short, ending abruptly between 3rd and 2nd median ner- 
vules, -where it touches the second band ; between second 
and third bands a costal spot of the same colouring; ; a 
fourth band (not marked with silvery) occupies hind 
marg;in, and is traversed by an interrupted black line, 
which is inwardly bordered by Avhite sub-lunulate marks, 
both line and mai-ks being strongest at sub-median nervure, 
where they abruptly terminate. Hindivinfj : a basal and 
inner-marginal band, irregularly dentate on its edges, 
leaving a very narrow inner-marginal edging of white ; a 
second band, continuous of first band of forewing, crossing 
obliquely from costa about middle to a little distance before 
anal-angular lobe, where it narrows and coalesces Avith 
extremity of inner-marginal band ; a third band, running 
parallel to the second, is confluent at apex and about 
middle of hind margin, with a hind-marginal band similar 
to that of forewing, and near anal angle with the second 
band; no black traversing line in hind-marginal band, but 
the white markings more continuous than in forewing. 
$. IPithout purple gloss ; yelloio-oclireous markings in 
both icings ; basal region of wings irrorated Avith light-bluish 
scales. Foreunng : all the markings much more develojied 
than in $ ; the quadrate cellular marking more or less 
indistinctly produced into an oblique band, which, on sub- 
median nerviire Ijeyond middle, meets the extremity of the 
variable but iminterrupted sub-marginal stripe ; the much- 
enlarged V-shaped sub-costal marking beyond middle is 
prolonged to join sub-marginal stripe on 2nd median ner- 
vule (in two specimens it is confluent Avith the stripe). 
J lin dicing : inner-marginal region from base clothed Avith 
light-bluish hairs ; a narroAv sub-marginal yellow-ochreous 
stripe, commencing indistinctly about 1st sub-costal ner- 
vule, is joined betAveen 3rd and 2nd median nervules by 
an oblique, wider stripe of the same colour commencing on 
1st sub-costal nervule, about middle. Underside. — As 
in $ , but the transverse bands ]ialer, and inclining to an 
orange-ochreous tint ; Avhitish lunulate marks in hind- 
marginal border much enlarged and suff'iised. Foreicing : 
extreinity of third band does not meet the second band. 
Ilindwing: the inner-marginal band is externally more ir- 
regulai'ly dentate than in ^, a small portion at origin of 
1st median nerA'ule forming a separate spot. 
This AphncEus is distinguished from all its congeners 
by the silver g-wliite ground colour of the underside of the 
Avino-s. The arrangement of the bands of the underside
