Edwards, which resembles refeda very closely, but is distinct. It is 

 altogether too poor to describe, and will keep until better material 

 is at hand. 



OncociieiiiiM viriililiiicta n. sp. (PI. vi, fip;. 12)— Ground color dull lu- 

 teous, with a distinct olivaceous tinge. Head darker, smoky. Collar with a 

 strong admixture of black and white scales, forming a whitish tip. Disc of 

 thorax also powdered with white scales, though much less prominently so. Pri- 

 maries rather even in color, all the noi-mal maculatiou traceable, though not 

 prominent. Basal line simple, black, distinct. T. a. line black, distinct, a little 

 ol)lique outwardly, aiid somewhat irregular, preceded by a few white scales. T. 

 p. line crenulated, blackish, with a rather even outcurve, followed by an indefi- 

 nite pale shade. S. t. line very irregular, marked by white scales, which are 

 preceded by a few blackish scales ; interrupted, except toward the apex. A series 

 of small blackish lunules at the base of the fringes. The latter are pale, cut 

 with dusky, and there is a dusky line at the base. There is a somewhat faint 

 and irregular median line touching the reniform in its course. Claviform very 

 small, defined by black and centered by white scales. Orbicular white, con- 

 trasting, defined by black scales, round. Reniform rather small, lunate, white, 

 centered by the ground color. On the costa there is a series of white dots mark- 

 ing the inception of all the transverse lines. Secondaries smoky brown, with a 

 blackish extra median line, and a broad but not contrasting blackish outer mar- 

 gin. Fringes white, with a dusky line at the base. Beneath, primaries smoky, 

 powdery toward the costa. Secondaries powdery gray, with a dusky extra- 

 median line and a blackish outer margin. Expands 30 ram. : 1.20 inches. 



Hub. — McLean, British Columbia ; Bean, No. 3676. 



A single specimen only of this very distinct species is at hand, 

 and according to Mr. Bean no others were taken. The example is 

 a female in good condition, and has a resemblance to the variolata 

 group of the genus Mamedra. It has no very close allies in the 

 genus to which I have referred it, and therefore finds a place in the 

 group Jwmogena, to which all such species are assigned. The olive 

 tinged primaries, and the contrasting white ordinary spots will serve 

 to distinguish the species, once the genus is recognized. 



Since the above was sent to the printer I have received a specimen 

 from Mr. J. Alston Moffat, who informs me that he captured alto- 

 gether four specimens near Hamilton, Ontario, many years ago, late 

 in Summer, on golden-rod. His specimens had lost nearly all trace 

 of the mossy-green appearance. 



Oiicociieinis coI<n*a«lo n. sp. (PI. ii, fig. 5) — Head, thorax and primaries 

 a bluish ashen gray. Head with a blackish fuscous transverse band on front and 

 an admixture of scales of the same color on the vertex. Collar with a blackish 

 band at base and a narrow fuscous band near tip. Thoi'acic disc with black 

 scales intermixed. Primaries sparsely powdered with black and fuscous scales, 

 an in<lefinite fuscous shade extending through the centre of the wing. T. a. line
