Many examples. In the elevated antenniferous tubers 

 and sculpture, the species resembles the genus Myoxinus ; 

 but the longer and more gradually clavate scape of an- 

 tennae, and simple mesosternum, bring it within the 

 definition of Gen. Aljjhus. 



Alphus centroUneatus, Bates, Ann. N. H. Feb. 1862. 

 — Found also in Venezuela, and in the Amazons region. 

 It would belong to Fycnomorplms, Thoms., but I hold 

 this to be a wholly untenable genus.

 p. 854. — Also found in Mexico and Honduras. 



Steirastoma senex, White, Cat. Long. Col. Brit. Mus.
