152. Genus: dial copasta Hmps. 
Very similar to the preceding genera, with a well developed proboscis and the same frontal projection 
with a horny plate under it; the palpi are porrect and rather long-haired; the thorax is clad with rough scales, 
in front and behind with loose tufts, the apices of the shoulder-covers rolled somewhat upward, abdomen tuftless; 
the anterior tibiae at the ends inside with a very long strong claw. Several beautiful species decorated with 
large golden spots, all from America, partly very hard to discern. 
C. arianda Drc. (44 i). Forewing as in all these allied species metallic greenish golden, at the costal arianda. 
margin whitish, irrorated with red-brown, here with a reddish-brown quadrangular spot in the place of the 
ring-macula, and a more triangular one at the cell-end with an inwardly bent lower end, therein the strangulated 
reniform macula encircled with red-brown, with some golden scales at the inner margin; base of hind-margin 
likewise reddish-brown, fringe speckled white and brown. Hindwing white, at the margin lined with reddish 
brown. Mexico. 
C. riandana Dyar (44 i) is somewhat smaller and neater; the small quadrangular spot before the centre riandana. 
of the costal margin is absent, the reniform macula is on the median not so far inwardly produced, the basal 
hindmarginal spot is larger, extending to the centre of the hind-margin and despatching a continuation upward 
as far as the median. Mexico (Tehuacan). 
C. territans Edw. (= arizona French) (44 i) is the most similar to arianda and differs in the reniform territans. 
macula being situate in the brown triangular spot and being greenish-golden with a red-brown line in the centre; 
the median is white, the basal hindmarginal spot small; hindwing quite white with a fine red-brown marginal 
line. Arizona. 
C. clialcopharais Dyar differs from territans in the absence of golden colour in the reniform macula; chalcopha- 
the forewing is relatively broad, the reniform-macular appendage of the brown costal-marginal stripe is intensely nis - 
irrorated with white, also in the basal third of the cell a short brown appendage extends downward; a series 
of small feeble brown submarginal spots is more or less distinct as in nearly all the species. Hindwing of a pure 
yellowish-white, without a distinct marginal line. Separated from the following, likewise very closely allied 
species by the hardly projecting frontal appendage. Mexico (City), taken in August. 
C. anopis Dyar (34 i) has a much more distinctly projecting frontal appendage; it is somewhat anopis. 
smaller, with narrower wings; the brown costal margin is more intensely mixed with white, its widening behind 
the cell is only slight, the reniform macula itself brown mixed with white, the hindmarginal spot also very 
much mixed with white. Expanse of wings: 30 mm. Mexico (Cuernavaca), in September. 
C. howardi Ediv. (= ornata Ottolengui ) (44 i) is also extremely similar to the preceding species, the ] wwar di. 
basal area is more extensively brown and white with only a small golden wedge-shaped spot which is distally 
bordered by a red-brown antemedian line. Hindwing towards the margin somewhat more intensely powdered 
with reddish-brown. Arizona. 
C. sinuata Hmps. (44 i) has broad wings and brown hindwings; the brown basal area is extensive, sinuata. 
the distal bordering very oblique extending to behind the centre of the hind-margin and prolonged as a fine 
brown hindmarginal stripe into the distal margin; in the brown basal area which itself is golden scaled, there 
is in the base of the cell a golden spot; behind the latter the brown colour projects far towards the margin; 
before the upper marginal half there is a narrow brown arcuate spot. Mexico (Zacualpan). 
C. pterochalcea Dyar (44 i) entirely resembles riandana from which it is separated by ciliary plain pterochal- 
antennae in the male. Hindwing somewhat more intensely strewn with brown, with a feeble darker subterminal era. 
shadow. Mexico (Tehuacan). 
C. restricta Hmps. (44 k) is very much like pterochalcea, at once discernible by the brown hindwing resiricta. 
with a lustrous coppery marginal half; the golden basal spot does not extend below the submedian fold. Mexico 
(Tehuacan, Guerrero). 
C. ellica Dyar (44 ) has narrower wings, more powdered, not so lustrous, and easily discernible from ell lea. 
its allies by the brown reniform-macular spot being continued obliquely proximad to the centre of the hind- 
margin in the shape of a greyish-brown, distally dentate median shadow. Hindwing brownish-grey with a 
whitish fringe. Mexico (City). 
C. fulgens B. <£• McD. (44 k) is similarly marked as the preceding species, but of quite a different fulgens. 
colouring, golden yellow, somewhat metallic, more like the large species of Stiria, the costal margin and the 
reniform-macular spot strewn with purple white, in the latter the reniform macula is indicated by somewhat 
less white irroration, the large purple basal spot does not reach to the costal margin. Hindwing whitish, distally 
smoky. Arizona. 
C. acantha Drc. (44 k) is a smaller species with dark brown forewings and recognisable by the oblique acantha. 
central golden spot flowing together with a subterminal band which is more or less broken up into small spots; 
at the base there is another large golden spot. Hindwing dark reddish-brown. Mexico and Guatemala.
