obvious on the incurve and at the inner niarfiiji. S. t. line marked only hy the 
difl'erence in shade between terminal and s. t. space. This difference is very 
strongly marked at the costa, then the s. t. space is almost divided by the white, 
and thence the dark color again widens with an outward curve the division not 
sharjily marked. A row of black terminal dots. Base of fringes olivaceous. 
Eeniform upright, dark, constricted inferiorly, black marked, and more dilated 
than superiorly ; no trace of orbicular. Secondaries white, with a dusky discal 
•spot and indefinite outer border, in which is an ovate white spot. Beneath white, 
with the maculation of the upper side faintly reproduced. Expands 1.04 inches; 
26 mm. 
Hab . — Colorado (Bruce). 
Tills is a close ally of <S'. vanella, which it resembles completely in 
habitus and structure. It differs obviously in the entire lack of the 
orbicular and claviform in the much smaller reniform and in a gen- 
eral softness of tint and maculation not noted in its eastern congener. 
The type is from Mr. Neumoegen’s collection, and there are three 
handsome examples in the collection U. S. Nat. INIuseum, all of Mr. 
Bruce’s collecting. 
biciispida n. sp. — Head, thorax and primaries luteous. Prima- 
ries with maculation darker, more olivaceous, and with an admixture of black i.sh 
scales. The transverse lines are all of the palest shade of the ground color, and 
defined by the difference in shade between tbe adjoining spaces. T. a. line with 
a long outward cusp on the median vein, and a deep incurve below the internal 
vein. Basal space dark, with a pale cusp on the costa, and with a strong admix- 
ture of black scales along inner margin, tbe internal vein pale. S. t. line regu- 
larly bisinuate, even, oblique, well defined tbroughout. S. t. space quite strongly 
speckled with black scales, especially along the outer margin defining the s. t. 
line. This latter is deeply and suddenly incurved opposite the cell, then ap- 
proaches quite close to the outer margin, again indented nearly opposite the anal 
angle. A row of small blackish terminal spots, from which proceed blackish 
shades cutting the fringes. Orbicular wanting. Reniform moderate, blackish, 
quite indefinite; median s])ace crossed by a diffuse dusky shade, faint through 
the centre, but spreading out and occupying nearly the entire width of the me- 
dian space inferiorly. Secondaries black, with a broad yellow median band, 
divided by a large black discal spot; fringes yellow. Beneath, primaries pale 
yellow, with a broad basal shade, a large discal spot, and a broad subterminal 
baud black ; secondaries white, with an incomplete outer band and discal lunule 
black. Expands .96 inch. ; 24 mm. 
Hub . — Southern Texas. 
The anterior tibia has two stout inner and five stout outer claws, 
and it is therefore related to pucku7'dii, morhia and nobills. From 
all of these it difiers in the course of the transverse lines, and the 
more decided contrasts in maculation. A single specimen from Mr. 
Neumoegen’s collection is before me.
