PERICOPIS. 109 
sides of the abdomen deep yellow, the underside yellowish white; antenne and palpi black, collar red ; 
legs black on the upperside, yellowish white beneath. Expanse 27 inches. 
Hab. Panama, Volcan de Chiriqui (Ribbe, mus. Staudinger). 
I have only seen a single example of this beautiful species; it is quite unlike any 
other known to me.

Thebrone jansonis, Butl. Ann. & Mag. Nat. Hist. 4th ser. xvi. p. 164. 
Male. Primaries semitransparent, brownish black, with the lighter bands in the same position as in the female ; 
secondaries white, the outer margin and apex broadly banded with black, a red spot at the anal angle, 
the veins black: head and thorax black, yellow in front; abdomen black, striped with greyish white, 
anus yellow; palpi and antenne black. In some specimens of the male the secondaries are pale yellowish 
white, in every other respect they agree with what I consider to be the typical form. 
Hab. Nicaraeua, Chontales (Belt); Panama, Volcan de Chiriqui (¢, both forms 9, 
Arcé, mus. D.; and Ribbe, mus. Staudinger), Bugaba (6, both forms 2 , Champion). 
It is quite possible that the yellow form may prove to be a distinct species, but for 
the present I think it better to place it as a variety of the male of P. jansoni, the only 
difference being the pale yellow colour of the secondaries. Chetone arema, Boisd., 
placed with this species with doubt by Mr. Butler, is a very distinct species, and nearest 
allied to P. marginalis, Walker, but quite different from any other known to me.

(Belt). 
After carefully comparing the types of the above-mentioned species with the series of 
specimens before me, I see no reason for retaining Boisduval’s and Butler’s species as 
distinct, the chief differences being the width of the marginal band of red spots on the 
secondaries of the females. In some specimens of the males the light-coloured markings 
of the primaries are much whiter than in others; in these points they vary to a consi- 
derable extent, in fact no two specimens are exactly alike.
