MEMBRA CIDJE. 
251 
dark ochreous-brown. Posterior horn uniformly cylindrical, undulating, or sinuous, 
without rugosities. Underside, part of the scutellum, and the legs sordid ochreous. 
Abdomen ringed with dark brown. Tegmina sordid ochreous-yellow, with a 
blackish apical margin. A costal spot and a short brown bar from the lower 
marginal edge, also black. Nervures brown and strongly marked. 
Though somewhat aberrant from the genus, I include it provisionally as before, 
partly from the character of the pronotal horn. 
Size, 10 x 6 mm. 
Habitat. —Stephansort, German New Guinea. 
Genus : RABDUCHUS* n.g. 
RABDUCHUS GNOMON, n.s. 
(Plate LVII. figs. 4, 4a.) 
Colour dark brown, glabrous, and punctured. Metopidium rising perpendicularly 
and tumid, or else slightly inflated behind the dorsal part of the pronotum. 
This suddenly ends in a narrow and cylindrical horn, which is straight and carried 
nearly to the apex of the tegmina. Tegmina warm brown, pale, showing five 
apical oblong areas and several discoidal areas, but the neuration is difficult to 
follow. 
The female is larger than the male, and is hirsute. The male has a small conical 
hump on the back of the abdomen. 
Size, 6x4 mm., $ ; 8 x 4 mm., $. 
Habitat .—Old Calabar, and the Cameroons, W. Africa. 
This genus seems to be allied to the genera Ischnocentrus, Psilocentrus, and 
Phaulocentrus of Fowler. Their chief difference consists in the absence of supra- 
lmmeral processes, or at least their suppression of the same. They also are described 
as containing American species only. 
Genus : PEDALION, n.g. 
Suprahumerals short and truncated, or squarely cut off at their tips. Pronotum 
continued backwards as a long posterior horn, straight at its inferior edge, but 
expanded at the end into a flat triangular blade having a fanciful resemblance to 
a boat’s rudder. Over the dorsum this process rises into a swelling or dentation. 
The tegmina have broadly developed limbal borders at their apices. 
Hitherto the species seem to be confined to the African continent.
