PiM. 12. I. 19-24. ONOPHAS; AROTIS; OEONUS. By Dr. M. Draudt. 961 



C. dyscritus Mab. resembles the preceding, but the hindwing beneath is distinctly ochreous-j-ellow, dyscritus. 

 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. Forewing rogersi. 

 dark blackish-brown with 3 white subapical dots; below 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 mm. Trinidad. 



C. musa Kaye is somewhat smaller, above very similar, beside the spots of the preceding it has yet musa. 

 2 dots close above each other in the cell-end and another one above the middle of the proximal margin; only 

 2 subapical \T'hite dots. Beneath the same, Avith a white inner-angular spot of the forewing, and on the hindwing 

 with a cellular spot and 6 white postdiscal spots. Expanse of wings: 35 mm. Trinidad. 



C. latonia Schs. (189 i). Above dark brown, forewing with a fine whitish strigiform spot below the latonia. 

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

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

 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 Mab. It is doubtful whether it belongs into this genus. Above blackish-brown with 4 hyaline hehon. 

 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, the fringes are light brown. The hindwing is 

 proximally yellowish, behind the upper cell-angle there is a white quadrangular 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 lilac, the hindwing is red-brown. Expanse of wings: 38 mm. 

 Amazon (Massauary). 



128. Genus: Onophas G. & S. 



Antennae longer than half the costal margin ; club as in Cohalus. Hindwing prolonged at the anal angle, 

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

 interrupted as far as below the lower median vein; above the middle of the submedian there is a transverse fold. 



0. columbaria H.-Sclitlff. (= flossites Btlr.) (186 e) is easily discernible from all the similar species columharia. 

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

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

 veins. Distributed from Panama to Brazil, and in Trinidad. 



129. Genus: A.rotls 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 Mab. Above blackish-brown, distally somewhat reddish. Beneath the base of the forewing s'vene. 

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

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



130. Genus: Oeoiius G. & 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. ds S. (186 e) is similar to columbaria above, without the intense green hue, only the pysie. 

 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 yellowish 

 small dots near the distal margin. Mexico. 



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

 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 Avith a broad, whitish discal 

 shade, the broadest at the costal margin and not reaching to the proximal margin strewn AA-ith greyish-white. 

 Costa Rica (Poas). 



0. garima Schs. Dark brown, fringes greyish-brown; forewing with minute hyaline spots: a sub- garima. 

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