APATURA I. 



two fiiint fuscous spots in the cell ; fringes white in the emarginations, fuscous 

 at the ends of the nervules. 



Under side of primaries chestnut-red at base below the cell ; also within the 

 cell next base, but partly obscured by gray, especially along the sub-costal 

 uervure ; the remainder of the wing pearl-gray, showing a brown sul)-c()lor on 

 the disk and in the middle of each interspace on the apical area, and at inner 

 angle, the gray becoming suffiised with pale blue as it approaches the hind mar- 

 gin ; this margin narrowly edged with yellow-brown ; the sub-marginal lines 

 repeated, distinct, blackish-brown ; the white spots repeated, enlarged, and in 

 addition, a white patch in the line with the outer series, on the costal margin ; 

 the lower spot of this row, on the discoidal interspace, nearly covers a small 

 ocellus, a narrow black ring only being discernible on the anterior side ; but 

 the yellow iris is nearly complete ; the other three ocelli reappear, eidarged, 

 each with its cluster of blue scales and a well-defined yellow iris ; the cellular 

 spots as on upper side, the intervening space being clear white. 



Secondaries pearl-gray, tinted with blue near hind margin ; the gray shade 

 least dense on the disk next before the cell, allowing a brown sub-color to ap- 

 pear ; the inner margin also bordered by a brown line ; the white discal patch 

 and spots repeated, and the line of spots extended across the wing to inner 

 margin, following the course of a dark wavy line ; the spots in the cell distinct, 

 being two transverse bars, each prolonged into the next upper interspace ; the 

 ocelli repeated, each containing a large I^lue patch and edged by a narrow yellow 

 ring, which itself is edged indistinctly by fuscous ; an additional ocellus is found 

 on the inner margin, small, oval, and also with a blue spot. 



Body above yellow-brown, beneath gray on thorax, yellowish on abdomen ; 

 legs ochraceous, the tibii\3 gray ; palpi clear white, brown above and at tip ; 

 antenniB uniform ferruginous throughout, very imperfectly annulated with white 

 next the base ; club fuscous at base, yellow at tip. 



Lakva unknown. 



The figures given represent one of three males, taken by Mr. Henshaw, of 

 Lieutenant Wheeler's expedition, at Camp Lowell, and in Sonoto Valley, Arizona, 

 August, 1874. Nothing is reported of the habits of the butterfly, or of the larva 

 and its food- plant. But as Celtis reticulata, Torrey, is mentioned in the Botan- 

 ical Report upon the ])lants of Arizona, Washington, 1874, it may be presumed 

 that the larvae of Letlla feed upon its leaves. 



In the shape of the wings, this species is nearer Cli/toii than Celtis, the hind 

 margins of primaries being more excavated, and of secondaries more sinuous, 

 and the anal angle more produced than in Cdtls. The three examples agree in 

 shape, color, and markings.
