XI. A Shetch of our present knowledge of the Neuropte- 
rous Fauna of Japan (excluding Odonata and 
Trichoptera). By R. M‘Lacuuay, F.L.S., &e. 
[Read 7th June, 1875. ] 
As a continuation of the numerous memous on the 
Entomology of Japan that have appeared in our Trans- 
actions during the two preceding, and present, years, I 
offer a short sketch of our knowledge of a portion of the 
Neuropterous Fauna of the islands. The dragon-flies 
( Odonata) are omitted, because in them no materials have 
come before me; and I think that my friend Baron De 
Selys-Longchamps has the idea of publishing an account 
of those that are known to him at no distant date. The 
Trichoptera are not at present included, because, owing 
to pressure of other work, I have not been able to find 
time to make the drawings so indispensable when treating 
upon them; it must suffice to say here that the group is 
numerously represented in Japan, and contains many ex- 
traordinary forms. Limiting myself, therefore, to the 
Pseudo-Neuroptera (excluding Odonata) and Planipennia, 
I can enumerate only about 45 species, and of these some 
are not described for want of sufficient material. 
It is to the collections made by Mr. H. Pryer, of Yoko- 
hama, and sent by him to his relative, Mr. Wormald, that 
I am indebted for an opportunity of studying the greater 
part of the insects here noticed. From Mr. George Lewis 
I have received several interesting species. In addition 
to these, some species exist in the collection of Baron De 
Selys-Longchamps (to whom I am indebted for dupli- 
cates), in that of the British Museum, and in my own. 
Lastly, and by no means of the least importance, Mr. 
Ritsema, of the Royal Museum of Natural History at 
Leyden, has entrusted to me a small collection, chiefly 
formed by Von Siebold the well-known traveller in Japan. 
Instigated by a knowledge of the exclusive privilege of 
trading with Japan so long possessed by Holland, it oc- 
curred to me to apply to Mr. Ritsema, and the result is 
that he forwarded to me several forms of the highest inte- 
rest, and which have not been found by subsequent ex- 
plorers.
