The antennae of the nnUe are scarcely so long in this species as in 

 tlic others; it differs decidedly from E. concinnm in the bent and narrow 

 cerci as well as in the more nearly quadrate interspace between the 

 mesostprnal lobes of the male; from A*, pihsm, to which It seems more 

 nearly allied and for which 1 at first mistook it, it differs in the cerci of 

 the male, which do not narrow before the n.iddle, in being a smaller 

 iiibcct, besides having a duller coloring with more contrasted markings, 

 to judge from JStul's description.

I iiave not see", this species, and acco'-dingly give SttlFs description, 

 englished. The descripiion is mainly a comjjarative one, the basis of 

 comi)ari8()n being Aidemona azteca, next which Stal jdaced it, in the 

 same section of Pezotettix. 



Olivaceous; legs yellowi.sh olivaceous ; hind tibiae greenish olivaceous, 

 the base and geuiculation proper of the hind femora black; tegmiua 

 rudimentary. Length of male 10 mm. 



J/^f/t'.— Inters J, \ce between mesosternal lobes a little longer than 

 broad, ^ith parallel sides, much narrower than the lobes themselves; 

 metasteinal lobes subcont^ ^uous; eyes large, rather convex; apical 

 margin [of the i>ronotumJ gradually and obtusely sinuate, slightly 

 emarginate in the middle, destitute of a lobe; supraanal plate fur- 

 nished with a gradually narrowing sulcus, extending beyond the 

 middle of the plate; cerci gently curved, compressed and rather broad 

 throughout, before the middle slightly narrowed; subgenital plate 

 short, very strongly recurved; abdomen posteriorly tumescent and 

 somewhat recurved. 



Distinguished from Aidemona azieca by the front and prozona less 



tnsely punctate, frontal costa obtusely subsulcate, narrower between 

 e antennae, the sides parallel but slightly narrowed at the base, the 

 i|terspace between the eyes narrower, the disk of the pronotum 

 looth, abbreviate and truncate anteriorly, the metazona about half 

 long as the prozona, tegmma rudimentary, widely separated, ellip- 

 jal. extending slightly beyond the median segment, shorter than the 

 ^oiiotum, the abdomen blunter at tip, posteriorly more tumid and 

 ifcmved, the cerci broader, the last dorsal segment of the abdomen
