REMARKS.—It is a pleasure to name this species for Dr. Richard C. 
Froeschner, by whose kind offices I have had an opportunity to 
study this lot as well as many other Aradidae from the collections 
in his charge. 
Aneurus froeschnert, new species, is related to A. minutus Bergroth, 
1886, from which it differs as indicated in the key.

process conical, rounded anteriorly, reaching slightly beyond the 
tip of antennal segment I; jugae adherent to clypeus, not visible 
from above. Antenniferous tubercles short, truncate anteriorly, 
not acute. Eyes moderately large, protruding. Postocular tubercles
