THE DIODONTI. 107 



young of 0. corruscans, disappeared two days later without 

 having exerted any evil influence upon the destiny of the right- 

 ful owner of the nest. 



Diodontus gracilis and corniger are said to provide aphides 

 for their young, making their nests in holes in posts, while 

 minutus and tristis, like americanus, burrow in tie ground. 

 Americanus seems to be the only American species of which 

 anything is known.
