Hind wings with the apex rounded, but the outer edge is veiy slightly concave, giving a 

 squarish appearance to the wing not present in any species except A. inontezuma and Syssjthhi.r 

 ■t/io///Hi. Colored like the fore wing, hut with a large patch of deep pink behind the sul)median 

 vein {a.i\), and not reaching either the outer or inner edge of the wing. Beneath, of the same 

 lemon-yellow hue as above, a moderately large black discal spot, with an irregular eccentric white 

 spot between it and the base; behind the median vein a pink-red patch. Extradiscal line distinct 

 toward the apex, but obsolete toward the hinder edge. Hind wings uniformly lemon yellow, 

 duller toward the base of the wing. Legs: femora yellow, tibia? and tarsi pale pink on the 

 outside. 



Expanse of fore wings, i , Si mm., length oS mm., breadth IS mm. Hind wings, length 

 25 mm., breadth 1!» mm. 



In Druce's figure a basal line on the fore wing is represented. The 9 is the same but 

 larger, with the usual sexual ditierences; the outer edge of the hind wings is full and convex, 

 while the fore wings are more obtuse. (For the venation see PI. LVII, figs. 3, Sa.)

Imago. — 1 i , closely re.sembling ^1. hisectn and also /i(if/i'i in the shape of the fore wings, 

 but compared with ^1. hlxecta the costa is more convex at apex, and the outei' edge is more 

 convex, l)eing decidedh* .so. In the antenntt there are 22 pairs of pectinations, and the filiform 

 tip is composed of about 15 joints, with short toothlike vestigial pectinations on the outside. 



Body and wings of a pinkish chestnut bi-own. Thorax slightly pinkish. Fore wings of a 

 pure chestnut hue, with no fiecks, pinkish at l)ase and along the inner edge, including the fringe. 

 Traces of a pinkish basal shade. Extradiscal line faint, oblicpie, ending on the apex; beyond it 

 the wing is washed with pink, but the fringe on the outer edge is pale chestnut: a minute white 

 roundish discal dot. Hind wings with outer edge full, rountied, though a little angular below 

 the apex and inclined to be very slightly excavated behind the middle of outer edge (this is 

 apparently much exaggerated in Herrich-Schaeff'er's figures); no lines or di-^coloration; a little 

 more pinkish on the inner edge. Under side of the wings chestnut brown: no lines, only a verj' 

 faint extradiscal brownish shade on botli wings, beyond which the wing is paler, with a slight 

 pinkish tinge: costa of hind wings pinkish. Legs pinkish. (For the venation see PI. LVII, 

 figs. 2, 2*/.)

Geographical range. — Vera Cruz, Mexico, "rare" (Franck); Brazil (H.-Schaefl'er); Novo 

 Friburgo, near Rio Janeiro. Brazil (Boisduval). This species is the type of Boisduval's genus 

 Othorene. 



The Mexican form appears to be the same as the Brazilian Cadmus, only ditiering from H.- 

 Schaefl'er's figui'es of the $ in tlie al)sence of a stigma, and in the basal two-thirds of the hind 

 wings not being so distinctly pinkish, while the hind wings are not so angular. 



From Boisduval's description it diflers in not being "d'un gris rose." It may be a perma- 

 nent climatic variety, and if found to be distinct may be named castanea. 



He defines the larv;* as having the protiioracic segment provided with sharp spines of 

 moderate length; the two following segments with dentate spines and the abdominal segments
