name. We can not introduce a new name in most cases des- 
pite our most serious efforts. For over a century a little 
gray neighbor of man had borne the dignified name of body 
louse, then the war threw us into the trenches and zowie! 
We came out with cooties! It is unfortunate that the econo- 
mic entomologists did not have foresight enough to intro- 
duce all of our unnamed pests into “the big parade” so that 
each would have come out wearing an A. E. F. name as 
firmly fixed for distinguished service as cootie. 
GEOTRUPES HORN I BLANCHARD 
This is one of the common species of the genus in this 
locality occurring, according to my series, from August 8 to 
September 30. It can be easily distinguished from the other 
species by its pure black color with no metallic reflections. 
I have found it frequently under a fungus having an acrid 
milky juice (Lactarius, perhaps piperatus) and it often 
bores from the top down through the stem and into the 
ground to a depth of five or six inches ; I have never noticed 
this particular mode of attack by G. balyi Jek. which at 
times frequents the same species of fungus. I have found an 
adult, a pupa and a larva beneath the same fungus though it 
is not certain they were all horni. Generally but one or two 
specimens are taken under one plant while balyi may occur 
in from two to six specimens. Horni occurs in rather dense 
growths of oak and I took several specimens in a pine grove 
at South Paris, Me., on September 20, 1928. It was taken at 
Monmouth, Me., on September 4 and 9, 1917, under fungi. 
A dead specimen was picked up on the sand area back of the 
beach at Surfside on Nantucket Island on September 13, 
1928. The range of this species is much greater than form- 
erly recorded as I have a specimen taken by Dr. T. H. Frison 
at Urbana, Illinois, bearing the unusual date of April 16, 
(1914).
