XYLORTCTID^. 469 



two less distinct on costa : cilia whitish, tinged with ochreous 

 towards base. Hindwings with 3 and 4 short-stalked, 5 approxi- 

 mated ; ochreons-whitish ; cilia concolorous. 



Fkench Guiana, li. Maroni ; one specimen. Very close to 

 immimda, but differs in form of costal fold, which is longer and 

 less broad (in immunda it extends on costa to 1 and its edge 

 is widely remote from plical stigma); in this character it resembles 

 l>eroj^1iora , but differs in colour of hindwings. 



Stenoma perophora, n. sp. 



S . 36 mm. Head ochreous-whitish. Palpi ochreous-whitish, 

 second joint dark fuscous except apex. Antennal ciliations j|. 

 Thorax whitish-fuscous. Abdomen grey, aoal tuft whitish-ochreous. 

 Forewings elongate, posteriorly dilated, costa gently arched, with 

 broad semioval membranous fold extending from base to middle 

 and reaching | across wing, tilled with flocculeiit scales, apex 

 obtuse-angled, termen almost straight, vertical ; 2 separate • 

 whitish-fuscous ; plical and second discal stigmata small, dark 

 fuscous, plical touching edge of costal fold; a faint strongly and 

 irregularly curved interrui ted fuscous shade from middle of costa 

 to 4 of dorsum ; a curved series of cloudy fuscous dots from beneath 

 costa at 4 to near tornus, sinuate inwards towards costa ; a terminal 

 series of dark fuscous dots, and two fuscous dots on costa near 

 apex : cilia whitish-ochreous, outer half whitish. Hindwings with 

 3 and 4 short-stalked, 5 approximated; grey, apex suffused with 

 pale ochreous ; cilia whitish-ochreous. 



Peru ; one specimen. Also very close to immunda, but distin- 

 guished from both it and thylacandra by the more elongate fore- 

 wings and grey hindwings. 



Stenoma expilata, n. sp. 



6 . 26-31 mm., 5 38 mm. Head ochreous-whitish. Palpi 

 white, second joint fuscous except apex. Antennal ciliations of 

 c? 2. Thorax and abdomen whitish-ochreous. Forewings elon- 

 gate, posteiiorly dilated, costa gently arched, apex obtuse-angled, 

 termen almost straight, vertical ; 2 separate ; whitish-ochreous ; 

 extreme costal edge whitish ; stigmata dark fuscous, first discal 

 indistinct, plical obli(iuely beyond it ; a faintly indicated irregularly 

 curved fuscous shade from middle of costa to | of dorsum ; a curved 

 series of cloudy fuscous luuulate dots from -i of costa to dorsum 

 before tornus, sinuate inwards beneath costa ; a marginal series of 

 small dark fuscous dots round apex and termen : cilia ochreous- 

 whitish. Hindwings with 3 and 4 connate, 5 nearly approximated ; 

 whitish-yellowish, in $ faintly greyish-tinged on basal half ; cilia 

 yellow-whitish. 



British Guiana, E,. Demerara ; French Guiana, Godebert and 

 Nouveau Chantier ; five specimens. Almost indistinguishable in 

 form of wings, colour, and marking from immunda, but the J' has 

 no costal fold.
