DYTISCIDiE. 
Experiments by D. Sharp upon the length of time spent submerged 
and on the surface '^or breathing exposure by various species of Dytis- 
cidm, reported in Nature, xv. p. 91 (published in extenso in P. L. S. 1877). 
Pelobius hermanni remains under water in a ratio of 375 to 1 of air 
exposure, and the more highly developed Dytiscus marginalis has a cor- 
responding ratio of 12 to 1. Pelobius, Hydrovatus, and Amphizoa are 
considered to represent the most rudimentary and primitive forms of 
existing Dytiscidce. 
Negative observations on the peculiar milky secretion of Dytiscides, 
from experiments on Dytiscus marginalis and dimidiatus, and Acilius 
sulcatiis and canaliculatus ; it is not injurious to other insects nor is it 
sexual ; it is a special fluid, not blood, secreted by cutaneous mono- 
cellular glands, and does not serve to form a greasy coating on the sur- 
face. F. Plateau, Ann. Eut. Belg. xix. pp. 1-10.
