This species has been erroneously referred in our lists to O. jun- 

 cealis Guen. from South America. The two species are really distinct. 

 I have a fine series of the true juncealis from Brazil and the Guianas 

 (W. Schaus).

Oligostigma vittatalis, new species. 

 Body brown with whitish on sides of thorax and abdominal rings. Fore wings 

 silvery white ; basal third dark brown, cut by a white subbasal line and one just at 

 edge, cutting off a linear dark inner line ; outer line linear, dark, curved to below 

 cell, then straight to margin, the curve to costa filled in with dark over the discal 

 mark, which shows obscurely as two parallel darker lines. A broad subterminal 

 shade, separated by white from the outer line and terminal dark shade, the latter 

 narrow, sinuous; fringe spotted black and white with a black basal line. Hind wing 

 marked in the same manner, the outer line a little less decidedly bent, the terminal 

 shade enclosing faint orange shading at the margin. Expanse, 14 to 18 mm.
