and the margiii ; occasionally, though but very seldom, the outer half 

 of the wing is uniformly marbled throughout, and in some individuals 

 the whole wing is covered with nearly uniform marbling, or is so ob- 

 scured by blackish that the markings as here described are iudistin- 

 guisliable, and in such cases the under surface of the secondaries can- 

 not be distinguished from similar cases in C. Otno; the nervures are 

 not flecked with white.

(Harris remarks in his Injurious Insects, p. 304, that " it has also been 

 seen on the Monadnock Mountain, and will probably be discovered on 

 the tops of high mountains in our own State, if looked for at the proper 

 season." Some other Satyrid must have been mistaken for this by the 

 observer on Mt. Monadnock, I am very sure, though that mountain, 

 with its barren summit, would be more favorable for its habitation than 

 any in our own State, for the highest of these not only is wooded to the 

 summit, but I have ascended it many times at all seasons of the year, 

 on entomological excursions, without meeting with this butterfly.) 



The first description and figure of this species was that given by Say 

 in his American Entomology, plate 50. In this figure the secondaries 

 are represented broader than in nature, and in the coloring it is not 

 very accurate; the upper surface is not dark enough, and should not 

 have the nervures so reddish as given there ; the under surface of the 

 secondaries never has so marked an infusion of ochraceous colors in the 

 outer half, and when it is at all conspicuously present, it also exhibits 

 it somewhat on the basal half; the character also of the markings on 

 the basal half is an unusual one, not representing the norm. 



The plate given in the republication of this work, with his other 

 writings collected by Dr. LeConte, is one which was re-engraved for 

 the work, the original being one of the few which were unfortunately 

 destroyed. As it is a faithful copy, the faults of outline are retained ; 

 it was colored, however, from a specimen furnished by myself; the 

 upper surface is thereby much improved, being in the main satisfactory; 

 the under surface of the secondaries is, however, even worse, if anything, 

 than the original, the ground color being given as almost dull olivace- 

 ous, and the marbling represented by coarse irregular blotching rather 

 than by confluent, short, transverse streaks or bars; beyond the middle 

 band the darker colors are just where the lighter ones should be; whitish 

 bands arc given only as very narrowly bordering the middle band, as 1
