A New Species of Collembola From Laguna Beach GEETRUDE BACON In Vol. IV, No. 3, of the Journal of Entomology, I describedsome Collembola found at Laguna Beach of the genus the same summer, under the same conditions and en-vironment, I found a great number of specimens of the genusEntomohrya, which, due to the kindness of Professor L. , were identified as belonging to a new species. Thesewere found on the under side of large rocks as far out in thewater as it was possible to turn over the stones. This is the firsttime that this genus has been reported found under rocks in saltwater. This species occurred very abundantly, far more so thanany of the others, and was collected in great numbers.
