252 REVISION OF MAMESTRA SMITH. 



specimens, hardly traceable. Claviforoi rather small, concolorous. 

 Orbicular small, oblique, slightly paler. Reniform small, upright, with 

 broad white annulus, somewhat constricted at middle. An indefinite 

 dark shade through median space. Secondaries smoky fuscous. Be- 

 neath, dusky with reddish powderings. Head and thorax concolorous 

 with primaries, the latter with tuftings distinct. Antennoe and genitalia 

 of male essentially as in sjiiculosa. 



Expands 25-27""". (1 to 1.08 inches). 



Habitat. — California, Oregon, Washington, Vancouver, Hudson's 

 Bay territory. 



Of the type iovm, ferrea Grt., seven specimens are in the collection : 

 California (C. V. R.) ; Washington, Vancouver (J. B. S.). 



Of the form cinnabarina Grt. there are nine specimens: California 

 (Meske, C. V. R.) ; Marin County (J. B. S.) ; Placer Countj', September; 

 Los Angeles County, October (through C. V. R.) ; Washington (Meske, 

 J. B. S.) — si)ecimens of each form labeled b}" Mr. Grote. 



This is rather a variable species in ground color, though the macula- 

 tion is constant and easily recognizable. The white ringed reuiform is 

 a conspicuous feature, and this species replaces renigera on the Pacific 

 coast. 



In the synonymy I have followed Butler, who makes his references 

 with the types under examination, an'i speaks positively. 



Mr. Grote says in the 111. Essay, 45: "The single specimens repre- 

 senting Celcena pii7ir.tif era, infecta, and egens are really so poor that I do 

 not think the species can be made out with satisfactory certainty." 



Mamestra spiculosa Grt. 

 1883. Grt., Can. Ent.,xv, 28; Mamestra. 



Somewhat luteous brown, all the lines distinct, paler. Median lines 

 geminate. Basal line present. Basal space evenly colored. T. a. line 

 evenly oblique, the defining lines narrow, dark, the included space pale. 

 T. p. line even, outwardly angulateover reniform. Median space some- 

 w'hat darker than base, the veins yellowish marked. Claviform dusky, 

 rather large in size. Ordinary spots concolorous, pale ringed. Orbicu- 

 lar rather large, oblique. Reuiform narrow, upright. Beyond the t. p. 

 line the s. t. space is pale, gradually becoming darker to outer margin. 

 S. t. line pale, distinct, sinuate, curved round the pale apical patch. A 

 row of black terminal lunules. Fringes pale lined at base. Second- 

 aries soiled whitish. Beneath, gray fuscous, powdery, a discal spot 

 on all wings. Head and thorax concolorous with primaries. The male 

 antenniB have the joints well defined, but hardly serrate. The geni- 

 talia are those of the group. 



Expands 25'""» (1 inch). 



Readily distinguished by the irregular ordinary spots and the pale 

 median lines. Its close connection with the others of this group is 

 marked by the identitj' of habitus and wing form.
