 cream colored, with head and pronotal shield black or brown), the pleural and ven- 

 tral surfaces pale green or cream white. Head pale yellow. Tips of thoracic legs 

 and head brownish yellow. Five pairs of prolegs situated on segments 3, 4, 5, 6,

 lowish, with brown or black markings as follows: Two medial pairs of dot patches, 



the posterior pair nearly touching the posterior margin 

 and somewhat oblong in outline, the anterior pair 

 approaching the anterior margin and linear in out- 

 line, being for the most part made up of a single row 

 of dots; both pairs converging anteriorly, the anterior 

 rows forming a V. Posterior margin bearing four 

 bristles. Two pairs of bristles flanking the anterior 

 median patches of dots, the posterior bristle in each 

 pair short.
