19.Q [June 



This species belongs to this Section, and was accidentally omitted 

 in the Table given on page 135 ; the scutellum and last abdominal seg- 

 ment differs in color from that stated in the Table, which should there- 

 fore be amended to read as follows : — 



Section 9.— Scutellum yellow or red ; abdomen red or red and black, 



apex white or yellow Sp. 74 — 76 



Genus ISCHNUS, Grav. 

 Under this genus, I have placed those species which only differ from 

 Ichneumon, in the basal segment of the abdomen being smooth and 

 polished, while those of the latter genus have that segment more or 

 less ru2:2red.
