This genus is unknown to me, but, judging from the description 

 and the figure of the wing, I believe it will be found to belong in 

 this group. Abbe Provancher originally described it as a Bracon 

 in the subfamily Aphidiince. but subsequently removed it to the 

 Helorincc in the family Proctotrypidce. 



The paper was briefly discussed by Messrs. Riley and 

 Howard.

THE DEATH'S-HEAD MOTH IN RELATION TO HONEY 

 BEES. 



By FRANK BENTON. 



Westwood states in vol. ii, p. 367, of his work on insects that 

 the Sphingid moth Acherontia atropos is the largest European 

 lepidopterous insect. It is not, however, confined to Europe 

 alone, but is found even more abundantly in North Africa and 

 Western Asia, my own experience with it having been mainly 

 acquired in Tunis, Syria, and Cyprus.
