BY A. N. CAUDELL. Washington, D. C. 



In the collection of insects made in Mexico some years ago 

 by Dr. E. Palmer, was a single specimen of a new species of 

 walking stick, with short antennae, belonging to the genus 

 Bacillus as used by Scudder for the United States species.* 

 This insect may be called Bacillus pctlinrri and described as
