cn feet six inches across the wings, 
from tip to tip, (not 8 ft. 6 inches, as 
a Pueblo paper had it,) 
We shall be very glad of informa- 
tion as to the distribution of the 
mountain lion (Felis coftcolor) in 
Colorado. At present we have re- 
ceived reports of it from only nine 
counties, namely Delta, La Plata, 
Routt, Pueblo, Cutter, Fremont,' 
Gunnison, Eagle and Summit. 
In 1887 we found a curious yellow 
fungus growing on a dead tree at 
Wellsville, in Fremont county, and 
afterwards sent specimens to Dr. W. 
G. Farlow, who wrote concerning it: 
“The only name I can now give to it 
is Corticium setosum, Berk. & Curt. 
That is the name given to it in the 
authentic collection of Curtis, al- 
though I believe the description was 
never published. As a matter of fact 
the fungus is not really a Corticium, 
but it seems to me.'rather an imperfect 
fungus, and I am inclined to regard 
it as a degenerate condition possibly 
of some Myxomycete.” The only 
genuine Corticium we have so far met 
with in Colorado, is one on Quaking 
Asp bark in western Custer county, 
which Mr. I. B. Ellis says is piobably 
O. populinum. 
Early in April last year, while walk- 
ing near Swift creek, we came across 
a specimen of the common round cac- 
tus (Cereus viridiflorus) which appear- 
ed dead or dying, and on removing 
it from the ground we found it quite 
hollow, and tenanted by a large bee- 
tle-larva, pale yellowish in color, with 
curiously bifid dorsal tubercles. We 
sent this destroyer of cacti alive to 
Dr. Riley, who replied that it was an 
extremely good specimen, and evi- 
dently the larva of Cactophagus vali- 
dus. 
On the 8th of last March we found 
a large cocoon, about two inches long, 
on a Bigelovia plant near Ula. It was 
silky grey, exactly the color of the 
Bigelovia stalks, and* so hard to dis- 
tinguish, notwithstanding its size, that 
we did not know what it was until we 
had it in our hand. On the 18th of 
June, a grand moth emerged from 
this cocoon. Its name is Sarnia glo- 
veri. In Utah, where it is quite com- 
mon, the caterpillar feeds on currant 
and gooseberry, but there were none 
of these near where we got our cocoon, 
nor have we been able to find any co- 
coons on currant or gooseberry bushes 
here. 
About the middle of April last year 
the butterflies began to fly in western 
Custer county. One we caught 
proved to be Pieris sisymbri, a butter- 
fly which has generally been regarded 
as belonging only to the Facific slope. 
Mr. W. S. Foster, writing from Sa- 
lida, says that P. sisymbri is also com* 
mo'n in his locality in the early spring. 
Mr. H, W. Nash writes us that a 
pigmy owl (Glaucidium passerin/um 
californicum) was killed near Pueblo 
recently. 
In 1887 we found two butterflies in 
northern Summit county, which were 
27
