Four representatives of this genus are reported from South 
Africa, only one of which is found in the Transvaal, 0. savignyi 
caecus. 0. savignyi pavimentosus is found in German South-West 
Africa, where caecus is also supposed to exist. 0. talaje capensis 
is limited in its distribution, being confined to the islands off the 
west coast of Cape Colony where penguins are abundant. 
The four varieties may be separated by the following key: — 
Adults and Nymphs. 
A. Body short, oval; widely rounded at both extremities;, 
several teeth upon tarsi and article Y of legs. Rostrum 
without prominent lateral cheeks to form a partial hood for 
it. 
B. Eyes present. 
C. Teeth upon tarsi and article Y of legs, well separated, 
higher than wide and rounded ... ... savignyi. 
CC. Teeth upon tarsi and article Y of legs, closer 
together, wider than high and more quadrilateral 
in outline ... ... savignyi pavimentosus - 
BB . Eyes absent ; teeth on coxae as in savignyi 
savignyi caecus. 
A A. Body elongate and narrow, pointed on the anterior end; 
rostrum with prominent lateral cheeks, which partially cover 
it ; no teeth upon coxae or article Y of legs 
talaje capensis. 
Larvae (only known of two species). 
A. Length 1.66 mm.; width 1.3 mm. .. .. savignyi caecus.. 
A A. Length 1 to 1.5 mm.; width 0.75 to 1 mm. 
savi gnyi pavimentosus ..
