterior process short, hairy, longitudinally striate, sharp at tip, 

 not reaching apices of tegmina. 



Tegmina hyaline, veins very prominent, bases weakly punctate, apices broadly clouded 

 with brown. Legs and undersurface of body concolorous fuscous; abdomen brown; tibiae 

 spined with minute hairs. 



Length to tips of tegmina, 8 mm.; width 3.5 mm.

Rare. A rather large, heavy-bodied species, with the crest very much 

 reduced. Has been found only on the highest parts of the hills, on various 

 species of oak. The nymphs of the species have never been recognized, 

 and nothing is known of the habits or of the life history. Only a few 

 specimens have been taken locally. 



Technical description. — Short, thick, heavy body; crest reduced to a rounded lobe; posterior 

 process not reaching ape.x of abdomen; tegmina smoky hyaline tipped with brown. 



Head wider than long, yellowish with black punctures and scattered white pubescence, 

 center of each vertex depressed and broadly black; base regularly sinuate; eyes prominent, 

 brown; ocelli prominent, somewhat protruded, margins white, nearer to each other than to 

 the eyes; clypeus subtriangular, depressed at base, sutures distinct, hirsute. 



Pronotum closely punctate, sparingly pubescent, greenish brown mottled with ferruginous; 

 metopidium only slightly convex, smooth depression above each eye, median carina prominent, 

 black interrupted with pale; humeral angles not prominent, triangular, rounded at tips; 

 dorsal cre.st low, rounded, gradually sloping before, steeper behind, margins slightly flattened; 

 pcsterior process short, heavy, blunt, tectiform, longitudinally striate, not reaching apex of 

 abdomen and extending only about one-third the distance between the internal angles and 

 the tips of the tegmina. 



Tegmina smoky hyaline, bases punctate, tips clouded with brown, veins heavy, inclined 

 to punctuation. Undersurface of thorax fuscous, abdomen brown. Legs mottled with 

 green and brown; tibiae hairy; tarsi ferruginous. 



Length 9 mm.; width 4 mm.
