and my recent restudy of this specimen has substantiated this view, 
so a rather wide Tertiary distribution of these insects is indicated. 
At the present time the family is restricted to southern Africa, 
Asia (Burma, China, Formosa), and Australia. In the most recent 
revision, Kimmins (1939) treated the living species as representing 
eight genera which are distinguished principally on the basis of rather 
small differences in such details as the pattern of anastomoses between 
M and Cu in the fore wing ? the pattern of maculation of the wings, 
and in the relative widths of the fore and hind wings. 
In the Baltic amber the family has, until now, been known only 
from the single specimen described as Propsychopsis helmi by Kruger 
(1923), although as noted above one of Hagen’s larval specimens 
turns out to have been a psychopsid. A total of six specimens, 
including two larvae, is available for the present study. The four 
adults seem to fit Kruger’s description of Propsychopsis and although 
these specimens ishow a number of similarities to several living genera, 
the differences between the living and fossil forms are sufficient to 
retain Kruger’s generic name. I shall here redescribe, and somewhat 
redefine, Propsychopsis based on Kruger’s account and on the new 
material now available.

Description . Head lacking ocelli, but vertex with three raised, 
wart-like protuberances bearing long setae, the median protuberance 
smaller than the lateral two; head with a trace of a median sulcus 
posteriorly. Pronotum about as long as broad, anterior margin 
nearly straight, rounded at lateral corners. Male: prothoracic tibiae 
not swollen; ectoprocts posteriorly produced (figs. 10, 11); medi- 
uncus elongate. Female: ninth gonocoxites with a stylus. 
Fore wing (figs. 8, 9) : 30-40 costal veinlets, mostly single forked, 
a few twice or unforked. Rs with 12-18 branches, mostly unforked 
before marginal twiggings. Basal piece of MA (fig. 8, b) oblique, 
fusing with stem of R for a very short distance and separating from 
stem of Rs near its base; a nygma present in small cell basad of 
basal piece of MA (fig. 8, n). MP (fig. 8, MP) with basal fork
