344 SUPPLEMENT. 
Tuxtla is in very bad immature condition. The Bugaba specimen is therefore the only 
one which can be considered typical, and is the one figured. 
The following species or. doubtful varieties of Hydnocera it is well to notice; they 
are represented by single examples, and considering the caution that should be observed 
in- adding to so difficult a genus, I do not think any useful purpose can be gained by 
naming them, there being insufficient evidence that they are distinct.
