m. m. wide. When full grown and ready to pupate, the larvae 

 attain a length of 50 m. m.-65 m. m. Otherwise similar to 

 preceding. 



The Pupa. 



The pupae are without a cocoon, being attached by the 

 caudal extremity to some twig or refuse on the ground, of a uni- 

 form rusty brown color, measuring 18 m. m.-22 m. m. in length 

 and 5 m. m.-7 m. m. in width at the widest part. Epicranial 

 suture distinct. C remaster with hooked setae, three on either 

 side. Abdomen more or less punctate. Spiracles brown, 

 ringed with black. 



The Adult. 



Head and thorax with mixed yellow and brown colored 

 hairs. Abdomen almost unicolorous with head and thorax. 

 Ground color of both wings reddish brown to yellow, the brown 

 shades being more prominent near the upper margins of the 

 fore wings. Both upper and under surface of fore and hind 

 wings are profusely speckled with minute black scales which, 

 intermingled with the brown, gives the moth a general pepper 

 and salt appearance. Two adjacent yellow and brown lines 

 run diagonally over the fore and hind wings, starting at the 

 tip of the fore wing, and terminating at the middle of the inner 

 margins of the hind wing. All the wings bear the notched 

 margins as is frequently found in geometer moths. Ex- 

 panse of wings 45 m. m.-48 m. m. Antennae 5 m.m. — 7 m. m.
