182 Mr. J. S. Baly on the differential characters 



Gebler in 1823. They agree so closely in all essential 

 characters, and the sulcations of the elytra are so variable 

 in degree and definition, that without hesitation I have 

 placed them lender the same specific head. 



The specimens of var. A. are usually rather smaller 

 than those belonging to the typical form. 



Chrysomela intricata, Germ. 

 Ins. Spec. Nov. 1824, p. 596 ; Suffr. Mon. p. 180. 



Anguste oblonga $ , oblongo-ovata postice paullo am- 

 pliata ? , viridi - aut casruleo-metallica ; thorace trans- 

 verso, rude rugoso-punctato, lateribus intra marginem 

 longitudinaliter sulcatis; elytris subcrebre punctatis, inter- 

 spatiis irregulariter rugosis. 



Mas. — Abdominis segmento anali apice concavo-emar- 

 ginato; telo bre^d, robusto, curvato, apice obtuse angulato. 



Foem. — Abdominis segmento anali apice obtuse rotun- 

 dato. 



Long. 4 — 5\ lin. 



Hab. — Swiss Alps ; Styria. 



The character given in the Synoptical Table so com- 

 pletely separates this species from its congeners that a 

 detailed description is quite unnecessary.
