$ White, with white -spotted Mack hind-margins. Fore-iving : costa 
with a linear black edging ; a black border on Mnd-margin, broad at 
apex, and narrowing to a point at anal angle, — its inner edge irregu- 
larly dentate and excavate ; a row of elongate white spots, from four 
to seven, in this border, lessening in size towards posterior angle, but 
not extending below first median nervule; a small sublinear black 
spot at extremity of discoidal cell. Kind-wing : a black border of 
moderate width on hind-margin, enclosing four rather large white 
spots, — of which rarely all are indistinct except the first ; in some 
specimens an irregular black transverse mark on costa before apex ; 
very rarely a thin blackish line at extremity of discoidal cell. Under 
SIDE. — Ifain markings like those of iqoper side, hut hind-marginal horders 
not so black, tinged ivith hroiun ; hind-vnng and marginal spots in fore- 
luing lemon-yellow or greyish-yellow^ — the former luith nenration almost 
always more or less clouded with hlack. Fore-iuing : base with a faint 
yellow tinge ; rarely a projection from costal black edging towards 
terminal disco-cellular spot ; hind-marginal spots larger and more 
sharply defined. Hind-wing : costa near base edged with chrome- 
yellow ; pre-apical costal black mark conspicuous ; a similar but dif- 
fused transverse black mark from about origin of second median 
nervule to about middle of submedian nervure, crossed by a longi- 
tudinal black streak from near base of median nervure to near anal 
angle ; hind-marginal border containing five spots of the ground-colour, 
the additional spot being close to anal angle ; near base, a short longi- 
tudinal chrome-yellow streak between median and submedian nervures, 
and another close to inner margin. Cilia black, interrupted with 
white between nervules. 
$ Varying from very pale whitish-yelloiu to pcde ochreous-ycllow ; 
hind-marginal Hack horders very hroad. Fore-iving : only two or three 
^ This reference was confirmed by a figure in the rough drawings of some of Wallengren's 
type specimens shown to me by Mr. W. F. Kirby, which, under the name of " Pinacopteryx 
Mesentina, Cram., var.," unquestionably represented a 6 Severina.
