and deeply sculptured, with a broad groove along the middle in front. Elytra elongate, 
quite black, dull, with a conspicuous raised costa along the middle of each, sparingly 
and coarsely punctured. Hind body with the apical segments shining and obsoletely 
sculptured; basal segment dull, with some large depressions. Unique. 
8. Glyptoma cribellum. 
Piceum, opacum; capite nigricante undique fortiter punctato; abdomine equaliter, densissime, fortissime 
profundeque punctato. 
Long. 24 millim. 
Hab. Guatemata, El Tumbador, Zapote, Capetillo (Champion); Panama, Volcan de 
Chiriqui (Champion). 
Antenne rather short, sparingly setose ; joints 2-10 differing little from one another, 
strongly transverse. Head black, closely and deeply punctured, slightly shining. 
Thorax rugose, without depressions or channel. LElytra longer than the thorax, 
longitudinally rugose, with a well-marked costa along the middle of each. Hind body 
above and below, together with the breast, remarkably densely, deeply, and coarsely 
punctate-rugose ; terminal segment very setose. 
Of this species, so very distinct by the sculpture, Mr. Champion obtained a dozen 
examples at El Tumbador, and one each from the other localities ; I regret to say that 
I lost the unique Panama exponent after determining it.
