It is more than probable that what we at present call 
Idalus admirabilis 1s composed of a conglomeration of 
several species; but, without the examination of the geni- 
talia of a large series of specimens from a variety of localities, 
this can only be surmised. y 
There are individuals with and without the dark spot 
above vein 5, others with deep rose hind wings, some with 
white hind wings, ete. 
The ? in the present series has white hind wings, no spot 
above vein 5, and an almost straight median band, while the 
3 & all have the spot, have hind wings of varying shades of 
rose, and a strongly-curved median band.

Empusa daga, Dognin, Le Nat. 1891, p. 125 (Zumba). 
All the three Beeps are of the typical form with yellow 
abdomen. 
Formerly I sank the red-abdomened form dares, Druce, 
to the rank of an aberration, in view of the series of 
specimens at Tring from Las Quignas, Venezuela, consisting 
of individuals with brick-red abdomen as well as yellow. 
Apparently, however, specimens with yellow abdomen do 
not occur in Costa Rica and Ecuador, nor do individuals 
with deep crimson abdomen occur in Eastern 8. America. 
Therefore, either dares must be treated as a subspecies of 
daga or a8 a good species ; only the examination of the 
genitalia can decide which.

3. Closely allied to melanopasta, Dogn., but differs in the 
shape of the claspers. Externally the apex of fore wing is 
more produced and the outer half of wing is less freckled ; 
the hind wing has the apex produced to a sharp point, and the
