spots in and below the cell, as well as 4 behind it, the two lower ones of which are placed more towards the 
margin. The hyaline hindwings are bordered with black, the anal-angular appendage being black. Hips and 
femora are ochreous-yellow, the legs black. Honduras; Costa Rica; Guiana; Para. 
H. tetragramma WJcr. (24 f) greatly resembles the preceding, and is distinguished by its brick-red 
chest, hips, femora and ventral side, and similarly spotted legs; the postdiscal hyaline spots exhibit blackish- 
brown dots. Amazon, 
H. assimilis Rothsch. greatly approximates tetragramma, and differs by the white ventral side and 
hips, by black, not orange-red veins on the forewings; the red colour of the abdomen is more brilliant carmine, 
in the basal half blackish-brown. Described from Peru. 
H. fulvipicta Kaye is distinguished by the very long, narrow shape of the wings. The head is black, 
behind the eyes spotted yellow; thorax and shoulder-covers blackish-brown. Abdomen black with a yellow 
basal spot; on the ventral side of the 3rd and 4th rings there are large, white sjjots. Forewings brownish with 
blackish-brown veins and transverse bands in the disc and at the apex, the basal area being black with a golden 
yellow spot. Hindwings hyaline with a broad black border. Expanse of wing: 35 mm. British-Guiana. 
H. elongata Rothsch. is unknown to me and may perhaps be synonymous with the preceding. The 
description is almost the same, but there are yet some yellow olive-grey spots mentioned on the thorax, and 
the posterior transverse band of the forewing is not denoted as apical, but as ,,postmedian“. Described from 
Venezuela. 
H. umbrimacula Schaus perhaps also belongs to the preceding. Body black, neck orange-red; on 
the metathorax there is a yellow spot; the forehips and a spot in the middle of the venter are white. The 
forewings are reddish olive-yellow with black veins; behind the middle, from the costal margin near to the 
proximal angle, there runs a broad, black nebulous stripe. The apex is broadly black, at the border with small 
spots of the darkened ground-colour in it; the costal base is spotted orange. The hindwings are white in the 
basal halves with black veins, distally black. Expanse of wings: 31 mm. French Guiana. 
H. dolens Schaus is black on the body, with a blue lustre on the shoulder-covers and abdomen, in 
the neck orange-haired; the forehips and the first ventral rings are yellow-reddish. The forewings are dull 
black with velvety black nebulous stripes before and in the middle, subapically and ante margin ally between 
the lower median and middle radial vein. Hindwings hyaline with a broad black margin. Expanse of wings: 
27 mm. Venezuela. 
H. postflavida Rothsch. is larger than dolens, and the 2 last abdominal rings are orange, not black. 
The forewings are comparatively somewhat broader, otherwise similarly coloured and marked. Venezuela. 
H. fumata Rothsch. This species has been established according to 2 much flown <$<$ from Ecuador 
and Peru. The body is sooty brownish-black, posteriorly with a blue lustre, on the collar carmine spots. The 
abdomen exhibits beneath two white bands. Forewings sooty brown, the hindwings sooty black, with 2 whitish 
longitudinal spots in the inner-marginal area. Length of forewings: 20 mm. 
H. fuliginosa Rothsch. is sooty black on the whole body above and underneath. The forewings are 
more grey, in the discal area between the veins thinly scaled. Hindwings hyaline with a black margin, being 
spottedly expanded at the proximal angle. Length of forewings: 16 mm. Peru. 
H. hecale Schaus is blackish-brown on the body, at the sides of the abdomen with metallic blue 
spots; 2 spots in the neck, and the hips are carmine. Forewings blackish-brown, in the disc in the cellular spaces 
thinly scaled, so that a hyaline, round, discal spot is produced. Hindwings hyaline, veins and margins broadly 
black. Expanse of wings: 42 mm. Peru. 
H. caeruleocephala Rothsch. Head lustrous blue; thorax metallic blue and yellowish. On the collar 
there is a carmine spot; the shoulder-covers are brown with lighter stripes. Abdomen of a brilliant metallic 
blue, on the 3 first rings above with long black hair. The forewings are of a wooden brown with dark brown 
veins, the hindwings black with a blue lustre, the cellular spaces in the disc diaphanous grey. Length of forewings: 
20 mm. Peru. 
H. emerentia Dogn. (24 g) resembles Delphyre tetilla, but the hyaline spots are differently distributed: 
the proximal one is situate below the middle of the cell; the head is all black, so is the neck, and not red, other¬ 
wise all is the same. Described from Ecuador (Loja), before me also from Colombia from the Upper Rio Negro, 
800 m. 
H. lemoulti Rothsch. greatly resembles Delphyre sufjusa, but the forewings are not marked so speckled. 
The body is blackish-brown; chest and base of hips, as well as 2 small spots in the neck are carmine-rosy. The 
abdomen is laterally spotted or striped bluish-green. The forewings are blackish-brown with an indistinct
