dentated exteriorly, but not as deeply notched as in cerysii, but more so than 

 ophthalmicus. Pointed apically more as in the latter, not so squarely cut oif as 

 in cerysii. Secondaries larger in proportion and more evenly cut on outer edge. 

 Upper surface : ground color whitish gray, variegated with brownish shades and 

 bands as in cerysii aad ophthalmicus, not as much broken and zigzag as in the 

 first, neither as clearly defined as in the last; the white discal line and accom- 

 panying line extending half way along the median nervure are boldly defined 

 as in cerysii. Secondaries rosy with white at inner margin, grayisli at costa and 

 inclined to brownish at exterior margin. An anal ocellus black, with a bi-sected 

 blue ring enclosing large black cetitre; fringe white. Under surface resembles 

 closely that of the two allied species alluded to." 



Hab. — Colorado ; near Denver (Bruce). 



Mr. Strecker, whose description is quoted, carefully discusses the 

 question as to whether it might not be an intermediate form or a 

 hybrid between the species with which he compared it. 



Mr. Strecker's expressed belief that cerysii and ophthalmicus may 

 prove varieties of the same species I am scarcely able to agree to, and 

 the differences seem too great to be easily bridged. 



A specimen seen in Mr. Graef's collection proves it a variety of 

 cerysii.

Head sunken, moderate in size ; palpi in the male reaching to the 

 middle of the front ; in the female scarcely exceeding front ; tongue 

 rudimentary ; antennse fusiform, curved at tip ; ciliate in the male, 

 simple in the female; vestiture fine and dense, forming a very dis- 

 tinct crest between the antennae. Thorax moderate, convex, a some- 

 what elevated, obtuse ridge extending its full length. Abdomen 

 elongate, slender, conic, pointed, untufted. Legs subequal, anterior 

 rather the stoutest, unarmed ; middle and hind tibite with a pair of 

 minute spurs at tip. Primaries narrow, inner margin sinuate, the 

 anal angle produced ; outer margin very oblique, varying from regu- 

 larly crenulated (^excrecatus), to an almost even one {astylus % ) ; 

 eleven veined, disposition of veins not essentially different from the 

 others of the subfamily. Secondaries almost subquadrate, the costal 

 margin sinuate, roundedly ])roduced upward at apex ; the costal vein 

 sinuate to accommodate itself to the margin, else essentially as in its 

 allies. Genitalia of the male with side pieces narrowing to an ob- 

 tusely rounded tip, upper margin nearly straight ; a broad corneous 

 process various in shape from the middle of the inferior margin.
