 {Prunus integrifolia) at Sierra Madre in Los Angeles County, Cal., was found 

 to be badly infested with the larvce of Mellissopus latiferreana, a moth which 

 closely resembles the coaling moth. " The infestation was very heavy. The 

 larva works both in the meat of the fruit and within the seed itself, which is

 The cherry averages about the size of the cultivated species of cherry. 

 The larva seems to have a preference for the seed, the shell of which is not 

 very hard."
