Genus CHOERORRHINODES Champion, 1914

This genus was erected by Champion (Linn. Soc. London, Trans., Zool. II, 16:458, 1914) to receive a new species (genotype C. tenuiculus ) from the Seychelles. It has remained monotypic until now. Three Guam species are described here as new and assigned to the genus. It is with some diffidence, however, that I place all three species in the genus because of their structural differences, some of which may necessitate their removal from the genus when our knowledge of the Cossoninae is more complete and the genera more adequately studied and defined. This extreme discontinuous distribution will, I believe, surely be reduced when collections from intervening areas are studied. I have, unfortunately, not seen a specimen of the genotype which was described from a unique, but Sir Guy Marshall has kindly compared my specimens with it.
