890 SPIONIADES; NERULA; ERACON. By Dr. M. Draudt. 



sKbanafus. P. subalbatus Plolz (= subornatns Mab., zonula Mab.) (174 a). Hitherto only the $ seems to be 



known; above blackish-brown with a median band formed of blue scattered scales on both wings and 3 small, 

 white subapical dots on the forewing. Beneath the anal half of the hindwing is white with a blackish antemarginal 

 line; the bordering towards the base is brightened up in a bluish grey and tinged brownish-red. Panama, Vene- 

 zuela, ('olombia, Brazil. 



r/eomeiri- P. geometriiius Fldr. {— hadina i?//c., corbinianus P/d/2) ( 1 74 a) has brown wings being lighter towards 



""«■ the margin, traversed by 2 darker transverse bands bordered by a lighter colour and parallel to the distal margin. 

 Beneath lighter, on the forewing strewn with a reddish yellow and with a reddish-yellow di.«cal macula, the 

 hindwing scantily strewn with whitish, and with 2 whitish transverse lines. Panama to Southern Brazil. 



phalaena. P. phalaena Mab. (Stgr. i. 1.) is apparently veiy closely allied to (jeometrvmis. Yellowish brown 



, with black transverse bands across both wings; the base brownish, behind it a black, distally bent band across 



the cell-end; on the hindwing the band is narrower: .a proximally curved postmedian band terminates on the 

 fore- and hindwing at the proximal margin with a thick black spot; at the margin another broad band. The 

 under surface is greyish-brown with an ochreous spot in the middle, before it a grey band .spotted \^hite at the 

 proximal margin, behind it a grey band being ochreous-yellow below the cell and terminating in a grey spot 

 bordered with yellow. Hindwing bluish greyish-white, at the base brown with a grey median band and a blackish 

 grey border. Bolivia. 



limaea. P. Hmaea Hew. (= jabesa Btlr., caeruleus Plolz) (174 a). Forewing similar as in svbalbahis, but 



the hindwing with a broad blue marginal band. Beneath the hindwing is extensively blue with a more or less 

 spotted blackish-brown costal max'gin, often there is only one spot at the costal angle. Brazil (Amazon). 



9. Genus: ^piouiatles Hbn. 



Antennal club moderately thick with a short, bent apex; the 3rd joint of the porrect palpi is hidden. 

 The apex of the forewing somewhat stunted. The costal fold is absent. Hindwing prolonged. The posterior tibiae 

 with 2 pair of spurs and a hair-pencil. 



artemides. Sp. artemides Cr. (174 a). Forewing blackish-brown with white scales strewn in the shape of a band, 



.several minute discal and subapical hyaline dots. Hindwing in the anal half white, in the (J tinted somewhat 

 brownish with a more or less distinct marginal band before the fringes. From Panama through Guiana to 

 Southern Brazil. 



abbreviatiis. Sp. abbreviatus 2Iab. (174 a) is somewhat larger, the forewing shorter and broader with larger hyaline 



spots, the hindwing not so much prolonged, the white anal part of the hindwing reduced, the marginal band 

 divided into spots, the lowest more distantly remote from the proximal angle than in the preceding. Nicaragua, 

 Costa Rica, Panama, Colombia to Bolivia. 



10. Genus : Xerula Mab. 



In the characters it entirely coiTesponds to the genus Cogia of the preceding group, but the cell of 

 the forewing is shorter than ^/g of the length of the costal margin. Only one species: 



fibrena. N. fibrcna Heir. (= nautes Mab.) (177 e) is above dark brown, the forewing with II hyaline dots: 



one at the costal margin, 2 in the cell, and one below it of the shape of the number 2; farther towards the 

 margin 3 and an isolated one above it and 3 subapical ones. The hindwing exhibits at the base a tuft of yellowish- 

 red hair, the anal angle is broadly white, parted by a brown band. Beneath the same, only of a paler tint ; hind- 

 wing entirely white, costal margin, 2 spots below it near the base, an irregular transverse band and a spot 

 at the anal angle yellowish reddish-brown. Expanse of wings: l*/j(, inches. Amazon (Tonantins). 



11. Genus: Eracoii G. & S. 



In its anatomical marks it is very closely allied to the genus PeUicia, but the posterior tibiae in the 5* 

 exhibit a long hair-pencil, and the prolonged hindwing shows above at the base of the costal margin a hair- 

 tuft. The forewing exhibits a black spot in the cell as in Cyclosaemia. 



biternain. E. biternata Mab. is dark brown with 3 darker transverse bands, in the disc of the forewing with a 



large black spot with two white hyaline dots in it and one above it; 3 minute, subapical, white hyaline spots 

 in a triangle. Beneath lighter and more reddish brown. The body beneath is whitish. Panama (Chiriqui).
