280 LEPIDOPTEEA. 



Tlie genus Oallimorpha is still larger, with broad wings. 

 C. Lecontei Boisdnval is white, the fore wings being almost 

 entirely bordered with brown. The caterpillars of this genus 

 are usually dark colored, with longitudinal yellow stripes. By 

 day they hide under leaves or stones and feed by night on 

 various shrubby and herbaceous plants. C. interrupto-marginata 

 Beauv. (Fig. 210, fore wing) has an anchor-shaped black spot 

 when the wings are folded, one side of the anchor being seen 

 in the figure. 



Arctia and its allies are stout-bodied, with short, moderately 

 broad wings, and simple or feathered antenna 1 . The hairy 

 larva 1 are covered with dense whorls of long, spinulose hairs. 

 They make a loose cocoon of interwoven hairs under the 

 shelter of some board or stone. The pupa is short and thick. 

 Arctia virgo Linn, is an exceedingly beautiful insect. Its fore 

 wings sometimes expand two inches and a half, and are flesh- 

 red, streaked thickly with broad, black slashes, and on the 

 vermilion-red hind wings are seven or eight large black spots. 



The caterpillar is brown. ^1. Anita Grote 

 is allied, but differs in the wholly black ab- 

 domen and black hind wings. It was de- 

 scribed first from Pennsylvania, and has 

 been detected by Mr. B. P. Mann on the 

 Alpine summit of Mount Washington, N. II. 



The common black and reddish, very hairy caterpillar, found 

 feeding on various garden weeds, is the young of Pyrrliar<-ti<i 

 ixabeUa Smith, a stout-bodied, snuff colored moth. The cater- 

 pillar hibernates, as do most of the others of the group of 

 Arctians, and we have kept it fasting for six Aveeks in the 

 spring, previous to pupating in the middle of June ; it re- 

 mained twenty-seven days in the pupa state, the moth appear- 

 ing early in June. 



Leucarctia differs from Spilosoma in having narrower wings, 

 and the outer edge much more oblique. Leucarctia acrcea Smith 

 is white and buff colored. Its caterpillar is the salt-marsh cat- 

 erpillar, which at times has been very injurious by its great 

 numbers. It is yellow, Avith long hairs growing from yellow 

 warts, and it makes a coarse, hairy cocoon. 



Hijpliantria textor Harris is entirely white. The caterpillar, or
