OF THE STATE ENTOMOLOGIST. 89 



when the Epimenis is never seen ; and thouiijh it may be single- 

 brooded in the more northern States, there are two broods with us, 

 the moths from the first brood of worms frequently appearing twelve 

 days after pupation. When at rest this worm depresses the head and 

 f*''-' ^'^ ] raifes the fore body, Sphinx-like, and, in 



order to transform, it also bores into wood 

 and other like substances, though this 

 habit seems not to be as inveterate in it 

 as in the Epimenis, as Harris states that 

 it burrows a few inches below the surface 

 of the ground and there transforms with- 

 KrDRY.vs GKATA-Feiiuih' -Motii, out forming a cocoon. 

 The moth (Fig. 23) has the front wings milk-white, broadly bor- 

 dered and marked with rust-brown and olive-green ; the hind wings 

 nankeen-yellow, broadly marked, more or less, with pale brown on 

 the hind border. It is seldom seen with us till May, and is most com- 

 mon in July and August. 



The eggs of this insect (Fig. 22 e., /", the adjacent outlines showing 

 natural size) are of curious shape and beautiful structure, and are laid 

 singly or in little groups. They are flattened like the fruit of the com- 

 mon Mallow (Malva), and beautifully sculptured with radiating ribs 

 and delicate transverse lines, the color being faint greenish-yellow, 

 with a crenate black circle near the border. My figures are drawn 

 mostly from memory and from notes made while with my friend, 

 Mr. Saunders, who obtained them from the moth in July, 1870. This 

 species is less common with us than the preceding, and seems to flour- 

 ish best in more northern latitudes. 



EuDRYAS GRATA — Egg. — Ffatteiietl, the periphery quite circular : diameter 0.035 

 inch ; thickness not more than } the diameter. A central cell bordered with dusky, 

 and surrounded with a ring of smaller cells, from which radiate about 30 series of cells, 

 more perfect near the center, and only forming parallel crescents toward the border, 

 which is well detined by a crenate black rim; the sides bult^ing- out more or less be- 

 yond this rim. Color translucent-yellow. 



Larva. — Average length 1.50 inch. The ground-color more or less bluish ; in last 

 stage and full grown specimens, quite bluish. Six black, irregular, transverse stripes 

 to each joint, and about 18 piliferous spots, 6 supra- and each side, sub-stigmatal— all 

 except that just behind stigmata and another above prolegs, more or less comiected 

 with the two middle dark stripes; several additional black specks; the two middle 

 stripes fartliest apart and the space between them orange. Head yellow with 9 black 

 piliferous spots to each cheek (G .around ocelli and three above), the upper one accom- 

 panied behind by one or two blaciv specks; alsoG such spots in pairs around epistomal 

 suture, the upper and lower pairs more or less confluent; there are also 2 spots on la- 

 bium ; 2 on mentum ; 2 on the cardinal piece of maxilke, and several on the leg?. On 

 the cervical shield they are arranged as at c, and on the posterior hump as at d. Black
