$ Fuscous-broivn, with a very sl'ujht purplish gloss. Fore-iving : a 

 faint indication of a darker spot at end of cell. Under side. — Much 

 paler. Fore-iving : a row of very hrilliant steely dots along casta, 

 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-defiued, 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. Hincl-ioing : 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 with Uuish-grey hairs and sccdes ; in each wing a disced 

 space of white outwardly ill-defined. Cilia paler, nearly white in 

 hind-wing, inconspicuously interrupted with fuscous. Under side. — 

 Markings similar to ^, but vihite occupies the ground, except on hind- 

 margins and on costa of fore- wing. Foix-ivUuj : discal and cellular 

 spots very conspicuous, the latter confluent with a brownish space on 

 median nervure from base. Hind-toiny : markings very conspicuous 

 on white ground. 



Mr. A. G. Butler first pointed out [Ccd. Fab. Diurn. Lcp. Brit. Mus., 1869, 

 p. 175) the close alliance between, if not the identity of, the Delegorguei of 

 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 

 Bibuhis 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 Laches, Fab., ap- 

 plies thoroughly to Delegorguei $ . 



Both sexes vary much in size ; but as regards markings and colouring, while 

 the $ seems remarkably constant, the $ exhibits much variation in tlie discal 

 white on the upper side of both wings, ranging from a mere dull-whitish mark
