37. OxeoscMstus cothon. 



^ . Exp. 2*35 in. Close to 0. tauropolis (D. &i H. Gen. 

 Diurn. Lep. p. 358, t. 66. f. 1) ; on the upper surface are two 

 additional yellow spots close to the apex of the anterior wing, 

 and another between the second and third branches of the 

 median nervure ; the spot on the hind wing is larger ; the 

 band crossing the hind wings through the end of the cell on 

 the underside is much broader, and includes a considerable 

 portion of the extremity of the cell ; the narrow band through 

 the middle of the cell is concave instead of nearly straight.

 black ; antennee yellow, black at the base ; apical third of 

 anterior wings, costa, outer margin, region of subcostal nervure, 

 a comma-shaped spot within and a triangular spot at the end 

 of the cell, three indistinct spots between the branches of the

39. Heliconius venustus. 



($ . Exp. 3*30 in. Like H. anactoria, Dby. (D. & H. Gen. 

 Diurn. Lep. t. 15. f. 4) ; but the spot over the end of the cell 

 of the anterior wing is wholly yellow, does not extend so far 

 towards the apex, and has a black spot at the origin of the 

 lower radial nervure.

Ohs. This species belongs to the H. vesta group ; but the 

 characters of its markings appear to be so strongly defined 

 that the insect may fairly be considered a distinct race, if not 

 a good species.
