Spraying for the Codling Moth.— Wo, wish to call l>iiiti(ulav attention to 

 tlir letter of Mr. John 8. Lnpton published in '' Kxtiaets from Cone- 

 spondenee," as affording- a. niarke<l illustration ol" the valne of sju'ayinf;^ 

 ai>ph' trees with the arsenieal mixtures for tlu^ Codlinj;- Moth. Few 

 l)rominent a])ple-gTowers at the present day in more northern and west- 

 ern States doubt the advisability of this reuuMly. Further south it has 

 not come so extensively into use. Mr. Lupton's experienet^ has made 

 him enthusiastieally in favor of the remedy, and no doubt will prove to 

 others Avho have been skeptical u]) to the present time that many hun- 

 dreds of dollars can be saved by careful au<l i>roper use of Loudon 

 purple or Paris green. 



'Mr. Craw on tne destructive Insects of California. — Mr. Alexander Craw, 

 Quarantine Officer and Entomologist of the California State Board of 

 Horticulture, has just published a little flfty page i)ami)hlet with the 

 title given in our footnote. He divides his matter into six heads, viz: 

 S(;ale-iusects, miscellaneous insects, beneficial insects, internal para- 

 sites, remedies, and spraying apparatus. The work ujiou scale-insects is 

 very well done, and includes a comi)ile(l account of twelve of the most 

 injurious scale-insects of California, Avith photogra|)hic reproductions of 

 several, and a very good colored plate of eight species. The lithograph- 

 ers have made the enlarged figure of the Red Scale too light colored, 

 aiul that of the San Jose Scale too bluish. 



Under the head of " Miscellaneous Insects " the Grape Leaf-beetle 

 {Acloxufi 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 SiphonopJiora reported as so abundant upon Hop is not 

 avence^ but one <if the other species of ^iphonophora 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 {Anisopteryjc po- 

 metar'm }iarnti=autiimn((ia 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. In the 

 same way the Forest Tent Caterpillar is mentioned as our old Clisio- 

 vampa sylrafica, whereas it is much more likely to be ('. mlifornica or 

 one of the undetermined species of this geiuis 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 

 si)raying 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

 Craw, Quarautine Officer aud Entomologist, Sacramento, 1891.
