'Buffalo beetle' - Macrosiagon pectinata - female

'Buffalo beetle' - Macrosiagon pectinata - Female
San Pedro River crossing near Hereford, Cochise County, Arizona, USA
July 24, 2013
Note the very uniform convexity of the front of the vertex here...as well as its smoothness/sparsity of punctation. The front of the vertex in M. octomaculata is supposed to be flat to slightly concave...and (perhaps) more densely punctate.
