THE CANADIAN ENTOMOLOGIST 



The writer succeeded in obtaining eggs from reared parents 

 which mated in the rearing cages, and from these larvae were 

 obtained and successfully brought to maturity. More than 100 

 adults in all were reared. 



In addition to careful observations on the behaviour in copu- 

 lation, mechanism of oviposition, duration of immature stages, 

 larval habits, etc., detailed descriptions are given of the larva 

 and pupa, containing valuable information on the minute struc- 

 tures of the larval mouth capsule and other structural features. 

 The figures illustrating these features are the work of the author 



and are admirable.
