EUCEREUM. By Dr. M, Dkaudt. 
merula. E. merula Dogn. (24 h). Head and thorax are bluish-grey, with blackish-brown spots and stripes. 
The abdomen is bluish-black, above at the base with brownish hair, the penultimate segment brown. Fore- 
wings bluish-grey with black veins, a faded black discal shade and spot at the cell-end; also an antemargi- 
nal, dark shade. Hindwings hyaline, the margin being irregularly clouded grey and black. Expanse of wings: 
24 mm. Ecuador. 
fanum. E. fa Slum Druce. Anterior body black, head and base of collar spotted white; abdomen bluish- 
black with a series of white lateral spots, chest yellow, the black legs underneath white. Forewings black 
with a large grey spot round the cell-end, the costal and proximal margin striped grey. Hindwings black, 
in the disc whitish diaphanous with black veins. Expanse of wings: 52 mm. Venezuela. It seems to be 
doubtful whether this peculiar animal, being known to me only from the description, belongs to the genus. 
maricum. E. maricum Cr. (= grylloides Wkr., thalassica Fldr., virescens Moscld.) (24 i) has a blackish-brown 
body; in the neck two red dots; the thorax is marked orange-yellow. The forewings are bluish-white, veins 
and spots at the proximal margin and costa yellow, with numerous blackish-brown spots, which are more 
like streaks in the inner-marginal area and at the base; in the middle of the cell an isolated, small, round 
amazoni- spot. The hindwings are bluish-white with a very broad, black border. Brazil, Bolivia. -— subsp. amazc- 
cuni. n j cuiri JRothsch. has the spots of the forewings more blurred, the postdiscal band being of a more yellow' tinge, 
and the margin of the hindwing not. so deep black and more irregularly defined. From the Amazon. -—- 
posicoe- postcoeruleum Rothsch. (24 i) differs from amazonicum by the very narrow black border of the hindwing, 
rulcum. only an apical spot being more extensively black. Distributed from British Guiana through Venezuela as 
far as Bolivia. 
appunc- E. appunctatum Dogn. (24 i) is similarly marked as casca and albinotum, but the abdomen is above 
tatum. carmine, the 2 first rings brown. Head and thorax likewise blackish-brown, in the neck a’ carmine ring. 
The blackish-brown forewings are veined light yellowish. Belov/ the base of the cell is a small, white spot, 
in the cell-end a square, behind the cell a large, reniform, white spot between the 2nd subcostal vein and 
the middle radial. An antemarginal, indistinct, curved row of whitish dots. The hindwings are blackish- 
brown, towards the base whitish. Expanse of wings: 34 mm. Ecuador (Loja). 
rosa. E. rosa Wkr. (24 h) has dark brown forewings with somewhat lighter yellowish veins with pale 
brownish markings, 2 antemedian small spots, a square one in the ceil, an irregular, distal transverse line 
and an indistinct marginal dentate line. Hindwings blackish-grey. 2 spots on the vertex, and the neck 
are carmine. Thorax and first abdominal ring dark brown. Abdomen otherwise carmine, with a dark broAvn 
lateral line. Venter yellow. Mexico, Honduras, Parana. 
rosaclora. E. rosadora Dyar (24 h) from Mexico is smaller, darker and much more indistinctly marked. — 
xanthodora. In xanthodora Dyar the red colour turns yellow. 
rosina. E. rosina Wkr. (= rhodophila Druce ) (24 i). Plead and thorax light grey, on the vertex a blackish 
spot, neck carmine, collar with a black spot, shoulder-covers margined with black. Abdomen light carmine, 
at the anus whitish, laterally more or less developed black spots. Forewings whitish, mixed with grey; 
the veins in the discal area yellowish. Blackish basal spots bordered with yellow, a series of 6 antemedian 
spots, the one above vein 1 longish, connected with the proximal margin by a yellow line running towards 
the base, median and submarginal, irregular rows of spots, as well as some marginal streak-shaped spots. 
imprima- Hindwings diaphanous white, at the border narrowly dark. Mexico, Venezuela, Trinidad, Brazil. -— f. im- 
ium - primatum Wkr. is distinguished by the yellow colour being greatly increased round the spots, so that the 
basal spots turn almost entirely yellow; the dark border of the hindwings is confined. 
hoegei. E„ hoegei Druce (24 i) has whitish forewings with quite pale, reddish-grey spots and transverse bands; 
on the transverse vein there is a somewhat larger spot, and below it a streak more towards the base, cros¬ 
sing vein 2. The anterior body is whitish, with faint brownish markings, the neck and abdomen pale car- 
lutescens. mine rosy, the latter with a white anal end. The red colour may be changed into yellow: lutescens form, 
nov. ■ — From Mexico.

black spots. Abdomen light carmine, at the end blackish-brown, the anal tuft whitish; black lateral spots; 
venter yellowish white. Forewing whitish-grey, in the basal half mixed with a darker colour. Some dark 
basal and 5 antemedian spots are bordered light; a straight median and an irregular distal transverse row 
of darker spots touch each other in the disc by the large spots near the cell-end; a submarginal row of smaller 
spots is parallel to the border; at the base of the fringes there is another row of blackish marginal dots. 
Hindwings brownish-grey. -—- Mexico, Guatemala, Panama, Amazon, Espiritu Santo.
