(^) Nueva Roma, two specimens. 
I have not been able to identify Berg’s species, but 
quote it for bibliographical completeness. He gives no 
description, and his figure (uncoloured) is only mediocre; 
it suggests a small glossy Larentiid, with very ordinary 
forewing, and having, as the most noteworthy feature of 
the hindwing, a double series of postmedian (or rather, 
postmedian and subterminal) vein-dots. But Berg says 
that in some specimens these are entirely wanting. He 
evidently, therefore, knew other specimens which he 
referred here, besides the two from the Rio Negro 
expedition, but how many species he confounded together, 
I am not prepared to say. In the British Museum there 
is a specimen of Perizoma impromissata, Walk., from 
Buenos Aires, which he himself presented as Glaucopteryx 
tepidata. Altogether it is most improbable that his 
tepidata, or any part of it, was correctly identified as that 
of Guenee—nov. nom. for Tephrosia undidaria, Blanch. 
This latter was from Chili. (^) 
Hoplolygris (Prout), nov. gen. 
Frons protuberant, with strong projecting horny plate above 
(subconcave in horizontal plane), shorter plate below, and strong 
projecting tufts of hairs laterally ; palpus quite moderate, porrect, 
2nd joint shortly rough-scaled ; tongue developed ; antenna about 
one-half the length of wing, in both sexes nearly simple, minutely 
ciliated. Thorax nearly glabrous beneath ; femora glabrous ; fore¬ 
tibia with well-developed apical claw ; hindtibia not dilated, in both 
sexes with all spurs well developed. Abdomen rather short, 
moderately stout, the lateral tufts well developed. Wings not 
broad, their margins entire ; scaling smooth ; frenulum developed. 
Forewing with termen rounded, rather strongly oblique ; cell one- 
half ; SC“ anastomosing with SCh and then (shortly, or often at a 
mere point) with SC^'^ to form a double areole, of which both parts 
are ample; SC'* separating from SC^ shortly after SC^ ; K.^ short- 
stalked or (quite exceptionally), connate with SCH Hindwing
