Concerns the manner in which the blood is forced into the caudal 
.appendages of larvae of various species ; the author argues that these tails 
have a respiratory function in addition to being organs of locomotion. 
Prosopistoma punctifrons. E. Joly announces the breeding of the 
perfect insect by Vayssi^re ; Bull. Soc. Ent. Fr. (5) x. p. Ixxv. McLachlan

might be a permanent larval form, and points out how the error probably

Long gelatinous egg-masses observed on stems of Potamogeton in a 
lake on the Catskills. During the night the masses apparently sank, and 
reappeared on the surface during the day, receiving the full rays of the 
sun. The larvae were hatched, but died in a few days ; they bore resem- 
blance to those of Diplax as figured by Packard.
