as in M. Oregonica. Secondaries with ground color sordid white; a 

 blackish basal shade, continued along abdominal margin; a large and 

 very strongly contrasted discal spot; and a sub-marginal band, nar- 

 rower than that of M. Oregonica, and more deeply sinuate a little way 

 from the apex. This band encloses a small sordid white blotch. Be- 

 neath, sordid white, with black, sub-marginal, slightly waved bands; 

 a very large black discal spot in primaries; a smaller one near the base; 

 and a large one also in secondaries. Thorax and abdomen concolorous. 



Exp. wings 25 mm. Length of body 13 mm.

Acopa pacifica, n. sp. — Primaries dark gray. The t. p. line only 

 slightly oblique, strongly black, with a slight tooth in the middle. 

 Basal half of line apparent; t. p. line oblique from near middle of internal 

 margin to a litUe below apex, where it is lost in a white cloud, which 

 passes directly along the wing from internal base to apex. Median 

 space shaded costally with white, darker on the internal margin. Reni- 

 form, sub-reniform and orbicular, very apparent, white, surrounded by 

 a black ring, and enclosing brownish scales. Sub-marginal space 

 clouded with brownish; a black streak at apex; and the marginal line 

 also black, equal. Fringes grayish brown. Secondaries dusky; fringe 

 white. Beneath, all the wings dusky, secondaries palest, with a trace 

 of a median band. There are also some white streaks about the costa. 

 Thorax concolorous with the primaries, with a large tuft at the base. 

 Abdomen and legs dusky.

Syneda perfecta, n. sp. — The primaries have the base fawn color, 

 the t. a. line being broadly brown. Behind this is a whitish band, 

 broadest on costa, and limited by the t. p. line, which is fawn color. The 

 space between it and sub-marginal line is shaded with brown, and almost 

 touching the costa is a white sub-oblong patch, with the edges dentate. 

 Sub-marginal band sinuo-dentate, pale. Behind this is a grayish band; 

 margin and fringe brown and white. Secondaries white at base, with a 

 linear discal mark, and a rose-colored stain from middle of wing to ex- 

 ternal margin. The border is broad, black, but interrupted in the middle 

 by a curved space, through which passes the rose-colored stain. The 

 black border is widest at apex. Beneath, both wings clear white, with 

 the black borders interrupted by sordid white blotches. Discal mark 

 on primaries prominent, joining the border. The rosy stain less dis- 

 tinct than above. Head and thorax pinkish drab above. Abdomen 

 ochraceous; all the body parts, beneath, clear white.
