Merocausta elfina -^p. nov. 



Forewings ochreous whitish, dusted and mottled with olive bromi atoms and 

 strigae, and suffused with the same tint in the central area lietween the two lines and 

 towards the hindmargin ; basal line beyond one-third, tliick, reddish brown ; ano-ulated 

 beneath the costa, then running to inner margin parallel to hindmargin ; second line 

 at four-fifths, olive brown, forming a prominent blunt tooth towards hindmargin below^ 

 costa, then running irregularly sinuous inwards, and approaching the first line on the 

 inner margin ; hindmargin below apex and abo\e anal angle red brown, as are the 

 fringes: apex itself with a small pale spot; submarginal line indicated' by black dots 

 on the veins. Hindwings the same, but with only the outlines of a central band : 

 fi-inges and whole hindmargin narrowly olive brown, with the row of dots as in fore- 

 wings, but less distinct. Underside yellow, except towards apex of forewings, which 

 is whiter, with the markings deeper brown. Thorax, abdomen, and underside with 

 legs ochreous white, spotted with brow^l ; vertex, antennae, top of face, and tips of 

 palpi brown. This description is made from a ijuite fresh specimen from Corcovado ; 

 the others, which seem to be all more or less worn, have lost the deeper brown tint, 

 and are dirty whitish, with dull olive markings only. These are from Santos and 

 S. Paolo.

Crocopteryx Guen. 

 At p. 72, vol. i., Guenee proposed this genus for a group of species, one of which 

 he himself mentions as having been figured by Hllbner under the generic name of 

 Pyrinia. This name must, therefore, supersede Guenee's. In the diagnosis Guenee 

 gives "antennae long, simply pubescent " ; but after the description oiei-ythrocephalata, 

 p. 73, says, " This is the only one of the genus, as far as is known at present, of which 

 the antennae (c?) are pectinated. For this species, then, which thus differs from 

 the rest, I take it that Crocopteryx Guen. should be retained, with the correction 

 "antennae pectinated.''

Distinguished from Syssaura Hlib. by the fully jiectinated antennae of the J, 

 and the less falcate forewings. 



Pyrinia brunneata sp. nov. 

 Forewings dull smoky fulvous, dotted and sufTused with darker fulvous; the 

 markings blurred and indistinct ; these consist of a darker basal patch, an angulated
