50 Trans. Acad, of St. Louis 



Saprvnus lungens Erickson. [E. A. Schwarz]. 



Saprinits assimUis Payk. [E. A. Schwarz.] Shaken 

 out of head of dead robin, in company with several other 

 beetles, in May 1916. 



Chalcolepidius viridipilis Say. [E. A. Schwarz]. 



Alaus oculatus Lem. [E. A. Schwarz]. These two 

 chick-beetles were taken at St. Louis the first of July, 

 1915. 



Limonius agonus Say. [E. A, Schwarz]. Found on top

 on June 6, 1915.

Lucanus dama Thunb. This stag-beetle was taken at 

 Moselle, Mo., the female under rotten bark, on July 1, 

 and the male on the wing at the lights on July 2. Later, 

 in confinement, they ate of grape leaves and strawberry. 



Passalus cornutus Fab. Three of these, kept in con- 

 finement and fed on disintegrating white oak wood, lived 

 from March 1 to June 4. Three others taken on April 

 7 died the middle of August. 



Canthon chalcites Hald. [E. A. Schwarz]. Thou- 

 sands of these dung-rollers were seen about Wesco about 

 August 1, busying themselves in every available variety 

 of dung, crowding each other for choice bits and trun-
