reaching much beyond the base of the elytra, and their second joint is pro¬ 
portionally shorter, not regularly obconic, but abruptly globular at the 
apex, very slender at the anterior part, whereas it ought to be more elon¬ 
gate and less inflated at the tip, according to the elongation and slender¬ 
ness of all the other joints. There is a tendency to that inflation in the 
two preceding species, but in a much slighter degree, combined with 
greater elongation, as in the other species. 
Stenocerus nigrotessellatus, Blanchard, (d’Orbigny, Voy. dans l’Amer. 
Merid. 1837—43, p. 200, No. 636, tab. xvi. fig. 2). 
A very fine and large species, extremely allied to Sten, testudo , 
in its coloration, but larger (size of Sten. fulvitarsis ), proportionally more 
elongate in the thorax and elytra, the former having the anterior lobe of 
its sides more acutely produced above, the latter are less depressed along 
the suture and at the sides: the thorax is likewise adorned with a semi¬ 
circular ochreous line, and the ochreous dorsal patch of the elytra is of a 
finer and orange hue, on which the black tessellations are much more 
numerous on each row, and consequently more nearly approached each 
other. Its place is between Sten. fulvitarsis and Sten. testudo , in 
the first section, of which it has the proportions of thorax and elytra in a 
lower degree, and it links this section to the second. 
Stenocerus Blanchardi, Jekel. 
Ovato-subparallelus , piceus , infra sparsim , supra dense nigro tomentosus , 
nebula punclisque ordinariis thoracis plagaque elytrorum utrinque 
late emarginata ut in Sten. tessellato delineatis , sed ochrescentibus; 
tliorace minus conico , lateribus sat bisinuatis, cum lobo ante-basali 
semi circular iter, et ante-medio obtuse lateque rotundatis , supra 
medio paullo depresso ; elytris subparallelis , ad suturam mediocriter 
depressis.
