THE CANADIAN ENTOMOLOGIST. 



Itatiba, State of Sao Paulo, and I find they live in little crater-shaped 

 galls. The females have the antennje with 5 or 6 segments." It is quite 

 evident that the species which Prof. Cockerell examined was not C 

 Jabot icabce, but C. crateraformis. 



The species of Captilinia may be readily separated by the following 

 tabulated characters. Unfortunately, I have no material of C. Saiiei, and 

 the characters here given are taken from Sign, and Townsend A' 

 Cockerell.
