PASSALUS, 
P. cornutus Fab. 
L. elaphius is rare here, the others common. While in the British 
Museum some years ago, a specialist, who was working on the 
LUCANID/, expressed a wish for some fresh Passalus, for dis- 
section. On my return to Ohio, I sent some in a small box by mail. 
About a month after my box, like the proverbial cat in the song, 
“came back,’ and stamped on it in red letters, were these words: 
“Suspected to be potato beetles, not allowed entry.” The speci- 
mens had been examined very carefully, and after due deliberation, 
they decided that a dead Passalus cornutus was a living “potato 
beetle”!
