is serrate beneath. In A. dredowi there are three strong teeth near the end of the 
ventral surface of the harpagones; there is no ascending lobe, and the spine of the 
tegumen in the middle of the cavity is double. The structure of these parts in Lime- 
nitis popult and L. lorquini is almost exactly like that of Adelpha, but L. camilla has 
the harpagones considerably produced into a depressed point,

There seem to be three closely allied species of this form, all having a fulvous trans- 
verse band on the primaries. The northern race is the insect here treated of, which 
spreads throughout our region from Southern Mexico to Panama, and thence passes 
into the Cauca valley as far as Frontino. Further south in Colombia a slightly modified 
form exists, having both the apex of the primaries and the distal half of the secondaries 
beneath much darker: this we propose to call Adelpha melanippe*. The third race is 
A. spruceana, described by Mr. Bates from a specimen taken in Ecuador by Mr. Spruce 
on the western slopes of Chimborazo; this on the underside resembles the Colombian 
A. melanippe, but on the upperside the transverse fulvous band of the primaries is as 
narrow as it isin A. lara. The male of the insect referred to by Boisduval 3 as Hetero-
