PAPILIO III. 



AJAX.— Var. jVIARCELLUS, Boisduval. 



Primaries in both sexes equally and largely produced, liind margins much 

 excavated; costa less arched than in Tclamonides; secondaries more jiroduced; tail 

 longer and broader; thorax covered with short hairs; frontal hairs very short. 



Male. — Exjiands from 3.2 to 3.5 inches. 



Color deep black, the borders and black bands broader than in either of the 

 other varieties; the liglit portions pale blue-green in fresh specimens; the stripe be- 

 tween the forks of mesial black band reduced to a mere streak; the two common 

 green bands terminate on secondaries higher up the wing by nearly the width of 

 one interspace; the tail very long and broad, bordered and edged as in Tclamonides; 

 the crimson band reduced to a single lunate spot of variable size, and occasionally 

 wanting, with very rarely a second spot, always minute; the two middle lunules 

 on the margin distinct, the other two more or less obsolete; a greenish band at 

 base of both wings, on secondaries following the edge of the abdominal fold. On 

 the under side the light portions tinted with buff, especially on costa and along the 

 j^rincipal nervures and either edge of the black common band; two crimson anal 

 spots; otherwise as in Telumonkles. 



Body above black, the thorax covered with short grey hairs; beneath wholly 

 bright yellow, excejit a narrow black stripe extending from the head to end of ab- 

 domen, 23assiug beneath the insertion of the wings, and a stripe along lower j^art 

 of thorax and abdomen; a short black line inside the yellow space just before the 

 last segment of the abdomen; palpi yellow; front of head furnished with very short 

 hairs, blaok in front interspersed with yellow next the eyes; antennaj reddish; club 

 same, reddish-brown beneath. 



Female. — Expands 3.5 inches. 



The green bands of deeper color and narrower, leaving the surface very black. 

 In many cases the green shade is rejilaced by a soiled or bufi'-white with no trace 

 of green. The second crimson sjiot appears more often than in the male. 



MarceUus differs from the other varieties by its increased size and blackness 

 of wings and by their shajie in both sexes, by the absence more or less complete of 

 one or two of the yellow marginal lunules, by the substitution of a single large lu- 

 nate crimson spot, occasionally accompanied by a crimson point, in place of bar of 

 Wahhii, or the double and usually equal spots of TcIamo7ikles. It also differs from 

 the latter in the proportionate length and breadth of tail; is still more yellow on 

 throat and thorax; the short frontal hairs are yellow and black, and the palpi 

 are vellow.
