their cocoons (Plate VI. Fig. 2), which are oval, thin, and 

 hair}-, like those of the other Arctians. The chrysalis is 

 short, thick, and rather blunt, but not rounded at the hinder 

 end, and not downy. The moths, which come out of the 

 cocoons during the month of June, are of a very light ochre- 

 yellow color ; the fore wings are long, rather narrow, and 

 almost pointed, are thickly and finely sprinkled with little 

 brown dots, and have two oblique brownish streaks passing 

 backwards from the front edjie, with three rows of white

semi-transparent spots parallel to the outer hind margin ; the 

 hind wings are very thin, semi-transparent, and without spots ; 

 and the shoulder-covers are edged within with light brown. 

 They expand from one inch and seven eighths to two inches 

 and a quarter or more. The wings are roofed when at 

 rest ; the antennaB are long, with a double, narrow, feathery 

 edging, in the males, and a double row of shoi't, slender teeth 

 on the under side, in the females ; the feelers are longer 

 than in the other Arctians, and not at all hairy ; and the 

 tongue is short, but spirally curled. This kind of moth does 

 not appear to have been described before, and it cannot be 

 placed in any of the modern genera belonging to the Arcti- 

 ans ; for this reason I pro-

joa 21 Caryce (Fig. 175) ; the 

 first name meaning crested 

 caterpillar, and the second 

 being the scientific name 

 of the hickory, on which 

 it lives. In England, the moths that come from caterpillars 

 having long pencils and tufts on their backs are called tus- 

 sock-moths ; we may name the one under consideration the 

 hickory tussock-moth. 



In August and September I have seen on the black wal- 

 nut, the butternut, the ash, and even on the oak, caterpillar* 

 exactly resembling the foregoing in shape, but differing in
