ous yellow lines across the surface, and a cluster of 
small yellow spots towards the centre. The upper 
wings are yellow beneath, with a black ocelliform 
spot in the middle, with a white pupil, behind 
which is a transverse reddish ray. The under wings 
are yellow above, witli a large central ocelliform 
spot, which is black, with a white elongated pupil ; 
behind this eye there is a black semicircular band, 
succeeded by another parallel one which is ferru- 
ginous ; the inner margin of the wing is likewise 
ferruginous. On the under side the wings in ques- 
tion are yellow, with a transverse ferruginous ray. 
The caterpillar is rather thick and fleshy; light 
green, with a lateral stripe of ferruginous and white, 
commencing at the fourth segment from the head 
and terminating at the anus ; each segment bears a 
transverse row of large tufts of hair. It may be 
called polyphagous, feeding on Indian corn, dog- 
wood, sassafras, &c. The pupa is very dark brown, 
approaching to black, and if Abbot's delineation be 
correct, free from hairs. The author just alluded 
to found the caterpillar spin up on 27tli September, 
and the fly appeared on the wing on the 17th of 
May, and continued coming out at different times 
till the 15th of August following. The caterpillar 
stings very severely, and encloses itself in a brown 
web on the leaves. It is not very common, and is 
a very tender fly to keep in cabinets, the male 
sooner decaying than any other. When young, the 
caterpillars feed in large companies, but ultimately 
become solitary.
