Paraplecta cethiopica, sp. u. 



(^ . Cnstancnus, smoolli, nitifl ; vertex of head not eovcred 

 by pronotuin ; oeelli, apex of clypeus, inoutli-parts, and 

 antennae testaceons ; minutely punetured. Pronotum trape- 

 zoidal, with ronnded posterior angles, minutely punetured ; 

 posterior margin truncate, exposing the scutellum Tegmina 

 semieoriaeeous, barely reaching apex of abdomen ; eleven or 

 twelve costals ; discoidal field reticulate, anal vein impressed ; 

 eight axillaries. AVings with a large apical rellectcd are-i, 

 two fifths of total wing-length, its basal margin obtusely 

 angled; costals highly irregular and obsolescent ; median vein 

 consisting of two parallel branches, with one or two trans- 

 verse venulse connecting them ; ulnar vein with seven branches. 

 Abdomen castaneous above, supra-anal lamina produced ; 

 abdomen rufo-castaneous below, subgenital lamina asym- 

 metrical with one style (the left) ; cerci short, acuminate, 

 4-jointed, Legs testaceous ; femora spineless, tarsal claws 

 without arolia. 



? . Similar to ^ , but larger, tegmina and wings (when 

 folded) not extending beyond the sixth abdominal tergite ; 

 supra-anal lamina produced quadrately; subgenital lamina 

 ample, produced, narrowed posteriorly. 



^. Total length 9 mm. ; length of tegmina 8 mm. ; pro- 

 uotura 3 mm. x 32 mm. 



? . Total length 11 mm. ; length of tegmina 7 mm.; pro- 

 notum 3'5 mm. x 3'8 mm.

 Museum). 



The species can readily be distinguished from P. pallipes, 

 Stal, by the wing-structure : in Stal's species there is a con- 

 spicuous triangular apical area which in P. ofthiopica has 

 become extended to form an apical reflected area ; the 

 venation is very similar in both species, but in pallipes the 

 costals are better marked and the rami of the ulnar vein are 

 more numerous, the double median vein is common to both 

 species. 



Genus Choristima, Tepper.

Kirby in his ' Synonymic Catalogue of Orthoptera ' (1904), 

 following Brauesik, places Aphlebidea in the Ectobinae ; but 

 as the femora are unarmed beneath and a triangular apical 

 field is present in the Avings, the genus falls naturally into the
