480 RHOPALOCERA. 
both discocellulars are atrcphied, the upper meets the subcostal some way beyond the 
first branch, the lower the median a little beyond the second branch; the costal side of 
the cell is shorter than the median side. 
The terminal joint of the palpi is long and slender, =+ middle joint; the antenne 
have forty-seven joints, and terminate in a slender club. 
The harpagones in the male secondary sexual organs are simple lobes pointed 
outwards, and are setose on the upper and lower regions, as well as towards the point; 
the penis is short, slightly tapering and decurved throughout its length, and the usual 
strap proceeds from its middle to the base of the harpagones.

This is not an uncommon species in Nicaragua, and thence along the isthmus to 
Panama. In the former country it was obtained in some numbers by the late 
KE. M. Janson, after whom Mr. Butler named it. The nearest South American ally is 
A, lagus, from the female of which it seems constantly to differ in having the wings 
suffused with blue.

The only collector who has as yet met with this species is Belt, and he obtained 
several examples, some of which are now in our possession. Its position in the genus 
of Aricoris is open to question as the similarity of the sexes is an exceptional feature ; 
but until we have material for dissection we leave it where Hewitson placed it.
