The Elm-leaf Beetle. 



Galeruca xanthomelcena came in great force in June, and defoliated 

 all our beautiful elms, to the great injury of our village. In the third 

 week of July the trees all put forth a new crop of leaves, about one- 

 third the size of the iirst crop. In the fourth week of July the second 

 brood of Galeruca came, and devoured the new leaves. We are all 

 auxious to see whether the trees will stand this treatment next spring. 

 I fear our line elms here are all doomed. — [Rev. Samuel Lockwood, 

 Freehold, N. J., August 6, 1S83. 



Grape Pest— Codling Moth. 



I send you to-day a beetle which you will confer a favor by determin- 

 ing at your earliest convenience. You will remember I sent you a 

 Blapstinus said to be destroying foliage of grape-vines. Now here is 

 another Tenebrionid that in one case has destroyed 35 acres of grape-vine. 

 (Further particulars soon.) I also send you a codling moth I raised from a 

 pear four years ago. I found quite a number last year. Is this a differ- 

 ent species from Garpocapsa pomonella, or only a variety? The speci- 

 men is in vial. — [Matthew Cooke, Sacramento, Cal, July 23, 1883. 



[The Tenebrionid sent was Eleodes quadricollis Lee; a very numerous 

 species in the more northern part of California. The species of that genus, 

 so numerous and abundant in the region west of the Rocky Mountains, are 

 all known to feed upon decaying vegetable matter, and none have hith- 

 erto been reported as doing damage to cultivated^ plants. In fact, this 

 communication, if correct, would indicate a change of habit hitherto un- 

 precedented in the history of economic entomology, and, unless further 

 proof be brought forth, we can hardly believe that the species referred to 

 is the real author of the damage to grape-vines. The only species of the 

 large family Tenebrionldce which can be considered as injurious are 

 those feeding on stored produce, e. #., Tenebrio molitor, T. obscurus, Tri- 

 bolium ferrugineum, Gnathocerus comutus, and a few others. 



The codling moth was an interesting variety of Garpocapsa pomonella y 

 with obsolete maculation.l 



The Wheat Midge. 



I find that I have fallen into the error of using a name for the wheat 

 pest that is in erroneous use here (weevil). The one I mean is called in 

 Ontario the midge. It comes out in the fly state in July, and deposits 

 its eggs near the kernels when the wheat is in its early stage. The yel- 

 low grubs live upon the wheat in its milky state and leave it shriveled 

 and worthless. When we get a very early season, as this is, the wheat
