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



subalbatus. P, subalbatus Plotz (= subornatus 3Iab., zonula 3Iab.) (174 a). Hitherto only the $ seems to be 



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

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

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

 zuela, Colombia, Brazil. 



geomeiri- P. geometrinus Fldr. (= hadina Btlr., corbinianus Plotz) (174 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 discal macula, the 

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



phalaena. P. phalaena Mab. {Stgr. i. 1.) is apparently very closely allied to geometrinus. 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 cm'ved 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 siu'face is greyish-brown with an ochreous spot in the middle, before it a grey band spotted white 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 

 gi'ey border. Bolivia. 



limaea. P. limaea Hew. (= jabesa Btlr., caeruleus Plotz) (174 a). Forewing similar as in subalbatus, but 



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

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



9. Genus: lipioniacles Hhn. 



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

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

 with 2 pair of spurs and a hair-pencil. 



artemides. Sp. ai'teitiides Cr. (171 a). Forewing blackish-brown with -white scales strewn in the shape of a band, 



several minute discal and subapical hyaline dots. Hind wing 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. 



ahhreviatus. Sp. abbreviatus Mab. (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: Eferula Mab. 



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

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



fibrena. N. fibrena Hew. (= nautes Mab.) (177 e) is above dark brown, the forewing with 11 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 yelloAvish reddish-brown. Expanse of wings: l*/^o inches. Amazon (Tonantins). 



11. Genus: Uracon G. <fe 8. 



In its anatomical marks it is very closely allied to the genus Pellicia, but the posterior tibiae in the ^ 

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

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



biternata. E. bitemata 3Iab. 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).
