ECPANTHERIA, Iliibner. 

 Eopanthcria albicornis, n. s. (Plate 4, fig. 4, J.) 



The Cubiin species is readily distinguished from E. scribonia Iliib. 

 by its smaller size, white antennae and the shape of the % posterior 

 wings, since these are but slightly produced at anal angle, being similar 

 to those of the 9 i'^ this respect. These characters, either singly or 

 together, will equally separate E. albicorms, from the species described 

 by Mr. Walker in the British Museum Lists, with the the exception of 

 E. simplex Walker, which is from a different locality, and in which 

 the abdomen is said to be "orange above, white at the tip, with brown 

 and white bands at the base, and with a row of blue spots along each 

 side." Hence the species differs markedly from the Cuban species in 

 which the abdomen is cyaneous above, with narrow bands, and resem- 

 blinj; somewhat that of E. scribonia. 



Head, clothed with white scales between the antennae and behind, 

 immaculate. Lower clypeal surface, beneath the antennal insertion, 

 covered with pale blackish scales. Palpi, clothed with pale blackish 

 scales. Antennae, entirely white above, from the base to the tips; be- 

 neath, the articular appendages, in both sexes, are pale brownish. 

 "Collar" white, with two sublateral, approximate, brownish annuli. 

 Patagia, white; an incomplete annulus in front, which is generally 

 joined on the inner margin to a second, larger and occupying the pos- 

 terior half of the tegulae. Normally there are six irregularly shaped 

 annuli on the thoracic disc, which latter is white. Abdomen dark cy- 

 aneous-blue above, with brownish and whitish ba.sal hairs. The sub- 

 basal and median segments narrowly banded with yellow anteriorly. 

 Sometimes these yellow bands are sub-obsolete, the yellow hairs being 

 gathered dorsally into determinate maculations. Anal segments, entirely 

 cyaneous ; anus clothed with dark brownish or pale blackish hairs. 

 Beneath, white, sometimes with a few brownish scales. Thoracic parts 

 beneath, with mixed whitish and brownish hairs; legs white, all the 

 femora, tibiae and tarsi, spotted with brownish. 



Wings, whitish; anterior pair crossed by six bands of unequal brown- 

 ish annuli, the fourth, from the base of the wing, broken beyond the 

 disc, where a few additional annuli are variously clustered. The pos- 

 terior wings are more thinly covered with scales; costal marks distinct, 

 and tliere is generally a short terminal series of brownish marks below 

 costal angle, within which sometimes a series of brownish annuli, more 

 or less filled in with dark scales. In the male this inner band is some- 

 times wanting, when the wings are destitute of markings, except those 

 on the costa and terminally below costal angle. The anal angle is but
