posterior tibiae cylindrical. The body and legs more or less covered with 

 • small hairs. 



Color (after immersion in alcohol). — Dull greenish-yellow, showing the 

 original color to have been green — probably light pea-green — which is almost 

 entirely uniform on the head, thorax, elytra, and legs, without spots. The 

 antennae are dusky at the tips. There is a slight rufous tinge on the poste- 

 rior lobe of the pronotum and base of the elytra ; the apical portion of the 

 latter is translucent. Wings pale-yellow at base — probably greenish-yellow 

 in the living individual — with a moderately broad fuscous band across the 

 disk ; apex transparent, with dark nerves. Spines of the posterior tibise yel- 

 lowish, very slightly or not at all tipped with Ijlack. 



Dimensions. — 5 Length, 1.25 inches ; elytra, 0.80 inch ; posterior femora, 

 0.60 inch ; posterior tibiae, 0.65 inch ; pronotum, 0.25 inch.

Body medium size or small, elongate. Head sub-conic in front; face 

 more or less sloped obliquely backward and under toward the breast ; vertex 

 in front of the eyes somewhat prominent, horizontal ; the lateral foveolae 

 (when present) are linear ; when they are absent the margins of the vertex 

 are obtuse. The frontal costa is generally sulcate throughout, or from the 

 middle ocellus downward ; lateral carinas distinct. Eyes gub-rotund or sub- 

 angulate. . The antennae generally exceed the head and pronotum in length, 

 and are sub-compressed or sub-cylindrical, clavate in the male of one species. 

 The pronotum has the disk more or less flattened, seldom gibbous; the sides 

 somewhat compressed; the front margin truncate; the hind margin obtuse- 

 angled or obtusely rounded ; the three carinas usually distinct, but not elevated 

 — the median straight entire, the lateral straiglit or curved inward at or in 

 advance of the middle. Elytra and wings sometimes abbreviated, sometimes 

 as long or longer than the abdomen, generally narrow. Legs slender; the 

 posterior femora somewhat elongate, and but moderately enlarged at the base. 

 Prosternum unarnied ; narrow.
