A New Species of Collembola From 
Laguna Beach 
GERTRUDE BACON 
In Vol. IV, No. 3, of the Journal of Entomology, I described 
some Collembola found at Laguna Beach of the genus Jsotoma. 
During the same summer, under the same conditions and en- 
vironment, I found a great number of specimens of the genus 
Entomobrya, which, due to the kindness of Professor L. W. 
Folsom, were identified as belonging to a new species. These 
were found on the under side of large rocks as far out in the 
water as it was possible to turn over the stones. This is the first 
time that this genus has been reported found under rocks in salt 
water. This species occurred very abundantly, far more so than 
any of the others, and was collected in great numbers. This 
paper is a study of the characteristics of this species.
