232 ORDER LEPIDOPTERA. 



terior wings; Che wide black border margined interiorly with dark gray. Antenna? 

 brown, pectinated in both sexes. Front of the thorax yellow, hairy ; hairs of a rust- 

 color posteriorly. Abdomen black, marked with three reddish rings, and the male 

 has the last ring of the same color. 

 The male and female have a very close resemblance : the male, however, is a little 

 smaller, and has two tufts of reddish hair upon the lateral parts of the thorax ; while the 

 females are marked with forked reddish lines upon the anterior wings, which terminate 

 in the yellow stripe across the thorax. Pupa-case black. 



The caterpillars of this species are of two kinds, or rather are marked after two different 

 patterns. The head and feet are red, and each ring is ornamented with three pair of red- 

 dish compound spines. These spines sting sharply ; and though not at all common, they 

 have been found in an oak and hickory grove three miles south of the city of Albany, 

 together with the larva or cocoon of the insect. The figures were copied from Abbott & 

 Smith's Insects of Georgia.

Satvrnia io. Corn Emperor Moth. 



Antenna? pectinate : head and thorax purplish brown : abdomen ochre-yellow. 



Titer side, male : Color indian yellow. The anterior wings are marked with two oblique 

 wavy lines towards the hinder margin, a zigzag line near the same, and several spots 

 arranged so as to form the letters A H, all of a purplish red color. Posterior wings 

 hairy and purplish, red at the base : on the posterior margin there is also a curved 

 band of the same color ; and within this band is a curved black line, and on the 

 middle of the wing a black spot with a bluish centre, upon which there is a silver- 

 white line or dash pointing to the inner and posterior angle. 

 Female : Anterior wings purplish brown or cream-color when faded, and marked in the 

 middle with a brownish spot. Thorax and legs purple brown. Abdomen same as male. 

 Greatest expanse of wing about three and a half inches. 



The caterpillar measures two and a half inches when fully grown : its color is pea- 

 green, marked on the sides by a brown stripe edged with white, the stripe beginning at 

 the fourth ring. The surface is covered with stinging prickles, standing and spreading in 

 clusters and terminating in black. 



The moth is hatched in July from the pupa, in which state it has remained through the 

 winter. 



These caterpillars feed upon the leaves of the elm, poplar, dogwood and sassafras, and 

 also upon clover and indian corn. During a part of their lives they are social, and, when 

 they move, they march in regular files.
