EREBIA III. 



the middle of the segment; on 13 are two rows with six tubercles, made from 

 the dorsal and sub-dorsal, which here come nearly into line, a lateral on either 

 side, in front, and six around the end, jirojecting horizontally (Figs. J/, h'^); 

 the interior four small, with somewhat shorter processes ; the processes on 2 

 are thickly clubbed (Fig. Jy'), on the following segments to 12 are lono-er and 

 scarcely clubbed (Fig. ¥), on 13 cylindrical, and still longer (Fig. h') ; alono- 

 base a row of- minute tubercles witli short hairs, two to each segment on 2 and 5 

 to 13, one on each of the rest ; color greenish-white, with a mid-dorsal brown 

 line, and three similar equidistant lateral lines, the space between the second 

 and third specked with black or dark brown; under side, feet and legs paler; 

 head a little broader than 2, subglolnilnr ; covered with shallow pits, marked by 

 a few low subconical tubercles, blackish, each with light hair. (Fig. h ; cro.ss 

 section, middle segments, Ir.) Duration of this stage six to seven days. 



After first moult: length, at twelve hours, .2 inch ; nearl}^ same shape, thick- 

 est at 2, tapering gradually to 11, tlien rapidly, curving roundly to extremity, 

 13 ending in two short conical tails (Fig. c'') ; the tubercles similar to tiiose at 

 first stage, but much more numerous, bent, arranged irregularly in both horizon- 

 tal and cross lines, those on 2 decidedly, on segments to 12 slightly, club-shaped 

 (Fig. c*), on 13 nearly cylindrical, gradu.ally tliickening towards end {c'') ; color 

 greenish-yellow, as are also the under side, feet and legs ; a mid-dorsal blackish- 

 brown stripe, on the side three narrow, equidistant, brown stripes ; the basal ridge 

 yellowish, and under it a brown line ; head as before, subglobular, pitted, with 

 many fine tubercles, and short processes and hairs ; color green-yellow. ,'Fig.s. 

 c, c^, section of side and dorsum, segment 7.) To next moult about ten days. 



After second moult : length, at twenty-four hours, .28 inch ; shape as before, 

 tails as before ; the tubercles and processes much more numerous ; color green- 

 ish-yellow ; a mid-dorsal heavy brown stripe, three light ones on side, equidis- 

 tant ; the basal ridge more yellow, and beneath it another brown stripe ; under 

 side, feet and legs pale green; head as before, yellow-green. (Fig. d; cP, cross 

 section.) 



After third moult : length, at twenty-four hours, .38 inch ; scarcely differs 

 from the last preceding .stage, the tubercles still more numerous, bent close to 

 the bod}'. (Fig. e, section of side of segment 7 ; e^, across dorsum of same.) 



Some weeks after the moult, one of the larvaj having reached the length of .6 

 and two of about .5 inch, they became lethargic, and were taken to Clifton 

 Springs, New York, and placed in the refrigerating house there, the temperature
