upon the fore wings ; a costal streak, three oblong apical spots, and three 

 triangular spots along the outer margin of the hind wings, all silvery white. 

 Expanse 2 '75 inches. 



Head, thorax and abdomen, above blackish brown, below the thorax is 

 spotted with white, but no yellow stripes as are in Jemima ; abdomen below 

 yellowish. Antennse blackish at base, orange brown beyond, darkening 

 towards the apex. 



The/emale does not dififer from the male, save in the more rounded wings, 

 and in intensity of coloration. 



Hab.—lnsa.ga.s\igA, New Granada. (Coll. Tryon Reakirt.) 



57. Mechanitis Fkanis, nov. sp. 



Very closely allied to Meek. Menapis, Hewits. 



Differs chiefly in the larger size of the fulvous basal area of the fore wings ; 

 in tlie invariable presence of a large rounded black spot, between the first and 

 second median veins ; and in the more common division of the black portion 

 of the hind wings into a central belt, and a terminal border. 



Underneath as in Menapis, with the above diflerences. 



Hab. — Insagasuga, New Granada. (Coll. Tryon Reakirt.) 



I can hardly believe this to be a local variety of Menapis ; both were cap- 

 tured at the same place, and time, and throughout a long series of specimens 

 I find the differences to remain constant. 



58. Pykkhopyga Bogotana, nov. sp. 



Upper surface black, brilliantly glossed with steel blue ; the posterior two- 

 thirds of the outer margin of the hind wings, is bordered with bright orange 

 brown, broadest towards the anal angle, gradually diminishing to the other 

 extreme point, and scalloped interiorly. 



Underneath the same, with perhaps less shining reflections. 



Body and legs glossy blue-black, with orange-brown palpi. Antennae 

 black. 



Expanse 2*25 inches.

59. Pyegus alana, nov. sp. 



Upper surface white, faintly tinged with yellowish ; costa of primaries, and 

 a large apical patch, covering the outer two-fifths of the wing, dark brown ; 

 the latter, which is concaved interiorly, and traversed by darker brown 

 veins, presents a transverse, indistinct, white macular, narrow aubapical 

 band, frequently entirely obsolete. 



Secondaries with an irregular narrow brown border, from which brown 

 veins rise a short distance into the area of the wing. 



Fringe of primaries brown ; of secondaries, first narrowly white, bordered 

 externally with brown, forming two parallel lines around the whole outer 

 margins. 



Underneath chiefly as above, with the brown more diluted, and the white 

 subapical baud of tlie primaries, and the whole white surface of the secon- 

 daries, replaced with ochreous yellow ; the former consists of six distinct 

 spots, of which the two lower are the largest, and extend to the outer margin ; 

 the white basal area of the fore wings is more or less tinged with yellow. 



On tlie secondaries, the veins are all lined with black, and there are two 

 diffused brown patches ; one below the centre of the wing and towards the 

 abdominal margin, the other on the outer edge near its middle. 



Expanse 1'70 inches. 



Thorax and abdomen above black, clothed with whitish haira ; the latter, 

 below, yellow, with a double brown stripe ; head palpi, and antennae brown ; 

 a yellow collar above the first. 



Hab. — Insagasuga, New Granada. (Coll. Tryon Reakirt.)
