Grote’s meagre description would apply equally well to both species 
under discussion we are of the opinion that it would be well to regard 
the specimen so labelled in the British Museum as the authentic type. 
The true auranticolor may be separated from the spurious one by its 
shorter chunkier primaries and its rather brighter and more variegated 
appearance; the t. a. line is less dentate, the t. p. line is not concave 
in the fold but either straight or rather convex and edged inwardly 
with black at this point, and the s. t. space is not crossed between veins 
1 and 2 by a dark shade. There is a long series in Coll. Barnes from 
Truckee, Calif., which agrees with auranticolor type; the locality is 
rather far removed, but there seems not much doubt as to the identity. 
Auranticolor is very close to barnesi Sm., the markings being prac- 
tically identical and it is even possible that the original series included 
some auranticolor. In view of this fact we would restrict the name 
barnesi to those specimens from Yellowstone Park, Wyo., which are 
characterized by their general yellow-brown appearance ; two co-types 
from this locality are in Coll. Barnes and one was figured in “Contri- 
butions” Vol. II, No. 1, Pl. 17, fig. 2. For the species commonly 
labelled auranticolor in collections and which is now apparently with- 
out a name, we would propose the name GROTEI and have labelled as 
type the 2 specimen figured in our “Contributions” Vol. II, pt. 1, 
Pl. XV, fig. 7 from White Mts., Arizona. This species extends from 
Colorado southward through New Mexico and Arizona. 
TRACHEA FUMEOLA Hamp. (syn. T. probata B. & McD.) 
Hampson figures a California ° which is not the same species as 
the ¢ type from Arizona, this latter proving to be identical with what 
we described later, misled by the erroneous figure, as probata. 
TRACHEA MODIOLA Grt. (syn. Trachea mactatoides B. & McD.) 
It is probable that Trachea mactatoides B. & McD. will prove a 
synonym of this species; the type localities of the two species are 
respectively Wisconsin and Arizona but from what we have seen of 
other material of Grote’s bearing the same locality label we have 
doubts as to the authenticity of this locality, (see our remarks under 
Ozarba aeria Grt.). Several species attributed by Grote to Racine, 
Wis. appear to have been originally collected in southern localities.
