cd. Internal, or sub-median nervure, nearly straight and parallel with 

 the margin. 



Secondaries, large, somewhat pyriformj costa long, straight, depress- 

 ed towards the apex, which latter is blunt but rather produced; exter- 

 nal margin rounded, a little produced medially; anal angle impromi- 

 nent ; internal margin straight. The nervulation recalls Callalucia ; 

 the second and third m. nervules spring from one point at the extremi- 

 ty of the nervure; first, a little removed, springs from the cross-vein 

 which closes the discal cell ; fourth, at a point about two-thirds of the 

 length of the nervure from the base, thus its position is here much 

 nearer removed towards the extremity of the m. nervure, than its ana- 

 logue of the primaries. This removal of the fourth m. nervule towards 

 the base of the nervure, seems to influence the shape of the anterior 

 wings. 



This finely and thinly scaled genus is very distinct, in the shape of 

 the wings, from any of the genera allied to Pericopis, that I have been 

 able to compare, and is readily distinguished from that genus by the 

 singularly straight external margin of the primaries and their triangu- 

 lar shape.

 1866). 



9. Head, blackish, with two lateral white bands on the "front," 

 behind the antennal insertions are two white dots. "Collar," blackish, 

 dotted with white. Thorax and patagia, anteriorly, blackish dotted 

 with white; behind, the thoracic parts are very pale greenish-yellow. 

 Abdomen, very pale greenish-yellow, without markings, except a later- 

 al, brownish, distinct, stigmata] line. Legs and under thoracic surface, 

 pale, the former striped with blackish or brownish outwardly. 



Wings, sub-diaphanous, very pale greenish-yellow. Primaries black- 

 ish along costa to basal third; these dark scales are margined interior- 

 ly by the median nervure, and enclose three scarlet patches, which are 

 fused on the under surface and here hardly disconnected. At the ex- 

 tremity of this dark costal patch, the dark scales are continued down- 

 wards, forming a distinct oblique baud, joining the internal margin 

 near tin' angle and fusing with the dark terminal color of the wing. 

 Heyond this, the ground color of the wing forms a coincident, broad, 

 oblique band. Terminally, the wing is blackish, the dark space being 

 very wide on costa, commencing at about its middle, and very narrow 

 at internal margin where it merely covers the angle. Superiorly, two 

 sub-equal, oblique, sub-diaphanous, broad, pale bauds, intersected by
