and slightly sulcate; the portion below the ocellus indistinct, a 

 little broader than that above, expanding below and slightly sul- 

 cate ; lateral carina indistinct, parallel ; face somewhat oblique, 

 narrow. Eyes oblong, ovate, oblique. Antennae extending about 

 one-fourlh their length beyond the pronotum, robust, very sliglitly 

 depressed, and apparently enlarged toward tlie apex. Front lobes 

 of the pronotum rounded, sub-cylindrical; lateral carinne obsolete 

 on the front lobes, obtuse on the posterior lobe ; median carina is 

 but an indistinct line ; three transverse incisions distinct, but not 

 profound, the posterior one situated a little behind the middle; 

 the posterior border is regularly rounded, nearly semi-circular ; 

 the posterior lateral margin curves inward but makes no angle ; 

 the posterior lobe is distinctly broader than the head. 



Elytra of moderate width ; wings rather narrow, both extend 

 slightly beyond the abdomen. The abdomen is enlarged and 

 deep at the base ; the valves of the ovipositor slender and acute. 

 The posterior femora are quite slender, l)eing but slightly enlarged 

 at base ; posterior tibia? cylindrical. The body and legs more or 

 less covered by small hairs. 



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

 showing the original color to have been green, probably liglit pea- 

 green, which is almost entirely uniform on the head, tliorax, 

 elytra, and legs, without spots. The antennae are dusky at the 

 tips. There is a slight rufous tinge on the posterior lobe of the 

 pronotum, and base of the elytra ; the apical portion of the latter 

 is translucent; wings pale yellow at base pr(;bal)ly greenish-yel- 

 low in the living individual with a moderately broad fuscous 

 band across the disk, apex transparent with dark nerves. Spines 

 of the posterior tibia yellowish, very slightly or not at all tipped 

 with black.
