P. albangula U.-Schdjf. (174 e) is a charming, tiny in.sect, in which the apex of the forewing is alhangula. 

 ensiformly extended and the margin of the liindwing projects in the middle like a tooth. Above jnirple-brown 

 with deep dark transverse bands and ferruginous spots in a row before the margin of the forewino- and in a 

 treble row above the anal marginal part. Forewing with the 3 subapical, most minute spots and a fourth in 

 the cell-end area. Beneath in the costal and basal parts ferruginous, dusted over and speckled with black; 

 at the anal angle on all the wings lighter yellowish-white with ferruginous markings. It is reported to originate 

 from Rio de Janeiro. 



P. nieris Plotz (174 e) differs only little from the preceding, above black with 2 deeper lilack transverse »»er('s. 

 bands and 3 small white subapical dots. Beneath somewhat duller, tinted more olive. Hindwing extended 

 rather long. Colombia. 



14. Genus : Pyrtlaliis 3I(ib. 



Distinguished from Pellicia by the longer, rectangularly bent antennal chib, the presence of a costal 

 fold in the (^, and a longer 3rd palpal joint. Here the hindwing also shows a hair-pencil at the base of the 

 costal margin and tlie fringed posterior tibiae show 2 pair of spurs. Only one species: 



P. corbulo (Jr. (174 e) looks like a large Pellicia, deep blackish-brown with faded black transverse corhulo. 

 bands and 3 minute subapical spots. In the S the costal margin of the hindwing is of a light reddisli-brown, 

 from which the dark pencil stands out distinctly. Beneath lighter, otherwise marked the same, at the proximal 

 margin of the hindwing and on the ventrum bluish-grey. From Surinam. 



15. Genus : Mj'cteris Mnh. 



Likewise extremely approaching Pellicia and, as there, with the hair-pencil of the hindwing and the 

 swelling of the subcostal veins. The palpi are much longer, rostriform, and have a rather pointed, straightly 

 porrect terminal joint. On the hindwing the subcostal vein rises much nearer at the base. No costal fold. 4 

 species are known: 



M. caerulea Mah. (174f). Above almost uni-colourecl brownish-black, particularly in the $ with caeruha. 

 traces of darke)' bands, at the costal margin of the hindwing somewhat lighter. Beneath lighter, the proximal 

 margin of the forewing lilac-grey, the proximal half of the hindwing light greyish-blue, in the $ darker. Guate- 

 mala to Colombia. 



M. tyana PIolz (174 f) is similar, somewhat smaller and with a lighter, violettish- or pmple-grey fyana. 

 costal-marginal area of the forewing, in which the beginnings of darker bands are to be noticed in a similar 

 way as in Pellicia costimaculn (174 c). Beneath the proximal half of the hindwing is violettish-grey or bluish- 

 grey, both wings show traces of dark, brown bands. Brazil (Sao Paulo). 



M. cambyses Hew. (174f) is allied to caerulea. Upper surface dee]> blackish-brown, both wings cambysc.s. 

 with a submarginal row of grey spots, towards the apex larger, dying away analwards; the forewing exhibits 

 an indistinct, short grey band from the middle of the costal margin, the hindwing a similar one in the middle. 

 Beneath dark brown, the apex paler, the proximal margin grey; hindwing reddish-brown, the costal margin 

 and 2 indistinct transverse bands darker brown. Bolivia. 



M. crispus Plotz (174f) is above deep purple-brown with a violet shine, with a darkened margin crispn^. 

 and 3 scarcely visible darker transverse bands similar to the Pe7/icm-spccies; between the distal band and the 

 margin the ground-colour appears lighter. The under surface is also very dark, without any marking, the inner- 

 marginal area of the forewing brownish, the proximal half of the hindwing lighter, more violettish-grey, with 

 slightly darker veins. Venezuela. 



16. Genus: ^isouiades Hhn. 



Antennal club moderately thick, the pointed end uniformly bent; the 3rd palpal joint shortly porrect. 

 Costal fold absent; shape of wings rather narrow, the cell of the forewing narrow, too. Veins scarcely deviating 

 from Pellicia; hindwing rounded off. Posterior tibiae fringed with 2 pair of spurs. 



N. bromius Sfoll (= fissimacula 3Iab.) (174 f). Above dark l)rown, at the cell-end with a thick, hromiu.'i. 

 black spot with two white pupils; before the apex there are 3 small subapical dots, 2 more between the median 

 and lower radial veins. Beneath much lighter olive-brown, at the anal part of the hindwing more bluish-grey 

 with the spots as above. From Surinam. — The larva, according to Stoll, living on Solanum spinosum, is green 

 with a black head and an interrupted black dorsal line and changes into a lirownish pupa on the upper surface 

 of the leaf being somewhat drawn together by few threads. 



N. pelarge G. d- S. (174 f,g) is perhaps of the same species, above with somewhat more distinct prlargc. 

 bands; beneath the hindwing is much more extensively blue or lilac-grey, towards the costal margin with 3 

 darker bands. Nicaragua.
