82 REVISION OF XYLOMIGES AND MORRISONIA—SMITH. 
line geminate at inception, very oblique outwardly through costal — 
region, becoming punctiform below and traceable through the black — 
shade by pale venular dots. Secondaries white basally, with a broad — 
powdery black margin outwardly ; a vague discal lunule, an outer line — 
of venular dots and a black, interrupted terminal line. Beneath white, 
with ferruginous, and a sparse black powdering; a common punctiform } 
outer line, and a black discal spot, most distinct on secondaries. . 
Expands 31 millimetres ; 1.25 inches. 
Hapirar: Florida; Texas, March 27, Central Missouri, April 21. 
Two specimens are in the Museum collection (C. V. R.), another from 
Florida, is with Mrs. Slosson. The species is the smallest of those re- 
ferred here, and has a casual resemblance to Homohadena. 
In genital structure this species is like mucens, in the form of the 
harpes as well as of the claspers. 
Morrisonia bisulca Grt. 
1881. Grt., Can. Ent. x1, 230, Mamestra. 
Ground color fuscous brown. Collar tipped by hoary seales.  Pri- 
maries with whitish gray powderings along the costal and inner mar- 
gins, most distinct in each case between the median lines, which are 
here visible. The veins are black lined, less obviously so on the costal 
series. Median lines obvious only on the costa and inner margin as gem- 
inate marks. The t. a. line is traceable for part of its course, indicating 
that it is strongly angulated. ‘T. p. line but vaguely indicated near 
inner margin, outwardly produced on the veins. S. t. line consisting 
of a series of black spots in the interspaces, those between 2 and 3, 4 
and 5, and 5 and 6, sending a shade inwardly across the s. t. space. 
A series of whitish dots at base of fringes, sending out a pale ray 
across the otherwise dark fringes. Veins 4 and 5, and less markedly 6 © 
and 7, are accompanied by pale shades, extending through the terminal ~ 
space. A prominent black basal dash through submedian interspace, 
having the claviform attached, and usually extending beyond it to the 
t. p. line. Orbicular elongate, narrowed, concolorous, outlined in black, 
the black lines uniting beyond the spot, forming a shade and again 
separating in forming the inner margin of the small upright reniform. 
This latter is outwardly indefinite, and is marked with white spots, dis- 
tinct in all specimens I have seen. Secondaries pale whitish fuscous, 
with pale tipped fringes. 
Expands 34 to 36 millimetres=1.36 to 1.48 inches. 
HABITAT: Arizona. , 
A specimen of this species is among the unnamed material in the 
collection U.S. National Museum. The sexual characters are unique 
for the genus. The harpes are very slightly curved, and taper quite 
regularly to a somewhat obtuse tip, which is not spined or armed in 
any way. The clasper is a single, iong, curved, corneous hook, with its 
broad and flattened base quite close to the base of the harpe.
