larva feeding on mosses and lichens, had been known for 
some considerable time. So long ago as 1864 Mr. McLachlan 
found them in the British Museum collection of cases of 
Caddis worms, and at that time, being only acquainted with 
the case, he was disposed to consider them the work of one of 
the LeptoceridcB. In 1889 Herr Eogenhofer gave the name 
Fumea ? limulus to the case and its contents, and Mr. 
McLachlan agreed from the evidence then adduced that the 
insect wasLepidopterous rather than Trichopterous. Mr. Green 
made drawings of the insect in all its stages, and collected 
the four specimens of the imago now exhibited. Mr. Durrant 
recently described these as Pseudodoxia limulus in the "Ento- 
mologist's Monthly Magazine," referring them to the Depres' 
sariadoe. 
Mr. C. J. Gahan exhibited, for Mr. Turner, an imago and 
some larval forms of Ledra aurita, Linn. 
Mr. G. C. Griffiths exhibited hybrids between Flatysamia 
cecropia (male) and P. gloveri (female), and between P. cecropia 
(male) and P. ceanothi (female) ; also between Actias luna 
(male) and A. selme (female). He read the following notes : — 
" The hybrids now exhibited were bred by Miss Emily L. 
Morton of New Windsor, New York ; the one between 
Flatysamia cecropia^ and P. gloveri, ?, in 1891, that 
between Actias luna, $ , and A, selene, ? , in 1892, and that 
between Flatysamia cecropia, $ , and P ceanothi, 9 , in 1893." 
In response to my request for information as to these 
interesting hybrids Miss Morton writes me as follows : — " As 
to the hybrids, to write their entire history would require 
more time than I could possibly spare at present ; in fact, our 
own Journals have asked me several times to send to them a 
history of the different kinds, but though I commenced a 
paper several years ago, I have up to date been unable to 
finish it. I can only reply to your questions as briefly as 
possible. The larvae take equally after both parents — the 
large size of cecropia, the bird's egg blue of gloveri intensified, 
with lemon-yellow tubercles, most beautiful objects. 
I do not know the larvae of ceanothi, the hybrid was not 
nearly as handsome a larva as the gloveri-cecropia, but was 
readily distinguished from any cecropia and grew to an
