I had figured this species under the name Chlanius diaphani- 

 collis in the Plate above referred to, which accompanied a pre- 

 vious part of this list. Since then, I learn from M. de Laferte, who 

 possesses the original specimens which belonged to the Count 

 Dejean, that it is identical with the Chl&nius eximius of that 

 author, to which I have accordingly restored it. 



My specimens, however, seem to differ somewhat from the 

 normal type of Dejean. In his the thorax is darker in the 

 middle, while in mine a blackish tint invades both the middle 

 and the base. The yellow markings on the elytra also are not 

 confined to the interstitial spaces specified by Dejean; but as 

 I find my examples to vary in this respect, some having the 

 markings more expanded than others, it is obvious that such 

 differences are not specific.
