exhibits the marking of Dalaca, from the assa-group perhaps. Very light brownish cinnamon with light brownish 
olive bands and spots. Body and hindwing darker cinnamon, antennae short. — The parcel in which this lepi- 
dopteron was sent to me contained also a little bottle with the very abundantly deposited eggs. r l he egg is 
globular, glossy black and has a diameter of hardly y 2 mm - 
D. subfervens Btlr. $ variable, forewing golden light red-brown, with a slight reddish lustre, smoke- subfervens. 
brown markings, brownish ochreous with subsequent red-brown markings. Costa with a series of mostly rounded 
spots partly pupilled black; a broad very irregular band from the base along the median vein to the centre of 
the disc, filling the basal half of the median area and uniting, towards the other end, with a series of obliquely 
confluent patches extending in a decreasing series to the costa. This band shows black spots and lines; its basally 
extended part projects from the inner margin in a rather large oblique black patch above which the margin 
is golden, light red-brown, coherent with a similarly coloured distal margin. Submarginal and marginal rows 
of black dots. Fringe pale red-brown. Hindwing pale dark smoky grey, fringe light red-brown. Thorax dark 
brown, antennae light red-brown, abdomen pale greyish brown. Under surface grey, body beneath dingy white, 
legs somewhat reddish. 32—38 mm. The $ has more red forewings with less distinct markings, and more bluish 
grey hind wings. Thorax redder than in the <$. Abdomen darker. 47 mm. Chile (Las Zonas), February. 
D. pallens Blch. is closely allied to subfervens. Forewing greyish brown marbled with white spots on pattens.

D. marmorata Btlr. Forewing creamy, divided by intersecting greyish brown bands into spots and pieces marmorata. 
on which there are black markings. Hindwing grey, 2 black subapical spots; fringe creamy; thorax blackish 
brown, paler in the middle; head and antennae smoky brown, abdomen greyish brown. Basal segments and 
markings whitish. Wings beneath greyish brown, silky, basal part and fringe pale blackish brown; ventrum

D. versosa Blch. (=■ nigricornis Wkr.). turtoise-coloured, forewing brown with white partly confluent venosa. 
stripes. Hindwing somewhat darker, base paler, fringe white. Length of body: 8—9 mm; length of wings: 
23 mm. Chile. 
D. hemileuca Btlr. is well discernible by the bipartition of the colour on the forewing. forewing silky hemileuca. 
brown, almost black at the costal margin as far as 2 / 5 of its length, a large spot occupying almost the whole 
inner margin the same. The rest of the wing very light silky brown. A small light red-brown spot in the apical 
third. Below it 2 oblique silky grey spots, and from the lowest 3 similar ones upward to the apex. An oblique 
whitish brown stripe divides the exterior end of the dark spot at the inner margin. Hindwing greyish brown, 
paler at the base. The $ is larger and paler. The light and dark areas less contrasting. 30—41 mm. Chile. 
D. fusca Mab. (185 b). 27 mm. Taken by Dr. Hyades at the Orange Bay, Chile. Blackish brown; fore- jusca. 
wing intensely brown, reddish at the base, a grey macula in the middle with two black dots, and a broad ante- 
marginal band. One <$. — A probably closely allied species I received from Chile. I found it nowhere described. 
30—40 mm. Brown, marking very variable, forewing with a black basal ray at the inner margin and 2 light, 
dark-edged, more or less visible maculae. The distinctly marked specimens show a Noctuid-like habitus of the 
forewing. According to 8 specimens. Valdivia. I denominate the species: noctuides sp. n. (99 e). noctuides. 
D. mutmmea Schs. Very light grey with a paler exterior and submarginal band, the latter composed of mummea. 
coherent square spots. 40 mm. Petropolis (Brazil).
