The number of eggs laid at one time variesfrom two to thirty, and each female (Fig. 161, -?,) depositsabout two hundred eggs. As soon as hatched, the younggrasshoppers (Fig. 186, lb, lb,) begin to feed upon the pulpypart of the leaf. They do not pass through a quiet pupa state,as butterflies and many other insects are known to do, butcontinue active from the time they leave the egg until theydie of old age or some other cause. Two broods are probablyproduced in one season, the eggs of the last brood not hatch-ing until the following Spring. Should this species everbecome numerous, a great amount of damage would be doneto the foliage of the trees or plants on which they feed. Pig. Fig. 187.—Katydid—color, green. Note.—The above insect is frequently mistaken for the truekatydid {Platyphyllum concavum—Harris) which inhabits theeastern part of this country, but has not, so far as I am aware,been found in this State. By comparing Fig. 187 with Fig. 186,1, the differencebetween these two species is readily observable. Remedies.—No. 18; and also by capturing and destroyingthe perfect insects. mSECrS INFESTING THE GRAPE. 208
