Tue sub-fumily Psychidi, embracing the genera Sterrhopteriz, Psyche, Fumeoa, and Nudaria, contains a set of 
insects of the most singular and anomalous character. This group is especially marked by the entirely wingless 
females, which in some cases are without either legs or antenne, and are, in fact, perfectly vermiform. The curious 
shell-like protection formed by the caterpillars is also very remarkable, resembling that of the Caddis Worm 
family, which, combined with the extraordinary facts recently observed concerning the manner of reproduction 
of this class of Moths, renders them of the greatest interest to naturalists. Their position in the modern 
system of classification has been several times changed, some recent classifiers having placed them along 
the 
section of Bombycide, while closely 
with the Tinee. 
allied genus Sterrhopterix, from the character of the female being till recently unknown, was not placed along 
In former systems they were placed in a 
with them. I have followed the system adopted in the national collection, in which the Psychidw, along with 
Sterrhopterix, appear to be very properly made a distinct sub-family. 
The genus Sterrhopteriz contains two British species, the most robust insects of this group. In S. Nigricans, 
(the Large Chimney-sweep, No. 1), the wings of the male are of a rich soft brown, and rather hairy 
and semi-transparent ; the body is robust and woolly, and the antenne are pectinated. The female (No. 2) 
much larva before its metamorphosis, but of a more maggot-like 
is entirely wingless, resembling a 
conformation. The abdomen is of a dull orange colour, and the thorax and head nearly black. The larva, 
with its house of husks and small sticks, is nearly an inch and a-half long, and sometimes of considerable 
diameter. Its general appearance, however, is much like the smaller larva of Psyche Fusca (No. 44). The other 
English species, S. Opacella, is smaller, and the wings are much paler and more transparent. 
The genus Psyche, the peculiar characteristics of which were known before those of any other of its 
congeners, and has therefore given its name to the whole group, contains but one species.
