It has been recom-mended that hogs be kept inthe orchard for the purpose ofdevouring such fruit; and,where they can be so keptwithout injury to the trees orto other crops, they will nodoubt prove useful. This insect, while in the lar-val stiite, is so protected withinthe apple that it enjoys greatimmunity from insect enemies. Nevertheless it is occasion-ally reached by the ever-watchful Ichneumons, two species Fig. 132 INSECTS INJURIOUS TO THE APPLE.

One is a smallblack fly, from one-fourth to one-half inch in length; its legsare reddish, the hind pair having a broad white ring. Itis called the Ring-legged Pimpla, Pimpla annuHpes Br., andis represented, much magnified, in Fig. 139. The other species is about thesame size, but moreslender, and of ayellow or brownish-yellow color. Thefemale is providedwith a long ovipos-itor, as seen inFig. 140, where theinsect is shownhighly abdomen of themale is representedto the right of thefigure.
