the type of densa Wlk. As it now stands the synonymy of the genus 
is as follows: 
ArzaMA WIlk. (Sphida Gtt.) 
obliqua Wlk. (syn. obliquata G. & R.) 
densa WIk. (syn. oecogenes Dyar) 
gargantua Dyar. 
anoa Dyar. 
OZARBA AERIA Grt. 
The species reported by us as O. fannia Druce (Can. Ent. 45, 184) 
proves to be aeria Grt.; fannia must therefore be removed from our 
N. American lists ; the locality “Wisconsin” as given by Grote is prob- 
ably an error as our series of specimens comes from Southern Texas ; 
Dr. Hoy of Racine, Wis., from whom Grote received various speci- 
mens, does not appear to have attached much importance to locality 
labels, and Grote has simply attributed all the material to Wisconsin. 
EUSTROTIA ORTHOZONA Hamp. (syn. E. santa rita Dyar) 
Dr. Dyar has misidentified Hampson’s species, evidently consider- 
ing it to be the form with a tooth about the centre of the inner edge 
of the black median band. As a matter of fact this edge in both types 
is almost straight; the toothed form is probably the more normal form 
of antonita Dyar, which was described from a single specimen received 
from Dr. Barnes in which the median band is broken. Dr. Dyar 
would do well to follow his own advice to us and avail himself of the 
resources of the various European and American museums before 
appearing in print with needless synonyms. 
GRAEPERIA NUICOLA Sm. (syn. G. carcharodonta Hamp.) 
In his revision Smith appears to have overlooked the peculiar 
frontal prominence of both this species and meskei Sm., this latter 
species being apparently merely a slight variety of nuicola; the types 
of both species in the National Museum show this structure, nuicola 
being identical with the species described later by Hampson as car- 
charodonta. 
GRAEPERIA ALTERA Sm. (syn. conocharodes Hamp.) 
Smith’s species had been misidentified in the British Museum thus 
leading to the above synonymy.
