The monograph of this genus, published by Handlirsch,* necessitated the working-up of the unidentified species in the collectin of the American Entomological Society. This author has merged several genera intoGorytes, viz.,Euspongus,Hoplisus, etc. I have followed him, as several of the species described herein belong to what was once the genusHoplisus. There are serveal other new species contained in the Society's collection, represented by single specimens only.
