female, but is inconstant in size of wing. One specimen of Consobrhia 

 is in this respect smaller than Smithii. As to the difference in 

 shadings it appears to me quite unimportant and not unlikely a variable 

 character. 



3. Similis, Guen. Sp. Gen. VII., 267, 1852. Ophiusa. 



" 40 mil. Wings entire, powdery, of an even violaceous ashen, shaded 

 here and there with reddish ; with the two median lines hardly visible, 

 very fine and, between them, another similar line bent in an opposite 

 direction to the t. p. line and nearly touching the latter at either extremity, 

 the whole hardly distinct. A black apical mark, composed of two little 

 triangles united at apices, a little shaded interiorly. Hind wings light 

 brown, with the fringes ashen. Beneath of the same brown, with indistinct 

 line and lunule. 



Var. Apicalis, id. The arcuate median line largely shaded with 

 blackish exteriorly.'' 



This species is unknown to me. It cannot be the succeeding form 

 owing to the given colour, the triangulate apical spots, and the arcuate 

 median line. 



4. Concolor, n. s. 



$ Entirely of a light chocolate brown. The forewings unicolorous, 

 with a slight frosty violet reflection, without any perceptible markings or 

 any darker shadings, except the liturate dark brown apical mark, which 

 is oblique, of nearly uniform width and subcontinuous. Hind wings 

 plain brown, the outer edge and fringes very slightly shaded with ashen. 

 Beneath paler, concolorous yellowish-brown, with faint traces of one or 

 more common lines and discal dots. Palpi slightly exceeding the front. 

 Antennte simple, the joints beneath with short hairs. One specimen, ex- 

 panding 42 mil., in Mus. Brem. 



9 Somewhat darker than the male. The frosty violaceous shade 

 obtains strongly over basal half of primaries and allows an uneven darker 

 t. a. line to be faintly visible. At the centre of the wing, in the place of 

 the median shade, is a straight sharp line of demarcation, beyond which 

 the wing is outwardly diffusedly much darker shaded, the dark colour 

 fading to the fringes and allowing the apical mark to be plainly visible. 

 In one specimen the apical mark is apparently linear and dislocated in-
