Pratt replied that he had seen specimens from California and 
there was no reason why other species should not exist on the 
coast further north. Dr. Hopkins stated that he had had 
some experience in West Virginia and Maine with these insects 
and they were exceedingly troublesome. 
Dr. Hopkins exhibited specimens of fossil mesquite wood 
from Texas Hill, Arizona, showing distinct fossilized borings, 
apparently of a Cerambycid larva; and some fragments of 
petrified wood from the same locality showing insect borings 
filled with perfectly preserved egg-like objects. 
Dr. Hopkins made a few remarks on the Scolytid larvae 
and their mouth-parts. He stated that he had found very 
constant characters in the larva which greatly simplified the 
classification of several groups. A box of pinned larvae was 
exhibited, and several plates of drawings were also shown. 
Dr. Gill asked if the larval hooks mentioned by Dr. Hopkins 
were co-ordinate with any character in the adult. Dr. Hop- 
kins replied th^t so far as he could determine they were not. 
Mr. Banks presented the following paper: 
NEW TRICHOPTERA FROM JAPAN. 
BY NATHAN BANKS. 
Some time ago Mr. S. I. Kuwana sent me a small collection 
of caddice-flies from Japan. I was at work on them when Mr. 
Nawa reached Washington bringing some more species. The 
following paper is based on these two collections. They con- 
tain 25 species, 9 of which have been described, 12 of which 
I describe herewith, and four are represented by females not 
sufficiently characteristic to be described. Two of the described 
species have only just been published by Dr. Ulmer, and I had 
them in manuscript. Three new genera are described, all in 
the L/imnephilidae. None of the species are European, but one 
was described from Eastern Siberia. Doubtless collections 
from the northern parts of Japan will show some European 
species. * 
Too few species are as yet known to make any generaliza- 
tions regarding the trichopterous fauna of Japan. There are 
several remarkable genera present, most noteworthy is Peris- 
soneura which has a series of costal cross veins. It may be 
also mentioned that the largest caddice-fly known is from 
Japan, Holostomis regina, a magnificent insect.
