thuti tlio latter. I'lunax all yellow, as in ^ , witli n.) orange streaks; abdomen orange, distinetly 

 banded with yellow; tips yellowish. 



Fore wings of the same shape as in 0. mjnHs, base of wing yellow, with two long lobes; 

 the discal blolehes inclosed in the broad, large yellow band, wliich otherwise is as iu 9 , extend- 

 ing to costa verv near the apex. Five uneiitial dull orange-l)rown discal blotches, and beyond is an 

 obli(|ue series of six intervenular blotches. A submarginal, scalloped, dark orange line, not 

 reaching the apex; this line not present in C. nyalis. Veins orange. 



Hind wings very diHerent from the other species in being entirely yellow, except two 

 un(M|ual reddish blotches near the base, and an outer broad, diffuse, reddish shade beginning just 

 before the apex and ending distinctly on the inner angle; in 9 the wing is nearly all reddish, 

 with a submarginal zigzag line. 



lender side of wings nearly all yellow; a large, squarish, reddish discal blotch on the fore 

 wings, a more irregular ditluse blotch halfway i)ctween the discal square and apex; outer edge 

 of the w^ing gray orange-red. containing a yellow 5-7-scalloped line. Hind wings all yellow, 

 except the discal spot and the narrow, wavy extradiscal line. For the venation see PI. LVIII, 

 tigs, -i, ia. 



Expanse of fore wings, <J 88.5 nmi.; length of a fore wing, S .39 nun.; breadth of a fore 

 wing, $ ISnim. ; length of hind wing, S 25 mm.; breadth of hind wing, $ 18 mm. 



No locality. In the Edwards collection of the American Museum of Natural History. 

 I have examined 3 S and 1 9 in the Cambridge Museum, and tind that they exactly agree 

 with Boisduval's description. 



One 9 variety, and perhaps laomon Cramer. A large species, with broad, short wings; 

 nmch shorter than in C. regaJln; costal edge more convex; apex squarish; outer edge full and 

 convex, more so than in C. prtnciixdh^ and hind wings shorter, broader, and apex rounder than 

 in that species; the hind wings reach to the end of the al>domen. 



Head and thorax bright ocher yellow, the thorax beinl- entirely j-ellow, with no orange spots. 

 Head deep orange-red in front Imt on the vertex and around the base of the antennte yellow; 

 a narrow transverse orange-i'cd line on the extreme front edge of the prothorax; abdomen 

 orange, narrowly banded with ocher. 



Fore wings with more yellow than in C. regalia; their insertion yellow. No detinite basal 

 and extradiscal lines. Three large discal spots, the innermost round, the others parallel and 

 more or less broken up. The site of the extradiscal line is occupied by a series of intervenular 

 large l)rioht ocher spots, which are rounded on the outer edge, ii'regular on the inner, the 

 longest one being on the costa, the three behind diminishing in size, that in the extradiscal space 

 being the smallest one of the whole series. In the submarginal reddish brown space is a faint 

 irregular zigzag deep orange red line. Fringe of both wings reddish. 



Hind wings with more yellow than in C. rujaUs; ocherous at base as is the inner edge; a 

 large ocherous spot on the costa; the hind wings are more reddish than the anterior ones, and 

 with a coarselv zigzag sulnnarginal reddish orange line edged internalh' with yellow. (The 

 yellow in this zigzag line on both wings may predominate as in Drury's "laocoon.") 



Underside of the fore wings orange at base, extending out on the di.scal cell, and along the 

 inner edge: the extradiscal series of yellow spots as above. The hind wings beneath are j-ellow 

 ocher, a large hemispherical reddish spot; a broad extradiscal reddish line, the outer edge 

 reddish and yellow irregularly diflused. Abdomen yellow on the sides and beneath; a lateral 

 row of reddish spots. 



Expanse of the fore wings, 9 H'' mm.; length of a fore wing, 9 56 nun.; breadth of afore 

 wing, 9 30 nun. ; length of hind wing, 9 38nnn.: breadth of hind wing, 9 27 mm. 



My 9 specimen was compared with examples in the Paris ]Museum labeled C. i.rion. Boisd. 

 It also agrees perfectly with lioisduval's description. 



From an examination of the collection of this genus in the British Museum, which doe-* not 

 possess Juoriion. I was led to regard my specimen described above as a variety of ('. plutroiua. It 

 is intermediate between that and the t^'pe of Walker's E. caclcus. The thorax is yellow as in
