Early Stages of some North American Moths. 



By Henry Edwards. 



Sphinx Elsa, Strecker. 



Full grozun larva. — Pale apple green, each segment with numerous minute raised 

 tubercles, yellowish, surrounded by a red ring, giving rather a roughened appear- 

 ance to the insect. On the 6 posterior segments is an oblique stripe of reddish brown, 

 edged posteriorly with pale yellow. The stripes on the last 2 segments become con- 

 fluent at the base of the caudal horn, which is unfortunately wanting in the specimen 

 before me. Mouth parts, feet and legs, purplisli brown. 

 Length 70 mm. Width 10 mm. 

 From an inflated specimen prepared by Mr. f. Doll. 



Saturnia Galbina, Clemens. 



Egg- — Depositt-^d in an irregular mass, cream color, slightly flattened at the sides, 

 very glossy. Before the emergence of the young larva the largest circumference of 

 the egg becomes bright chestnut brown, the larva eating a circular hole through 

 which to escape. 



Yoit7ig larva.— VAdicV, sparsely covered with long fawn colored hairs. Head 

 very large, glossy. (Died 2 days after emeigeiice.) 



Cocooti.~Y orxw^A of fine network, white, the outer case also of net work, but tlie 

 meshes much larger and coarser. The silk of which it is composed is stout and 

 strong. The pupa is hardly visible through the cocoon. Length 45 \\\m. Width 

 20 mm. 



Pupa. — 'iiovX, short. Head case rounded in front, the color fawn-drab, with 

 the edges of the wing cases and the posterior margins of the abdominal segments 

 brown. The whole surface is rugosely punctate. Spiracles and cremaster brov.-n. 

 Length 25 mm. Width 12 mm. 



Coloradia Pandora, Blake. 



£gg- — Very large for the size of the imago, round, almost globular, brownish in 

 color and mixed largely with the hairs irom the abdomen of the parent. A gummy 

 secretion is supposed to be deposited with the eggs, as they adhere very firmly to- 

 gether.
