primus elongatus, secundus brevis, tertius sex sectiones 
habens, basi productus, apice valdé dilatatus, cui pars intus

Male.—Head black, with a square patch of cinereous hairs 
below the insertion of the antenne. Scutellum black, with the 
points yellow, and sometimes a slight connecting line between 
them, and two dots of the same colour. Base of femora and 
apex of tibize black. 
Female.—Head transverse, with a yellow band behind the eyes, 
and a broad band of same colour down the front with a black line. 
Antenne black. Thorax black, covered with cinereous hairs 
above and below. Scutellum yellow, armed with two points, and 
a black marking at the base. Second, third, and fourth segments 
of abdomen having on each side a somewhat triangular yellow
