were from three to three and a half inches in length and most of 

 them of a light whitish or yellowish green above and darker 

 green below. Head dark green, with a lateral pink or flesh-col- 

 ored stripe, obcordate, but slightly bilobed at the apex or top. 

 Feet and caudal horn in the majority of the specimens pink or 

 flesh color. In others the horn is green in front with a flesh- 

 colored lateral stripe. Spiracles vermilion, with a white or yel- 

 low central slit. The whole body, except the caudal shield and 

 side plates, smooth (to the eye). Caudal horn with a yellowish 

 green tip and covered with pink and green granules. The seven 

 lateral, oblique bands yellow, with a dark green shade line above, 

 the first six crossing one whole segment and a half of the next. 

 The seventh band is the broadest and brightest and extends to 

 the base of the caudal horn. Caudal shield and plates with black 

 granules. 



One larva was a beautiful brown in color, the shade on the 

 upperside of the bands becoming a deep reddish brown with 

 greenish yellow patches below the bands. Caudal horn and feet 

 bright pink; an indistinct green shade on the upperside of the 

 horn which is long, strong and but little curved in all of the 

 specimens. 



The larva of undulosa changes to a watery purple or red before 

 burrowing to pupate. Pupa from i^ to i^ inches long, dark 

 brown (almost black). Tongue case not apparent. The pupa 

 is shaped much like that of Cerato7nia aniyntor. 



From the eight pupae obtained from the larvae of 1886 but 

 three imagoes emerged in 1887. 



On the 25th of August, 1887, we collected twenty larvae on 

 ash. They were fed in muslin bags on ash and lilac to maturity. 

 The half grown larvae were a beautiful bright yellowish green 

 above, dark green or bluish green from the spiracles down, ex- 

 cept the underside of the third and fourth segments, which were 

 yellowish green and similarly colored above. 



One larva, i^ inches long, was bluish green, with first, second 

 and seventh bands whitish; the others green. Stripes on the 

 head yellow. Spiracles vermilion, with a yellow dot above and 

 below. 



One full grown larva was of a light reddish brown (almost 

 wine color); eight or nine were pale bluish green; the rest light 

 yellowish green. Head reddish or wine color, with a paler lateral
