lilac, each set in a jjale-yellow patch, extends along the middle of the back. The 

 caudal horn is reddish or bluish green, granulated with black in front. Much varia- 

 tion of color occurs among tliese caterpillars. Instead of green they are sometimes of a 

 reddish pink, with markings of darker shades of red or brown. When mature they 

 descend to the ground, where they draw together a few leaves or other material, with 

 threads of silk ; and within these they transform to pupju. 



There are two broods of this insect each year, and they pass the winter in the 

 pupa state. They feed on the leaves of the grape. 



The oleander sphinx (Dellei^hila nerit) belongs to Africa and southern Asia,
