B„ carpintera Schs. is much smaller than disjuncta , black, in the basal half of the forewing orange, 
only the base itself and a short streak at the base of the costa black; the basal half of the costal margin likewise 
orange. Costa Rica. 
4. Genus: Heliactiniclia Hmps. 
Proboscis capable of function. Palpi quite short, porrect, antennae of the $ with rather long comb- 
teeth. Body much more slender than in Brycea , the hindwings rather large. The species belonging hereto differ 
greatly from each other, but they are all marked yellow, or entirely yellow. They are apparently confined 
to South America and not common. 
H. chiguinda Drc. (38 f). Hitherto only Gcf are known. They are blackish-brown; forewing with a 
yellow basal ray and a yellow transverse stripe, hindwing with a yellow wedge-shaped spot in the disc and a 
narrow streak before the proximal margin. Ecuador. 
H. bhnaeulata Drc. approximates chiguinda (38 f). Head, antennae, palpi, tegulae, thorax, and legs 
black. Collar yellow; abdominal sides yellow. Forewings lighter brown; a yellowish-white postcellular band 
extends from the costal margin to the anal angle, being broadest at the costa. Hindwings orange-yellow, apex 
and anal angle broad black. South East Brazil. 
H. flavivena Dogn ., with an expanse of 31 mm, has brown palpi with yellow bristles at the base. 
Thorax brown, likewise intermixed with yellow hair; abdomen yellow, with a black dorsal stripe. Forewings 
above light grey, at the base a yellow spot. Veins well marked, pale yellow; fringes yellow. Hindwings yellow. 
From Cali in Colombia. 
H. sitia Schs. resembles flavivena ; body yellow, with a black dorsal stripe. Forewings olive-grey, with 
yellowish veins; from the costal margin across the cell-end to the proximal margin, near the anal-angle a light 
shade, on it round the cell-end some small yellow scales; hindwings orange. <$ 38, $ 40 mm. From the Sixola 
River in Costa Rica. 
H. coerulescens Hmps. (38 f). Black, with a blue lustre, both wings are traversed by a golden-yellow 
median band, from which a large obtuse ray emerges towards the middle of the margin on both wings. Colombia. 
H. austriaca sp. nov. (38 f) resembles coerulescens , but on the forewing there is a large, yellow, irregular 
discal spot; hindwings quite black, without any yellow. The upper surface has a less bright blue lustre than 
the under surface. Ecuador. 
H. nigrilinea Wkr. (38 f) is larger, yolk-coloured, with a blackish brown costa of the forewing. 
South Brazil. 
5. Genus: Pterootles Btlr. 
One orange-yellow species forms this genus. The 2nd subcostal vein of the forewing anastomoses with 
the footstalk of the 2nd and 3rd, so that an areola is produced, which is absent in the preceding genus, but 
occurs again in the following Haploa. The structure is slender, the hindwings much smaller than in Heliactinidia. 
Proboscis strong, palpi bent up before the forehead, not lowered as in Virhia or Eiibaphe. 
P. longipennis Wkr. (38 f) from Mexico is unicolorously orange-yellow. Costal margin, apex and 
distal margin finely bordered with black. 
6. Genus: Aiitiotriclia Fldr. 
Forewing without an accessory cell, the discocellulars of both wings longer. Palpi quite short, porrect. 
In the hindwing the lower margin of the cell is much longer than the upper; proboscis present. 
A. integra Wkr. (= vexata Fldr.) (38 f). Unicolorously yellow, but lighter than the preceding, all 
the wings finely bordered with black. Colombia. 
A. marcescens Fldr. (42 i). Rothschild places this butterfly here, for which the genus Agaposoma 
was established by Felder, and which probably scarcely belongs here. There seem only few specimens to be 
known, which are at present not accessible to me. As much as we can see from Felder’s figure, which we 
copy, the venation fits better to the group oft he genus Pachydota. Kirby places the species to the Hypsinae (not 
represented in America). Hampson does not mention it in his Arctiinae. The rather large butterfly has an 
orange abdomen banded black, brown forewings and yellow hindwings with a black preapical spot and a 
hook-like stripe before the proximal margin. Ecuador.
