 combined head and pronotum, the joints flattened, on the apical half 

 punctate. Disc of pronotum nearly flat ; the median carina distinct 

 but slight, broken once in the middle ; lateral carinae distinct through- 

 out, sinuate, at first approximating a little and then diverging 

 greatly in passing backward ; posterior margin bent at more than a 

 rioht anfle ; tegmina slender but not extending much beyond the 

 bodv; wings with the principal cells of the front area longer than 

 broad, pellucid with a more or less fuscous tip ; lower interior apical

 olivaceous tinges on the sides, heavily mottled with yellowish and 

 blackish in front (excepting the frontal costa) and about the mouth 

 parts • extreme basal joints of antennae yellowish, beyond dusky, 

 darkening toward the tip, joints 4-5 minute, but the sixth longer than 

 broad. Pronotum blackish above, faintly and inconspicuously flecked 

 with dull yellowish, the sides mostly dull yellowish with a blackish, 

 longitudinal, irregular band below the middle ; tegmina blackish 

 fuscous, the veins blackish, a few pale dots indistinctly seen in a row
