thorax. Compound eusternal sclerite subrectangular, two setae on 

 each side. Sternellar sclerite minute, and with a single seta. 



First to seventh ahdominal segments (fig. 23). — The skin between 

 the sclerites rather well developed and the sclerites not so predomi- 

 nating in size as in other species of the genus Galerucella. Com- 

 pound interior prescutal sclerite with one seta on each side ; exterior 

 prescutal sclerite distinct, one seta. Compound interior scuto- 

 scutellar sclerite not so wide as the interior prescutal plate, one 

 seta on each side; exterior scuto-scutellar sclerite nearer the middle 

 line than the exterior prescutal, one seta. Parascutal area with a 

 distinct anterior sclerite, a distinct posterior sclerite which is twice 

 as large, and a small chitinization around the spiracle; anterior 

 eclerite with one seta and posterior with one. Epipleural sclerite 

 round, large, with two setae. Hypopleural sclerite small; one seta. 

 Eusternal compound sclerite oval, about of the same size as in 

 mesothorax and metathorax; one seta on each side. Sternellar area 

 with small, round sclerite, and one seta. 



Eighth abdominal segment. — Similar to the preceding segments 

 but with interior and exterior scuto-scutellar sclerites fused into a 

 single median plate ; two setae on each side. 



Ninth abd&imnal segment. — Pygidial shield with the free margin 

 forming an arc of about 120°. Five long, pointed, marginal setae 

 on each side and two small discal setae on each side. Ventral part of 

 segment with a transverse, band-shaped sclerite; two setae on eacli 

 side 



Tenth ahdominal segment. — Carrying a lateral sclerite on each 

 side ; four anal lobes. 



Habits. — Skeletonizes and eats holes through the leaves of 

 Vihur?ium, opulus and of cultivated species of Viburnum. No definite
