Moth, — Eight 3,2$. Anteuuxe not so broadly pectinated as in S, ipomece, and fore wings- 
squarish at the ai>ex, not produced as iu 8. ipomeiv^ the outer edge being much less oblique. Head 
and' thorax pale ash, with immerous pale greeu scales, giving the body (abdomen excepted) a 
slight siibolivaceous hue. The interantenual tuft ou the vertex of the head is edged witli black. 
Thorax with two blackish lines across the front, the hinder one sometimes much thebroadeiq hind 
edge of the tegular black-brown and hinder edge of the scntal region dark. 
Fore wings ash-gray, varied Avith whitish, reddish brown, yellowish green, and black markings. 
They are crossed by three well-marked lines. The basal line is black, curved outward on the 
costal region, and again ou the cubital vein; and within is a narrower parallel browu line. The 
base of the wing is whitish ash. Between the basal and median line is a transverse series of 
lunules, which are browu ou the costal region, the series consisting behind the subcostal vein of 
four reddish luuules; the row is much curved outward between the costa and internal vein. 
Beyond it is a narrow parallel hroAVii line. Between this and the basal line the wing is darker 
than elsewhere. A distinct black discal transverse streak, widest on the median line, where it 
ends. Between this and the middle line the wing is Avhite. A faint dift'use brown line just 
beyond the discal line, but the true extradiscal line is a series of reddish, couueeted patches or 
lunules, beginning on the subcostal vein and ending on the internal, the series being straight, 
not curved. Costa Avhite marked with black. A long black streak near the apex inside of the 
costa, and a similar streak in the first cubital interspace. In the succeeding space near the 
internal angle is a conspicuous white streak, Avithiu which is a black spot. Apical region whitish,, 
middle region of the outer fifth of the wing reddish, region of the iuterual angle brownish. 
Fringe ash, Avith dusky A^enular spots. 
Hind wings of 3 sordid Avhite,\^aryiugto dusky, Avith a whitish extradiscal broad diffuse line; a 
dusky patch ou the internal angle; in $ the wings are uniformly mouse-brown, with no distinct 
X)ale lines. Underside of fore wings uniformly mouse-brown, with four dark and five white spots 
on the outer third of the costa; hiud Avings iu the 3 AA^hitish, iu $ as ou the upper side. Abdomen 
forked at the end as usual. 
Plxpause of wings, 3 31-33 mui., $ 31-32 mm.; length of body, 3 15-17 mm., $ 15 mm. 
This is our commonest species of Schizura, and is easily recognized by its s(iuarish fore wings 
and by the Amriety of its markings iu Avhite, reddish, black, and browu, there being four cross 
lines ou the fore Aving, the middle and extradiscal being composed of reddish browu lunules; by 
the tAvo black subapical slashes, and by the white longitudinal vshort streak in the second cubital 
interspace, iu front of Avhich is a short, black streak, and within a black, roundish spot. 
Cwlodasys edmandsii Pack, is evidently a synonym of 8, unieornis. The specimen ( 3 ) marked 
ed7HandsU in xMr. Edwards’s collection appears to be only a small unicorma Avith narrower Aviugs 
than usual. The only difference is iu the dusky tawny costa of the tore wings and the similarly 
tiuted hind wings, due perhaps to imperfect preservation. 8, compeeta IT, Edw., one 3 type from 
California in American Museum of ]I:^atural History, New York, is only a climatic Amriety of 8. 
imicoriiis; the position of the markings is identical in the two forms, but conspecta is larger, the 
fore wings as much produced as iu any of unicornis. The pale area on the outer third of tlie wing 
is clear and Avhitish, and the hiud wings are clearer and Avhiter than iu any eastern examx)le ot
