consider the specimens with these antennz females. ‘They are now for the first time 
noticed ; and I know no other instance amongst Lepidopterous insects in which pectina- 
tions are developed in the female antenne whilst those of the male are simple. On 
the underside the wings are brown, buff at the base, the fore wings without basal 
markings and with a central fascia shaped as on the upperside, white, very slightly 
tinged with luteous; the apical margin with a sharply marked pale buff edge, slightly 
scalloped within and finely irrorated with brown scales; the costa indistinctly marked 
with four dark spots beyond the fascia: the hind wings have a central, strongly 
scalloped, narrow, pale buff fascia, very oblique, preceded and followed by a slender 
black waved line, the veins beyond the fascia being dark brown, dotted with minute 
buff marks ; between the anal angle and the tail, and between the tail and the outer 
angle, the margin of the hind wings is buff, irrorated with brown scales.

C. alis fusco-nigris, fascia media continua anticarum recta alba, posticarum curvata 
albo-cerulea micante; subtus pallidioribus fascia communi angustiore alba lilacino 
micante (fem.). Expans. alar. antic. unc. 2, lin. 2. 
Antenne in figura Hopfferi parum serrate videntur. 
Coronis hyphasis, Hopffer, Lep. nov. pl. Ixxxvii. fig. 2, 3. 
This species is distinguished by the middle band of the fore wings being more trans- 
verse, reaching considerably within the posterior angle of the wings, to which it is 
united by a short marginal extension, so that it is much more continuous with the band 
of the hind wings than in any of the other blue-banded species.

Sp. 5 (88). CoronipIA HYSUDRUS. 
C. alis fusco-nigris, fascia media non continua anticarum obliqua alba, posticarum 
subcuryata, cyaneo micante ; subtus fuscis, anticis fascia lilacino-alba, posticis testaceo 
irroratis (mas. et fem.). _Expans. alar. antic. lin. 24, 25. 
Coronis hysudrus, Hopfter, Lep. nov. pl. Ixxxvii. figs. 4, 5. 
This species is closely allied to C. boreada, from which it differs in the form of the 
pale band of the hind wings, and in the structure of the antenne. Hopffer 
figures a female, but states that specimens of both sexes are in the Berlin Museum. 
It is therefore evident that, had the antenne in either or both sexes been pectinated, 
he would have represented or described them so.
