I am generally loth to merge together genera which are 
difterentiable on any structural character, but the group 
which I am citing under the oldest name of Few, H.-S., 
seems—with the possible exception of Stenaspilates, Pack. 
—so entirely homogeneous in all respects save the $ 
antennal structure, and a division upon that character 
sometimes separates such evidently close allies, that I 
feel constrained to regard the distinction as at most sub¬ 
generic. With the type of Stenaspilates {meskearia, Pack.) 
I am not personally acquainted ; but Mr. J. A. Grossbeck 
writes me that it differs little from Pew except in the ^ 
antenna. Stenodonta, Warr., Nov. Zook, xii, 379, probably 
forms another section, unless equivalent to Stenaspilates ; 
but as the ^ is unknown, and I have no material for study, 
I leave it provisionally separate. It may be added that 
the application of the names Pew and Azelina was long 
reversed; vide Warren, Nov. Zook, xii, 367. The name 
Pew belongs typically, as is there shown, to the species 
with simply ciliated ^ antennae, while Butler, Tr. Ent. 
Soc. Lond., 1882, 356-7, virtually restricted Azelina to the 
pectinated species. 
The Argentine representatives of this genus are mostly 
of small size, in comparison with many of those from the 
more northern parts of the continent.

Tucuman, in coll. Dognin. 
A widely-distributed species, ranging from Central 
America and the West Indies to southern Brazil. Guenee 
described it from Brazil. I cannot see any appreciable 
geographical variation, nor, indeed, any really noteworthy 
individual variation.
