Colevptera from the Ilaioaiiaii Islands. 83 



pean Hydrubius convexus, Bnille, in which species there 

 is likewise a slight ciliation of the hind tarsi. 



Found in Oahu, and probably in other islands of the 

 group. 



2. Cyclonotum suhquadratum, Fairm. 



This species was described by Fairmaire from specimens 

 from Tahiti. I have had no opportunity of comparing 

 Hawaiian with Tahitian individuals. 



This species is common in vegetable refuse. 



3. Sj)hcpridium ahdominale, Fab. {Dactylosternutn,^^ o\\.) 

 This widely-distributed insect is one of the commonest 



beetles at Honolulu^ where it is found, as elsewhere, among 

 rotting vegetables.
