Mesosemia olivencia. 



(S. Closely allied to M. Metope (Hewits. Exot. Butt. Mesos. f. 64, 65). 

 Wings, general colour, and ocellus very similar, but diflPers on the 

 upper surface, in the fore wing, by the absence of the bluish grey 

 subapical spot, and in the hind wing by two or three of the black 

 streaks passing across the wing to the abdominal margin. 



Fore wing above blackish brown, with darker ocellus, and near the 

 outer margin a narrowish grey streak extending from the costa to the 

 hind margin near the hind angle. Hind wing blackish brown on its 

 basal half, the colour terminating in three wavy streaks which pass 

 across the wing ; three shorter dark streaks extend a short distance 

 from the apical margin ; rest of wing white, except near the dark 

 streaks, where it is bluish grey. 



Beneath light brown ; ocellus with two dark streaks on its inner side 

 and three on its outer side; beneath the ocellus there are three 

 streaks on each side, the inner of which meet before the hind margin ; 

 outer half of the fore wing without dark streaks, but having a 

 narrowish white belt extending from the costa to the hind margin, 

 near the hind angle. Hind wing light brown, outer border broadly 

 white. Across the disk (and the central black spot) is a broad darker 

 brown belt, the rest of the brown part crossed by numerous fine, 

 wavy, dark brown streaks. A macular line traverses the white hind 

 border.

Mesosemia Philocles, Linn. 



This species occurs under three distinct forms in the Amazons 

 region, none of which accord very closely with the figures of 

 Clerck and Cramer ; they are as follows : — 



Mesosemia l^tifica. 



c? . The fore wing has a fine light-blue patch commencing in a point 

 near the base, enlarging towards the ocellus, and, beyond it, curving 

 round and ending in a point at a short distance from the hind angle. 

 The hind wing has a large space on the disk of a light-blue colour, 

 and five short black streaks proceeding from the costa, the submarginal 

 one sometimes extending in a broken line to the anal angle. Beneath, 

 the dark submarginal line of the fore wing extends from the hind 

 angle to the costa.

c? . The blue patch of the fore wing has the same extent as in Cramer's 

 figure, and shades into white exteriorly in the same way. The hind 

 wing also resembles Cramer's figure in the almost entire absence of 

 the discal blue, the thickness of the costal streaks, and the double 

 black marginal lines. My specimens differ on the underside from
