logy by a probable majority, may be in- 
duced to turn their attention to the anat- 
omy, biology or physiology of American 
insects. The study of the general anat- 
omy of insects can be pursued in any 
country, but there always remain special 
points in the anatomy of insects, of which 
points glands and similar modifications 
of parts of insects for special purposes 
‘orm no small part, wherein insects of 
one country differ from those of any 
other. In such fields of study as these 
young American entomologists can com- 
pete most successfully with European 
anatomists and can make important dis- 
coveries, and to researches of this kind 
future entomologists who have aspira- 
tions to become more than locally known 
must turn their attention. Leave the 
creation of scientific names, quarrelling 
over syhonyms among them, and search 
for new spe ies, to the antiquated type 
of naturalists who have become so ha- 
bituated to studying the exterior of their 
insects that to ‘‘destroy” a rare speci- 
men by dissecting it has become a crime 
to them. In their regard for the exte- 
rior of animals, coupled with their crude 
knowledge of internal anatumy, they re- 
mind me of Romans, who makes a grave 
statement in his history of Florida (p. 
55), that ‘‘Anatomy has taught us, that 
the bone of a negroe’s skull, is always 
black.”
