J Fuscous-brown J ivith a very slight purplish gloss. Fore-wing : a 
faint indication of a darker spot at end of cell. Under side. — Much 
paler. Fore-iuing : a roiu of very brilliant steely dots along costa, 
larger and dark- edged beyond middle ; on hind-margin a row of five 
larger steely spots, inwardly black-edged, between apex and first 
median nervule ; spot at end of cell large, ill-defined, dark-brown ; 
a little beyond it a similar larger, sub-quadrate mark on discoidal 
nervules, usually marked with some steely scales ; costa near base 
and hind-marginal edge tinged with golden-ochreous. Uincl-wing : a 
central straight transverse band of glossy ochrey-brown, of unequal 
width, marked on both its edges with steely points (of which there 
are also a few in middle of stripe) from costa beyond to inner margin 
before middle : a good-sized similarly hued spot in cell and two others 
on costa before middle ; beyond middle a row of five contiguous, pale- 
edged, steely-centred ochrey spots, obsolete above second subcostal 
nervule ; hind-marginal spots as in fore- wing, but more conspicuous 
and occupying the whole length — the three next anal angle larger 
than the rest, geminate, with black edges; inner marginal and discal 
region thickly irrorated with violaceous-white scales. Cilia greyish. 
$ Bases loith bluish-grey hairs and scales; in each wing a discal 
space of white outwardly ill-dcfimd. Cilia paler, nearly white in 
hind-wing, inconspicuously interrupted with fuscous. Under side. — 
Markings similar to J, but luhite occupies the ground, except on hind- 
margins and on costa of fore- wing. Fore-wing: discal and cellular 
spots very conspicuous, the latter confluent with a brownish space on 
median nervure from base. Hind-iving : markings very conspicuous 
on white ground. 
Mr. A. G. Butler first pointed out {Cat. Fab. Diurn. Lep. Brit. Mus., 1869, 
p. 175) the close alliance between, if not the identity of, the Delegorguei oi 
Boisduval and the Bibulus of Fabricius, — he having found both sexes well 
figured in Jones's Icones, quoted by Fabricius, op. cit. The description of 
Bibulus by this author is so inaccurate that no one without the aid of Jones's 
figure could have assigned it to Delegorguei $ ; but that of Ladies, Fab., ap- 
plies thoroughly to Delegorguei 9 • 
Both sexes vary much in size ; but as regards markings and colouring, while 
the $ seems remarkably constant, the 9 exhibits much variation in the discal 
white on the upper side of both wings, ranging from a mere dull-whitish mark
