useless for generic identification, as the author did not define

> t For the study of genera represented in Europe a careful study has 
been made of the European genera representatives, as far as they were 
present in my collection. 
Unless where otherwise stated, the descriptions of the genera are made 
of the type of each genus. 
In the description of new species Ridgway’s “ Color Standards and 
Color Nomenclature,” 1912, has been used, and the figure behind the 
colour indicates the plate of this most useful work. I think it a pity that 
so very little use is made by Lepidopterists of standard colours, which 
enable one to identify colours with certainty. 
All measurements given in the specific description include the cilia, 
and are measured from tip to tip of the fore wings with the specimens 
set in the Continental way. 
I also venture to give a phylogenetic table, showing the affinity of 
the South African genera, as 1 understand them. 
I distinguish three distinct branches, of which Bazisa and Redoa are 
the most primitive, while the third form, from which the Dasychira- and 
Lymantria- branches have come, together with the ancestor of these three 
branches, are unknown to me. 
The Bazisa-brsmeh has the palpi with two joints only, but all its 
genera are very primitive in neuration ; Cimola must have given rise to 
Lepidopalpus and Olapa — the former also has the process of the fore tibia 
two-jointed;* Olapa gave rise to Pirga and Bracharoa. 
Redoa has three-jointed palpi, which become reduced in Creaga and 
all genera originating from this genus ; the two branches, Lacipa and 
Bicelluphora , are most peculiar for their vein 11 of fore wing, which is 
free and from the upper median in all other genera of the South African 
Lymantriadae . The branches from Creaga come very close to each other. 
The third branch is most developed specifically, many genera being 
very large. 
The Lymantria- branch is best developed generically and contains 
genera of the highest development. It splits into two branches, the 
Polymona-Aclonophlebia- branch (near which come perhaps the two genera 
that I have not been able to study) and the Ornit/topsycJie-hidhiich. From 
I cannot account for Bazisa having the process without this second joint.
