14 A. R. Grote's Notes on the Zygsenidse of Cuba. 



ECPANTHERIA, Hiibner. 

 Ecpantheria cyaneicornis, n. s. 



I have but a fragment of a male specimen of this species before me, 

 which is at once distinguished from the only other described Cuban 

 species of the genus, E. albicornis, Grote, by the dark bluish black 

 antennae. The primaries are white with sis series of blackish sub- 

 cyaneous, or brownish transverse annulations and spots, broadly marked 

 on costa. The third band shows a very distinct and large sub-quadrate 

 costal blotch spreading over the outer extremity of the discal cell, and 

 covering the discal cross-vein, the latter covered with darker scales so 

 as to resemble a <<; the terminal bands are composed mostly of inter- 

 spaceal spots, while the basal bands are formed by annulations. The 

 terminal series of reduced interspaceal spots, lying close to the external 

 margin, is discontinued at the apex. Under surface reflecting the or- 

 namentation of upper. What remains of the secondaries, show them 

 to be whitish, sub-diaphanous, with a dark costal squarish patch, be- 

 yond the middle, more apparent on the under surface. Vertex, white, 

 immaculate; white scales on the antennal scape in front; "collar," 

 white, with two super-lateral brownish spots ; " front," black. Thoracic 

 disc, white, behind with blackish, sub-cyaneous scales : four median 

 brownish annulations arranged in pairs; tegulse, white, with a central 

 annulation and a small dot, superiorly, on the inner margins. Legs, 

 blackish, narrowly annulate with white. Exp., £ , 1.80 inch.

Since E. cyaneicornis, may be readily distinguished from E. albicor- 

 nis, Grote, of which latter species I, as also Dr. Herrich-Schaeffer, 

 have examined several specimens, by its differently colored antennae, 

 as well as by other characters here given, I feel authorized to give this 

 partial description of a species which I trust will be more fully worked 



blackish brown; sometimes keeping the tawny tinge of primaries above and 

 having the secondaries obscure, sooty brown on either surface. In these darker 

 specimens the costa and anterior femora usually retain their reddish fulvous 

 color, otherwise the insect is evenly saturated with obscure shades on the dif- 

 ferent parts. As long as the ground color of the wings allows it, the simple, 

 darker, discal, diffuse spots, are always perceivable; this species is never band- 

 ed. Nine specimens average 1.20 inch in expanse, and 0.45 inch in length 

 of body, as near as may be. 



If my views with regard to the variability of our United States species of 

 Crocota are correct, we have not more than five well established species of the 

 genus, which with three from Cuba makes eight in all, to say nothing of C. lreta, 

 Walk., and C. eupraria, Walk., the latter South American, and neither of which 

 I have ever identified. I place Cytorus, Grote, as a subgenus of Crocota, Hub.
