specimens. Fringes dark, pale cut on the veins. A black longitudinal 
basal line and one along inner margin. Claviform large, concolorous, 
faintly outlined; beyond it a blackish patch to the t. p. line, which in 
pale specimens is often the most prominent feature of the wing. Or- 
bicular large, oblong or oval, oblique, concolorous, variably outlined, 
closely approaching, but not in any specimen seen by me confluent 
with the largereniform. This latter isalso concolorous, kidney-shaped, 
more or less completely outlined. There is usually an obvious dusky 
shade between these spots. Secondaries whitish to fuscous, with soiled 
or brownish outer margins, a darker lineat base of fringes. Beneath, 
whitish, powdery, with a blackish outer line and distinct discal spot on 
all wings. 
Expands 32 to 35 millimeters; 1.28 to 1.40 inches. 
Hapirat: Middle, Southern, and Central States; Texas (Belfrage), 
March 10 to April 2; central Missouri March 25, April 9 and 19. 
This insect varies quite strongly in ground color, dark specimens, 
| lacking the pale extra linear shade, being sometimes mixed with con- 
| fusa. The black patch beyond the claviform is quite characteristic and 
is obvious in all the specimens I have seen. In the male, of course, no 
mixture is possible if the antenne are referred to. In the female, the 
fused ordinary spots will generally separate confusa. 
Ten specimens (Texas and central Missouri, collection of C. V. R. 
and J. B. 8.), are in the National Museum collection, and from the dates 
| given itis an “early bird.” The male characters are much as in con- 
| fusa, but the tip of harpes is more rounded, the upper angle pointed, infe- 
rior obtuse, the margin set with spinulesits fulllength. The clasper is 
double, consisting of a moderately long, curved hook, with an obtusely 
|| pointed tip, aud a very short, weak curved spur at the base of the 
longer process. 
The species seems not rare in Texas, and the paler form is there mest 
common. 
Morrisonia rileyana Smith. 
1890. Smith, Ent. Amer. vi, 212, Morrisonia. 
Head, thorax, and primaries, in ground color, grayish white, with a 
‘ferruginous tinge. Palpi with a strong admixture of brown scales in 
their clothing. A rusty red brown line crosses the front below the an- 
tenne. Collar tipped with powdery black. Patagize black, powdery. 
|| Thoracie tufts tipped with rusty. Primaries with a broad, black, longi- 
tudinal shade, running beneath the median vein to t. p. line, then 
| broadening to outer margin, which it reaches below the apex. Along 
the inner margin an irregular, narrow, whitish border only is left. A 
‘ferruginous spot is in this black shade in the terminal space. Above 
this black shade the cell is filled with a rusty wash, in which the reni- 
form is very faintly outlined by a narrow ring of ground color. TT. a. 
‘line geminate, vague, diffuse; traceable in costal region only. 'T. p.
