Type in the collection of the Hawaiian Entomological So- 

 ciety ; paratypes in the Bishop Museum, Honolulu. Described 

 from six specimens (some of them broken) collected by Pro- 

 fessor W. A. Bryan, under bark of Broussonetia papyrifera. 



The genus Sericotrogus was erected by Wollaston in 1873 

 for the New Zealand species subaenescens. Several other 

 species were described later on by Sharp and Broun, all from 

 New Zealand. Some of these have been removed to other 

 genera. The present species has resemblances to the other 

 species of the genus, but differs from one and another of them 

 in some details. It does, not agree with the descriptions of the 

 genera to which the species have been assigned that have 

 been removed from Sericotrogus, and it may meet the fate of 

 these, for it does not more nearly in all particulars exactly 

 agree with Wollaston's description of Sericotrogus than some 

 of them did.
