This is a curiously-marked species, of which two specimens ai'e 

 before me. I onlj'^ know of one or two similar instances in which 

 the elytral markings are of two shades amongst the African species 

 of Cryptocephalinse ; as both the specimens are exactly similar 

 in every respect, 1 have no doubt that it is the normal coloration 

 of the species, which wovdd find its place near C. bifasciatus, Fabr., 

 or allies.
