(which is narrowly infuscate) and partly granuliform, here and there 
(especially at the middle of the sides) transversely confluent. Rings of 
the abdomen having each side a denudate longitudinal macula. An¬ 
terior legs much stronger and longer than the others ; their femora 
armed with two spines transversely placed not far from the apex 
and obliquely inclined forwards, in front of which one or two very small 
teeth are observable; their tibiae abruptly curved at the base, ampliate 
to their anterior third underneath. Femora of the other legs bearing a 
small oblique spine. Posterior femora reaching to the base of the third 
ring of the abdomen* 
* This last character is important, as an accessory to the distinction 
of the various types: in the filiform species, with the apex of the elytra 
singly rounded or obtusely acute and the femora always edentate, the 
posterior femora are hardly as long as the basal ring of the abdomen 
( Bel. jiliformis , Germ., Bel.filum , Jekel, &c.), even in a new species of 
Richmond River extremely short, only reaching to the two-thirds of that 
ring; in the appendiculate species (Sp. 1—3, Sch ., as types) and in 
those where the elytra are conjointly more or less acutely rounded at the 
apex (Bel. melanocephalus , Hope, Sch., Bel. sparsus , Germ., &c.) they 
generally extend to the base — very seldom above the middle — of 
the second ring; in Rhinotia they reach to the two-thirds of the second 
ring; in the groups where the elytra are less elongate and evidently 
wider posteriorly, and with Belus- like antennae (Bel. fumigatus , Germ., 
Bel. irroratus , Jekel, Rhin. pectoralis , Er., Rhin. Dermestiventris , Boisd., 
&c.), they are at least as long as the two basal rings; finally, in 
Pachyra , Hope, far more distant from Belus than Rhinotia , all the legs 
are equally long, their femora and tibiae long, slender, and the abdomen 
being very short relatively to the group, the posterior femora reach above 
the middle of its length.
