Dr. CHAPMAN having been good sh to communicate to 
me, before publication, his admirable discovery of the early 
stage of Rhipiphorus paradoxus, I crave a few lines to con- 
qas him u a his success and to express the gratification 
which am sure, all other entomologists feel at the

insect 
as Dr. Chapman pointed out to me the key of
