on the disk of these wings. LExpanse of wings 89 millim.

As Mr. Moore has figured P. discrepans in his revision of 
the Ophideride, there will be no difficulty in identifying the 
species described above. 
55. Ctypansa bocanidia, sp. n. 
Lilacine grey ; the wings traversed by two more or less 
diffused chocolate-brown stripes, the first at about the basal 
third oblique and regular, the second irregularly angulated, 
bounded externally by a series of white points, and crossing 
the centre of the disk ; fringes, especially of the male, bluish 
grey and spotted with chocolate ; primaries with a black spot 
at the end of the cell. Under surface dark smoky grey, the 
wings crossed by three equidistant dusky stripes, the outer- 
most of which is bounded externally by a series of creamy- 
white spots. Hxpanse of wings 41 millim. 
Duke-of- York Island. 
The female is a little darker and more purplish than the 
male, and the stripes on the upper surface of its wings are 
darker and more diffused. 
56. Heleona tyrianthina, sp. n. 
d. Allied to H. mars of Boisduval (?=fenestrata, Swains.), 
shining blue-black ; primaries with a trifid bluish-white hya- 
lime band before the middle, a small spot at the end of the 
cell; three spots in a subapical series and an oblong spot near 
the external angle upon the first median interspace: secon- 
daries with a broad belt of semitransparent creamy white 
before the middle ; basal half of costal area lilacine grey; an 
irregular discal series of bright orange spots: palpi, borders 
of collar, and posterior margins of abdominal segments bright 
orange ; abdomen more purplish, and the thorax more green- 
ish than the wings ; anterior half of pectus and posterior half 
of venter bright cadmium-yellow: legs below greyish, above 
dark purplish ; posterior tibiz with large sandy-brown tufts ; 
base of abdomen pale purplish brown, with a whitish posterior 
border. Expanse of wings 92 millim. 
Duke-of- Y ork Island. 
A pair of this beautiful species, from New Ireland, was 
presented to the collection by Messrs. Salvin and Godman. 
They both have paler bodies (ash-grey with yellow bands)
