and colored, and feed on the apple tree and various garden 

 vegetables. The males have very broad wings, with very 

 broadly pectinated antennae, and fly in the hot sunshine in 

 September. The females are wingless and often lay their eggs 

 on the outside of the cocoon, and then die, scarcely moving 

 from their eggs. 0. antiqva Och. is tawiry brown, while 0. leu- 

 costigma Smith is dark brown, with a lunate white spot near 

 the outer angle. 



The thick and woolly-bodied, pale yellowish, crinkled-haired 

 Luyoa is an interesting genus. The tip of the abdomen is very 

 broad, and the antennae are curved and broadly pectinated, 

 while the wings are short and broad. The larva is veiy densely 

 pilose with short, thick, evenly cut hairs, those at the end being 

 longer and more irregular. It is broadly oval, and might easily 

 be mistaken for a hairy Limacodes larva, for, like it, the head is 

 retracted and the legs are so rudimentary as to impart a glid- 

 ing motion to the caterpillar when it walks. Larjoa crispata 

 Pack, is so named from the crinkled woolly hairs on the fore 

 wings. It is dusky orange and slate-colored on the thorax and 

 low down on the sides. Previous to the last moult it is whitish 

 throughout and the hairs are much thinner. The larva (Fig. 

 218) feeds on the blackberry, and, according to a cor- 

 respondent in Maryland, it feeds on the apple. The 

 cocoon is long, cylindrical and dense, being formed of 

 the hairs of the larva, closely woven with silk. The 

 pupa is very thin, and after the moth escapes, the 

 thin skin is found sticking partially out of the co- 

 coon, as in Limacodes and its allies (Cochlidiae). 

 rig. 218. This last group of genera is as interesting as it is 

 anomalous, when we consider the slug-like, footless larvse, 

 which are either nearly hemispherical, boat-shaped, or oblong, 

 with large fleshy spines, and are painted often with the gayest 

 colors. The pupae are very thin skinned, and the cocoons are 

 nearly spherical. The moths are often diminutive, the larger 

 forms being stout, woolly-bodied and with short, thick antenna?, 

 pectinated two-thirds their length, while the smaller genera 

 with slender bodies have simple filiform antennae, and closely 

 resemble some of the Tortrices.
