merited as in the common alia Guen. Abdomen of the same color, un- 

 tufted. Wings slightly more elongate than in alia. Anterior wings 

 uniform gray, with scattered yellow atoms, particularly on the basal 

 and terminal spaces, but without brown or reddish admixture. Veins 

 very prominent, but not disconcolorous. The ordinary lines black. 

 Half-line present. The interior line extends obliquely from the costa 

 to the submedian fold, where it connects with a black, curved, longi- 

 tudinal branch from the base. At this point the claviform spot is indi- 

 cated as a blackish shade attached to the line; below, the interior line 

 extends directly to the inner margin. Median shade indistinct and 

 suffused. Ordinary spots large, whitish, and contrasting, with central 

 gray shades. Orbicular spot circular, resting on the median vein. 

 Reniform spot slightly excavated on each side, its base touching the 

 simple, blackish, exterior line. The latter is of the usual shape, 

 formed of internervular lunules. The subterminal line is faint, 

 whitish, preceded by very faint, black, cuneiform marks. A row of 

 black spots at the base of the fringe. Posterior wings light grayish 

 fuscous, with a median band and discal dots. Wings beneath with a 

 common line. The anteriors have the costal portions of the median 

 and basal spaces covered with long close-lying hair. Posteriors with 

 discal dot. 



Hab. California. 



Prof. C. Y. Riley, of St. Louis, kindly presented me with this spe- 

 cies, with permission to describe if found to be new. It can be easily 

 determined by the cuneiform, subterminal series of spots, and the 

 whitish orbicular and reniform spots. 



M. Guenee has published in the " Species General " (Vol .v, pp. 355 

 and 356) two species of Tamiocampa, which have not yet been iden- 

 tified, founded on unpublished drawings of Abbot's. 



It seems to me that to recognize these species, styracis and hibisci, 

 and others of various genera described by M. Guenee in the same 

 way, will establish a precedent which will cause much, confusion. I 

 simply raise the question for discussion, leaving it to be decided by 

 others. 



Tseniocampa confluens nov. sp. 



Expanse 34 mm. Length of body 13 mm. 



Eyes hairy. Thoracic villosity as usual in the genus. The anterior 

 wings are brownish-cinereous, the brown tint more apparent near the 

 spots; otherwise uniformly diffused over the wings. The interior line 

 is obsolete, only represented by a faint shade on the costa. The
