C. dyscrilus Mab. rescmble.s the preceding, but the hindwiiig beneath is distinctly nclueons-yellow, (l!/.-«ri/iis. 

 and the genitals are different. Mexico to Peru and the Amazon. 



C. rogersi Kaye has an intense bronze-green reflection on the head, thorax and abdomen. Forewiu"- nujcr.si. 

 dark blackish-brown with 3 white subapical dots; belo\\- the lower cell-angle there is a large, angular, white 

 spot, a small one distally above it. Beneath the base of the forewing is black, the marginal area lighter; on 

 the hindwing the disc is the darkest. Expanse of wings: 40 nnn. Trinidad. 



C. musa Kaije is somewliat smaller, above very similar, beside the spots of the preceding it has yet i»"«'. 

 2 dots cl(3se al)ove each other in the cell-end and another one above tlie middle of the proximal margin; only 

 2 subapical \\hite dots. Beneath the same, with a white inner-angular spot of the forewing, and on the hindwing 

 with a cellular sjjot and (i Avhite postdiscal spots. Expanse of wings: 35 mm. Trinidad. 



C. latonia Schs. (189 i). Above thirk Ijrown, foi'ewing with a fine whitish strigiform spot below the Idionki. 

 transverse vein, with 2 small subapical dots and a larger one behind the lower cell-angle. Hindwmg with some- 

 what darker veins. Beneath on the forewing the costal margin, apex and distal margin are lighter yelloAvish- 

 brown, the proximal margin greyish-whitish; hindwing yellowish-brown, with 5 bluish-white postdiscal spots 

 and a blackish-brown wedge-shaped stripe near the proximal margin. Costa Rica. 



C. hebon Mnb. It is doubtful whether it belongs into this genus. Above blackish-brown with 4 hyaline hihuii. 

 spots, one in the cell, a small one behind it, a large, quadrangular one beneath the lower cell-angle, and a longish 

 one below it; the base of the costal margin is red-brown, tlie fringes are light brown. The hindwing is 

 proximally yellowish, behind the upper cell-angle there is a white c^uadrangular spot, parted by the cellular 

 fold. The proximal margin is very concave with a broad, obtuse anal lobe. The forewing is beneath the same, 

 at the costal margin lighter reddish, at the apex lilat'. the hindwing is red-brown. Expanse of wings: 38 mm. 

 Amazon ( Massauar y ) . 



1-^8. Genus: Oiiophas G. d- S. 



Antennae longer than half the costal margin ; club as in Cobalus. Hindw ing prolonged at the anal angle, 

 middle tibiae .spined. The (^ exhibits a narrow, obliciue scent-scale stripe from the rise of the upper median 

 interruptedasfar as below the lower median vein; above the middle of the sidjmedian there is a transverse fold. 



0. columbaria H.-Schafj. (= flossites Btlr.) (18(3 e) is easily discernible from all the similar species ciIiiviIho-'hi. 

 by the bluish-green head, body and base of wings, and the ochreous-yellow inider smface of the hindwings. 

 Above the forewing is blackish-brown with 2 indistinct, dirty ochreous-yellow, small spots between the median 

 veins. Distributed fi'om Panama to Brazil, and in Trinidad. 



129. Genus: Arotis Mab. 



Antennae as in the preceding. Distal margin of forewing convex, the middle radial vein at its rise nearing 

 the lower one. Middle tibiae without spines. The J" has a treble scent-spot: a straight stripe from the base 

 of the upper median to the lower median vein, and in the submedian area 2 thick spots of erect scales. 



A. sirene 2Iab. Above blackish-brown, distally somewhat reddish. Beneath the base of the forewing ■■^in-ne. 

 is blackish, in the marginal area beautifully violet. Hindwing in the basal half blackish-brown with a white 

 cell-end dot, behind it whitish-lilac, with black veins, at the margin darkened. Brazil. 



130. Genus: Ocm»iiiis G. Sc S. 



Antennae half as long as the costal margin; the middle radial vein at its rise strongly bent downward; 

 hindwing at the anal angle prolonged; middle tibiae spined. An oblique scent-scale stripe extends in the (^ 

 from below the base of the upper median vein to the lower vein near its rise, a short stripe is -situate close 

 below it, and a third in the middle of the submedian vein. 



0. pyste G. d- S. (186 e) is similar to columbaria above, without the intense green hue, only the /'.'/■>/<•■ 

 frons somewhat greenish. It is larger, the 2 spots of the forewing are more distinct, the stigma thinner, more 

 distinct; forewing sometimes with a minute subapical dot. Beneath lighter, the hindwing with 4 yellowisli 

 small dots near the distal margin. Mexico. 



0. nausiphanes Schs. (189 c) is above dark brown, the costal margin of the forewing is somewhat luuLtipitd- 

 scaled yellowish, the black scent-stripe fine; fringes of hindwing yellowish-grey. Beneath the forewing is darker '"''■• 



in the basal halves of the cell and of the proximal margin. Hindwing dull brown with a broad, whitish discal 

 shade, the broadest at the costal margin and not reaching to the proximal margin strewn with grey'ish-Avhite. 

 Costa Rica (Poas). 



0. garinia Schs. Dark brown, fringes greyish-brown; forewing with minute iiyaline spots: a sub- i/ariuiK. 

 apical one, two at the cell-end, a small one behind the lower cell-end, being strangulated in the middle, a qua-
