Cosmopteryx sancti-vincentii, sp. n. 



AntenncB brown, with a slender white line along each side reach- 

 ing to a white ring around the eighth joint from the apex ; apical 

 joint white. 



Palpi brownish, with slender whitish lines throughout their 

 length above and beneath. 



Head brown. 



Thorax brown, with a slender longitudinal central white streak. 



Fore wings brown to a little beyond the middle, apex brown, 

 separated from the basal half by a broad pale yellow band ; on the 

 basal half are four distinct slender white longitudinal lines — the first 

 along the costal margin from the base to the yellow band, some- 

 times slightly interrupted about its middle; a second from near the 

 base above the fold parallel with the first and about two thirds its 

 length ; a third below the outer half of the fold, short, commencing 

 at one half the length of the brown basal half and not reaching the 

 yellow band ; a fourth along the dorsal margin reaching to a point 

 opposite the commencement of the third ; the brown basal half is 

 bordered obliquely by two spots of raised pale golden scales, some- 

 times connected, the upper spot being slightly nearer to the base 

 than the lower one, at the outer edge of the upper spot is a minute 

 dot of jet-black scales ; at the outer edge of the broad yellow band 

 are two opposite pale golden spots, the one costal, the other, which 

 is the larger, dorsal ; between these spots the yellow colour of the 

 band is continued for a small space and emits into the brown apical 

 part of the wing a slender straight golden-yellowish line to the ex- 

 treme apex ; a lew whitish scales on the costa form an outer margin 

 to the second pale golden-yellow costal spot ; cilia greyish brown.
