Twelfth Eeport of the State Entomologist 355 



The Beech-Tree Blight. (Country Gentleman, for September lo, 1896 

 Ixi, p. 705, c. 4 — 26 cm.) 



Beech leaves from Scarsdale, N. Y., are thickly infested with 

 Schizoneura ivibricator (Fitch). The enveloping white substance is 

 noticed, and the honey dew which it secretes. As the insect is 

 difficult to reach with insecticides, crushing the collected masses 

 is recommended. 



.Elm-Tree Borer. (Country Gentleman, for September 24, 1896, Ixi, p. 

 746, c. I — 14 cm.) 



A borer, infesting elm-trees in Peoria, 111., is identified from the 

 account given of it, as the elm-tree borer, Saperda trideiitata Olivier. 

 The best remedies for it are these : i . Removing the dead bark over the 

 infested portion until the insects are reached, and applying kerosene 

 emulsion to kill them. 2. Preventing egg-laying by coating the 

 portion of the trunk threatened with a repellant coating in which Paris 

 green and carbolic acid are mixed.

The Cecropia Moth. (Country Gentleman, for September 24, 1896, 

 Ixi, p. 746, c. 2 — 9 cm.) 



A supposed vegetable growth on a grapevine, from Auburn, N. Y., 

 is the cocoon o{ Atiaciis Cecropia. Features of the cocoon are given 

 from which it may be recognized. 



Imported Scale Insects. (Country Gentleman, for September 24, 1896, 

 Ixi, p. 746, c. 3 — 13 cm.) 



In commenting on a statement of the recent arrival at Seattle, 

 Wash., of a steamship from Japan, with some Japanese plants badly 

 infested with a destructive scale-insect, the importance is urged of such 

 quarantine regulations at that port as shall prevent the introduction of 

 the scale insects of Japan, and also at other of our ports where plants 

 and fruits are largely imported. The particular scale referred to 

 above, Diaspis lanatus, has been in the United States for at least four 

 years, having probably been introduced from the West Indian Islands, 

 and is now in Florida, Georgia, and District of Columbia on peach 

 trees. How destructive it may prove, remains to be seen. 



Pea Bugs. (Country Gentleman, for October 1, 1896. Isi, p. 763, cols. 



3, 4 — 12 cm.) 



In reply to inquiry from Baiting Hollow, L. I., the life-history of 

 the pea-weevil, Bruchus pisonim is given, and for killing the insect, 

 chloroform or bisulphide of carbon are recommended. 



Rose-Leaf Hopper. (Country Gentleman, for October i, 1896, Ixi, p. 



763, c. 4--10 cm.) 



A remedy is asked for from Port Kent, N. Y., for " a small white fly 

 infesting rose-bushes." It is i)robably "the rose-leaf hopper," Typhlo-
