flavipes\i0{} was captured by J.F. Stephens near Hastings on August 15th, 
1818, and a scan of his illustration of the specimen is provided here.
The yellow legs streaked with black, the median dorsal yellow markings continued 
beyond the seventh segment to the end of the abdomen, and the different 
arrangement of yellowish stripes on the front of the thorax distinguish the
species from \i{}G. vulgatissimus\i0{}.>
