brown lateral line and green spines tipped with black. Moulted again July 

 29 and 30. Color still brighter pea green. Some of the specimens moulted 

 again between August 5 and 12, bave come nearly to their full size, and 

 have their color completely developed. 



Very pale blue green above, darker green below the lateral line, which 

 becins on the fourth and ends on the eleventh segment, and is red brown 

 above and white below, with a faint edging of brown below the white, 

 particularly across the intersections. There is also on the same seg- 

 ments a lunated spot above and before the prolegs, and on the correspond- 

 in"- parts of the apodous segments, of a red brown color, spotted with 

 gi'cenish yellow. The spiracles are white and are on the brown part of the 

 lateral lines. Legs, prolegs, and side valves of the podex, brown, spotted 

 with pale greenish yellow, the brown color of the valves coalescing with the 

 lateral line anteriorly. Head pale blue green, globular, with brown lip and 

 mandibles, and jet black oceUi. Each segment, with one transverse row of 

 tubercles, surmounted by a many branched set of spines. The tubercles 

 and spines green, rather darker than the skin of the body, and black tipped. 

 The longest branches end abruptly with a more slender, elon- 

 gated, blackish bristle, the shorter ones with merely a black, 

 attenuated point, liach fascicle has from twenty-four to thirty 

 branches, spi-eading from a common centre, in all directions; 

 there are four of these fascicles above the lateral line on the 

 back on every segment, except the eleventh, which lias only three, and the 

 twelfth, which has five, — four in one row and one behind them. On the 

 segments bearing the prolegs, and on the eleventh and twelfth there is, on 

 each side, one fascicle below the latei-al line, and on the other segments 

 tliere are two fascicles below the dorsal series. My description in the 

 Treatise is herein corrected. Several had made their cocoons by Aug. 20, 

 and all by Aug. 27. 



Each dorsal fascicle of spines consists of about thirty, which are green, 

 tipped with a sharp black point, springing from a common centre. In each 

 segment, except the last two, are four fascicles above the lateral line; on the 

 penultimate are only three, the central one the largest; and on the last are 

 five, four in a lateral series, and one central behind. Below the lateral line 

 is a small fascicle in eacli segment, and an additional one still lower in the 

 first four and antepenultimate segments. The fascicles on the first segment 

 arc furnished witli a central branch, whicli is black and blunt at the extrem- 

 ity, and surrounded by branchlets of the same color, blunt, but furnished 

 with a black bristle at the end. 



Colors. Head pea green; lip white; mandibles ferruginous at base, black 

 at apex; palpi and autennules whitish with black tips; region of cyea
