The hind margin of the humeral spot commences on the lateral 
margin at a distance from its base of about a fifth of its whole 
length, runs out in a curve (about three-quarters of the distance 
across the elytron) towards the suture, and then proceeds obliquely 
to the scutellum. The post-median fascia is in width about a fifth 
of the length of the suture ; in shape it bears a rough resemblance to 
a horse shoe placed on each elytron with its convexity forward and 
nearly attaining the middle of the elytron. The basal two joints 
of the antennre (in the male) are nearly equal to each other in 
length, and together are quite as long as the head ; the 2nd joint 
is attached to the external corner of the 1st ; on its inner side it 
runs out from close in front of its base nearly at a right angle to 
the line of the antenna, so that hei’e the joint is as wide as 
long, then with a sharp angle its inner outline runs sinuously 
to the narrow apex of the joint ; on its outer side the joint is 
gently curved ; of the remaining eight joints each is more slender 
than the jjreceding one, the 1st and 3rd shorter than the other 5, 
the 1st, 2nd and 3rd sti’eaked with yellow, the apical the longest. 
Differs from all other described Australian species of the genus, 
iyiter alia, by its greatly superior size.
