 plant is, generally, a small oily-looking spot on an

 pull will bring away the central leaves.

 When it appears for the first time in a garden its 

 presence will probably not be suspected, by one having

 some plants have begun to turn yellow, and perhaps 

 not until they have been eaten to such an extent that 

 the whole sheaf has fallen to the ground. By this 

 time the larva is in the base of the sheaf or has just 

 entered the rhizome. It should at once be dug out —

 injured leaves should all be removed, and the chewed 

 portions of the rhizome scraped clean, and the leaves 

 and scrapings burned. All the other Iris plants should

Later, precautions should be taken to guard against 

 a new brood the following year in case any of the
