of the Amazon Valley. 17 
A widely distributed insect in the Amazons region, being 
found on the banks of the Tapajos and near Ega on the Upper 
Amazons. The species has also been met with by M. Bar in the 
interior of French Guiana. Cayenne examples agree precisely 
with those found at Ega; but those brought from the Tapajos 
are much lighter in colour, and have many tawny spots on the 
upper surface of the thorax and elytra, which are wanting in 
those of other localities.
