between them arises a straight blackish process; their 
appendages filiform, black, curved downward.

In coloration this considerably resembles the Asiatic 
L. umbrina, Selys. No doubt it is allied to ZL. dcterica, 
Gerst., from Mombas on the Zanzibar mainland, which was 
based on a single mutilated example; but, according to the 
description, the latter cannot be identical, it being smaller, 
paler, with longer pterostigma, the longitudinal nervures 
yellow, no black lines on the legs, &c.
