P. perplexa Schs. <$. Body similar to guapa Schs. Abdomen above dark grey with a black dorsal 
and lateral line, beneath whitish. Forewing blackish with a red costal streak at the base, grey hyaline streaks 
in and below the cell, a black longitudinal line in the cell, a broad, grey-dusted light cell-end spot, four whitish 
hyaline subapical spots and white marginal spots. Hindwing whitish hyaline, veins, costal and distal 
margins black, the latter with white submarginal spots, a broad black transverse vein and a blackish proximal 
margin. Expanse: 59 mm. Costa Rica. 
P. montezuma Schs. (64 f). $ body as i n humeralis (64 d, e). Abdomen above grey. Forewing likewise 
as in humeralis, hindwing yellowish-white with a black, yellow-spotted distal margin which is broader than 
in humeralis, transverse vein broad black. Expanse: 85 mm. Mexico. 
P. rorata Wkr. I was unable to place this species. $ dark red-brown, abdomen spotted white, at 
the end ochreous-yellow, laterally with a white subdorsal stripe, beneath white. Eorewing spotted white with 
short, broad, slanting white stripes across the transverse vein. Hindwing yellow with a broad dark red-brown 
margin, which contains beneath white submarginal spots. Length of wings: 45 mm. Colombia. 
17. Genus: Dysscltema (Anthomyza Sums.) 
This genus, on the whole, agrees with Pericopis, but the $ antennal pinnae are longer, at least as long 
as the diameter of the shaft, and the 2nd radial in the forewing is mostly separate. The 3rd palpal joint is 
short, less than % of the second. They are a striking imitation of the Danaidids, and are very similar to 
species of Thyridia and Ituna. 
D. tiresias Cr. (— swainsoni Drc.) (64 e). Body black, head and thorax dotted white, abdomen 
above blackish-brown, two fine lateral lines yellow, beneath yellow. Forewing black, basally with some white 
dots and a yellow inner-marginal spot, above the centre of the cell with a yellow transverse band which terminates 
on the axillaris before the tornus, a yellow subapical-band between the 1st cubitus and 5th radial branch; in 
the yellow bands the veins are black. A more or less complete row of white antemarginal spots. Hindwing 
yellow, slightly hyaline, veins black, costal and distal margins broad black, the latter with white submarginal 
spots; transverse vein hardly broader black than the other veins. — According to a drawing by Dr. Seitz from 
life, the adult larva is black, with dense, tufted hairing of hard prickles on tubercles, somewhat like in the 
larvae of Ecpantheria, the 3rd, 6th and 11th rings being light lemon-coloured. The lustrous brown pupa lies 
in a very thin web, and yielded the imago after 3 weeks. 
D. heliconides Sums. (64 e) agrees with tiresias, but all the yellow markings are here quite hyaline, 
pale yellowish. The transverse vein of the hindwing is broad black, behind connected with the black, here 
projecting distal margin. — obsoleta form. nov. ($ type from Surinam) is without this band of the transverse 
vein and the projection of the distal margin. Guiana, Amazons, Colombia, Peru. 
The following species remained unknown to me, for which reason I cannot guarantee their being correctly placed 
in this genus. 
D. brotes Drc. Head and thorax according to the description quite black, the white basal spots and 
the yellow inner-marginal spot are absent; hindwing pale yellow, with black veins and a black broad margin 
exhibiting only 1 submarginal spot at the apex and four next to the anal angle. British Guiana. 
D. buckleyi Drc. Body as in heliconides (64 e), forewing brownish hyaline, base, a transverse band 
across the cell-end, apex, costal margin, distal margin, and partly also the proximal margin black, costa basally 
with white dots, a yellowish-brown spot on the proximal margin, the white submarginal spots like in the 
preceding. Hindwing brownish hyaline, with a black margin containing white submarginal spots, and black 
veins; $ paler. Ecuador. 
18. Genus : Are Wkr. 
The generic marks agree with those of the following genus, but the distance between the 1st and 2nd 
radials is twice as long as that between the latter and the 3rd to 5th. 
A. niarginata Drury (64 f). Body blackisli-brown, collar, patagia, and costa of forewing a« far as the 
centre wood-coloured. Abdomen above with bluish-grey subdorsal spots. Forewing blackish-brown, with a 
reddish, duskily dusted transverse band across the cell-end, enclosing a costal spot on the transverse vein of 
the ground-colour; in the ^ mostly only this light-edged spot is left. Hindwing blackish-brown, milky-white 
spots near the base in and behind the cell, distally to it a larger and smaller antemarginal spot. Beneath all 
the markings are very faint, costa of forewing with an ochreous-yellow stripe, that of the hindwing with such 
a spot. Jamaica. 
A. mummia Cr. (64 e). Eorewing blackish-brown, its centre wood-coloured, with irregularly inserted 
dark places, which are here and there silvery blue like an antemarginal waved line. Hindwing black, with a 
white iridescent central spot, fringes at the apex white. Smaller than the preceding species. Surinam.
