NORTH AMKRIGAN LEPIDOPTKRA. 65 



Fringes hrowii witli a faint line at base, T. a. line white, marking the anterior 

 margin of the dark median space, outwardly angnlated in the cell and reaching 

 the orbicular, which is oval, elongate and pale powdered, T. p. line white, 

 forming the outer or posterior margin of the dark median space; stronglj' and 

 somewhat acutely exserted over the cell and almost rigidly oblique below. The 

 reuiform is upright, narrow, annulate with gra.v. slightly paler in shade. S. t. 

 line wanting. Secondaries yellowish fuscous, with the outer margin darker, 

 more smoky and the fringe paler. Beneath rather gray, finely powdered, im- 

 maculate; secondaries rather paler, the powderings coarser. Expands 2S mm. ; 

 1.12 inches. 



Hub. — Colorado (Bruce) ; N. W, British Coliiii)bi;v, Neumoegen. 



Two specimens have been examined, one of them in Mr, Neumoe- 

 gen' s collection, the other from Mr. Bruce, now in the U. S. National 

 Museum. The species is a very distinct one, and is allied to atrifas- 

 ciata Morrison. It h:is a resemhlance in color and ornamei;tation 

 to Plufila parilis, and should be easily recognizable. 



OncociieiliiM relecta n. sp. (PI. vi, fig, 11)— Ground color a pale mouse- 

 gray, powdery. Head with front paler, a deep chestnut-brown line between the 

 antennre, else concolorous. Thorax concolorons, immaculate. Primaries uniform 

 in color to the subterminal space, beyond which it darkens to a deeper brown, 

 extending to the outer margin, and involving also the fringes. Basal half line 

 single, not extended beyond the costal region, T. a, line simple, broad, distinct, 

 black, slightly outcurved, even, T. p. line simple, black, evenly outcurved over 

 the reniform, thence slightly irregular to the hind margin. The s. t. line is not 

 traceabl,3 through the dark terminal space. A series of dark terminal lunules. 

 Secondaries white at base, with a broad black outer margin, fairly well defined 

 inwardly, the veins dusky. Beneath both wings whitsh, with a blackish outer 

 margin, powdery. Expands 31 mm. ; 1.24 inches, 



Hab. — Colorado ; Bruce, No. 483. 



A single male specimen only is before me, and I believe that Mr. 

 Bruce took no others. The species is very simply marked, and 

 should be easily recognized. Tt has a decided resemblance to the 

 species of Ilomoluideaa at first sight, from the simple transverse lines, 

 and it has no very close allies in the genus to which I have referred 

 it, though it has all the characters of a typical Oncocucinis. It is 

 best referred to the section homorjeiut, though it has some resemblance 

 to terminalis. There is no trace of the ordinary spots in the sj)eei- 

 men before me; but I would not be surprised if they pr;)ved visible 

 in other specimens when a larger material is at hand. 



While this specimen has not any relative among the described 

 species, it is certain that there are others as yet undescribed that will 

 at some time in the future keep it company. I have a very poor 

 specimen from the Colorado desert, given me by the late Henry
