was on the pile of dirt outside the burrow, and the other specimens 

 were just inside the entrance. Movement of adults from one bm-- 

 row to another may possibly occur on warm cloudy days or late

0. polyphemi sparsiseiosus may be distinguished from other North 

 American species by the characters given under typical polyphemi. 

 It may be separated from typical polyphemi polyphemi by the greatly 

 reduced number of punctm'es, setae, and tubercles. The nearly 

 impunctate second elytra interval seems always to separate p. sparsise- 

 iosus from the more eastern p. polyphemi.
