Psyche 
[June 
possibly Megapsy chops, Tillyard’s account docs not mention or 
figure this vein) retains a longitudinal orientation of this vein 
although in Magallanes, Silveira , and W ernzia it is distinctly oblique 
in its placement. In Psychopsis the transverse orientation of the 
basal piece is so pronounced that it resembles a cross vein and in 
Bcihnkes it is absent altogether. Finally, a number of living forms 
retain relatively broad hind wings, although a reduction in width 
has occurred in the species of Silveira and in the Australian Bahnes 
gallardi Tillyard. 
Contrary to Kruger’s belief in a close similarity between Pro- 
pyschopsis and Psychopsis, I believe that the species of this latter 
genus are the quite specialized products of a long, isolated evolu- 
tionary history of their own and are only distantly related to the 
living species outside of Australia and to Propsychopsis. In addi- 
tion to the specialized structural features of Psychopsis noted above, 
the complex, colorful, and very beautiful transverse fasoiate patterns 
of the fore wing and the large dark spot behind the terminal 
anastomosis of the vena triplica of the hind wing of these species 
should also be noted. Both of these features are shared with 
Megapsychops and the hind-wing spot also occurs in Magallanes 
and TV ernzia. These patterns are quite unlike the mottled, splotched, 
or irrorated wing patterns of the living species outside of the 
Australian Region and of Propsychopsis. 
In its pattern, small size, unspecialized condition of MP and 
CuA in the fore wing and in its broad hind wing, Propsychopsis 
approaches the Asiatic species of Balmes very closely, although, as 
I have noted, Bahnes shows the specializations of the loss of the 
median vertex tubercle and the base of MA in the hind wing neither 
of which are found in Propsychopsis. The African gen-era Noto~ 
psychops and Silveira show the more generalized state of these two 
features, but these genera have such additional specializations as 
anastomoses between the branches of MP (or between MP2 and 
CuA in Notopsychops) and, in Silveira, a reduction in the width 
of the hind wing. Barring the discovery of additional fossils or 
annectant living forms, I do not believe that a more precise con- 
clusion as to the phylogenetic relationship between Propsychopsis 
and the living species is now possible. 
The four adult specimens now before me clearly comprise two 
species. I am, however, unable to identify either of these as Kruger’s 
P. helmi from his very general description and, as I have been 
unable to locate his type specimen for restudy, I am describing each
