Photograph by M. V. S. these long hairs are numer- ous short spines connected with underlying hypoder- mal poison glands. These hairs are capable of pro- ducing a marked nettling effect when they come in contact with the skin. This species is found in our Atlantic and Southern States. Satisfactory studies of its poisonous hairs and their glands have not yet been made. Sibine stimulea {Em- pretia stimulea), or the saddle-back caterpillar (fig. 32), is another which possesses nettling hairs. This species belongs to the group of Eucleidse, or slug caterpillars. It can be readily recognized by its flattened form, lateral, brist- ling spines and by the large green patch on the back resembling a saddle-cloth, while the saddle is repre- sented by an oval, purplish-brown spot. The small spines are veno- mous and affect some persons very painfully. The larva feeds on the leaves of a large variety of forest trees and also on cherry, plum, and 33o. lo moth larvse on willow.
