under side is yellowish brown, the spots are reproduced, but 

 that next the apex of the wing only as a minute dot. The 

 posterior wings show three minute round black dots in a line, 

 and encircled by black, a small round silver-white spot nearer 

 the base. The upper part of the body is of the same tint as 

 the wings, but rather darker ; the hairs and scales on the 

 underside pale to orange yellow in various shades. It flies in 

 'NoYemhev. 



Hesperilla atralba, spec. nov. 

 PI. II., fig. 5. 

 This species, which occurs with the foregoing, is considerably 

 smaller than it, and is almost black. Both pairs of wings are 

 edged with a fine white line and fringe, separated by seven 

 black spots in the first pair ; the base of same is tinged 

 brown ; three rather large angular white spots, lightly tinged 

 with a yellowish shade, are arranged in a semi-circular order, 

 and form almost a band ; between these and the apex are two 

 similar ones, touching each other by one corner only. Near 

 the middle of the posterior wings is a rather large oval 

 greenish-yellow spot, and the part of the wings from it to the 

 base is tinged lightly with the same hue. The underside of 

 the anterior wings is also nearly black, the spots reproduced, 

 an orange streak at the base along upper edge, the apex of 

 wings grey, with indistinct darker marks. The underside of 

 posterior wings is uniformly grey, with several transverse rows 

 of faintly darker, irregular, ring-like marks. The upper part 

 of the body is black, the lower grey. It flies low over the 

 ground in grassy open places in the bush in March, and sips 

 the juice of Dampiera rosmarinifolia and other low plants. 

 The name is suggested by the coloration of the wings. 



Hesperilla lutea, spec. nov. 

 PI. II., fig. 6. 

 This is a small butterfly, with an expanse of wing of 1^ 

 inches. The prevailing colour of its upper side is blackish- 

 brown ; the narrow fringe is of dirty grey ; the body 

 black ; the anterior wings show five small yellow spots, four of 

 which are in a line nearly parallel with the margin, the fifth 

 a little within near the upper edge ; an indistinct large yellow 

 spot near the middle marks the posterior pair. TJiiderside of 

 anterior wings blackish ; the spots reproduced, except that 

 next the apex ; edge and apex dark yellow. The latter colour 

 also tints the posterior wings, which have a small silver-white 

 spot near the centre, surrounded by a fine black ring. The 

 underside of the body is whitish-yellow. The figure is that of 

 a male. It was captured in November at Ardrossan.
