Peeigonia, Walk. 

 Perigonia taci'ta, sp. n. 



Primaries bright reddish brown, with a large A -shaped 

 darker brown mark extending from the middle of the inner 

 margin nearly to the costal margin, edged on both sides with 

 greyish-brown lines ; two small black dots at the end of the 

 cell, and several indistinct undulating dark brown lines 

 crossing the wing from the costal margin to near the anal 

 angle; several silvery- brown lunular-shaped marks close to 

 the apex : secondaries dark brown, broadly banded with 

 chrome-yellow from the base to near the apex ; several very 

 indistinct greyish lines cross the wing from the anal angle 

 towards the apex. Underside of all the wings yellowish 

 brown, and reddish brown along the outer margins. Head, 

 thorax, abdomen, and legs dark brown ; antennae yellowish 

 brown. Expanse 2^ inches. 



Hab. Panama, Volcan de Chiriqui {Trotsch, Mus. Stau- 

 dinger) . 



This species is most nearly allied to Perigonia stulta^ 

 Herr.-Sch., but very distinct from that insect. 



Aleuron, Boisd. 

 Aleuron tachasara, sp. n. 



Primaries brownish olive-green, crossed from the costal 

 to the inner margin by five indistinct waved dark brown 

 lines ; a silvery grey mark on the costal margin nearest the 

 apex, almost crossing to the middle of the outer margin and 

 then extending to the anal angle : secondaries blackish 

 brown, greenish at the base and along the costal margin to 

 the apex. Underside : primaries, the basal half brownish 

 black, the outer half olive-brown with an indistinct silvery 

 line crossing from near the apex to the inner margin : secon- 

 daries olive-brown, with a silvery gloss extending over the 

 wing from the base to the central whitish band, which crosses 

 from the costal margin near the apex to the inner margin. 

 Head, thorax, abdomen, and legs brownish olive-green, 

 the underside of the thorax and abdomen paler than above ; 

 antennae brown. Expanse 4 inches. 



Hab. Panama, Volcan de Chiriqui [Trotsch, Mus. Stau- 

 dinger) . 



This fine species is very distinct from all I have seen, but 

 it is allied to A. chloropteraj Perty, from which it is at once
