THE LEPIDOPTERIST 67 



Eggs began hatching May 18. 1918. Mr. E. A. 

 Dodge of Santa Cruz, Cal. had advised us to try 

 Amorpha canescens for this group C. whitneyi abre- 

 viatella and nuptialis, as he and his brother, the late 

 Geo. M. Dodge, were almost sure that was the food 

 plant. When the first nuptialis hatched we offered 

 it leaves of A. canescens which it refused and died 

 without eating. They hatched slowly one or two 

 at a time, and when the next one hatched on May 

 20th we gave it a leaflet of Amorpha fruticosa which 

 it ate readily. 



The larvae when newly hatched are 1-8 in. long. 

 1st. molt May 25th. 5-16 in. long, body color white 

 striped longitudinally with dark brown lines. 2nd 

 molt, June 1st. The larvae now take on the markings 

 that they keep with a few minor changes through all 

 later molts. 3rd. molt, June 8th. 4th molt, June 

 16th. Spun, June 27th and pupated July 1st. Moth 

 emerged July 27th. 



Mature larva is 2 1-8 in. long. Head white, a gray 

 line slightly divided at the jaws runs through the 

 middle of the face over top of the head. On each 

 side of this a black branching line from back of head 

 down the face nearly to the jaws. A double line out- 

 side of this much branched on back of head extends 

 down the face and connects as one line above the 

 jaws. Still another line outside of this on each side 

 with several short black lines running obliquely along 

 the side of head. Lobes have an orange shade. 



After second and third molt the line running down 

 center of head is black instead of gray and much 

 heavier and extends over the second segment to the 

 third where it branches into the dorsal line of three 

 rows of dark dots. 



This larva is a smooth slender worm Tt has no 

 horn or other elevation anywhere, and has no filli- 

 ments. The ornmentation consists entirely of numer- 

 ous spots or dots arranged in longitudinal bands with 

 the white of the body color showing as narrow lines 

 between. The dorsal line is composed of many fine 

 black dots gradually widening to the 9th segment,
