densely and evenly pectinated; the slender pectinations are long, and 

 frradually and slightly decrease to the tips. Head reddish-ochraceous, 

 inipunctate. "Collar" with a slight stone-colored or obscure slaty- 

 brownish shade, inipunctate. Teirula; reddish-ochraceous, fringed in- 

 wardlywith didl brownish hairs. Thoracic disc, brownish. Abdomen 

 pale dull reddish-ochraceous, with fine, distinct, very dark brown bands 

 above; the first and second basal, not continued across; longer sub-tufts 

 of hair clothe the abdomen above at base and extend over the first and 

 S2Cond segmentary bands, thus rendering them incomplete. Palpi, 

 prominent, exceeding the front, third article conical, finely scaled, brsal 

 articles clothed with rather bright reddish longer scales. Under tho- 

 racic parts, clothed with rather bright reddish S({uammation. Tongue, 

 long, testaceous. Legs, with minute spurs on the middle and hind 

 tibia?, well developed ; femora clothed with rather bright reddish squam- 

 mation ; tibae and tarsi pale brownish.

From the character of Cramer's figure of Ammaln Hdops^ from Su- 

 rinam, I can rely upon the following differences which seem to separate 

 the two allied species. The vertex, teguhie and base of the anterior 

 wings show very distinct, large, black dots in A. ILdops, which are en- 

 tirely wanting in ^1. impunctus., m. The pre-basal abdominal bands are 

 carried entirely across; the p(^sterior wings are much darker and 

 brighter, the markings of the upper surface of anterior wings are quite 

 difi'erent in detail, while the two species are very similar in general 

 coloration. This species shares the characters laid down for the genus 

 by Mr. Walker, but the antennfe are more plumose in the 9 than indi- 

 cated in the diagnosis; the discal fold, prolonged beyond the cell, is 

 very distinct; the abdomen extends a little beyond the secondaries; 

 the genital structure is quite concealed. The typical species of Iliib- 

 ner's genus F(;locliijta are generically distinct from A. Ilelops, which 

 he associated with them. According to Cramer, the % antennae of JL. 

 Htlops are ''plumacees," agreeing with "S A. impunctus, m., while those 

 of the 9 <ire "filiformcs" as, indeed, they are represented in the Plate, 

 where they are shorter, slenderer and darker colored than those of 9 -4.
