various Central American Coleoptera.

fourteen Central American Ewpacti, one of which is un- 
known to me. Gorham’s descriptions, it may be observed, 
were mostly made from one specimen, the others placed 
by him under the same name often proving on examination 
to belong to different species. His #. (Mirosternus) laevis 
was from the Antillean island of St. Vincent.
