and reaching the inner margin of the posterior wings near the 
middle. Beyond this isa less curved band commencing on the 
costa beyond the middle and reaching nearly to the anal angle, 
followed by a space rather paler than the rest of the wings. Be- 
yond the middle are four black dots, the first and fourth largest, 
the latter pupiled with white. Faint indications of the bands 
above are visible below. 
Head rufous ; antennee brown, darker towards the apex ; palpi

Genus Draprema, Boisd. 
The genus Diadema of Boisduval is a most interesting one, 
from the resemblance which many of the species bear to those of 
other families. In general we find a Papilio and either an Eu- 
plea, Danaus or Acrea always of the same country, which they 
much resemble in form, colour and character of the markings,— 
in some species so close as to have caused some confusion as to 
their identity with the older figures. In D. Bolina it is only the 
female which offers this resemblance to species of other groups, 
and as yet there has not been found representatives for two or 
three species, but probably some day these will occur.

Anterior wings semitransparent, fuscescent, the ternal mar- 
gin tinged with red: in the discoidal cell are four rounded black 
spots, three placed in a triangle towards the base, one near the 
extremity, a similar spot on the disco-cellular nervule, one on the 
first median nervule, three at the base between the median and 
radial nervure, one on the radial a little beyond the middle ; ner- 
vules fuscous, between them a series of fuscous strize, on the fourth 
of which is a rounded whitish spot. Posterior wings rufous, 
paler towards the inner margin, the base itself black ; the dis- 
coidal cell with three rounded black spots, the two nearest the 
base almost confluent; around the cell are six black spots, of 
which the fourth is very small, the fifth on the disco-cellular ner- 
vure. These are followed by two spots near the inner margin ; 
the outer margin has a rather broad black border, undulated in- 
ternally, marked with seven more or less lunulated red spots.
