Alfred Giard, Charge d’Cours in connection with the Faculty of 
Science at the Sorbonne, to whom I am indebted for much of 
the information contained in this paper, about the same time 
experimented with entomogenous fungi, belonging to the class 
Entomopthora, but was not, however, able to cultivate them 
■artificially apart from the insects on which they were naturally 
met with, or to which they had been communicated. He wa.s, 
however, subsequently successful with Isaria densa, which lives 
on the rrr ldanr, another destructive scarabmid larva ; and this 
ungus which was thus found to be capable of being artificially 
ultivated, was also discovered to be available for the direct
