LIMENITIS I. 



After second moult : Length, .24 inch ; in shape and markings much as at the 

 last stage, )>ut the principal ridges are more elevated and all the processes more 

 prominent ; those of 3, 12, and 13 now largest ; on 13 are four, two at the ex- 

 treme end and directed back so as to form a bifid tail, from the base of which 

 rise two smaller similar ones at an angle of about forty-five degrees ; the dorsal 

 patch buff, and extended partly over 7 and 9 ; the basal ridge buff on last three 

 segments; color of body, blackish-brown, the ends of the processes and tubercles 

 generally lighter ; the larger processes on 3 are not crowned as before, but 

 the upper half is covered with knobs ; head nearly as before, the face black, 

 the upper part and side yellow-lirown, with tubercles. (Fig. d, magnified.) 



Five days after second moult (length .4 inch) each larva had begun to make 

 its case or hybernaculum, and three days later all had entered into them. 



The first larva left its case the 29th March following, at Coalburgh, fed a 

 little, rested, and after two days passed third moult. 



After third moult : length .44 inch ; general color red-brown, somewhat 

 specked and mottled with black, especially at the junction of the segments, the 

 processes ferruginous-red or partly castaneous ; segments 2 to 4 yellowish, in- 

 clining to buff; on dorsum of 3 is a clear buff, smooth, elevated cross ridge, 

 excavated on summit, and giving out at each corner an irregular, compound 

 knobbed appendage, .05 inch long, and wholly red ; between these, in line, two 

 small crested tubei'cles ; on 4 is a narrow and low ridge on which are four red 

 tubercles, the two at the ends largest, and all crested with red knobs ; 5 has a 

 still smaller ridge with little red tubercles, and closelj^ resembles 10 ; on 6 are 

 two large maanmilloid processes, which occupy the whole ridge, and are castane- 

 ous, with fine concolored crests ; 8 is immaculate, yellowish, except low down 

 the sides, where it is encroached on by the brown color ; 7 and 9 have the dorsal 

 parts like 8, but both are specked with red and a little Ijlack ; on these three 

 segments are fine concolored and crested tubercles dorsally ; segments 10 to 13 

 are red-brown, the latter mottled with black ; on 11 are two 'small processes, on 

 12 two larger, on 13 two quite prominent, directed backward ; these last are 

 black with red knobs, and at base of each rises a small upright process ; in ad- 

 dition to the tubercles on the dorsum, are small ones on sides of nearly all seg- 

 ments ; the basal ridge is brown in the middle segments, but after 10 gray-buff, 

 making a distinct band of that color which widens posteriorly ; head obovate, 

 narrow, high, the sides well rounded, the top deeply cleft with a broad suture 

 down the face ; the vertices high and pointed, its whole surface covered with 

 simple rounded or conical tubercles ; those on the vertices rather more promi- 

 nent than elsewhere, and those at back and sides long, conical, and separated ; 

 color of lower face and of the sides of face up to the vertices blackish, the upper
