Gall-Producing Insects.—Mr. Wm. Beutenmiiller, of the Amer- — 
ican Museum of Natural History, publishes’ a useful Catalogue of © : 
Gall-producing Insects found within fifty miles of New York City 
Eighty-eight species are enumerated, the family distribution of which — 
is: Cynipide, 40; Tenthredinide, 2; Cecidomyide, 32; Tripetide, 2; 
Psyllidæ, 5; Aphidide, 6; Acaroidea,1. The next to the last family — 
is called Aphide instead of the more correct Aphidide. “The vege — 
table deformations called galls,” writes Mr. Beutenmiiller, are pro- — 
duced by insects. Generally an egg is inserted in a bud, a leaf, a root, — 
or some other part of the plant, and the presence of this foreign body — 
among the vegetable cells causes an abnormal growth of a definite — 
shape. The variety of galls in respect to texture and substance is very — 
great. Every species of gall-producing insects attacks its own partic: 
ular plant, and a particular part of that plant, and produces a gall of | 
a definite and uniform structure.” The two plates accompanying (due 
to the courtesy of the author) show a variety of common galls. Plate 
(IIL) represents those made by the minute two-winged flies of the genus 
Cadomyia ; and (IV) those made by the four-winged flies of the family 
Cynipidæ. 
Recent "Publications.—Mr. Henry G. Hubbard publishes’ an 
extended description of thelarva of Amphizoa lecontei, illustrated by 
an admirable plate. He extends Schiödte’s table of the larval charac- 
ters of the principal families of adephagous coleoptera. : 
Through the cooperation of the Massachusetts Society for Promoting 
Agriculture, the Hatch Experiment Station of the Agricultural Col- 
lege has issued an edition of 45,000 copies of a bulletin concerning 
canker-worms, tent caterpillars, fall web-worms and tussock moths
