PUBLICATIONS OF THE ENTOMOLOGIST. 



The following is a list of the principal publications of the Entomologist 

 during the year of 1895 : 50 are named, giving title, place and time of 

 publication, and a summary of contents. 



Ants in a Lawn. (Country Gentleman, for January 3, 1895, Ix, p. 9, cols. 

 I, 2 — 34 cm.) 



A remedy requested for an infestation of ants in a lawn which was 

 formerly dense woods, at East Williston, N. Y., can not be given with- 

 out a knowledge of the species. If the yellow ant, Formica rufa, it 

 m;iy be destroyed in its mound by introducing bisulphide of carbon. 

 If the ants can not be traced to their mounds or nests, then, at a time 

 when the lawn "is alive" with them, they may be killed with kerosene 

 emulsion. Lime or kainit, used as directed, may also prove effective 

 against them.

The Apple-Tree Aphis. (Country Gentleman, for January 10, 1895, Ix, 

 p. 27, cols. I, 2 — 40 cm.) 



For an unusually severe attack of aphis in an orchard at George's 

 Harbor, British Columbia, kerosene and lime applied to the trunks of 

 the trees had been recommended. This would not be effective, and 

 why not. The proper remedy is spraying with kerosene emulsion as 

 the young are hatching. 



Can the blackening of the trunks and branches and stickiness of the 

 leaves result from Psylla attack on pear trees ? It is unusual with 

 aphis but common vvith Psylla. But the Psylla has not been reported 

 from British Columbia, while the apple-tree aphis was quite destructive 

 there (as quoted) in 1893, and its eggs have been received, fairly black- 

 ening apple twigs from Oregon. Reply to question — the Boideaux 

 mixture may follow the application of kerosene, or be combined with 

 the emulsion. 



The Apple-Tree Bark-Louse. (Country Gentleman, for January 10, 

 1895, Ix, p. 27, cols. 2, 3 — 45 cm.) 



In answer to inquiries with specimens from Pleasant Plains, N. Y., 

 the above-named insect, Mytilaspis pomorum, is identified. Instead of 

 cutting down badly infested trees, as in years ago, we can now kill the 

 insect and save the trees. The young can be killed by kerosene 

 emulsion spraying at the proper time. Few persons seem willing to 

 devote the time to fight insect pests, yet the future of fruit-growing 

 depends upon its being done. The winter months are favorable for
