stroys the little character such delineation may possess. 
In the great variety we have examined, not even the rudiment 
of a tail ever appeared, and the only variation seemed to be in

ject so closely; it has been thought proper to retain it, that those 
who fall into the same opinion may bring the two Linncean in- 
sects together under a new name, in order to prevent further 
confusion, which might be the case were they joined under either 
of the original names.
