Stenoma palpalis Zell. 
CrytoleoJiia palpalis Zell., Hor. Ross, xiii, 275 (1877), alleged 
from Bengal, has long been a puzzle to me, but I have lately 
perceived that the description undoubtedly points to a Stenoma of 
the grandis group, restricted to South America. Zeller has un¬ 
fortunately (by an unusual omission) not stated the size, and there 
are 8 or 9 similar species, besides doubtless others not discovered, 
but it seems to be reasonably consistent with S. auccoleuca Meyr.', 
for which I think it may be adopted. The reputed locality Bengal 
may perhaps have been a mere slip of some one for Brazil, presum¬ 
ably the real place of origin. 
Stenoma diametrica, n. sp. 
6 . 18 mm. Head, thorax white, tinged grey on sides. Palpi 
white, second joint with grey streak, terminal joint tinged giey. 
Forewings oblong, termen faintly sinuate, rather oblique; 2 from 
near angle, 7 and 8 connate, 7 to termen, 8 to costa; violet-white, 
a few scattered brown scales ; a brown spot beneath base of costa ; 
a light violet-grey band sprinkled brownish extending along dorsum, 
from base to -i, including a brown trapezoidal blotch resting on 
dorsum before middle, becoming blackish towards dorsum, widened 
upwards and discal edge twice dorsal; first discal stigma forming a 
dark brown dash ; wing beyond a line from middle of costa to.
