T. a. line npriglit, lunate between the veins. T. j). line of the usual 

 shape. S. t. line very distinct, somewhat yellowish, inwardly margined 

 with rich, velvety brown, its course slightly sinuate. A row of lunate 

 terminal spots. Apex paler; terminal space dusky. Veins flecked with 

 white. Claviform of good size, broad, concolorous, outlined in black. 

 Orbicular somewhat paler than ground color, well sized, black mar- 

 gined, lleniform large, with a dusky shade; outwardly incomplete 

 and invaded by a yellowish or reddish shade which reaches to the pale 

 apical spot. Interiorly this pale shade is distinctly marked by a black 

 margin. Secondaries i)ure white, with a narrow, dusky, marginal line. 

 Beneath, pale, powdery, with common dusky line and discal spot, the 

 former iiH'omplete. Head and thorax concolorous dark gray, with black 

 irroration. The $ antenuiie are serrate and furnished with lateral tufts 

 of hair. Side pieces of ^ genitalia are rather suddenly and acutely nar- 

 rowed and curved toward the tip ; the clasper consists of a long, curved 

 corneous hook, attaining the end of side pieca. Expands 1.52-1.60 

 inches (;]8-40">™). 



Habitat. — Washington Territory, California. 



The variety is readily distinguished from the type form by the darker 

 color, the subapical pale shade, and the well marked s. t. line. It is 

 a tine form, and it was not without reluctance that I reached the con- 

 clusion that it was only a form of rtibrica, which has the habitus of a 

 Tceniocampa while subapicalis would hardly be referred anywhere but 

 to Mamestra. 



M. lepidula Smith, sp. uov. 



Primaries bright, somewhat ferruginous brown, darker in median and 

 terminal space. An oblique bright brown streak inferiorly in basal 

 space. Transverse lines distinct, single, margined with pale violet blue. 

 Basal line brown. S. t. line distinct, yellow, irregularly sinuate and 

 dentate ; apex of wing violet. Claviform small, pointed, velvety brown. 

 Orbicular oval or rounded, concolorous, defined and irrorate, with blue 

 scales. Reniform moderate, whitish, somewhat marked with brown 

 and irrorate with blue scales. Terminal space also more or less irrorate 

 with blue scales. Secondaries of $ white, of 9 dusky. Beneath j»ale, 

 with yellowish irroration and common external line. Head and thorax 

 concolorous with primaries. Abdomen fusco-luteous with distinct dor- 

 sal tufts ; that on fourth segment most prominent. Antennae of $ 

 distinctly serrate, the serrations bristled. The side piece of $ is mod- 

 erate, but little dilated at tip, and rounded. The clasper is simple, 

 stout, rather short, curved, and somewhat irregularly enlarged at tip. 

 Expands 1 inch (25'"'").

This is one of the prettiest of our species ; its bright colors, rhe bluish 

 transverse lines, yellow s. t. line, and pale reniform rendering it easily 

 recognizable. The fringes to primaries are long, even, cut with obscure 

 violet. It is utterly unlike any other species with serrate antennae.
