EARLY STAGES OF MEXICAN LEPIDOPTERA. 



By Wm. Schaus. 



Papilio Daunus, Bdv. Larva. — Length when mature iS/s — 2}{ 

 inches. Head pale brown. On segment 2 are very long retractile 

 tentacles of a brownish color. Body smooth, the fourth and fifth seg- 

 ments being very inflated, the other segments are rather small; color 

 apple-green; on fourth segment are dorsally two small spots of a 

 lighter green, edged by a fine black line and beyond these spots on each 

 side are larger irregular spots of light green also edged by a black line; 

 these latter spots enclose a spot of apple-green edged with black but 

 having also a tiny blue central point; on segment 5, are four dorsal 

 blue points and the segment is bordered posteriorly with light yellow; 

 the sixth segment has anteriorly a broad transverse velvety black band, 

 which joins the fifth segment; segments 8, 9, 10 and 11 have each four 

 small dorsal blue points and seg'ment 13 has a transverse yellowish 

 ridge; laterally beginning at segment 4 is a pale blue point below 

 stigma which is yellow and below these points the ground color is mot- 

 tled with grayish points and lines. Underneath whitish, prolegs white, 

 abdominal legs pale green. Before pupation the colors change, the 

 apple green becoming rich brown, and the light green, yellow; the 

 abdominal legs become gray. The pupa being already known I do 

 not redescribe it. The imago is rare at this low elevation,* being found 

 chiefly on the plains above. 



Papilio Pilumnus, Bdv. Larva. — Length 2 inches, rather slight, 

 though general formation is the same as in the other species of this 

 group. Segments 3, 4 and 5 are thicker, but not so inflated as in 

 Daunus. Head, which is small, and anterior half of second segment 

 are pale brown ; second segment has centrally a transverse yellow ridge 

 and the posterior portion as well as entire rest of body, dorsally, bright 

 green. Anteriorly on segment 4 are two large fawn-color spots, edged 

 with a very fine black line and having within each two black spots, the 

 outer one large and round, the inner one very small and irregular. 

 Dorsally on segments 5 to 12, under side, are four rows of little blue 

 rings placed rather outwardly. Laterally, extending from transverse 

 yellow ridge on segment 2 and passing through stigma and right 

 around last segment is a yellow line; below this and underneath the 

 color is light brown; prolegs and abdominal legs the same. Just below 

 yellow line on segments 6 to 12, inclusive, is a brilliant and rich blue 

 round spot, finely, almost imperceptibly, edged with a black line. Be-
