Coquebert's figure of the femoral spot, exhibits its precise 

 form as in my insect. 



It appears to me, from the Fabrician character of L. gigas, 

 " aculeo longitudine abdominis" that Klug has misapplied 

 the specific name ; that his L. grandis, " aculeo abdominis 

 longitudine" is the Fabrician L. gigas, and that consequently 

 a different name ought to be given to his L. gigas.
