468 EXOTIC MICEOLEPIDOPTEKA. 



with a fiisco'is spot. Hindwings with 3 and 4 connate, 5 approxi- 

 mated ; whitish, towards apex faintly ochreous-tinged ; cilia whitish, 

 towards hase ochreous-tinged. 



British Guiana, Bartica, Mallali, and R. Demerara, from 

 December to March (Parish)- eight specimens. Excessively 

 similar to cholerojjtihi, but the J is without the dorsal hairpencil 

 of hindwings; the difference in the cilia of forewings, and the 

 jiresence of the fuscous shade behind cell are good but easily over- 

 looked distinctions. 



Stenoma impurata, n. sp. 



S. 17 mm. Head white. Palpi white, second joint dark 

 fuscous except towards apex. Antennal ciliations 3. Thorax and 

 abdomen ochreous-whitish. Porewings elongnte, posteriorly di- 

 lated, costa gently arched, apex obtuse-pointed, termen slightly 

 sinuate, nearly vertical : 2 separate, 8 and 9 short-stalked or 

 separate ; ochreous-whitish : cilia ochreous-whitish, with thick 

 rather dark fuscous basal line from a])ex to near tornus. Hind- 

 wings with 3 and 4 connate, 5 approximated; ochreous-whitish; 

 cilia ochreous-whitish, with fuscous basal line round apex and 

 upper part of termen. 



Dutch Guiana, Paramaribo, in July ; one specimen. Closely 

 allied to leueana, in which species also veins 8 and 9 of forewings 

 are stalked, apparently constantly. 



Stenoma immunda Zell. 



This was described from two $ examples ; I regard theBraziliaTi 



V one, which was in Zeller's own collection, as the type, and identify 



^tectelln Walk, with it as a synonym. The other example was 



probaljly not the same species ; I have only seen the true immunchi 



from Brazil, but there are several extremely similar species, of 



which four are described hereafter. 



Stenoma thylacandra, n. sp. 



^. 32 mm. Head ochreous-whitish, face fuscous except in 

 middle. Palpi ochreous-whitish, second joint dark fuscous except 

 towards apex. Antennal ciliations 1. Thorax fuscous-whitish. 

 Abdomen ochreous-whitish. Forewings elongate, moderate, pos- 

 teriorly dilated, costa gently arched, with broad semioval membranous 

 fold extending from base to middle and reaching nearly | across wing, 

 filled with flocculent scales, apex obtuse-angled, termen almost 

 straight, little oblique ; 2 separate ; pale whitish-fuscous ; costal 

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

 plical touching edge of costal fold ; a faint cloudy line of fuscous 

 irroration from beyond middle of costa to f of dorsum, strongly 

 curved outwards in disc; a series of cloudy fuscous lunnlate dots 

 fi-om beyond | of costa to dorsum before tornus, curved outwards 

 in disc ; a series of dark fuscous marginal dots round termen, and
