Arctia anna (persephone). 



The eggs were deposited by a female, collected June 1 1, and sent 

 me by Mr. Dearden. I identified the moth from the Edwards collec- 

 tion in the American Museum of Natural History, New York. The 

 eggs hatched about July lo or 12. The female had a broad black mar- 

 gin on the hind wings, and a discal crescentiform spot, otherwise it was 

 normal. Stage I was described July 13. 



Larva, Stage I. — Length 2 mm. Body of the usual shape. Head 

 dull amber, with two dusky spots on the vertex. Tubercles dark chest- 

 nut brown, those of the four dorsal rows of the abdominal segments 

 bearing two setae; the other tubercles, /. e., those of the two lower rows, 

 I -haired. The hairs all dark, spinulate, about one-third as long as the 

 whole body. The prothoracic plate is crescentiform. Thoracic legs 

 amber-colored. It molted July 30, 31. 



Sto.ge II. — Length 6.5 mm. The tubercles now bear from 8 to 10 

 black setse. Body pale ; the large dorsal tubercles black, with minute 

 black non-setiferous ones in front near the front edge of each abdomi- 

 nal segment. Lateral tubercles pale, of the color of the body, but with 

 black setae. Prothoracic shield small, dark, not conspicuous. Two 

 long black hairs project beyond the others from the end of the body, 

 and two similar ones from the side of the 8th abdominal segment. 

 Head dark chestnut above, in front pale. Ground color of the body 

 greenish, the tubercles yellowish. Thoracic and abdominal legs pale. 



August 8th, it had not molted ; length 10 mm. Now all the tuber- 

 cles are black, and the skin is livid, with faint traces of two dorsal lines 

 between the two rows of large dorsal tubercles, the lines enclosing the 

 minute anterior tubercles. 



After second molt, August 14. Length 10 mm. The body is now 

 nearly concealed by the dense hairs. Head black. The hairs along 

 the back black, those low down on the sides arising from the lowest 

 row of tubercles snuff yellow. 



Arctia phyllira. 



The eggs were laid about June 1 7 at Providence and with the moth 

 was given me by Mr. Dearden. The $ specimen was compared with 

 those in the Edwards's collection in the American Museum of Natural 

 History, and were nearly of the normal form. The eggs hatched June 

 20-21, and the larvre were reared at Brunswick, Me. 



Larva, Stage I. — Length 3 mm. They had been eating perhaps 

 two days. The head was not so wide as the body and shining black. 

 The body is deep, amber colored, the tubercles darker, dark brownish,
