NYMPHALINAE : FOLYGONIA PROGNE. 367 



yellow ; in front of the spines is a small black spot and sepai-ated from it and from 

 each other by rather broader, pale orange bands, are two still wider inclined stripes or 

 bai's ; a narrow black band unites the laterodorsal spines of the thoracic segments ; the 

 last segment is blackish; there is a very narroAv, pale orange, infrastigmatal line; the 

 l)0(ly beneath is blackish, marked with yellowish, the latter predominating on the 

 seventli antl eighth alxlominal segments. The short spines of the first thoracic seg- 

 ment arc orange colored ; spines of dorsal series pale, seated on orange tubercles, 

 their spinnles pale, excepting those of the eighth abdominal segment which ai'e l)lack. 

 and the spiny bristles are black; those of the laterodorsal series black on the thoracic, 

 pale on tlic abdominal segments, the spinules of the spines of the thoracic segments 

 l)eing black when their insertion is high, orange at base, and ijlack beyond when it is 

 not ; the spinules and hairs of the abdominal spines is as in the dorsal sesies. Spines 

 of the laterostigmatal series like the laterodorsal thoracic spines, but the spinules 

 more extensively orange; the abdominal black, their spinules orange at the base. The 

 spines of the infrastigmatal series are orange or pale with orange or pale spinules. 

 bearing fuscous bristles. The longest spines are those of the laterodorsal series on 

 the thoracic and eighth abdominal segments. The tubercles upon which the spines 

 are so-ated bear also everywhere minute, pale, yellowish papillae, giving rise each to a 

 short delicate hair. Spiracles black. Legs black, the claws reddisli brown; prolegs 

 dark reddish l)rown, covered with orange papillae ])earing short hairs. Length, before 

 the growth of this stage is fully attained, 17.5 mm. ; breadth of body, 3 mm. ; length 

 of longest spines, 2.5 mm. 



Fifth stage (74:31). Head (78:49) brownish fuscous, occasionally tinged Avith 

 ferruginous, the sutures marked with ferruginous ; lower part of the triangle and the 

 sides of the head between the ocelli and labrum, dark greenish vinous. Spiniform 

 tubercles whitish or yellowish, the largest, in the middle of each hemisphere, blackish 

 tipped Avith yellow, all emitting short, luteous or brownish yellow hairs. Summit 

 spines black and some of their spinules whitish. The coronal spine is long and slender, 

 the lateral spinules emitted near the centre, and although also long and slender, not so 

 long as the apical half of the main spine ; above them the main stem sometimes emits 

 occasional short, fine, horizontal hairs from minute raised points. First joint of 

 antennae pale, third blackish, the bristle pale; ocelli black; labrum dark greenish vin- 

 ous; mandibles blackish. 



Body yellowish brown, changing, especially on the sides of the abdominal segments, 

 to dull salmon, and marked with blackish olivaceous; a slender, pale, dorsal line on 

 the thoracic segments ; first thoracic segment blackish and blackish fuscous ; upper 

 surface of the body crossed next the sutures by three or four narrow, alternating, 

 transverse stripes of Ijlack and yellowish brown; the abdominal segments, and espec- 

 ially those provided with prolegs, have a small, triangular, blackish olivaceous spot in 

 front of the dorsal spine; an oblique subdorsal stripe, which is sometimes united to 

 its mate by curving around behind the dorsal spine; broad, curving, lateral and stig- 

 matal sti'ipes, each of which passes between the spines ; and an irregular, infrastig- 

 matal, yellowish line. The spines (86: 68) are furnished high up with five spinules, 

 forming a sort of wi*eath, each spinule placed at an angle of about 60° with the apical 

 portion of the main stem ; there are seldom more than one or two spinules of any 

 magnitude on the lower portion, and the latter is destitute of pile; they ai'e mostly 

 black with whitish spinules and dark rufous bristles, but the dorsal ones of the first to 

 seventh abdominal segments and the laterodorsal ones of the second to sixth abdominal 

 segments are altogether whitish excepting tlie bristles ; and those of the infrastig- 

 matal row are whitish excepting at the base. The short spines of the first segment 

 are white and orange, bearing rufous hairs. The body is covered infrequently with 

 very delicate, short, nearly invisible, brownish hairs, seated on minute, whitish papillae 

 arranged in ti*ansverse rows. Spiracles shining black, narrowly annulated with pale 

 slate color. Legs black, tinged with rufous; prolegs blackish olivaceous, black at 

 tip, the anal pair beset with white papillae giving rise to rufous hairs. Length, 27.5 

 mm. ; breadth of body, 4.25 mm. ; breadth of head, 2.75 mm. ; length of spine on 

 summit of head. 2 mm. : lengtii of spine on second thoracic segment, 3.15 ram.
