Uggs. — I have not yet discovered the 
eggs of this insect, but the place where 
it deposits them is probably on the side 
of the apple, because the entrance of the 
larvae is easily recognized by a blackish 
spot at the side of the fruit after it has 
ripened; and it seems that usually only 
one egg is deposited on an apple. 
Larva. — At first whitish, with black head; when mature, it attains 
the length of half an inc^h, and takes on a fleshy color with many obscure, 
brownish spots on each segment, from which a single minute hair arises. 
Head, first and last segments, brownish in color. 
Larv;e live only in apple cores, injuring the seeds. 
The larva matures in a month, when it measures about 7™"^ in length. 
It makes a passage through the flesh of the fruit, and reaches the 
ground bj' letting itself down by a silken thread, or by crawling out 
soon after the fruit has fallen. In either case it makes a hole in the 
ground. 
1 An apple miner occurring in British Columbia has recently been reared by Dr. 
James Fletcher and determined by Lord Walsinghani as Argyresthia conjugella Zell. 
This species, of whi< h the writer has seen specimens through Dr. Fletchers courtesy, 
is so like Professor Matsumura's figure of the species under consideration as to sug- 
gest that they may be identical and that the Japanese insect has already been intro- 
duced into British Columbia. — L. O. H.
