Genus Arribalzagia. Sp 
The larger uncues of the first pair of legs have, besides the tooth in the 
middle, a second one at their base. 
Habitat.—East Africa: Dar es Salaam and Mballa Plain, south of 
Victoria Nyanza. South-west Africa: Franzfontein.” 
Remarks.—1 have not seen this species; but, judging from 
the description, it is very distinct. It differs in two important 
points from its nearest ally, P. cinereus, Theobald. First, because 
the femora and tibiae of merus have light. spots and stripes 
which never occur in e?nereus; and secondly, the pale fringe 
spots are very broad, but in cinereus they are narrow. Beyond 
this I can find no difference at all. In my description of 
cinereus I omitted to mention the two small black basal spots 
shown now in Plate I. 
Tt does not in the least resemble my Cellia Pharoensis, as Donitz 
says. Nor does it resemble Loew’s costalis. How it could bear 
resemblance to both of these totally different insects I fail to 
comprehend, and I cannot but feel that Dénitz must have been 
thinking of some other insect when he made such a statement.
