INJURIOUS AND BENEFICIAL INSECTS. 535 
the earth from around the roots of those plants whose dark, shriv- 
elled leaves tell of the enemy’s presence. It is my belief that 
this devastation might have been spared by an outlay of from $20 
to $30 for labor, much of which, under proper direction, could 
have been done by children. Therein would have been saved a 
strawberry crop for the ensuing summer, worth scarcely less than 
$2,500, for from this same farm the crop of a single acre has been 
sold for $1,500. Then, however valuable such labors are in the 
immediate results, that is but a fraction of their worth as respects 
the future. These Cotalpa grubs, with all their mischief, had not 
more than a third of their ultimate size; hence their real ray- 
enousness is yet to come. Besides, what a prospect of increase of 
numbers, should even a moderate share of them reach maturity ! 
Why should not our farmers seek to know something about their 
insect-enemies, and when practicable put forth some energy to 
meet such ?” 
Snails Injurious to the Strawberry.— Under this caption Prof. 
E. T. Cox publishes in the Amertcan Narurauist (vol. ii, p. 
666) a note regarding the injury done in Indiana by a little snail 
(Pupila fallax), at present found occasionally though not abun- 
dantly in this state. Though this report refers chiefly to insects, 
yet in the future, as civilization advances and the country becomes 
more thickly settled, gardeners are undoubtedly destined to be 
plagued by these little animals, and a slight notice of them may 
not be out of place, as the ravages they commit may be some- 
times wrongly attributed to insects 
It seems that Mr. and Mrs. Chappalamite of New Harmony, 
Indiana, “found their strawberry plants dying rapidly, and on 
seeking for the cause discovered these mollusks at work upon the 
stems and crowns of the plants, rasping off the outer coating, and 
sucking their juices in such a manner as to cause them to decay. 
Mr. C. found as many as forty upon one plant, and thinks they 
have killed several thousand upon the different beds. Though 
more abundant on the strawberry, he has found them on a variety 
of plants. Since attention has been called to the depredations of 
these minute mollusks, they have been found at work upon the 
Strawberry plants in all the gardens examined.” 
Though this species is not common with us, yet we have other 
- kinds which are more or less so, and which may ultimately prove 
to be obnoxious. Yet it is not probable that snails will ever be
