Among the more grotesque larv« belonging to this family are 

 those of the genus Sckizura, of which we have several species. Figure 

 848 represents the larva of Schizura ipomecB. At the left in the figure 

 is shown a front view of the longest tubercle. This species feeds on 

 oak, maple, and many other plants. In the Gulf States it feeds on 

 Ipomea coccinea, which fact suggested its specific name.

 The Tussock-moths 



The larvae of these moths are among the most beautiful of our 

 caterpillars, being clothed with brightly-colored tufts of hairs; and 

 it is to this characteristic clothing of the larvae that the popular 

 name tussock-moths refers. 



The adult moths are much plainer in appearance than the larvae ; 

 and in the genera Hemerocampa and Notolophus, to which our most 

 common species belong, the females are practically wingless, the wings 

 being at most short pads, of no use as organs o£ flight. 



The tussock-moths are of medium size, with the antennae of both 

 sexes when winged pectinated, those of the males very broadly so; 

 the wingless females have serrate or narrowly pectinate antennae. 

 The ocelli are wanting. The legs are clothed with woolly hairs; 

 when the insect is at rest the fore legs are usually stretched forward, 

 and are very conspicuous on account of these long hairs. The venation 

 of the wings is quite similar to that of the Noctuidae, but in the 

 Lymantriidae the point at which veins Sc + Ri and Rs of the hind 

 wings anastomose is farther from the base of the wing (Fig. 849). 

 In some genera these two veins are separate being connected only by 

 the free part of vein Ri. The tussock-moths are chiefly nocturnal; 

 but the males of some of them fly in the daytime. 



The larvae of our native species are very characteristic in appear- 

 ance. The body is hairy; there are several conspicuous tufts of hairs 

 on the dorsal aspect of the abdomen, and at each end of the body there 

 are long pencils of hairs; on the sixth and. seventh abdominal seg-
