The series of specimens here recorded illustrates an East African 

 form, named A. variegatum by Kirby and Sjiistedt (specimens from 

 Nyasalaud and from Kiliniandjaro respectively), the writer's form B 

 of the subspecies. Its distinctive features are — comparatively large 

 size, dilatation of fifth abdominal segment verv slight.
