thickened, upper margin of side piece serving the same purpose. Ex- 

 pands 1.10 inches (28 mm ). 



Habitat. — Maine (Kittery Point). 



Easily recognized by the distiuct round orbicular. The frontal vesti- 

 ture is rather coarse, scaly, and there is a distinct divided tuft behind 

 collar. This species is closely allied to Mamestra, with the balance of 

 characters in favor of Tceniocampa. 



Taeniocampa uniformis Smith. 

 Proc. U. S. Nat. Mus., 1837, x, 472. 



Rather dark mouse gray, powdery ; median lines obsolete, barely 

 traceable. T. p. line marked by a row of venular dots. S. t. line 

 slightly sinuate, concolorous, marked by the somewhat darker terminal 

 space and a preceding dusky shade. Reniform marked by a dusky 

 patch, orbicular wanting. Secondaries soiled white, outwardly darker, 

 an indistinct discal lunule. Beneath with incomplete outer line, a dis- 

 tinct discal lunule. Head and thorax concolorous, with primaries. 

 The harpes have the superior margin thickened, corneous, obtusely 

 produced at the angle of bend, and forming the clasper. The tip is 

 somewhat dilated and densely spiuulose at inner side. Expands 1 

 inch (25 m,1 M. 



Habitat. — Arizona. 



Closely related to peredia, but sufficiently distinct by the dark color, 

 obsolete maculation and small size. In this species the clasper is not 

 separate, but formed of the superior margin of side piece, which is 

 thickened. There is an indistinct thoracic tuft behind collar. 



Taeniocampa Columbia Smith. 

 Proc. U. S. Nat, Mus., 1887, x, 472. 



Luteous reddish, powdery, terminal space somewhat darker, veins 

 slightly darker. Median lines single, obsolete or but little darker. 

 T. a. outwardly arcuate, inwardly toothed on vein 1. T. p. line par- 

 allel with outer margin. S. t. line slightly paler, defined principally 

 by the slightly darker terminal space. Ordinary spots obsolete, or 

 very faintly traceable, the reniform marked by a slightly darker infe- 

 rior shade. Secondaries dirty fuscous, paler toward base. Beneath 

 rusty, powdery, with a common outer line. Antenna; of male serrate 

 and bristled. Head and thorax concolorous. Harpes of male narrow- 

 ing beyond middle, somewhat dilated at tip, and inwardly fringed with 

 spines. Toward base is a stout, strong corneous hook, which is ob- 

 tusely terminated. Near to tip is another, slender, semi-membraneous 

 and but slightly curved hook. Expands 1.15 to 1.25 inches (29 to 31"""). 



Habitat. — Northwestern British Columbia. 



This species is one of those collected by Captain Geddes in 1884, and 

 the types, male and female, are in Mr. Neuuioegen's collection. It is
