ARTEUROTIA; SOPHISTA; CELAENORRHINUS. By Dr. M. Dratjdt. .885 



3. Genus: Arteiirotia Bth. <&: Drc. 



Only one conspicuous species owing to the hindwing being considerably prolonged at the anal angle and 

 showing a silky lustrous scent-scale spot in the apical half above. ^ without the costal fold. The antennal 

 club is strong, bent, the final point shorter than half the length of the club, the short 3rd palpal joint obtuse 

 conic. 



A. tractipennis -B<?r. (= ribbei Stgr.) (172 g) is above olive-brown, before the apex of the forewing tractipen- 

 with a velvetj'-brow^n triangular spot, in it one, behind it 2 small hyaline spots, before the somewhat darkened 

 border a lighter antemarginal line, in the basal half at the costal margin and below the cell small dark spots. 

 From Mexico and Panama. 



4. Genus: ISophista Plotz. 



Antennal club thinner than in the preceding, the final point very slender. Palpi as in the preceding. 

 Hindwing not so much prolonged, more of the shape of a broad lobe, and without the scent-spot; the lower 

 median vein rises in the middle between the base and cell-end. The costal fold of the ^ is but slightly developed 

 or absent. Three very similar species. 



S. aristoteles Dhl. tfc Heiv. (172 g). Black, towards the margin with 2 brownish undulately dentate arisiotcles. 

 lines before the somewhat speckled fringes which are bent inward at the apex of the forewing. The middle 

 of the wings is crossed by a white band very broad particularly on the hindwings and extending on the forewing 

 only to the upper median vein and ending broadly rounded above, whilst on the hindwing it extends broadly 

 to the proximal margin. Rio Negro (Amazon). 



S. plinius Plotz (172 g) is extremely similar, of a somewhat duller shade, the white band narrower, plinius. 

 ending upward pointed on the forewing, rounded off on the hindwing, the whole proximal margin being left 

 black. Novo Friburgo, Bolivia. 



S. calendris Hew. (= clinias Mob., epipola Plotz) (173 a). Here the white band on the hindwing calendris. 

 has changed into a narrow, bent median line parted by the veins, whilst on the forewing it is entirely absent. 

 The distal part of the hindwing and an indistinct transverse band on the forewing are dusted bluish-grey, on 

 the forewing there are inside and outside of it several small hyaline spots, before the border of the hind- 

 wing small black internerval spots. Guiana, Amazon. 



5. Genus: Celaeiiorrhiuus Hbn. 



The antennal club is only moderately thickened; the palpi are ascending, the 3rd joint very short. The 

 hindwing is here quite round, the distal margin somewhat undulate; the transverse vein is very feebly developed, 

 the middle radial vein scarcely present, the lower median vein rises mvich nearer at the cell-end than at the 

 base. The posterior tibiae exhibit 2 pair of spurs, the cj has besides a hair-tuft at the proximal end. The 

 species are preferably distributed in the Indo- Australian region, about half a dozen are nearctic. 



C. eligius Cr. (= hiera Plotz) (173 a) is above brown, in the apex of the forewing there are eligiiis. 

 3 large hyaline spots, below it 2 small ones, in the disc 2 very large ones, behind them 1, below them 2 small 

 ones, at the costal margin a somewhat larger hyaline spot; before the margin and on the hindwing, also 

 in the disc, several small, lighter spots. The under surface is a little duller, on the hindwing the small light spots 

 are more distinctly prominent. From Mexico and South America, widely distributed. — From the Rio Songo 

 from Bolivia there are specimens before me from Fassl: — songoensis form. nov. (173 b) — of a smaller and songoensis . 

 neater habitus; the small subapical spots are reduced to small dots, of which the middle one of the 3 upper 

 ones seems to be placed more proximad, the discal hyaline spots are lilcewise smaller, the hindwing slightly 

 rounder. 



C. fritzgartneri Bail. (= variegatus G. cfc *S.) (173 b) on an average is somewhat larger than eligius frif:garf- 

 with somewhat narrower wings, the hyaline spots smaller, below the middle of the cell another minute, dark- '"^'■^• 



ringed spot. Hindwing in the disc lighter with a larger dark discal spot and a similar macular band behmd it. 

 Mexico and Central America. It flies in December, rests on the keystones in dark tunnels and caves, and on 

 being scared up it flies furiously about, though not into the open air. 



C. shema Hew. {= ochrogutta Mschlr.) (173 b) is smaller, darker, the hyaline spots smaller, more shema. 

 uniformly round and more distantly separated. A small discal spot and behind it a curved row of mmute round 

 spots on the hindwing are yellowish, beneath still more distinct, and near the base there are 3 more. Fi-om 

 Cayenne. 



C. monartrus Plotz (= chiriquensis Mab.) (173 b) has still much smaller spots, the hindwmg as monarirus. 

 in fritzgartneri, but darker. Mexico to Panama.
