1862 BUTTERFLIES BEYOND NEW ENGLAND. 



sifted, the transverse, light colored baud being indicated only by the dark and obscured 

 edgings ; and the upper surface of the fore wings shows on the costal margin a large, 

 blackish brown, longitudinal bar on a line with and as large as the extra-mesial, tawny 

 baud. 



Very little is known of this butterfly, which has been taken only in 

 West Virginia and Colorado.

Imago. Head tufted above witli dull olivaceous and black hairs, the apical joint of 

 the palpi black, the under surface of the palpi pallid ; antennae black, heavily flecked 

 beneath witli white, excepting at the naked tip of the club, which is more or less en- 

 livened with castaueous. Thorax covered above with dull gray, olivaceous hairs, 

 beneath with dull, silvery white scales and whitish hairs; the legs clay browu. 



Wings above rather dark slate brown, varying in depth of tint, and with glossy re- 

 flections. Fore wings usually marked with pallid, occasionally with lawny spots, of 

 which there is a pair of confluent ones marking the extremity of the cell, and an extra- 

 mesial series of spots foi'ming a very irregular, oblique, subcontiuuous baud; it is 

 composed of three elongated spots in the suljcostal interspace, midway between the 

 tip of the cell and the wing ; a pair of suljquadrate spots in the interspaces beyond the 

 cell whose inner border is on a line with the outer border of the neighboring spots, and, 

 obliquely continuous with these, three very unequal spots in the median and medio-sub- 

 median interspaces, that in the lower median interspace generally the largest, that in 

 the medio-submedian very variable and more frequently fulvous to a greater or less 

 extent, occupying the middle of the interspace ; these spots, especially the latter ones, 

 are most conspicuous in the female; in the male they are usually much reduced in size 

 and those in the lower median and medio-submedian interspaces are subobsoleteandiu 

 part obscured by the fulvous tone of all that portion of the wing which follows the 

 discal stigma ; this is composed very much as in its ally E. metea. Hind wings more or 

 less suffused with pale tawny, more conspicuous in certain lights than in others, 

 marked at the tip of the cell and crossed by an extra-mesial series of subcontiuuous 

 pallid spots, generally more or less tawny, which are the vague repetition of the more 

 distinct spots of the under surface; fringe of all the wings sordid white, often 

 more or less infuscated in the upper half of the fore wings and preceded by a thread of 

 blackish brown. 



Beneath, dull, dirty, olivaceous brown, a deeper olivaceous browu bordering all the 

 markings, especially on the hind wings, and lending them greater perspicuity. The 

 fore wings show in both sexes the markings of the upper surface of the female, but 

 they are perhaps more conspicuously continuous, and terminate on the inner border iu 

 a large, vague, triangular, pallid spot; these show also a slight tendency to follow as 

 threads down the nervures, and occasionally the outer half of the wing apart from 

 them is heavily flecked with saffron scales. On the Imid iiniigs the extra-mesial Ijaud is 

 very marked and almost invariably continuous, forming a bent band, bent at somewhat 

 ess than a right angle, composed of subquadrate spots, produced at all the augles 

 along the nervure tips, and margined, externally at least, with dark brown, the upper
