Moth. — Eight S,2 9 . AntenuiB not so broadly pectitiated as in S.,i2)omea', and fore wings 

 squarish at the apex, not produced as in S. Ipomea', the outer edge being niucli h^ss oblique. Head 

 and thorax \ii\\e ash, with numerous pale green scales, giving the body (abdotneu excepted) a 

 slight subolivaceous hue. The iuteranteiinal tuft oti the vertex of the head is edged with black. 

 Thorax with two blackish Hues across the front, the hinder one sometimes much the broader; hind 

 edge of the teguhe black-brown and hinder edge of the scutal region dark. 



Fore wings ash-gray, varied with whitish, reddish brown, yellowish green, and black markings. 

 They are crossed by three well marked lines. The basal Hue is black, curved outward on the 

 costal region, and again on the cubital vein; and within is a narrower parallel brown line. The 

 base of the wing is whitish ash. Between the basal and median line is a transverse series of 

 lunules, which are brown on the costal region, the series consisting behind the subcostal vein of 

 foiu- reddish lunules; the row is much curved outward between the costa and internal vein. 

 Beyond it is a narrow parallel brown line. Between this and the basal line the wing is darker 

 than elsewhere. A distinct black discal transver.se streak, widest on the median line, where it 

 ends. J'.etween this and the middle line the wing is white. A faint dilfuse brown liiu! just 

 beyoml the discal line, but the true extradiscal line is a series of reddish, connected patches or 

 lunules, beginning on the subcostal vein aiul ending on the interiml, the series being straight, 

 not curved. Costa white 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, withiu which is a black si>ot. Apical region whitish, 

 mi(hlle region of the outer fifth of the wing reddish, region of the internal angle brownish. 

 Fringe ash, with dusky venular spots. 



Iliml wings of i sordid white, varying to dusky, with a whitish extradiscal broad diffuse line; a 

 dusky patch on the internal angle; in 9 the wings are uniformly mouse brown, with no distinct 

 j)alc lines. Underside of fore wings uiuformly mouse-brown, with four dark ami live white spots 

 on the outer third of the costa; hind wings in the S whitish, in 9 as on the upper side. Ab(h)meu 

 forked at the end as usuiil. 



I'ixpanse of wings, <5 31-33 mm., 9 31-3li mm.; length of body, i i.j-17 mm., 9 15 mm. 



This is our commonest species of Schizura, and is easily recognized by its squarish fore wings, 

 and by the variety of its nnirkings in white, reddish, black, and brown, there being four cross 

 lines on the fore wing, the middle aiul extradiscal being comi)osed of reddish brown lunules; by 

 the two black subapical slashes, and by the white longitudinal short streak ifi the se(u)nd cubital 

 interspace, in front of which is a, short, black streak, and within a black, rouiKlisli sjjot. 



Cicloddsys ('(biuiiKhit Pack, is evidently a synonym of <S'. Hnic(yriiis. Tiie specimen ( S ) marked 

 edmandnii in .Mr. Edwards's collectioti appears to be only a small unicornis with narrower wings 

 than usiml. The only difference is in the dusky tawny costa of the fore wings and the similarly 

 tinted hind wings, due jn'ihaps to imperfect preservation. S. couspicta II. Kdw., one c5 type from 

 California in American Museum of Natural Uistory, New York, is only a clinnitic variety of IS. 

 unicornis; the jwsition of the markings is identical in the two forms, but eo?(.y>*'c?rt is larger, the 

 fore wings as nuich prodtn^ed as in any of unicornis. The i)ale area on the outer third of the wing 

 is clear and whitish, and the hind wings are clearer and whiter than in any eastern example of
