while the proximal one of these bands here is about 7 mm broad anteriorly, in evalthoides it only attains 4.5 mm. 
In evalthoides the yellow median spots of the hindwing are merged together to form a continuous band, and in 
evalthe they are separate from one another, the red marginal spots of the latter form are seven in number and 
smaller, at least anteriorly, than in evalthoides (3 a). I consider Bolivia the typical locality for the last-named 
form. 
C. viryi Bsd., from C. America, differs from evalthe especially in the absence of the distal transverse viryi. 
band of the forewing. 
C. euphrosyne Perty (= pertyi JJuchecker) (2d), from Brazil, differs from evalthe especially in the differ- cuphrosyne. 
ent shape of the yellow and red markings of the hindwing. 
C. syphax F. (= harmodius Stoll) (2 d), from Brazil and Cayenne, has no yellow markings on the hind- sypha.r. 
wing, and a curved row of spots takes the place of the distal band of the forewing. 
C. mafhani Oberth. (3 c), from the Amazon, has the band of the forewing obsolescent, but the subapi- mathani. 
cal spots sharply defined; the spots on the hindwing small. 
(J. Porewing blackish with two obsolescent light transverse bands, usually connected in the middle, the proximal 
one of which is elbowed (open proximally). Hindwing at least with light median marking. Large insects. 
C. schreibersi Milcan (= latreille Godt., ctesiphon Hbn.) (3 b) is in its principal form characterised by schreibersi.

C. zerynthia G. B. Gray ( = langsclorffi Men.) (3 a), from Brazil and Bolivia, judging from the six zerynthia. 
specimens before me, is darker on the forewing, more blackish (only slightly suffused with green) than our figure. 
H. Porewing greyish or brownish with markings similar to those of Gr, and more or less obsolete. Hindwing with two 
or three rows of whitish or reddish spots which are rather close together and sometimes assume the shape of bands. Small or of 
medium size. 
C. phalaris (F.)Godt., Bsd. (= mygdon Wiv. p. p., mimon Hbn. (?)) (4a, as mygdon). In determin- phalaris. 
ing this species I agree with Boisduval, not Westwood, and, like the former, distinguish mygdon, although 
not as a distinct species. The insect figured by Westwood as phalaris is subvaria Wlcr., which I consider with 
Kirby as a distinct species; I do not understand, however, why Kirby quotes Westwood’s figure under his 
(Kirby’s) phalaris. And as Godart, the first monographer of the group, applied the name phalaris to the 
same species which Boisduval also called phalaris, it follows that the name must be retained for this form and 
no other. -—- From mygdon [Dahn.) Bsd. (Westw. p. p.) phalaris is distinguished by its (usually?) larger size: mygdon. 
according to Boisduval up to 120 mm. in expanse; the largest specimen before me measures 95 mm., mygdon 
only 55 to 70 mm; the spots of the two transverse rows on the hindwing are white in phalaris, occasionally 
with a yellowish edge, while in mygdon they are yellowish; within the proximal one of these rows light spots 
are usually visible, this appearing rarely to be the case in mygdon-, on the underside also the spots of the 
hindwing are usually white and sharply marked, while in mygdon they are yellowish and diffuse; the white 
markings of the underside of the forewing large and sharply marked, in mygdon yellowish. Entire colouring 
of mygdon darker. — Both forms described from Brazil. 
C. subvaria (= phalaris Westw. nee F.) (4 a, as phalaris) has actually the wings of the same shape subvaria. 
as the form subvariana form. nov. (4 a, as subvaria ), our figure of subvaria being inexact in this respect, dionaea subvariana. 
Hpffr. is a smaller form (length of forewing 26 mm.). —- Brazil. dionaea. 
C. albofasciata Schauf. ,,Larger than mimon, above with the same markings, but the forewing on each albofasciata. 
side of the brown transverse band with a narrow white edge filled in with diffuse white scaling, hindwing 
with three rows of white spots edged with black and cinnamon-brown, similar to those of phalaris, but the 
white colour predominant; underneath very like the preceding (perhaps only its $?). Lat. 88 mm.” -— Brazil. 
C. sora Druce, from Paraguay, has the forewing dark brown, similar in markings to C. mygdon, but sora. 
darker; fringes brown. Hindwing black; a large dark orange yellow spot at the apex of the cell, and two 
bands of large dark orange yellow spots from the costal margin to the anal angle, the first band, just below 
the cell, the second along the margin, fringes yellow. Body and extremities dark brown, anus yellow. 3 82.5, 
$ 95.4 mm. 
C. chelone Hpffr (2 c), from Mexico, is characterised by the greyish colour of the forewing and the chclone. 
peculiar curved and almost band-shaped rows of light spots on the hindwing. 
C. argus Bsd. (6 a) recalls phalaris, but can be easily distinguished by the rows of red or reddish argus. 
yellow spots of the hindwing. — Brazil. 
C. orestes Wkr. (= umbrata Men.) (3 b), from Brazil and Venezuela, resembles the otherwise so dif- orestes. 
ferent zerynthia (3a) in the markings of the abdomen and hindwing. — leopoldina form, nov., from Leopoldina leopoldina.
