PAPILIO I. 



deep yellow patch at the excavation of abdominal margin ; over this is a black sub- 

 ovate spot enclosing a blue streak or lunule; next above a sinuous crimson bar, 

 the upper edge often bordered by white; the disk opposite this bar irrorated with 

 fine yellow scales. 



Under side much the same in markings, the dark portions decidedly brown, 

 the light bands greenish-yellow more or less tinted with buff ; within the marginal 

 border, anterior to the macular band and to the spots on secondaries, is a reddish-grey 

 stripe se23arated from each of the lunules by a black bar extending across the in- 

 terspace; the limb irrorated with yellow; the crimson bar as above but always 

 broadly edged with white, and nearly or quite connected with a sinuous crimson 

 stripe which runs through the middle of the black band to the costal edge, and is 

 also edged anteriorly by white. 



Body black, the thorax above covered with long yellow-grey hairs, beneath 

 black quite to the head; a narrow yellow stripe passes along the side of thorax and 

 a yellow line starting at the insertion of secondaries passes along the side of abdo- 

 men to last segment; palpi black with yellow hairs interspersed; front of head fur- 

 nisned with long bristling black liairs; antennae reddish; club same above, reddish- 

 brown beneath. 



Female. — Same size and similar in color and markings. 



Sub-variety Abbotii. — Resembles the variety just described except that on 

 upper side of secondaries is a crimson streak, more or less distinct, nearly parallel 

 to abdominal margin. 



In some respects Walshii is further from Tclamonides than the latter is from 

 Ilarcellus. Besides the differences in the tail, the blackness of the body and the 

 bristling front are consi^icuous. More than half the individuals met with are of 

 the narrow tailed variety represented on the plate. 



The egg is pale green, globular, smooth, .016 in diameter. Duration of this 

 state 7 to 8 days. The larva, on emerging from the egg, is black, covered with 

 minute papillae from each of which proceed fine hairs. After first moult, which 

 takes place at three days, it is ash colored, still covered with the j^apillae. These 

 are lost at the second moult, after four days, when the larva assumes the general 

 form and smooth skin which it shows at maturity, the color being yellow-white, 

 with transverse grey stripes. After third moult, which takes jilace in six to eight 

 days, the color is smoky-brown, each segment crossed by four lines of which the 

 anterior is yellow and the rest dull white; the second, third and fourth segments 

 without yellow, and the white lines nearly crowded out by the ex2)anding of the 

 brown; at the junction of fourth and fifth segments is a velvety -black band j^re- 

 ceded by a white on the fourth and followed by a yellow one on the fifth. At the 

 fourth moult, from seven to ten days, the color becomes darker, quite black on the
