The above insect inhabits Assam. The sexes of the species appear to differ 

 in their antennae, those of the males being more robust, and the elytra an- 

 more acuminated at the external angles. The true Callichroma of Latreille 

 seems confined chiefly to the New World, althougli in modern catalogues wt. 

 find some African species ranged under that generic title. Those species, 

 however, with very conspicuous dilated tibiae ought to be separated from Cal- 

 lichroma, as they evidently belong to a subgenus. jM. Dc Ilaan mentions one 

 Asiatic species in the Leyden collection. In my cabinet there is another 

 elegant insect, which I have named loscelis from its violet-coloured legs : it is 

 likewise from Assam. The present species is named in honour of Dr. Cantor. 

 It is satisfactory to state, tliat liis valuable collection of Repti/ia, with his ex- 

 (juisite drawings, are safely deposited in the Radcliffe Library at Oxford, 



Callichroma Grikkithii.
