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



front stained with brownish. Antennae, long, very strongly, heavily 

 and evenly pectinate; the antennal stem, above, covered with pale tes- 

 taceous scales ; the pectinations pale, dull brownish. Collar, stained 

 with brownish. Tegulre. dull yellowish testaceous, immaculate. Ab- 

 domen, ochreous yellow above, stained with brownish laterally and 

 towards anal segmeut, leaving this latter pale clay-color, or pale yel- 

 lowish testaceous. Palpi, a little paler than front, with scattered 

 brownish scales. Under thoracic parts clothed with mixed brown and 

 yellowish hair. Legs, mostly pale clay-color; posterior tibia with a 

 brown dot below the femoral joint. Exp., 1.75 inch. Length of body, 

 0.75 inch. 



9 . Resembles the male ; the general color is lighter. The gemi- 

 nate brown lines on the primaries are more interrupted and atomical, 

 wider apart, and the space within them is more purely yellowish. The 

 head, collar, base of the wings and abdomen, want the brownish dis- 

 colorations of the male. The secondaries are immaculate, and want 

 the median band, which is so characteristic in the opposite sex. On 

 their under surface, however, there are two costal marks, indicating its 

 obsolescence and a few dark scales, below the outer of these marks, on 

 the discal cross-vein. Antenna), whitish testaceous on their upper 

 surface ; beneath, shortly and evenly bi-pectinate. The thoracic 

 squammation is mixed with a few blackish scale points. The eyes are 

 covered with obscure reddish-purple hirusties. Exp., 2.40 inches. 

 Length of body, 0.85 inch.

A smaller species than E. luxa, Grote, which it much resembles. 

 The marks on the secondaries, which are perhaps shared by other 

 males of the genus, and the aggregation of brown scales on the outer 

 geminate baud of the primaries above first median nervule, are dis- 

 tinctional characters. 



The discovery of the male Euhalisidota, adds much to the compre- 

 hension of the generic characters. The large head and plumose 

 antennae, which remind one of Ammalo, Walker, together with the 

 Pattern of the Ornamentation, combine, in addition to the other charac- 

 ters I have elsewhere noted, to give a peculiar aspect to a very natural 

 genus of Moths which may be purely Cuban, but will, perhaps, receive 

 accessions from the other Islands of the Tropical Insular District. 

 The squammatiou is thin and powdery, especially on the o abdomen, 

 whence it is very easily removed by atrition. The genus appears to
