42 Mr. R. Shelford on some 
Paraplecta ethiopica, sp. nu. 
¢. Castaneous, smooth, nitid ; vertex of head not covered 
by pronotum ; ocelli, apex of clypeus, mouth-parts, and 
antennze testaceous ; minutely punctured. Pronotum trape- 
zoidal, with rounded posterior angles, minutely punctured ; 
posterior margin truncate, exposing the scutellum. Tegmina 
semicoriaceous, barely reaching apex of abdomen ; eleven or 
twelve costals ; discoidal field reticulate, anal vein impressed ; 
eight axillaries. Wings with a large apical reflected area, 
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 venule 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. 
2. 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. 
dg. Total length 9 mm. ; length of tegmina 8 mm. ; pro- 
notum 3 mm. x3°2 mm. 
2. Total length 11 mm.; length of tegmina 7 mm.; pro- 
notum 8°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. ethiopica 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 Cuoristima, Tepper.

(1897). 
Kirby in his ‘ Synonymic Catalogue of Orthoptera’ (1904), 
following Brancsik, places Aphlebidea in the Ectobine; but 
as the femora are unarmed beneath and a triangular apical 
field is present in the wings, the genus falls naturally into the
