Stenoma psilomorpha, n. sp, 



J . 37 mm. Head ochreous-wliitish, crown tinged with fuscotis. 

 Palpi ochrcous-white, second joint dark fuscous except apex. 

 Antennal ciliations 2. Thorax whitish-grey. Abdooien pale 

 greyish-ochreous. Forewings elongate, rather narrow, gradually 

 dilated posteriorly, costa gently arched, apex obtuse-angled, termea 

 faintly sinuate, vertical; 2 separate; whitish-fuscous; extreme 

 costal edge whitish ; stigmata dark fuscous, plical obliquely beyond 

 first discal ; a faint fuscous irregularly curved shade from beyond 

 middle of costa to | of dorsum ; a curved series of fuscous lunulate 

 dots from ^ of costa to dorsum before toruus, somewhat sinuate 

 towards costa; a terminal series of dark fuscous dots: cilia 

 ochreous-whitish. Hindvvings with 3 and 4 short-stalked, 5 ap- 

 proximated ; whitish-oc-hreous ; cilia concolorous. 



Peru ; one s])ecimen. Very similar to the preceding species, 

 and also without costal fold, but readily distinguished by the 

 narrower forewings, less dilated posteriorly. 



Stenoma liemilampra, n. sp." 



cJ . 30-34 mm., $ 40 mm. Head whitish-violet-fuscous. 

 Palpi -whitish-violet- fuscous, second joint suffused with brown, 

 with dark fuscous streak above towards base. Antennal ciliations 

 of (5 hardly 1. Thorax velvety-blackish, patagia whitish-violct- 

 fuscous. Abdomen dark grey, towards apex ochreous-orange. 

 Forewings elongate, jjosteriorly slightly dilated, costa in 6 almost 

 straight, in 5 slightly arched, apex rounded-obtuse, termen nearly 

 straight, little oblique ; 2 se])arate ; violet--fuscous, with whitish 

 gloss, costa suffused with dark fuscous ; an indistinct pale cloudy 

 straight line, edged posteriorly with darker, from ^ of costa to 

 middle of dorsum ; a strong black transverse mark on end of cell ; 

 a pale cloudy straight line, edged anteriorly with darker, from |- of 

 costa to tornus ; a terminal series of black dots : cilia fuscous. 

 Hindwings with 3 and 4 connate, 5 ai)proximated ; grey ; a])ical 

 half ochreous-orange ; cilia whitish-ochreous, on dorsum suflused 

 with greyish. 



French Guiana, E. Maroni ; thi-ee specimens. With the increased 

 material now available 1 hnd the genus Gonioterma Wals. also 

 untenable, and it must be merged in kitcnoma like the rest. ]\ir. 

 Eusck, in adoj)ting this genus (Proc. U.S. Nat. Mus. xl, 224) 

 italicises tlie only distinguishing cliaracter, vein ,8 of the forewings 

 to termen below apex, yet in the same paper he has described five 

 species {piaroni, vanis, rosa, Stella, ejuma), referring the first two to 

 Stenoma and the last three to Gonioterma, though the termination 

 of vein 8 in the first two is clearly below its position in the last 

 three ; I should regard 8 as terminating below the apex in the first 

 two and just at the apex in the last three, which would reverse his 

 generic determinations for the whole five. The fact is that the 

 apex is very obtuse or rounded-obtuse in all these, and if accurate 

 comparison is not made it becomes easy to assume tlie (errnin/ition
