The Elm-Leaf Beetle. (Country Gentleman, for October 15, 1885, L, 

 p. 841, e. 3-1:— 23 cm.) 



The inquirer, from Bordentown, N. J., of methods for killing the insects 

 destroying the foliage of his elm trees, is referred to a notice of this insect, 

 Qaleruca xantJiomelana, in the Country Gentleman for Oct. 12, 1882 (p. 805), 

 and to Bulletin No. 6 of the Division of Entomology of the U. S. Agricultural 

 Department. Of the arsenical insecticides recommended, London purple is 

 preferred, in the proportion of one-half pound to three quarts of flour and a 

 barrel (40 gals.) of water. Directions are given how to mix the preparation, and 

 the advantages of its use are stated. 



The Clubbed Tortoise Beetle. (Country Gentleman, for October 15, 

 1885, L, p. 841, c. 4—12 cm.) 



Remarks upon Coptocycla davata (Fabr.), its appearance, habits and food- 

 plants. Reference to its occurrence upon the potato, tomato and egg-plant. 



A Leaf-mining Insect. (Home Farm [Augusta, Me.] for October 

 15, 1885, p. 1, c. 6—20 cm.) 



A leaf-miner, reported in Maine, and in the vicinity of Boston, Mass., is iden- 

 tified as one of the Anthomyians, and probably Chortophila betarum Lintn., 

 which has distribution in New York and Connecticut. The approved methods 

 for meeting its attack, are prevention of egg-deposit by the use of counter- 

 odorants, and burning the infested leaves. 



The Death- Watch, Clothilla pulsatoria. (Country Gentleman, for 

 October 22, 1885, L, p. 861, c. 3-4—21 cm.) 



A supposed parasite found in cow-stalls in Warren, 0., is this insect, a figure 

 of which is given. The habits of the Psocidae are briefly stated, and the reason 

 why this species has received the name of the "death-watch." It has pre- 

 viously occurred in immense numbers, in barn refuse after threshings, and in 

 straw-packings in a wine cellar. 



Eggs of a Katydid. (Country Gentleman, for October 29, 1885, p. 

 881, c. 4—23 cm.) 



Eggs sent from Lexington, Ya., arranged in two rows upon the opposite side 

 of the back fold of a copy of the Country Gentleman, are those of Mierocentrus 

 retinervns, an insect common in some of the warmer States of the Union, and 

 classed by some writers with the katydids, although strictly, the name of katy- 

 did would belong only to Platyphylluni concavum. The eggs are described, 

 and reference made for the illustration and life-history of the species to the 

 6th Missouri Report. 



A New Insect Foe to the Cut-worm. (Xew England iIomestead> 

 for October 31, 1885, xix, No. 44, p. 405, c. 3-4—19 cm.) 



A correspondent from Winsted, Ct., sends for information a fly hatched from 

 some cabbage cut-worms kept in confinement. The fly is a species of Gonia 

 belonging to the Tachinidce, the parasitic habits of which are given. Caterpil- 

 lars bearing upon their body the white eggs or the egg-shell of these flies 

 should not be destroyed, but permitted to furnish food for the beneficial larvae 

 that are feeding within them. The cabbage cut- worm was probably Mamestra 

 trifolii.
