Ch. major Gn. (= maja Wkr.) (19 d) has dull red-brown forewings more or less dusted with grey 
or purple, with double transverse lines, the posterior line dentate with black dots behind it; between the grey- 
ringed maculae a shortened median shade, the reniform macula with or without 4 white dots at the angles; 
the light undulate line subapically with one or two small black spots and with or without small grey and black 
sagittae on the proximal side. Hindwing blackish-brown with a yellowish tint. Brazil to Paraguay and Argentina. 
Ch. crenilinea Hmps. (19 c). Forewing purple red, at the costal margin dark brown, subbasally and 
instead of the anterior transverse line black dots, the posterior line dentate with black dots on the veins behind 
it; instead of the ring-macula a white dot, instead of the reniform macula in each angle of the cell one small 
dark spot, in the lower angle a dark small spot with 2 fine white dots distally; the undulate line consists of 
small blackish spots between the veins and a hazy larger spot above and below the middle radial branch. Hind¬ 
wing blackish-brown, towards the base lighter with purple red fringes. Expanse of wings: 48 mm. South- 
Eastern Peru. 
Ch. rectilinea Hmps. (19 d). Forewing dull reddish-brown, thickly strewn with ochreous-brown, 
with ochreous-yellowish transverse lines, with black dots behind the distal line, behind it tinted purple; the 
upper maculae are finely encircled with ochreous, the reniform macula also distally filled up with ochreous; 
before the yellowish undulate line black dots, the marginal area behind it thickly dusted with ochreous. Hind¬ 
wing blackish-brown, fringes reddish. Argentina. 
Ch. albimargo Gn. (19 d). Forewing grey, dusted with red-brown and strewn with dark brown, with a 
white proximal margin, the anterior transverse line proximally bordered with whitish, a double posterior trans¬ 
verse line filled up with grey, with dark dots on the veins behind it, and light-striped veins in the marginal 
area; maculae large, in white rings, with a dark median line between them; the yellowish undulate line is proxi¬ 
mally bordered with red-brown. Hindwing blackish-brown with yellowish-white fringes. Brazil. 
Ch. erythrias Drc. (19 d). Forewing dark red-brown with a grey spot at the cell-end; distal margin 
black with a light marginal line. Hindwing dark brown, towards the base lighter. Expanse of wings: 38 mm. 
South-Eastern Peru, Bolivia. —- inversa form. nov. (19 b) has on the contrary light brownish forewings with 
a blackish reniform macula, fine darker double transverse lines, the posterior line composed of dots on the 
veins. 
Ch. ochrias Jones has light ochreous-brownish forewings with indistinct double transverse lines 
with lighter fillings, the distal part of the posterior line only composed of dots on the veins; a Y-shaped 
median band contains the reniform macula; before the undulate subterminal line a darker nebulous band 
growing lighter towards the posterior transverse line. Hindwing brown. Expanse of wings: 41 mm. Brazil: 
Castro (Parana). 
Ch. nictitans Jones. Forewing lustrous violettish-brown with double transverse bands with lighter 
fillings, being subcostally acutely angled, behind the posterior band black dots on the veins. Undulate line 
proximally ochreous-yellow, distally black, with a blackish-brown spot on the discal fold; discal area darker; 
maculae yellowish-white, dusted with brown, the lower end of the reniform macida pupilled brown, both con¬ 
nected by a bent, fine, yellowish-white submedian line. Fringes undulate. Hindwing dark brown. Expanse 
of wings: 42 mm. Sao Paulo. 
Ch. noctuiformis Hmps. (Gn. i. 1.) (19 e) is the largest species, light purple brown, strewn darker 
with double transverse lines, the posterior line dentate; maculae encircled with yellowish-white, the narrow 
reniform macula oblique, with a black dot in the lower end; subterminal area as far as the dark undulate line 
darkened, the latter with a dark spot subapically. Hindwing brownish-grey with yellowish fringes. Brazil. 
Ch. assodata sp. n. (19 e) is smaller and with narrower wings than noctuiformis, more ochreous- 
brown, in the basal half and at the costal margin olive-ochreous with rather indistinct double transverse lines; 
the maculae of the ground-colour, very finely encircled with ochreous-yellow, the reniform macula without 
a dark pupil, the subterminal area not darkened, with a circular black spot above the middle radial branch; 
in noctuiformis the black, much smaller spot is situate above the upper radial. According to 1 G from Sta. Cruz 
(South Brazil); type in the collection of the Senckenberg Museum (Coll. Seitz). 
Ch. satellitioides Gn. (19 e). Forewing purple grey with 3 dark brown transverse bands and 2 fine 
lines between them; no maculae except 2 quadrangular yellowish-white spots representing the reniform macula; 
behind the undulate line a row of grey dots before the margin. Fringes like in the preceding rather strongly 
dentate. Hind wing reddish-brown. Brazil (Novo Friburgo). 
Ch. dulcinea Bllr. (19 e) is a much smaller species with undentate fringes. Forewing light red-brown, 
strewn with purple, with double transverse lines filled up with grey, behind the posterior line with black and 
white dots on the veins; the maculae are in yellowish or whitish rings, the reniform macula below pupilled 
blackish, between both with a faded median line; the ochreous-yellowish undulate line is proximally bordered 
with red-brown. Hindwing blackish-brown with reddish fringes. From Chile.
