skin the larva as it grows may excavate cavities or holes extending 
into the flesh from one-fourth to one-half inch, or deeper. This sur- 
face injury, which may occur on the ends or sides, while perhaps not 
more serious in its effect than the borings at the calyx and stem ends, 
is more conspicuous and greatly disfigures the fruit. (See figs. 1 and 
= ri. VEL.) 
Larve of this species apparently do not reach full development as 
early in the fall as those of the codling moth, and many find their 
way into the barrels, where they continue to feed, in some instances 
observed doing considerable damage, the introduction of the infested 
fruit being favored by the inconspicuous nature of the injury when 
occurring in the ends of the apples. 
DESCRIPTION. 
Egg.—tThe egg stage has not been observed. 
Larva.—Full-grown larve (at time of leaving fruit in fall for
