APATURA II. 



so expanded next inner angle of primaries as to occupy full half the width of the 

 band. The female is duller colored, but as little obscured as the male. Prinui- 

 ries are crossed by a broad, sinuous, deep black discal band, which in the usual 

 Chjton is brown or ferruginou.^, and the bars in the cell arc black and heavy. A 

 broad, sub-marginal black stripe completely crosses both wings, the nuirgin out- 

 side this stripe l)eing ferruginous concolored with the disk. The crenated line 

 is al)sent from secondaries, even at the outer angle. 



I give this form, therefore, as a possible variety of Clyton, but vi\y opinion is 

 that it will be found to breed true to itself, and, if so, it is a good species. Mr. 

 Stadlmair found these buttertlies in one locality, resting on the leaves of trees, 

 and evidently just out of chrysalis, and saw numbers of them, as he says in a 

 letter to his father. With them were many A. Alicia, of which he took several, 

 and these I also saw. 



Egg. — Similar to that of CMh ; nearly spherical, flattened at base ; marked 

 by about eighteen slightly prominent vertical ribs, and by many fine horizontal 

 equi-distant stria) ; color 3'ellowish-green. Duration of this stage eight to nine 

 days. 



YouxG L.VRVA. — Length, .06 inch; cyHndrical. somewhat tapering posteriorly, 

 slightl}' pubescent; coloi- pale green, translucent; head large, twice the diam- 

 eter of the following segments, hemispherical, bi-lobed, brownish-yellow ; the 

 mandiljlcs and ocelli l)rown. (Figs, c, c^, larva and head magnified.) 



The first moult takes phice in seven days. Length, .125 inch; body tapering 

 gradually either way from seventh segment ; the second and last nearly equal in 

 diameter, the latter terminating in a short, forked tail ; the whole surface cov- 

 ered with fine whitish tubercles, from each of which springs a white hair ; striped 

 longitudinally and alternately with pale and dark green, the tubercles covering 

 the pale stripes densely ; in all there are six pale stripes, two broad, dorsal, one 

 upper and one lower lateral, both narrow ; of the intermediate dark stripes one 

 is a narrow medio-dorsal, the others lateral ; legs and pro-legs pale green, fringed 

 at ))ase with short white bristles; head large, l>roader than the second segment, 

 rounded, flattened, glossy, pale green, the forehead dusted with lu'own ; the 

 ocelli and mandibles brown ; at the vertices fleshy stag-horn processes, with 

 sJiort, stout prongs ; other prongs below at the sides of the face ; all these, and 

 the surface of the face, somewhat pilose. (Fig. d.) 



To tlie second moult thirteen days. Length, .2 inch ; the pale stripes now 

 changed to yellow-green ; the surface more roughly and unevenly tuberculated : 

 the dorsal bands, before distinctly separated, now meet, Init there are traces of a 

 green medio-dorsal line ; the second segment px'ojects over the head a narrow 

 sub-triangular shield ; the tails deeply forked ; the horns sliorter, pinkish, punc- 

 tate ; the forehead aud sutures and the mandibles In'own.
