100 ORTHOPTEKA. 



ACHKOBLATTA*, Sanaa. 



Achroblatta, Saussure, Societas Entomologica, 1893, p. 67. 



Antennae subgraciles. Caput minutum, planatum, obtectum vel vix prominulum, oculis modice remotis. 

 Pronotum eoriaceo-rugulosum, margine postico quam margo anticus nmlto magis arcuato, rotundato- 

 producto ; disco utrinque depresso ; parte antica supra caput fornicata ; marginibus lateralibus haud 

 deflexis. Elytra et alae sensim ut in genere Panchlora venosa. Elytra subcoriacea, dense punctulata, 

 parallela, apice haud attenuata. Alae apice rotundatae. Femora subtus spina apicali nulla. Lamina 

 supra-analis transverse quadrata, incisa vel bilobata. — Insecta picta, pallide colorata. 



This genus approaches Panchlora, but differs from it in its smaller head, in the 

 pronotum being widest before the middle, and in the middle and hind femora being 

 without apical spines on their lower borders.
