Ko. 1283. REVISION OF SOME NOCTUID MOTHS— SMITH. 183 



the transverse posterior line are usually traceable, never prominent, 

 and often entirely absent. Secondaries yellowish in tinge, ranging to 

 a transparent smoky, the disk being always a little darker. Beneath 

 much paler than above; primaries with the disk variably blackish, 

 ranging from a little shading over the cell to nearly the entire surface. 

 Secondaries more or less powdery along the costa, and a little on the 

 outer margin, with a small discal dot on a majority of the specimens 

 before me. 



Exjpanse. — 1.25 to 1.40 inches (31 to 35 mm.). 



Habitat. — Sierra Nevada, California (Hy. Edwards); Salt Lake, 

 Utah (Hy. Edwards); Utah in July (Poling); Denver, Colorado, June 

 10 (Oslar); Glenwood Springs, Colorado, June 2-1:, July 10, 16, and 

 August 24 (Barnes). 



Eleven examples are before me, and they vary little except in the 

 depth of the red tinge and in the amount of black on the secondaries. 

 On the underside there is the usual range of variation as to area 

 covered by black shadings and powderings, but nothing else. 



The average size of the specimens is 1.30 inches, three examples — 

 females — exceeding that materially, while only tw^o fall much below it.

" Eyes hairy. Head and thorax concolorous with the anterior wings. 

 The latter are uniform 3^ellowish salmon color, interrupted only by 

 the median vein, which is white, as well as its second and third 

 branches; the apical costal branches are also whitish. Posterior wings 

 and under surface white, immaculate." 



Expanse. — 34 mm. Length of body, 16 mm.

I have already recorded my convictions as to this species; but give 

 the above copy of the original description, since, after all, the insect 

 may be American, though not, I am convinced, a native of Pennsyl- 

 vania. 



It is obviously a member of this group and quite out of the range 

 of variation for luteopallens. The primaries are like ruhripallens, but 

 the white secondaries and underside bar it. If the same form does 

 ever again turn up, there will be no difficulty in recognizing it.
