Spraying for the Codling Moth. We wish to call particular attention to 
the letter of Mr. John S. Lupton published in ‘Extracts from Corre- 
spondence,” as affording a marked illustration of the value of spraying 
apple trees with the arsenical mixtures for the Codling Moth. Few 
prominent apple-growers at the present day in more northern and west- 
ern States doubt the advisability of thisremedy. Further south it has 
not come so extensively into use. Mr. Lupton’s experience has made 
him enthusiastically in favor of the remedy, and no doubt will prove to 
others who have been skeptical up to the present time that many hun- 
dreds of dollars can be saved by careful and proper use of London 
purple or Paris green. 
_*Mr. Craw on the destructive Insects of California—Mr. Alexander Craw, 
Quarantine Officer and Entomologist of the California State Board of 
Horticulture, has just published a little fifty page pamphlet with the 
title given in our footnote. He divides his matter into six heads, viz: 
seale-insects, miscellaneous insects, beneficial insects, internal para- 
sites, remedies, and spraying apparatus. The work upon scale-insects is 
very well done, and includes a compiled account of twelve of the most 
injurious scale-insects of California, with photographic reproductions of 
several, and a very good colored plate of eight species. The lithograph- 
ers have made the enlarged figure of the Red Seale too light colored, 
and that of the San José Seale too bluish. 
Under the head of “ Miscellaneous Insects” the Grape Leaf-beetle 
(Adoxus vitis) is treated with a figure of its work and of the beetle it- 
self. The Hop Aphis and the Black Aphis of the Peach, Canker-worms 
and the Forest Tent Caterpillar are the other insects treated. We sus- 
pect that the Siphonophora reported as so abundant upon Hop is not 
avene, but one of the other species of Siphonophora which we have had 
from this plant. We are also, in the absence of definite information, 
inclined to doubt the finding of the Fall Canker-worm (Anisopteryx po- 
metaria Harris=autumnata Pack.) in California. The species which we 
have received from the Pacific coast is different and it is difficult to de- 
cide from the larva alone, which Mr. Craw has apparently done. Inthe 
same way the Forest Tent Caterpillar. is mentioned as our old Clisio- 
campa sylvatica, whereas it is much more likely to be C. californica or 
one of the undetermined species of this genus which we have received 
from California. Mr. Craw gives a very good summary of remedies and 
spraying apparatus and avoids the difficulty of recommending any one 
spraying machine to the detriment of others by giving a list of sixty-four 
dealers in the State of California alone. This well illustrates the spread 
of this new manufacturing industry. We may state in regard to the
