P. perplexus, D. § S.—Hasily separated from clavatus 
by the continuous band across the apex of the clavus and 
corium, otherwise exceedingly like it ; it is, however, rather 
smaller, and less pubescent, destitute of the fine golden 
hairs of clavatus, the colour rather brighter, the head and 
pronotum scarcely bronzy, and the second joint of the 
antenne slightly less clavate; it is also more variable in 
colour.
