some new Species of Erycina. 227 



corresponding nearly in position with the bands on the upper 

 sides, the inner one the broadest and terminating before the apex 

 of the abdomen ; the posterior wings margined externally with 

 brilliant metallic blue, with a crimson oblong spot on the inner 

 margin corresponding with the portion of the band on the upper 

 side, which curves upwards : also an oval crimson spot under the 

 oval spot of the upper side, and an obscurely marked white spot 

 between the latter and the inner margin. Head, antennae, legs 

 and abdomen black, the latter having a yellow line on either side. 



Hab. Mexico. (Jurgensen.) 



Expansion of wings 2 inches.

This fine species was discovered by Mr. Jurgensen. The 

 description is from a male insect, and the female is unknown, if it 

 be not the Ery, Jurgensenii before described. 



Sp. 20. Erycina Inca. , (PI. XXI. fig. 6 and 6 a.) 



Black. The anterior wings above with a broadish bright golden 

 yellow transverse central band, curving inwards on approaching 

 the interior angle. The posterior wings each produced into a 

 short obtuse diverging tail, having above an ill defined blue patch, 

 with two paler points at the base of the tail, the blue colour in 

 certain lights extending over the surface of the tail; also four 

 white specks on the fringe of the outer margin of the wing, as 

 well as two specks of the same colour on the fringe of the inner 

 margin of the tail. Undersides of the wings tinted with rich 

 metallic blue, the black colour of the wings showing through at 

 the nervures and forming also a broad band common to both wings ; 

 in the anterior one corresponding with the yellow band on the 

 upper surface, and on the posterior wings running parallel to the 

 outer margin nearly to the base of the tail, where it curves upwards 

 and terminates on the anterior margin of the wing, having imme- 

 diately above its termination, a little distance from the margin, a 

 small round yellow spot, and immediately below a small oblong 

 rather obscure white spot. There is also on the anterior wings a 

 yellowish obscure spot near the base on the underside, which is 

 not visible until the wing be well expanded. Head, antennae, 

 body and legs black. Abdomen with a pale yellow line on each 

 side.
