are rich chestnut brown, mottled with black spots, ol which there is a distinct ■ 

 row. On the anterior portion of the subdorsal region is on each segment a cloud oi 

 white spots, almost lo-t in the ground color. Lateral region fawn-color, very slightly 

 mottled with black, and most prominently so immediately above the abdominal I 'gs, 

 which are fawn-color, with a rich black velvety patch at the side of their middle seg- 

 ments. The thoracic feet are paler with black patches at their base. Caudal horn 

 lull fawn-color, slightly roughened. Underside fawn-color, with black ventral line. 

 and many small black dashes. One of my specimens is paler in the ground color, but 

 there is no difference in the arrangement of the markings. 



Length 50 mm. 



Mature larva.-- In the single specimen of this stage before me, there has come a 

 great change. The ground color is now greenish drab, with yellowish marks con- 

 sisting of slightly roughened patches of that color over the body, enclosing here and 

 there a few brownish dots. The red stain on 3rd segment has disappeared, and the 

 black transverse band enclosing the circular ring is proportionately narrower and 

 smaller. Spiracles brown. 



Length 80 mm. Width 15 mm. 



Pupa.'— Pitchy, lighter across the abdominal segments and wing-covers. Head 

 gradually smaller from its base, rounded very much in front, not swollen ovei the eye- 

 cases. Its divisions are strongly marked, and it is rather rugosely wrinkled. The 

 tongue and antennae cases are distinctly marked. Wing-covers lighter brown with 

 black streaks along the course ol the veins. Thorax slightly raised, rugosely and ir- 

 regularly Wrinkled. Abdominal segments narrowly rugosely-punctate in front, trans- 

 versely wrinkled posteriorly and marked with broken transverse band of black. Last 

 3 segments pitchy, obscuring the markings. Cremaster triangular, rough above and 

 beneath . 



Length 55 mm. Width 15 mm.

Anceryx Ella, L. Larval stages and pupa. 



The Rev. W. J. Holland in Can. Entom., vol. 18, p. 103, has most 

 carefully described the mature larva of this species. I add descriptions of 

 the earlier stages and of the pupa. 



. Ifter jrd moult. — The general color of the 1 irva is either pale sea-green, (green 

 var.) or pale reddish brown, (brown var.). On the head and second segment the 

 brown double line is very distinctly marked, especially in the green form, but on the 

 3rd segment it is nearly lost in the ground color. The round black velvet-like spot 

 on 3rd segment is bordered more broadly behind with yellowish white, and on the 

 sides of this segment are some white blotches standing out m strong contrast with the 

 ground color. The lateral region is mottled with reddish, among which the white 

 blotches appear. The dorsal region has the spots of the segments very small, but 

 there is a faint line of distinct black dots at the anterior edge of each segment. The 

 caudal horn is very long, rough, and smaller through its length than in the more 

 mature stage-. The thoracic feet are reddish brown, banded with a darker color, 

 and the abdominal legs are also reddish brown, broadly banded outside with black. 



Length 40 mm. 



After 4th moult. — The dorsal markings become heavier and more distinct, the 

 black dorsal spot also heavier, the caudal horn very much reduced in length, but
