A STUDY IN HYPERPARASITISM 5 
Although frequently reared from cocoons of A. melanoscelus, H. ful- 
vupes is by no means so important an enemy of this Apanteles as H. 
tenellus. In the foregoing list it has been included among the 14 
hyperparasites which are most abundantly reared from that species, 
but it falls well down in the list. 
HEMITELES APANTELIS CUSHMAN (5) 
Hemiteles apantelis was only rarely encountered as a parasite of 
Apanteles melanoscelus; according to the observations of the writers, 
at least, it is at present of no importance as an enemy of this primary. 
It is included here, however, in order to record its occasional occur- 
rence in this role. It is possible that under certain conditions it may

become much more destructive. There is usually but a single genera- 
tion annually, which hibernates in the form of full-grown larvae. Co- 
coons attacked as early as May 20 to June 15 did not produce adults 
of the hyperparasite until May of the following year. In partheno- 
genetic reproduction males are produced. 
ACROLYTA EMPRETIAE ASHMEAD 
Only a few specimens of Acrolyta empretiae have been obtained 
from cocoons of Apanteles melanoscelus. In biology it exactly re- 
sembles Hemiteles fuluipes. Adults appear in May and attack the 
cocoons of various species of Apanteles. There are several genera- 
tions annually, development from egg to adult requiring only from 
16 to 20 days. Like all the species of Hemiteles, it is a solitary par- 
asite, and passes the winter as a mature larva within the host cocoon. 
The progeny of unfertilized females are males.
