In the markings of the elytra this insect approaches the C. chi- 

 loleuca^ Dej. very closely. Independently hosvever of that insect 

 being a Russian species, the present exhibits a marked distinction 

 in the colour of the aniennw and tibiw^ which I have particularized 

 in the specifick description. I have observed the insect only in 

 the collection before alluded to, which was formed by Captain 

 Lyon in his travels into Barbary : and I have named it in honour 

 of that intrepid officer, whose spirit of enterprize has led him into 

 the most unpropitious quarters of the globe, from the burning 

 sands of Africa to the frozen shores of the Arctick regions.
