 Pap. ilicis, Esp., an diversa species ?] In this species the palpi are 

 porrected, quite white on the inner side, but exteriorly only at the 

 base, the rest being black. The eyes are reddish- brown, and have a 

 white border. The antennae are black, ringed with white ; the club 

 reddish-brown beneath and at the tip. The head is quite black. 

 The thorax and abdomen often shade dorsally into brownish-black. 

 The pecten is bluish-white. The abdomen ventrally ashy-grey. 

 The upperside of the wings of a sooty colour, more deeply black 

 towards the hindmargin. The inner margin of the hindwings 

 is of the same tint, but rather paler. The cilia at the anal 

 angle of the hindwings consist of long black hairs, above which 

 is an ill-defined orange spot. Between the anal angle and the two 

 tails the margin is white, and, at the extreme tip, black. The under- 

 side of the wings is umber-brown, varied with a little reddish- 

 brown, and ashy-grey towards the hinder angle ; near the middle of 

 the forewings is a white transverse stripe, which at first inclines towards 

 the hind margin, but is afterwards curved upwards. The hind margin 

 of the hindwings, and the outer margin of the border, is white ; above 

 this runs a black line, which has another white line above it ; next to 

 the black anal angle stand two triangular spots, above which runs 

 an arched, dark orange-, almost red-lead coloured, transverse band,
