leaves, the larva making its way thence to the nearl^y fruits, which it 

 enters. The principal work is around the core of the pear. The 

 larval stage lasts three weeks or more, and the pupal stage is passed 

 within the fruit. The insect hibernates in the ^g^ stage. The moth, 

 larva, and pupa are illustrated 

 by tig. 4. 



ZTnl'mnnn. caterpillar worhing

 Opportunity is taken of pre- 

 senting the reproduction of a 

 photograph of apples injured 

 by an insect, which in its larval 

 stage somewhat resembles the 

 codling moth, but which we 

 have as yet failed to rear and 

 identify. 



The injury was first brought 

 to the attention of the Division 

 of Entomology l)y Mr. D. W. 

 Coquillett in October, 1901. 

 The apples furnished were pur- 

 chased in open market in the 

 city of Washington. The in- 

 jury appeared to be almost ex- 

 clusively on the outer surface, 

 consisting in the cutting away 

 of the skin and disfigurement 

 of the apples and considerably 



depreciating their value as salable articles (see PI. II, fig. 2). In 

 some cases holes entering the fruit to the depth of about one-fourth of 

 an inch were found; in one apple to the depth of one-half inch. In 

 November Dr. L. O. Howard also furnished specimens of apples 

 showing injury by the same species. One of the larva^ spun up and 

 formed a cocoon Noveml)er 6. Unfortunately all the larvi^ died with- 

 out our securing the moths. The following lirief description of the 

 larva was made: 



Reddisli flcsli-colored, head dark l)ro\vii, central portion of face whitisli and trans- 

 parent, with two black spots; cervical sliield transi)arent, except for caudal margin 

 Three seta' on the pre-spiracular tubercle. Length, five-eighths of an inch when 

 spinning cocoon. 



It will be noted that the injury illustrated and descril>ed is quite 

 difterent from that mentioned and figured on pages ST and 88 of Bul- 

 letin "No. 10 (new series) of the Division of Entomology.
