species 



these are egg-shaped or nearly spherical, and are furnished at one end 

 with a cap which can be pushed aside by the adult when it emerges 

 341). The cocoons are usually spun between leaves. 



The moths are of medium or small size; the 

 body is stout, and the wings are heavily and loosely 

 scaled. The maxillae are vestigial. These moths 

 vary greatly in appearance, and many of them are 

 very prettily colored. 



The following are some of the better known 

 of this family. 



The saddle-back caterpillar, Siblne stimulea. — This larva 

 can be recognized by Figure 342. Its most characteristic 

 feature is a large green patch on the back, resembling a saddle- 

 cloth, while the saddle is represented by an oval purplish-brown spot. 

 The moth is dark, velvety, reddish-brown, with two white dots near the 

 apex of the fore wings. The larva feeds on oaks and other forest trees. 

 This is one of the species that are armed with venomous setae. 



The spiny oak-slug, Euclea delphinii. — This larva (Fig. 343) is one of 

 the most common of our slug-caterpillars and one of those that are armed 

 with venomous setae. It feeds on the leaves of oak, pear, willow, and 

 other trees. The moth (Fig. 344) is cinnamon-brown, with a variable 

 number of bright green spots on the fore wings.

The hag-moth, Phobetron pithecium. — The common name hag-moth 

 is applied to the larva of this species on account of its remarkable ap- 

 pearance (Fig. 345). It bears nine pairs of fleshy appendages which are 

 covered with brown hairs. In the full-grown larva the third, fifth, and 

 seventh appendages are longest; these are twisted up and back, and 

 suggest the disheveled locks of a hag. This larva feeds on various low 

 shrubs and the lower branches of trees. At the time of spinning, the 

 larva sheds the fleshy processes, and they remain on the outside of the 

 cocoon. 



Family Tineid.-e 



The head is usually clothed with erect hair-like scales. The antennae 

 are shorter than the front wings. The maxillae are usually small or 

 vestigial. The maxillary palpi are usually large and folded. The labial 

 palpi are short and clothed with bristles. In the typical genera the
