Imago. — One 6* , four 9 • Body of the same color as in J., selene. Palpi of the shape of 

 those of A. selene; as well developed, being fully as large and long, projecting a little beyond the 

 lower edge of the front. The tongue (the maxilla? being separate) extends slightly beyond the 

 lower edge of the front, and as long as the lower edge of the front is wide. Maxillary palpi 

 visible, darker red than the labial palpi, about one-third as long as the latter, and situated 

 directly above them. Head behind the base of the antennae red, but each side of the front is 

 white. Apex of the fore wings not so acute as in A. selene. 



Wings whitish pea green; the squamation very thin. No traces of a basal line; a single 

 yellowish olive-green or brownish narrow faint line crosses both wings, in a straight course on 

 the fore -wings, but on the hinder pair the line is curved outwards opposite the ocellus; the line 

 is, on the fore wings, situated half way between the ocellus and the outer edge of the wing, and 

 in the hind wings nearer the outer edge. The costal band of the fore wings is redcUsh-madder 

 but white on the extreme edge on the basal two-thirds of the wing. Ocellus of the S fore wing 

 narrow oval, of the same width as the discal cell, with a central narrow oval clear space; on the 

 inside of this clear space yellow, succeeded by a very narrow pale-blue semicircle, and an outer 

 narrow black semicircle; on the outer side of the central clear space, i. e., the discal veins, the 

 ocellus is edged externally with greenish yellow. In 9 the ocellus is smaller, not extending to 

 either side of the discal cell; it is broader oval, and the blue semicircle is more distinct. 



Ocelli of the hind wings large, round; a short, inner black semicircle and the black ring 

 of which it forms a part interrupted at the origin of the discal veins, otherwise the colors are 

 as in the ocelli of the fore wing. On the underside of the wings the ocelli are distinct, but a little 

 duller in hue. They are white on the outer side, while in A. selene there is a pink-red semicircle 

 edged externally with white, and there is more black brown on the inside of the ocelli of the 

 fore wings. Fringe short, yellow, ochreous, or varying to white. Legs claret red. The tail of 

 the 9 is about one-half as long as that of the 3 , broad at the base and sharp at the end which 

 is directed outwards; it varies in width and length. 



Expanse of fore wing, s 110 mm.; 9 120 mm. 



Length of fore wing, S 55 mm. ; 9 60 mm. 



Breadth of fore wing, o* 32 mm. ; 9 39 mm. 



Length of hind wing, S 70 mm.; 9 66 mm. 



Length to base of tail, S 45 mm.; 9 56 mm. 



Length of tail, <3 30 mm.; 9 10 mm. 



Breadth of tail, S 5 mm. 

 This species, though plainly congeneric with A. selene, differs remarkably from that species 

 in the shorter broader fore wings and the very short tails; the difference between the sexes as 

 regards these appendages being very marked. Although all authors have apparently unhes- 

 itatingly referred this species to Tropaea, we have seen that in the venation and also the head 

 characters it is undoubtedly an Actios; moreover, the ocelli are not stalked as they are in 

 Tropaea.
