I had three specimens, all females. 



3. Polydesmus canadensis Newport. 



This species was most abundant in the neighborhood of Titi swamps. 

 All the specimens found were very dark chestnut or black. They are 

 also notably diiierent from the species found in Indiana in form and 

 size, being uniformly smaller, with the ends of the body tapering more 

 gradually, but they agree well in the form of the genitalia. 



4. Lisiopetalum eudasum McNeill. 



A few specimens of this species, which has hitherto only been reported 

 from Indiana, were found. The specimens found agree well with the 

 published descriptions.

This species was found abundant. The specimens do not differ ma- 

 terially from individuals of the same species in the Central States.
