distinct tooth ; the basal portion of the elytra is brownish, but the apex is black, 
the black colour occupying nearly the half, the scutellum is also black, and the suture 
is very narrowly blackish. The under-side is black, with the middle and the hind 
angles of the thorax tawny, and the trochanters and extreme base of the femora 
are also of that colour : the last ventral segment is produced into a sharp tooth in 
the middle. 
This species is closely allied to Smilicerus Sallei, Cand., hut has 
the black colour at the extremity of the elytra more extensive, and 
differs also in other small respects, so that I had no doubt when com- 
paring it with the type of S. Sallei in Mr. Janson’s collection, that 
the two were distinct. 
Found at Chontales, in Nicaragua, by Mr. Belt.

S . Antenna) inserted on a long curved process, somewhat below its middle, this 
process is not clavate towards the extremity, but is very densely fringed with long 
pale hairs ; the whole of the upper part of the head is also very densely set with 
such hairs. The thorax has, in the base in front of the middle, a patch of strigose 
punctures divided into two by a fine channel ; the apex of the elytra has, in front 
of the vertical portion, a small tubercle on the alternate intervals, the vertical por- 
tion is densely set with hairs, and its margin simple. 
? . Antenna) inserted as in the male, but the process not quite so long, and its 
fringe not nearly so dense : the upper part of the head has only a few hairs ; the 
patch of strigose punctures on the thorax is quite rudimentary. The elytra are 
rather shorter and rather broader at the apex, the sutural tubercles are separated by 
a wude depression, the vertical apex is less densely pubescent, and its margin is at 
the apex broadly explanate. 
This remarkable member of the Platypides was found at Chontales 
by Mr. Belt, after whom I have the pleasure of naming it. It is one 
of the largest species of the family, and should be placed at the end 
of the genus near Tesserocerus Spinolcc and insignis , but should 
apparently form a distinct section, because the female, as well as the 
male, has the process of the scape much prolonged beyond the point 
of insertion.
