This beautiful variety was given me by my kind friend, Mr. Wil-

with two intermediate forms of the same variety.

ETHOLOGICAL NOTES ON ELAPHRUS CICATRICOSUS 
LEC. (COLEOPTERA) 
By C. A. Frost. 
A few words on the occurrence of this rare species of Carabide 
may enable some other collector to profit by my experience if they 
have plenty of time and patience. 
My first specimen was taken at Monmouth, Me., in 1907 (about 
June 20) on the shore of a lake near the mouth of a small brook. 
I was sifting a pile of washed-up debris for Staphylinidz when I 
noticed it running on the mud near where I had been standing. 
A careful search failed to discover any more at that time and each 
summer since, although I have even dammed up the brook in the 
hope of flooding out a specimen. The cause of its disappearance 
in this place is probably the removal of a heavy growth of alders 
that extended down to the edge of the water. 
On June 23, 1910, after working this locality in vain, it occurred 
to me to explore a cold swamp about a mile further up the lake. 
This swamp, which is never dry, is traversed by a clear trout brook 
fed by springs and it is so heavily wooded that the sunshine pene- 
trates into it hardly at all. In some places the mud is very deep 
and is covered more or less thickly with swamp grasses, dead 
limbs and logs. 
I began operations here with a rusty pint dipper which I picked 
up at the spring, and almost the first dipperful of water brought 
out a specimen of Elaphrus from a slight hollow near the brook. 
It was cicatricosus, and for an hour or more I worked the old 
dipper-until the bottom fell out—without success. I now think
