120 TWENTY-FOURTH REPORT ON THE STATE MUSEUM. 



spinous, yellow laterally, brown anteriorly, and with a narrow 

 brown stripe posteriorly. Legs roseate ; prolegs green. 



Second molt. -June 29th, and of the last two larvae, on the 30th (thirty 

 in all). Length at rest 45-100ths; diameter il-lOOths of an inch. 

 Lateral stripes of the head rectilinear from the front of the eyes to 

 the apical tubercles. Body pale green, dorsally whitish green ; in the 

 lateral bands the first three papillae are inconspicuous, and those on 

 the first three annulets of the two following segments are smaller 

 than the others and geminate; on segments one to seven, is a small 

 red spot placed on the seventh annulet, above the snbdorsal and 

 thoracic lines and anterior to the first four lateral bands. Caudal 

 horn slightly curved, yellow, narrowly lined with reddish-brown 

 anteriorly. 



On the morning of July 3d, several had taken their position for molt 

 ing on the under surface of the leaves, suspended by their terminal, 

 and one or at most two pairs of prolegs, with their body hanging 

 downward. On the portion of the leaf beneath them (in most instances 

 a part of the midvein), for about the breadth of the body and two- 

 thirds of its length, a slight webbing of silk had been spun to serve 

 us a foothold. The head was partially withdrawn from its case, 

 showing a transhicency at the tip, and a corresponding enlargement 

 and extension of the first segment. The subdorsal lines had disap 

 peared, while the thoracic lines were still conspicuous in their yellow 

 papilhe. In the larger number of the larvce, the row of small red 

 subdorsal spots was quite distinct, especially on segments five to 

 eight inclusive, where they occupy the seventh annulet and encroach 

 on the eighth. Length at rest, one inch ; diameter 12-100ths of 

 an inch. 



Third molt. July 4-th probably, as when again observed on 

 the r morning of the 6th, all but two had molted, and most of them 

 had increased materially in size, the largest measuring one inch and 

 six-tenths in length. Immediately after the molting, they were one 

 inch and one-fourth long, by M-100ths of an inch in diameter. When 

 their colors had developed, they presented the following appearance : 



Lateral stripes of the head, yellow. Lateral abdominal bands and 

 thoracic stripe, pale yellow with whitish papillae, the bands occupying 

 of three segments, three-eighths, the whole, and six-eighths respectively. 

 Caudal horn straight, acutely granulated, pale violet. Anal shield 

 with white granulations as the body. Legs roseate. Stigmata ellip : 

 tical, dark red : above each stigma (except at the extremities) at
