A PSEUDOSCORPION FROM GUATEMALA. 
E. W. Berger, Ph. D. 
This Pseudoscorpion was collected by Professor James S. 
Hine just to the west of Gualan, Guatemala, January 15, 1905. 
The writer has identified the same as Atemniis elongatus, Bks. 
Mr. Banks sums up its (I, 1895) occurrence in the following 
lines; “Beaten from dead hickory wood in April near St. Lucie 
Riv., Indian River, Florida, by Mr. Hubbard; also at Sand 
Point and Enterprise, Fla., Punta Gorda, Fla., (Mrs. Slosson). 
A young specimen taken by myself at Runnemede, Fla., may 
belong to this species;” etc. To this should, of course, now be 
added Gualan, Guatemala. The chief interest to me of this find 
is, that it is another instance illustrating the extended north and 
south distribution of certain species of the Pseudoscorpionidae. 
In a previous paper (II) I made note of the fact that many 
species have a far north and south distribution, but not a very 
extensive one east and west. Thus none of the native eastern 
species were found to occur upon the Pacific Coast, and vice 
versa, while several of the species in the Eastern States are 
reported from Jamaica (II) to New York, and no doubt will be 
found farther north. For illustration I mention Chelanops 
oblongus. Say, and Chthonius pennsylvanicus, Hagen, each of 
which have the distribution mentioned. 
The Atemnus elongatus was found to the east of the highlands 
of Guatemala, but whether it occurs to the west of these Pro- 
fessor Hine did not determine. 
The specimens were collected from under the dead bark of an 
inclined tree, the under half of which was still alive. The 
animals were found in groups of a dozen, more or less, and 
ajjparently very much involved in some threads of silk, pre- 
sumably of their spinning. This was also the condition of the 
|)reserved specimens. I was surprised at the manner in which 
these were tangled up into a bunch with threads of silk, until 
Professor Hine explained to me the condition in which he had 
found them. The significance of this condition I do not under- 
stand. It occurs to me that they may have been in some con- 
dition of rest for the season, which is dry at that period of the 
year. The animals, however, were not torpid and scattered 
when disturbed and this manner of congregating in groups may 
be nothing more than a regular habit. The fact, however, that 
several other species of larger arthropods were observed con- 
gregated into groups, literally by the hundred, seemingly in 
some condition of rest approximating hibernation, makes the 
belief, that the pseudoscorpions were in a similar condition, not
