others of the family, are very different in structure to any that I 

 have before observed : the greater part of the last joint being com- 

 posed of rings, which render it perfectly flexible, and enable the 

 insect, I imagine, to use it with nearly the same facility as an ele- 

 phant can his trunk ; and it is necessary to observe that in the view 

 of the underside of the trophi, the maxillae and palpi are repre- 

 sented too far from the lip, occasioned by the pressure used in dis- 

 secting, and the basal joint of the palpus is concealed under the cly- 

 peus, in the profile of the head.

Mr. Haworth possesses a female of this rare insect, taken many

7. C. ornata Meig. — Curtis Brit. Ent.pl. 5. 



The specimen figured in the plate is a male, and was taken upon 

 an oak, by J. C. Dale, Esq. in company with the Rev. W. Kirby, 

 near Lyndhurst in the New Forest, July 7, 1821. It is the only 

 one known to have been found in this country : but I have seen a 

 foreign female of this beautiful species in the collection of the Mu- 

 seum at Edinburgh. The plant is Polygonum avicidare (Common 

 Knotgrass).
