Sept., I9II.] Smith: New Species of Xoctuid.^. 149 



6*. prccscs Grt. I have 4 c? and 3 ? of what may be considered the 

 more typical form, and two males of whose standing I am uncertain. 

 In this form the male antennae are serrate 'and bristled rather than 

 actually pectinated, and the head and collar are paler than the body 

 of the thorax. On the primaries the ordinary spots tend to become 

 confluent, and the s.t. line is well defined or even contrasting. There 

 is a tendency to a black filling between the ordinary spots; but how 

 far this goes, my series leaves me in doubt. 



Extends from Monterey, California, north to British Columbia. 



S. salcppa Smith. Agrees with prccscs in the paler head and col- 

 lar, but is otherwise amply distinct. It is a strigate, mottled form, 

 tending to become blotchy, and altogether different from the smooth 

 even markings of prccscs. My series at present contains 5 c? and 2 ?. 

 All my examples are from Wellington, British Columbia, and were 

 taken in April. 



Pleonectyptera serena, new species. 



Ground color ranges from pale or bluish ashen to reddish or yellowish 

 gray, the gray sometimes tending to drop out of the reddish or yellowish com- 

 bination. Primaries more or less powdery. Median lines incepted at costa 

 by more or less obvious black or blackish triangular spots. T.a. line nearly 

 upright, almost rigid, consisting of a rusty reddish or yellowish inner and a 

 smoky or blackish or black outer line. This is a variable feature, the line 

 being scarcely traceable in some examples, while in a very few, the blackish or 

 black portion only is obvious, usually more or less broken. T.p. line very 

 evenly and only a little bi-sinuate. sometimes broken or bent on the internal 

 vein. It consists of a rusty reddish or yellowish central line, inwardly 

 bordered by a narrow blackish or smoky line and outwardly by the darker s.t. 

 space more or less emphasized by smoky or black margining scales. This line 

 also varies, but is always conspicuously present and the pale included shade 

 is always one of the obvious features. The preceding shade line is a continu- 

 ation from the costal spot and is most often narrow, smoky and continuous : 

 it is rarely altogether absent, hut may be broken and sometimes is marked 

 with black scales, especially between veins i and 4 : in one example it is 

 almost continuously black. The s.t. line is rather irregularly and strongly 

 sinuate, making a rather small outcurve over veins 7-9 and another, much 

 better marked over veins 3 and 4, where small outward dents often break 

 into the terminal space. This line is usually marked by the difference be- 

 tween the dark subterminal and paler terminal space : sometimes it is an 

 almost continuous white line, sometimes it is broken into white dots and some- 

 times it is preceded by a distinct darker shade which may be emphasized by 

 black marks. There is a more or less obvious series of blackish terminal 

 lunules. The s.t. space is usually the darkest part of the wing ; but the shad-
