The insects included in this subdivison, differ 

 principally from those of the preceding in the form 

 of their abdomen ; which, instead of being conical 

 and very acute, is cylindrical and obtuse : the claws 

 also in the aculeate sex are bifid. Whether the 

 anus of the males is armed with spines or not I 

 cannot tell, having never taken an individual of 

 that sex belonging to this subdivision ; and of the 

 other sex I have only met with three specimens. 

 I had originally included the two species that I 

 possess in the last subdivision of my second sec- 

 tion of this family, mistaking them for male insects ; 

 but when I found that they were females, that 

 their exterior palpi consisted only of two joints, 

 and that the under side of their abdomen was 

 v/ithout hair, I was under the necessity of forming
