but these, althougli numerous, are so minute as scarcely to alter 

 the general black colour of the wing ; costa red for about half its 

 length, — this colour commences within a short distance of the base, 

 and extends beyond the middle ; at the basal angle of the hinder 

 margin is a reddish spot, and above this, between it and the costa, 

 are two very small spots of the same colour, — on the hinder mar- 

 gin also, and near its anal angle, is a cream-coloured blotch, 

 various both in size and shape ; hind wings bright orange, with a 

 broad black border, which ceases just before the anal angle; fore 

 wings (beneath) blackish-brown, with the costa red, and a yel- 

 lowish suffused blotch near the anal angle and extending thence 

 along the margin to the base ; hind wings reddish-orange, with a 

 central black lunule and a broad black border, this diminishes 

 towards the anal angle, before reaching which it ceases entirely, — 

 the extreme margin of the wing is paler, and the cilia again dark; 

 the under side of the head, thoracic segments and the coxae are 

 bright red ; femora reddish-black in front, tibiae blackish mingled 

 with red; fore and middle tarsi blackish, hind tarsi golden yellow; 

 fore tibiae unarmed, middle tibiae with two strong apical spines, 

 hind tibiae with four strong spines — two median, two apical ; ab- 

 domen (beneath) red, with a black vitta along the middle, and a 

 row of black dots along each side ; the three segments preceding 

 the anus are slightly dilated laterally, and each furnished with a 

 lateral tuft or brush somewhat as in Macroglossa. 



This species is certainly allied to others which Mr. Walker has 

 placed in his new genus Castillo, but is quite distinct from any he 

 has described. Setina irrorella and Gnophria rubicollls are its 

 nearest allies in the British Fauna. I have named it after my 

 friend Henry Doubleday, who is, nemine contradicente, the prince 

 of British Lepidopterists. Two specimens only were taken.
