A second brood of the little miners works onthe leaves in September and during October they fasten theircases to the bark and hibernate therein as quite serious outbreaks of this tiny shield-bearer. 76 FRUIT INSECTS have occurred at Washington, in Connecticut and in Michiganon apple, quince and wild cherry, sometimes 25 or 30 minesoccurring in a single leaf. The bark of the trunk and largerbranches were fairly covered with the hibernating cases, 47having been counted on a spot not larger than a dime. ReferenceComstock, Kept. U. S. Ent. for 1879, pp. 210-213. Natural enemies of the lesser leaf-miners of the apple. All of these little leaf-miners have enemies which are moreor less effective aids in preventing their occurrence in injuriousnumbers. At least two tiny Chalcid parasites, Sympiesisnigrifemora and Astichus tischeriae attack both the spottedand unspotted tentiform-miners. Ants often tear open thecases of the resplendent shield-bearer and devour the inclosedcaterpillar or pupa; two minute hymenopterous parasites alsoattack this miner. We have bred a tiny parasite from theserpentine miner, and many of the scale-like hibernatingcocoons have been found
