with the basal angles of the scutellum, and joins the extremities of the straight 
one, which passes across a little below the apex of the clavus; marginal nerve,

reticulated with blackish or brownish, Legs black. Cowe, 3rd pair, white or 
yellowish-white. Tibi, base of all the pairs, brownish-yellow ; spines of the 
3rd_ pair, yellow, tips black; fringe black. Tarsi, 3rd pair, 1st joint yellow,

Abdomen black. Length, 24 lines. 
A most remarkable insect, and at once recognisable by its ‘dumpy’ 
form, and the angular black character on the elytra. I have described 
it at length, because I have every belief in its yet being found in

situations, and to occur throughout the whole summer, and as late as 
the end of October.
