178 A. R. Grote's Notes on the Zygsenidae of Cuba. 



discal cell itself, is closed. The median nervure throws off first, second, 

 third and fourth ra. nervules very much as in Eudryas. A compari- 

 son of the entire nervulation in both sexes of Euscirrhopterus, with that 

 of Eudryas, shows the affinity of the two genera. The neuration of the 

 secondaries is almost identical with that of Eudryas. 



In the female, the anterior wings are straight along the entire costal 

 length, more elongate and pointed than in the male, while the neura- 

 tion is normal, so to speak. The second s. c. nervule is straight, not 

 curved as in the male; the second, third and fourth s. c. nervules run- 

 ning approximate and being similar in their course. This is caused 

 by the absence of the apical enlargement. The neuration of the se- 

 condaries is identical with that in the male, but these are larger. 



The % antennae are simple, slightly scaled on their upper surfaces 

 and swelled towards their tips. The 9 antennae seem a little longer 

 and are linear, being nowhere thickened throughout their length. In 

 both sexes they are rather stout and, especially in the female, semi-an- 

 nulate, remiuding us somewhat of the antennae of Lyeamidae. The 

 genus is, I think, higher than Eudryas, though the structural sexual 

 dissimularity may be assumed as a degradational character. 



Euscirrhopterus Poeyi, n. sp. 



The male is darker than the female. The primaries are clothed with 

 rough, mixed brownish and pale scales, which are sparsely laid on along 

 the disc and on the inferior external parts. The internal margin, un- 

 til before the angle, and the apex, are clothed with darker and closer, 

 thicker scales. A large dark spot at the extremity of the disc. Two 

 geminate, transverse, demi-bands, with pale internal scales, on internal 

 margin. These are angulated and wide apart. The secondaries are 

 similarly colored with the primaries, but the scales are very thinly laid 

 on, especially centrally. A dark shade along external margin, widen- 

 ing toward anal angle, where are some terminal, paler brown marks. 

 Internal margin fringed and covered with loug ochreous-yellow hair ; 

 fringes whitish. Abdomen, ochreous-yellow. The female ornamenta- 

 tion, while much the same as that of the male, more plainly recalls the 

 ornamentation of Eudryas. The scales are evenly and closely laid on. 

 The primaries are covered with mixed brownish and pale scales along 

 costal margin, and broadly so along external and internal margins. 

 The center of the wing, from just beyond extreme base to end of dis- 

 cal cell, is covered with a white stripe, widening as it proceeds. At 

 the extremity of the disc, it is interrupted by a large, oblique, dark 

 discal spot, margined on both sides by dark sinuate lines, which meet be- 

 low, but are discontinued superiorly, where the discal spot is merged with
