of Jeannel (1936) which mostly inhabits South America. The 
two known Lesser Antillean Dissochaetus ( granadensis Jeannel 
1936 of Granada and smithi Jeannel 1936 of St. Vincent) are in 
this group, and suggest initial colonization of Puerto Rico either 
directly from South America or indirectly by-way of the Lesser 
Antilles. However, the possibility cannot be excluded of the beetles 
having reached Puerto Rico either directly or by way of other 
Greater Antillean Islands from Central America or Mexico. The 
Dissochaetus of these later three groups are yet too poorly known 
to evaluate the faunal relationships.
