Hind wiiiirs witli the apex rounded, Viut the outer edge is very slightly concave, giving a 

 squarish appearance to the wing not present in any species except A. montesuiiia and Si/ssphiux 

 moUna. Colored like the fore wing, but with a large patch of deep pink ))ehind the submedian 

 vein («./■,), and not reaching either the outer or innei- edge of the wing. Beneath, of the same 

 leinon-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 towaiil the base of the wing. Legs: femora yellow, tibire and tarsi pale pink on the 

 outside. 



Expanse of fore wings, S , 84 mm., length Hs nun., breadth 18 nun. Hind wings, length 

 25 mm., breadth 19 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 ditterences; 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, 3a.)

Imago. — 1 S , closel}- resembling .1. hhectn and also hiigd in the shape of the fore wings, 

 but compared with ^1. Imecta the costa is more convex at apex, and the outer edge is more 

 convex, being decidedly so. In the antennw there are 2-2 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 che.stnut brown. Thorax slightly pinkish. Fore wings of a 

 pure chestnut hue, with no flecks, pinkish at base and along the inner edge, including the fringe. 

 Traces of a pinkish l)asal shade. Extradiscal line faint, oblique, ending on the apex; beyond it 

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

 roundish di.scal dot. Hind wings with outer edge full, rounded, though a little angular below 

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

 apparently nuich exaggerated in Herrich-Schaetfer s figures); no lines or discoloration; a little 

 more pinkish on the inner edge. Under side of the wings chestnut brown; no lines, onl\- a very 

 faint extradiscal l)rownish shade on both wings, beyond which the wing is paler, with a slight 

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

 figs. 2, 2«.) 



Expanse of the fore wings, $ , 75 mm. (expanse of 9 according to H.-Schaefler"s figure 

 120 mm.); length of one fore wing, <? , -iO nun.; breadth of one fore wing, S , 20 mm.; length 

 of one hind wing, $ . 28 mm.; breadth of one hind wing, S , 19 mm. 



Geograpliu-nl mxgi/. — Vera Cruz, Mexico, "rare" (Franck); Brazil (H.-Schaeffer); Novo 

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

 Othorene. 



The Mexican form appears to l)e the same as the Brazilian Cadmus, only difl'ering from H.- 

 SchaeHer's figures of the $ in the absence 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 BoisduvaPs descri])tion it difi'ers in not being "d'un gris rose." It maj- be a perma- 

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



He defines th(^ larva^ as having the prothoracic segment provided with sharp spines of 

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