D. chiriquensis sp. n. (99 b). The $ is much larger (75—85 mm), body as long as 39 mm. Darker; fore¬ 
wing more brown; the $ with chocolate foreAvings, hindwings dull dark claret. From the Chiriqui Volcano. 
D. indicata Strd. likewise belongs to this group. Separated from assa (99 c) by the following: forewing 
with rather hard-marked black lighter-edged small roundish and oval spots, about 8 of which form an oblique 
row from shortly without the middle of the inner margin to the costal margin 4 mm from the apex, while 7 
spots are rather regularly arranged along the costal margin. Single spots in the centre of the dorsal area, an 
antemedian oblique band of small spots, and several dense irregularly arranged small spots in the basal half. 
3 silvery spots near vein 6, the black longitudinal stripe at the base absent, hindwing somewhat darker than 
in assa. 47 mm. Length of body 26 mm. Macas (Ecuador). 
D. serta Schs. Body reddish brown, somewhat grey at the inner and distal margins; linear transverse 
stripes pierced by the veins cover the wings with a great number of grey lunules shaded outward, being most 
numerous in the distal third of the wing. Hindwing red-brown. J. Mexico (Jalapa). 
D. usaque *) Pf. (99 f). 40 mm. Smaller and darker than assa (99 c), more red-brown; foreAving with 
a tiny golden dot in the basal part; a golden comma-like mark in the centre of the A\dng between the bands, 
hindwing dark red-brown, abdomen and base of hindwing bright red. I obtained this species besides others 
through A. H. Fassl from Colombia (Muzo, 700 m). 
D. sladeni Hmps. Antennae of very little dentate, the dents symmetrical; head, thorax and abdomen 
fox-coloured, mixed with brown. Forewing fox-coloured with numerous pale stripes and reticular markings; 
costal area, median area beloAv the cell and the space between veins 3 and 6 filled with dark brown. Pale stripes 
form an oblique irregularly curved line from the costa before the middle as far as behind the centre of the inner 
margin, where it meets an oblique slightly bent line from the costa before the apex. A curved white marking 
composed of 2 small spots at the origin of veins 5 and 6. HindAving red-brown, costa spotted ochreous. 34 mm. 
Chapadu (Central Brazil, A. Roberts). 
D. terea Schs. Forewing dull faAA r n-coloured with a slight reddish tinge. A small dark stripe at the cell- 
end, behind which there is an interrupted dark transverse line, besides with numerous short pale, distally brown 
transverse stripes. Hindwing very light red. 42 mm. Mexico: Paso San Juan. — A similar much larger form 
(80 mm) of a paler colouring and marking I got from the Chiriqui; I denominate it: muysca form. nov. (99 f). 
D. coscinophora sp. n. (100 b). Size about 45 mm. Forewing dull loamy yellow, with a darker sieve-like 
marking. HindAving and abdomen very didl yellowish red. Beneath as above, still duller, without any marking. 
From Nivac (Matto Grosso). 
D. obliquestrigata Strd.. according to the figure, seems to be allied to olivescens, but lighter, more reddish 
brown, most of the interior area light greyish, hindwing more ochreous, feebly red towards the base. Expanse 
of wings: 52 mm. Length of body: 27—28 mm. From Peru and Ecuador (Upper Madre de Dios and Macas). 
D. olivescens Pf. (99 e). Size of assa (99 c). Forewing olive brown, watered silvery grey at the base at 
the inner margin and in the distal area. 3 rather parallel steep transverse lines on the costa, the last very much 
bent outward and shortened. Abdomen and hindwing coffee-brown. Received from A. H. Fassl, from Sosomoco 
(Colombia), 800 m. 1 specimen, 52 mm. 
D. trilinearides Pf. (99 c) resembles olivescens. but the thorax and forewing bright red-brown, the stripes 
more oblique, the last not bent and shortened. Hindwing and abdomen light cinnamon red. 47 mm. Sosomoco 
(Colombia). From A. H. Fassl. 1 specimen. 
D. vibicata Pf. (99 c) resembles trilinearides, but the thorax and forewing pale yelloAvish grey, the 3 trans¬ 
verse lines distinctly defined, like raised streaks; abdomen and hindwing very pale reddish ochreous. 38 — 48 mm. 
Sosomoco, 800 m. By A. H. Fassl. 
D. michaeli Pf. (99 d) resembles vibicata in its colouring, but much paler; lines indistinct. More than 
twice as large. Thorax and forewing very pale yellowish grey, hindwing and abdomen very pale reddish in the 
S, tinged with yelloAvish in the 2 specimens from the Chanchamavo (1000 m), 1 from the Upper Amazons, 
received from Otto Michael. expanse 78 mm, length of body 37 mm. expanse 96 mm, length of body 
48 mm. , 
D. cuprifera Pf. (99 f). 88 mm. Robust; body relatively short, head, thorax, legs and foreAving copper 
red, the lighter transverse bands partly filled with blackish streaks. Hindwing dull copper brown, somewhat 
diaphanous, abdomen dull brown; under surface brown, costa of forewing spotted light. Peru (Coll. Staudinger). 
D. manoa **) Pf. (99 d). A $ of this new prominent species which I place to Dalaca for the present 
(others range it among Phassus) I received from Fassl who captured it in February 1911 near Villavicencio in 
Eastern Colombia at an altitude of 450 m. Expanse of wings: 112 mm. Length of body: 62 mm. The forewing
