llah. Peru, Sarajacu ; and (?) Cayenne. 



Head witli strong mandibles and prominent cheeks. 

 Disk of the prothorax with about seven sliglitly raised plaga3 

 or flattened tubercles, which are separated from one another 

 Ly narrow sulcate intervals ; the medio- basal plaga is some- 

 what rhomboidal iu form, with its longer diameter in the middle 

 line ; the two in front of its anterior angle are small and 

 scarcely separated from each other ; the two on either si le of 

 the median plaga are broad. The sides of the prothorax are 

 somewhat uneven. The elytra have a dense greyish pubes- 

 cence. The intermediate femora are unispinose, the posterior 

 bis[)inose at the distal extremity. Tiie tibia? are each spined 

 at their outer termination. The antennas, a little lon^rer than 

 the body, are fringed with fulvous hairs underueath. 



This species, in the sculpture of its prothorax and in its 

 general appearance, somewhat resembles G. rhinoceros^ Bates. 

 But the latter species is characterized by the remarkable 

 horn-like processes which come off from the anterior side of 

 the mandibles. In the larger of the two specimens which I 

 have included in the present species there is a slight elevation 

 or ridge on the anterior side of the mandibles.

Rufo-testaccum, clytris fulvis ; capito protlioracecjue fulvo-griseo 

 dense pubescentibus ; prothorace subquadrato, fortiter sparsinKpie

 apicibus truncatis, utrisque bispinosis ; corpore subtus sparsiiu 

 pubescente; feraoribus intermediis apice unidentatis, poi^ticis 

 bidentatis ; tibiis apice cxtus spinosis; antcnnis quam corpore 

 paullo longioribus, t'ulvo sparsim pilosis. 



Hah. Brazil. 



From its general appearance, and especially from the rather 

 close apjtroximation of the antennal tubercles, this species 

 might be considered to belong to the genus SphaUenum ; but 

 as its intermediate cotyloid cavities are not closed externally, 

 the species could not be placed in Spliallenuut without breaking 

 through the limitation which Mr. Bates has imposed upon 

 the latter genus.
