is a form from Venezuela, in which the wings are yellowish, the bands of the forewings ochreous-brown. 
H. fuligin osa Rothsch. (59 e) is at once recognizable by the dull brown colouring of the wings and fulUjinosa. 
the abdominal dorsum being black in the very dark yellowish-brown in the $. Beneath the body is orange, 
particularly the thorax. Mexico; the figure according to a specimen from Orizaba. 
H. atra Drc. (59 e). <$ deep sooty brown, $ somewhat lighter; from fuliginosa it differs by the absence atra. 
of the terminal band of the forewing, where also the subterminal band is reduced to spots at the costa, proximal 
margin and between the radial veins. The hindwings of the <$ bear a silky reflection in the sunshine. Abdomen 
blackish-brown, in the $ posteriorly yolk-coloured. Mexico and Guatemala, the figured specimens from Misantla. 
H. bricenoi Rothsch. (59 f). Larger than atra , easily recognizable by the bands in the apical third bricenoi. 
of the forewing in both sexes being completely reproduced by the marking of their borderes, though not by 
the colorial difference. Known only from Merida in Venezuela, from where also the figured specimen originates. 
H. masoni Schs. (59 g). A very fine species. The bright orange-red forewing shows a straight, greyish- 
yellow median band traversed by the thick black veins, a similar demi-band at the cell-end and the same colours 
in the basal and marginal areas; thorax fiery light red. Beneath the median band, cell-end spot and base of the 
forewing are marked black, the wings otherwise golden yellow. Known only from Mexico. -— The most peculiar 
distribution of the colours somewhat reminds us of Anaxita decorcita occurring in the same district. 
H. nero Wcym. (59 f) and the following species deviate very much from the genus by their colouring, 
and nero was also described as Amastus and only placed to Halisidota by Ha up son. Black, abdomen bright 
red, its base above black. From Joinville in Brazil. 
H. dukinfieldia Schs. (59 f) is like nero, but the abdomen black, only the base and anal part red, the 
head and collar being red, too. South Brazil (Sao Paulo, Castro).

H. notata Schs. (59 f). Blackish-brown, head and thorax with pale yellow and purple red markings; notata. 
abdomen posteriorly banded red, laterally spotted yellow. Forewing with pale yellow spots at the costal margin 
before, in and behind the middle, at the base of the proximal margin a faint stripe and a dot behind the middle. 
Hindwings whitish, margins and veins brownish, the brown at the border proximally irregularly defined; a 
triangular dark median spot. Size of the preceding. From Petropolis in the Organ Mountains, apparently 
an alpine insect and very rare. 
H. triphylla Drc. (59 f) and the following species neither look like a Halisidota. Their <$<$ are unknown, friphylia. 
triphylia has unicolorously dark brown wings with black veins. Head, thorax, and the posterior third of the 
abdomen are yolk-coloured. From the Chiriqui in Panama. 
H. humosa Dgh. (59 g) is slightly smaller than triphylia, the body quite similar in the colouring humosa. 
and structure, but the ground-colour of the unicolorous wings is more honey-yellow, for which reason the black 
veins are more prominent. The colouring and habitus somewhat recall Pachydota striata (55 i), Ischnocampa 
nigrivena (55 h) etc., but the ground-colour is greyer. Described from Loja. Ecuador; the figured specimen 
or ginates from the Upper Rio Negro (Colombia). 
forewings 
melaleuca. 
H. melaleuca Fldr. (59 g). White, neck and abdominal dorsum haired blackish-brown 
with pale ochreous-yellow embedments, at the costal margin and border brown spots marked black, of which 
a large one is distally blackish-brown, proximally yellowish, and encloses the white cell-end spot. Hindwing 
in the $ with a dark marginal band. Beneath similar as above. From the Quindiu Pass in the Central Cordilleras 
of Colombia. 
H. roseifasciata Drc. (59 g) and the following species also deviate considerably from the habitus of roseifascia- 
the other Halisidota, and both were also described as Automolis, though they would best form a special ia - 
genus. Forewings honey-coloured with a brownish border and a yellowish-pink layer on the margins 
and above the middle of the wing, which however, varies greatly in the different specimens. Still more charac¬ 
teristic than the wings is the body: anterior part of the head, collar and abdomen orange, thorax light honey- 
coloured, before the abdominal end 3 narrow black transverse bands. Peru and Bolivia. 
H. semibrunnea Drc. (59 g). All the wings blackish-brown at the margins, towards the base turning semibrun- 
at first red-brown, then honey-coloured. Head, collar and base of abdomen yellowish-red, thorax light yellow, nca - 
abdomen otherwise blackish-brown. Beneath the blackish-brown forewings are yellow towards the base, the 
apex being fiery red. Peru and Bolivia.
